Abstract
INTRODUCTION Headache is a frequent symptom of infections. We aimed to characterize the clinical phenotype and duration of headache attributed to influenza infection. METHODS Prospective cohort study done in 53 primary care centers between January and April 2023. Patients were included if they had a confirmed influenza diagnosis, were older than 15 years and had a new-onset headache. Patients' demographics, prior medical history, headache phenotype and duration, associated symptoms and patients' outcomes were assessed. The International Classification of Headache Disorders criteria for headache attributed to a systemic viral infection, migraine and tension-type headache were assessed. RESULTS Of the 478 patients 75 fulfilled eligibility criteria. The mean age was 43, 56% were men, and 27% had a prior headache history. The headache phenotype was a bilateral headache (52%), with frontal topography (48%), pressing quality (61%), moderate intensity, rhinorrhea (79%), nasal congestion (76%), and photophobia (59%). All patients fulfilled headache attributed to acute systemic viral infection criteria, 43% fulfilled migraine criteria and 31% tension-type headache criteria. The median duration of the headache was four (Inter-quartile range: two-six) days. CONCLUSION The clinical phenotype of headache attributed to influenza infection was similar to other infections, with more pronounced cranial autonomic symptoms. The headache was an early symptom and was self-limited within a few days.Trial Registration: The study protocol is registered in ClinicalTrial.gov (NCT05704335).

Abstract
Following the waning severity of COVID-19 due to vaccination and the development of immunity, the current variants of SARS-CoV-2 often lead to mild upper respiratory tract infections (MURTIs), suggesting it is an appropriate time to review the pathogenesis and treatment of such illnesses. The present article reviews the diverse causes of MURTIs and the mechanisms leading to symptomatic illness. Different symptoms of MURTIs develop in a staggered manner and require targeted symptomatic treatment. A wide variety of remedies for home treatment is available, including over-the-counter drugs and plant-derived substances. Recent pharmacological research has increased the understanding of molecular effects, and clinical studies have shown the efficacy of certain herbal remedies. However, the use of subjective endpoints in these clinical studies may suggest limited validity of the results. In this position paper, the importance of patient-centric outcomes, including a subjective perception of improved well-being, is emphasized. A best practice approach for the management of MURTIs, in which pharmacists and physicians create an improved multi-professional healthcare setting and provide healthcare education to patients, is proposed. Pharmacists act as first-line consultants and provide patients with remedies, considering the individual patient's preferences towards chemical or plant-derived drugs and providing advice for self-monitoring. Physicians act as second-line consultants if symptoms worsen and subsequently initiate appropriate therapies. In conclusion, general awareness of MURTIs should be increased amongst medical professionals and patients, thus improving their management.

Design, synthesis, and molecular docking of novel pyrazole-chalcone analogs of lonazolac as 5-LOX, iNOS and tubulin polymerization inhibitors with potential anticancer and anti-inflammatory activities. Bioorg Chem 2022; 129:106171. [PMID: 36166898 DOI: 10.1016/j.bioorg.2022.106171] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Revised: 09/15/2022] [Accepted: 09/17/2022] [Indexed: 11/22/2022]
Abstract
Uncontrolled inflammation predisposes to pleiotropic effects leading to cancer development thanks to promoting all stages of tumorigenesis. Therefore, cancer-associated inflammation has been delegated as the seventh hallmark of cancer. Thus, raging the war against both inflammation and cancer via the innovation of bioactive agents with dual anti-inflammatory and anticancer activities is a necessity. Herein, a novel series of pyrazole-chalcone analogs of Lonazolac (7a-g and 8a-g) have been synthesized and investigated for their in vitro anticancer activity against four cancer cell lines using the MTT assay method. Among all, hybrid 8g was the most potent against three cancer cell lines, HeLa, HCT-116, and RPMI-822 with IC50 values of 2.41, 2.41, and 3.34 µM, respectively. In contrast, hybrid 8g showed moderate inhibitory activity against MCF-7 with IC50 28.93 μM and with a selectivity profile against MCF-10A (non-cancer cells). Mechanistically, hybrid 8g was the most potent inhibitor against tubulin polymerization (IC50 = 4.77 µM), suggesting tubulin as a molecular target and explaining the observed cytotoxicity of hybrid 8g. This was mirrored by the detected potent pre-G1 apoptosis induction and G2/M cell cycle arrest. Moreover, hybrid8gexhibited selectivity against COX-2 (IC50 = 5.13 µM) more than COX-1 (IC50 = 33.46 µM), indicating that 8g may have lower cardiovascular side effects, but is still not potent as celecoxib (COX-2 IC50 = 0.204 µM, COX-1 = 35.8 µM). Notably, hybrid 8g showed promising inhibitory activity towards 5-LOX (IC50 = 5.88 µM). Finally, the anti-inflammatory activity of hybrid8 g was confirmed by high iNOS and PGE2 inhibitory activities in LPS-stimulated RAW cells with IC50 values of4.93 µM and 10.98 µM, respectively, that accompanied by showingthe most potent inhibition of NO release (70.61 % inhibition rate). Molecular docking studies of hybrid 8g confirmed good correlations with the executed biological results. Furthermore, hybrid 8g had good drug-likeness and suitable physicochemical properties. Taken together, the combined results suggested hybrid8gas a promising orally administered candidate in the journey of repurposing NSAIDs for cancer chemopreventionand treatment.

Abstract
Given the substantial cost and low success rate of drug discovery and development, repositioning existing drugs to treat new diseases has gained significant attention in recent years, with potentially lower development costs and shorter time frames. Natural products show great promise in drug repositioning because they have been used for various medical purposes for thousands of years. In this review, we discuss the drug repositioning of six prototypical natural products and their derivatives to reveal new drug-disease associations. We also highlight opportunities and challenges in natural product-based drug repositioning for future reference.

Abstract
BACKGROUND Although combination formulas containing antihistamines, decongestants, and/or analgesics are sold over-the-counter in large quantities for the common cold, the evidence for their effectiveness is limited. This is an update of a review first published in 2012. OBJECTIVES To assess the effectiveness of antihistamine-decongestant-analgesic combinations compared with placebo or other active controls (excluding antibiotics) in reducing the duration of symptoms and alleviating symptoms (general feeling of illness, nasal congestion, rhinorrhoea, sneezing, and cough) in children and adults with the common cold. SEARCH METHODS We searched CENTRAL, MEDLINE via EBSCOhost, Embase, CINAHL via EBSCOhost, LILACS, and Web of Science to 10 June 2021. We searched the WHO ICTRP and ClinicalTrials.gov on 10 June 2021. SELECTION CRITERIA Randomised controlled trials investigating the effectiveness of antihistamine-decongestant-analgesic combinations compared with placebo, other active treatment (excluding antibiotics), or no treatment in children and adults with the common cold. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We assessed the certainty of the evidence using the GRADE approach. We categorised the included trials according to the active ingredients. MAIN RESULTS We identified 30 studies (6304 participants) including 31 treatment comparisons. The control intervention was placebo in 26 trials and an active substance (paracetamol, chlorphenindione + phenylpropanolamine + belladonna, diphenhydramine) in six trials (two trials had placebo as well as active treatment arms). Reporting of methods was generally poor, and there were large differences in study design, participants, interventions, and outcomes. Most of the included trials involved adult participants. Children were included in nine trials. Three trials included very young children (from six months to five years), and five trials included children aged 2 to 16. One trial included adults and children aged 12 years or older. The trials took place in different settings: university clinics, paediatric departments, family medicine departments, and general practice surgeries. Antihistamine-decongestant: 14 trials (1298 participants). Eight trials reported on global effectiveness, of which six studies were pooled (281 participants on active treatment and 284 participants on placebo). The odds ratio (OR) of treatment failure was 0.31 (95% confidence interval (CI) 0.20 to 0.48; moderate certainty evidence); number needed to treat for an additional beneficial outcome (NNTB) 3.9 (95% CI 3.03 to 5.2). On the final evaluation day (follow-up: 3 to 10 days), 55% of participants in the placebo group had a favourable response compared to 70% on active treatment. Of the two trials not pooled, one showed some global effect, whilst the other showed no effect. Adverse effects: the antihistamine-decongestant group experienced more adverse effects than the control group: 128/419 (31%) versus 100/423 (13%) participants suffered one or more adverse effects (OR 1.58, 95%CI 0.78 to 3.21; moderate certainty of evidence). Antihistamine-analgesic: four trials (1608 participants). Two trials reported on global effectiveness; data from one trial were presented (290 participants on active treatment and 292 participants on ascorbic acid). The OR of treatment failure was 0.33 (95% CI 0.23 to 0.46; moderate certainty evidence); NNTB 6.67 (95% CI 4.76 to 12.5). Forty-three per cent of participants in the control group and 70% in the active treatment group were cured after six days of treatment. The second trial also showed an effect in favour of the active treatment. Adverse effects: there were not significantly more adverse effects in the active treatment group compared to placebo (drowsiness, hypersomnia, sleepiness 10/152 versus 4/120; OR 1.64 (95 % CI 0.48 to 5.59; low certainty evidence). Analgesic-decongestant: seven trials (2575 participants). One trial reported on global effectiveness: 73% of participants in the analgesic-decongestant group reported a benefit compared with 52% in the control group (paracetamol) (OR of treatment failure 0.28, 95% CI 0.15 to 0.52; moderate certainty evidence; NNTB 4.7). Adverse effects: the decongestant-analgesic group experienced significantly more adverse effects than the control group (199/1122 versus 75/675; OR 1.62 95% CI 1.18 to 2.23; high certainty evidence; number needed to treat for an additional harmful outcome (NNTH 17). Antihistamine-analgesic-decongestant: six trials (1014 participants). Five trials reported on global effectiveness, of which two studies in adults could be pooled: global effect reported with active treatment (52%) and placebo (34%) was equivalent to a difference of less than one point on a four- or five-point scale; the OR of treatment failure was 0.47 (95% CI 0.33 to 0.67; low certainty evidence); NNTB 5.6 (95% CI 3.8 to 10.2). One trial in children aged 2 to 12 years, and two trials in adults found no beneficial effect. Adverse effects: in one trial 5/224 (2%) suffered adverse effects with the active treatment versus 9/208 (4%) with placebo. Two other trials reported no differences between treatment groups. AUTHORS' CONCLUSIONS We found a lack of data on the effectiveness of antihistamine-analgesic-decongestant combinations for the common cold. Based on these scarce data, the effect on individual symptoms is probably too small to be clinically relevant. The current evidence suggests that antihistamine-analgesic-decongestant combinations have some general benefit in adults and older children. These benefits must be weighed against the risk of adverse effects. There is no evidence of effectiveness in young children. In 2005, the US Food and Drug Administration issued a warning about adverse effects associated with the use of over-the-counter nasal preparations containing phenylpropanolamine.

Novel quinoxaline derivatives as dual EGFR and COX-2 inhibitors: synthesis, molecular docking and biological evaluation as potential anticancer and anti-inflammatory agents. RSC Adv 2022; 12:25204-25216. [PMID: 36199335 PMCID: PMC9443684 DOI: 10.1039/d2ra04498f] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Accepted: 08/30/2022] [Indexed: 01/04/2023] Open
Abstract
Novel quinoxaline derivatives (2a–d, 3, 4a, 4b and 5–15) have been synthesized via the reaction of 4-methyl-3-oxo-3,4-dihydroquinoxaline-2-carbohydrazide (1) with different aldehydes, ketones, diketones, ketoesters, as well as hydrazine, phenyl isothiocyanate, carbon disulphide. The synthesized products have been screened for their in vitro anticancer and COX inhibitory activities. Most of the synthesized compounds exhibited good anticancer and COX-2 inhibitory activities. MTT assay revealed that compounds 11 and 13 were the most potent and exhibited very strong anticancer activity against the three cancer cell lines with IC50 values ranging from 0.81 μM to 2.91 μM. Compounds 4a and 5 come next and displayed strong anticancer activity against the three cancer cell lines with IC50 values ranging from 3.21 μM to 4.54 μM. Mechanistically, compounds 4a and 13 were the most active and potently inhibited EGFR with IC50 = 0.3 and 0.4 μM, respectively. Compounds 11 and 5 come next with IC50 = 0.6 and 0.9 μM, respectively. Moreover, compounds 11 and 13 were the most potent as COX-2 inhibitors and displayed higher potency against COX-2 (IC50 = 0.62 and 0.46 μM, respectively) more than COX-1 (IC50 = 37.96 and 30.41 μM, respectively) with selectivity indexes (SI) of 61.23 and 66.11, respectively. Compounds 4a and 5 comes next with IC50 = 1.17 and 0.83 μM and SI of 24.61 and 48.58, respectively. Molecular docking studies into the catalytic binding pocket of both protein receptors, EGFR and COX-2, showed good correlation with the obtained biological results. Parameters of Lipinski's rule of five and Veber's standard were calculated and revealed that compounds 4a, 5, 11 and 13 had a reasonable drug-likeness with acceptable physicochemical properties. Therefore, based on the obtained biological results accompanied with the docking study and physicochemical parameters, it could be concluded that compounds 4a, 5, 11 and 13 could be used as promising orally absorbed dual anti-inflammatory agents via inhibition of COX-2 enzyme and anticancer candidates via inhibition of EGFR enzyme and could be used as a future template for further investigations. Novel quinoxaline derivatives (2a–d, 3, 4a, 4b, 5–15) have been synthesized and screened for their in vitro anticancer and COX-2 inhibitory activities. Compounds 4a, 5, 11 and 13 proved to be the most potent anticancer and COX-2 inhibitors.![]()

Abstract
BACKGROUND Common cold is a frequent illness in northern hemisphere between late autumn and early spring. Patients suffering from it frequently turn to pharmacists instead of physicians in order to receive medical advice and treatment. We studied its treatment advised by pharmacists in Poland, as well as evidence for the efficacy of their recommendations by utilizing a self-developed questionnaire and a study of existing literature. METHODS The data were collected by 27 pharmacists who worked in four large network community pharmacies in Lodz, Poland. The study took place from December 2019 to February 2020. Data were recorded only if the patient asked for pharmacy counselling for over-the counter (OTC) products due to common cold self-diagnosis and a product was sold. Pharmacists' recommendations were compared with the results of a literature review of best evidence to determine appropriateness of the pharmacists' decisions. RESULTS In four out of five cases the pharmacists recommended products contained paracetamol. In addition, in one out of three patient encounters they advised nasal decongestant, inosines and/or OTC mucolytics. There was a significant relationship between fever and recommendation frequency of some analgesics, inosines, mucolytics and sore throat products (OR > 1, p < 0.05); rhinorrhea and recommendation frequency of paracetamol, inosines, anti-histamines and alpha-mimetics (OR > 1, p < 0.05); cough and recommendation frequency of paracetamol, inosines, mucolytics and sore throat products (OR > 1, p < 0.05); and fatigue and recommendation frequency of paracetamol, acetylsalicylic acid, inosines and sore throat products (OR > 1, p < 0.05). The pharmacist recommendations were based on patients' symptoms, product price, pharmaceutical company promotion and the financial incentive. In many cases their recommendations were not in line with current best practice recommendations. CONCLUSIONS Our study suggests that the most common rationale for pharmacist recommendation on anti-common cold treatment was to take a "shotgun" approach. Pharmacists commonly made recommendations for products that lack strong evidence for efficacy (i.e. anti-viral agents) and are potentially unnecessary, based on presentation of the symptom. Reasons for this situation include lack of training, lack of time to evaluate the patient, lack of awareness of evidence as well as drug company marketing and financial incentives (i.e. fulfilling sale plans and target sale bonuses). TRIAL REGISTRATION The study was a non-interventional, observational research trial. The study registration was not required.

Abstract
BACKGROUND The consumption prevalence of OTC medication ranges between 57% and 78% among adolescents in the United States of America; however, the reasons for self-medication with OTC analgesics have not been systematically examined. AIMS The purpose of this meta-synthesis is to generate new knowledge and theoretical understanding of adolescents' use of over-the-counter (OTC) analgesics. DESIGN Qualitative meta-ethnography using Noblit and Hare's (1988) approach. SETTINGS PARTICIPANTS/SUBJECTS: METHODS: We identified qualitative studies in the CINAHL, PubMed, PsycINFO, and ProQuest Dissertation and Thesis databases that addressed OTC analgesic use in adolescents, were published between 2006 and 2018, and were written in English. Themes were extracted from studies meeting inclusion/exclusion criteria and a meta-ethnographic analysis was conducted. RESULTS Seven studies met inclusion/exclusion criteria. Four themes were identified that described reasons for adolescent use of OTC analgesics for pain management: 1) survival instinct; 2) placebo for stress and anxiety control; 3) accessibility; and 4) consumer socialization. CONCLUSIONS Findings suggest that OTC analgesic use is common among adolescents to treat pain and other non-medically-indicated conditions, such as stress and anxiety.

Abstract
OBJECTIVE Fever is one of the frequent reasons for admission to the emergency department. Studies comparing oral forms of non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol with intravenous (IV) forms for fever are common in the literature. Our study is the first emergency department study comparing IV forms of ibuprofen and paracetamol in the treatment of febrile patients. METHODS A randomized, double-blind study was conducted in a tertiary university emergency department for a six-month period. Patients aged 18-65 years who had a fever of ≥38.0 °C were included. Patients were administered 400 mg of IV ibuprofen and 1000 mg of IV paracetamol. The primary aim of the study was to determine whether there was a difference in the effect of the two drugs on fever. The secondary aim was to investigate whether there was a difference in terms of numeric rating scale (NRS) measurements and the need for additional antipyretic therapy. RESULTS A total of 200 people, 100 of whom were female, were included in the study. The mean age was 30.77 ± 10.61 years. The mean initial temperature for ibuprofen and paracetamol was 38.79 ± 0.470 °C and 38.70 ± 0.520 °C, respectively, with no difference noted between the groups (p = 0.380). It was found that both drugs significantly provided fever control in the first 30 min (p < 0.001), with no difference between them in terms of fever reduction (p = 0.980). Both drugs significantly improved in accompanying symptoms, although both drugs did not show superiority to each other (p = 0.0226). When evaluated in terms of a need for rescue medication, no significant difference was found between the two drugs (p = 0.404). No side effects were encountered during the study. CONCLUSION In adult age group patients admitted to the emergency department with high fever, the IV forms of 1000 mg paracetamol and 400 mg ibuprofen effectively and equally reduce complaints, such as fever and accompanying pain. They can be effectively used as each other's rescue medicine and as an alternative to each other in patients with comorbid diseases.

[PMID: 33605470 DOI: 10.1111/jfbc.13663] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Revised: 02/01/2021] [Accepted: 02/04/2021] [Indexed: 11/27/2022]
Abstract
This work aims to assess the anti-inflammatory effects of Tigzirt propolis native to Algeria. We divided 48 male Wistar rats into 8 groups. We orally administered ethyl acetate extract of propolis (EAP), pure polyphenols compounds, or diclofenac 5 days before induction of inflammation by of carrageenan (100 μg/ml, i.p.). We determined the development of paw edema, biological parameters, myeloperoxidase activity, TNF-α, and prostaglandin E2 and measured the oxidative status parameters, as well. Finally, we analyzed the absorption and bioaccessibility of propolis in rats' plasma using GC-MS after orally dosing rats (250 mg/kg). The pretreatment by 200 and 250 mg/kg of propolis significantly reduced the edema rates after the third hour. Propolis can restore the disruption of homeostasis as well as markers of inflammation induced by carrageenan in Wistar rats, and an increase of the enzymatic activities. Furthermore, the inflammation was better resolved in rats that received propolis than in those treated with pure polyphenols. PRACTICAL APPLICATIONS: Propolis is a natural mixture that bees produce by mixing gathered resin and gums to bee saliva and wax. Our research investigated the effect of Tigzirt propolis on the inhibition of biomarkers of inflammation and the development of paw edema. Propolis extract helped to reduce PGE2, TNF-α, myeloperoxidase, and malondialdehyde levels and increase the total antioxidant levels in plasma. Our findings emphasized the use of phenolic extract of propolis in industries such as nutraceuticals for the prevention of inflammatory diseases. It can also protect the body against damage under oxidative stress.

Abstract
Background Currently, health care systems worldwide are challenged with providing care to an increasing number of migrants, refugees, and displaced persons. In this article, we report on disease burden and drug prescription patterns in a large refugee cohort in Germany. Methods We conducted a cross-sectional study of anonymized medical records including demographic data, diagnoses, and drug prescriptions in two refugee reception centres between 2015 and 2019. Refugees and migrants received medical assistance exclusively through the on-site clinics. Thus, this study represents all medical visits of the housed residents. Results In total, n = 15531 diagnoses from n = 4858 patients in a cohort of n = 10431 accommodated refugees were recorded. N = 11898 medications were prescribed. Overall, 29.8% of all refugees sought medical attention. Half of the patients were female (49.6%), the average age was 23.8 years (SD [standard deviation] 17.0, min 0, max 81), and 41.5% were minors (<18 years). Most patients had Middle Eastern or Northern African origin (63.9%). The largest proportion of diagnoses belonged to the ICD (International Statistical Classification of Diseases and Related Health Problems) category “R” (miscellaneous, 33.5%), followed by diseases of the respiratory system (category “J”, 16.5%), or the musculoskeletal system (category “M”, 7.1%). Non-steroidal anti-inflammatory drugs were most frequently prescribed. Conclusions This analysis in two large refugee centres in Germany shows that about one third of refugees seek medical attention upon initial arrival. Complaints are manifold, with a high prevalence of respiratory infections.

Abstract
Fused diaza-heterocycles constitute the core structure of numerous bioactive natural products and effective therapeutic drugs. Among them, phthalazines have been recognized as remarkable structural leads in medicinal chemistry due to their wide application in pharmaceutical and agrochemical industries. Accessing such challenging pharmaceutical agents/drug candidates with high chemical complexity through synthetically efficient approaches remains an attractive goal in the contemporary medicinal chemistry and drug discovery arena. In this review, we focus on the recent developments in the synthetic routes towards the generation of phthalazine-based active pharmaceutical ingredients and their biological potential against various targets. The general reaction scope of these innovative and easily accessible strategies was emphasized focusing on the functional group tolerance, substrate and coupling partner compatibility/limitation, the choice of catalyst, and product diversification. These processes were also accompanied by the mechanistic insights where deemed appropriate to demonstrate meaningful information. Moreover, the rapid examination of the structure-activity relationship analyses around the phthalazine core enabled by the pharmacophore replacement/integration revealed the generation of robust, efficient, and more selective compounds with pronounced biological effects. A large variety of in silico methods and ADME profiling tools were also employed to provide a global appraisal of the pharmacokinetics profile of diaza-heterocycles. Thus, the discovery of new structural leads offers the promise of improving treatments for various tropical diseases such as tuberculosis, leishmaniasis, malaria, Chagas disease, among many others including various cancers, atherosclerosis, HIV, inflammatory, and cardiovascular diseases. We hope this review would serve as an informative collection of structurally diverse molecules enabling the generation of mature, high-quality, and innovative routes to support the drug discovery endeavors.

Abstract
The development of NSAIDs/iNOS inhibitor hybrids is a new strategy for the treatment of inflammatory diseases by suppression of the overproduction of PGE2 and NO. A novel series of aryl carboximidamides 4a-g and their cyclized 3-aryl-1,2,4-oxadiazoles 5a-g counterparts derived from indomethacin 1 were synthesized. Most of the target compounds displayed lower LPS-induced NO production IC50 in RAW 264.7 cells and potent in vitro iNOS and PGE2 inhibitory activity than indomethacin. Moreover, in carrageenan-induced rat paw oedema method, most of them exhibited higher in vivo anti-inflammatory activity than the reference drug indomethacin. Notably, 4 hrs after carrageenan injection, compound 4a proved to be the most potent anti-inflammatory agent in this study, with almost two- and eight-fold more active than the reference drugs indomethacin (1) and celecoxib, respectively. Compound 4a proved to be inhibitor to LPS-induced NO production, iNOS activity and PGE2 with IC50 of 10.70 μM, 2.31 μM, and 29 nM; respectively. Compounds 4a and 5b possessed the lowest ulcerogenic liabilities (35% and 38%, respectively) compared to 1. Histopathological analysis revealed that compounds 4a and 5b demonstrated reduced degeneration and healing of ulcers. Molecular docking studies into the catalytic binding pocket of the iNOS protein receptor (PDB ID: 1r35) showed good correlation with the obtained biological results. Parameters of Lipinski's rule of five and ADMET analysis were calculated where compound 4a had reasonable drug-likeness with acceptable physicochemical properties so it could be used as promising orally absorbed anti-inflammatory therapy and entitled to be used as future template for further investigations.

Abstract
Ibuprofen first came to market about 50 years ago and rapidly moved to over-the-counter (OTC) sales. In April 2019, the National Agency for the Safety of Medicines and Health Products (ANSM) of France issued a warning for NSAID uses by patients with infectious diseases based on an analysis of 20 years of real-world safety data on ibuprofen and ketoprofen. Nevertheless, ibuprofen remains a mainstay in the analgesic armamentarium and with numerous randomized clinical trials, head-to-head studies, and decades of clinical experience. The authors offer a review of the safety of ibuprofen and how it may differ from other NSAIDs. Ibuprofen is associated with certain well-known gastrointestinal adverse effects that are related to dose and patient population. Among nonsteroidal anti-inflammatory drugs (NSAIDs), ibuprofen has a comparatively low risk of cardiovascular adverse effects. It has been associated with renal and hepatic adverse effects, which appear to depend on dose, concomitant medications, and patient population. The association of ibuprofen with infections is more complex in that it confers risk in some situations but benefits in others, the latter in cystic fibrosis. Emerging interest in the literature is providing evidence of the role of ibuprofen as a possible endocrine disrupter as well as its potential antiproliferative effects for cancer cells. Taken altogether, ibuprofen has a favorable safety profile and is an effective analgesic for many acute and chronic pain conditions, although it-like other NSAIDs-is not without risk. After 50 years, evidence is still emerging about ibuprofen and its unique safety profile among NSAIDs. FUNDING: The Rapid Service Fee was funded by Abbott Established Pharmaceuticals Division (EPD).

Abstract
This short reply contests two assumptions made by the authors of Mayrhuber et al’s. “With fever it’s the real flu I would say.” The first is that there is influenza can be reliably defined by a medical case definition. The second is that this small qualitative study can be generalisable. However, it does underline the important point that technical diagnostic terms may be used on different registers by a variety of actors in the medical setting.

Risks Related to the Use of Non-Steroidal Anti-Inflammatory Drugs in Community-Acquired Pneumonia in Adult and Pediatric Patients. J Clin Med 2019; 8:E786. [PMID: 31163625 PMCID: PMC6617416 DOI: 10.3390/jcm8060786] [Citation(s) in RCA: 70] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2019] [Revised: 05/22/2019] [Accepted: 05/27/2019] [Indexed: 12/22/2022] Open
Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used to alleviate symptoms during community-acquired pneumonia (CAP), while neither clinical data nor guidelines encourage this use. Experimental data suggest that NSAIDs impair neutrophil intrinsic functions, their recruitment to the inflammatory site, and the resolution of inflammatory processes after acute pulmonary bacterial challenge. During CAP, numerous observational data collected in hospitalized children, hospitalized adults, and adults admitted to intensive care units (ICUs) support a strong association between pre-hospital NSAID exposure and a delayed hospital referral, a delayed administration of antibiotic therapy, and the occurrence of pleuropulmonary complications, even in the only study that has accounted for a protopathic bias. Other endpoints have been described including a longer duration of antibiotic therapy and a greater hospital length of stay. In all adult series, patients exposed to NSAIDs were younger and had fewer comorbidities. The mechanisms by which NSAID use would entail a complicated course in pneumonia still remain uncertain. The temporal hypothesis and the immunological hypothesis are the two main emerging hypotheses. Current data strongly support an association between NSAID intake during the outpatient treatment of CAP and a complicated course. This should encourage experts and scientific societies to strongly advise against the use of NSAIDs in the management of lower respiratory tract infections.

Abstract
Rhinogenic headache is frequently encountered in clinical practice. Treatment of this condition should be based on a proper evaluation of its underlying pathophysiology. Fixed-dose combinations of two or more active agents, and specifically the combination of ibuprofen plus pseudoephedrine, have been shown to be more efficacious than either monotherapy. At present, an ibuprofen/pseudoephedrine fixed-dose combination is available as an over-the-counter drug. This paper reviews in detail the pathophysiology of rhinogenic headache and discusses the rationale for treatment of this condition with a fixed-dose ibuprofen/pseudoephedrine combination.

Abstract
Paracetamol is a popular and easily available drug which is used world-wide as analgesic, antipyretic agent. Hypersensitivity reactions to this drug involve a wide range of symptoms of various importance for patient management. The EudraVigilance (EV) database serves as a system for monitoring adverse events (AE) due to drug intake. We retrospectively recorded AE reports for "paracetamol" reported from 1 January 2007 to 1 October 2018 which fulfilled the category of "serious" in EV. For further analysis the retrieved AE reports were selected according to the keywords corresponding to hypersensitivity symptoms. We included in the study 4589 AE reports with 9489 particular AEs. 24.2% of all the AE reports concerned children. The most often reported symptoms were "angioedema," "rash" and "urticaria" (each of them with a frequency of >10% in the AE reports). An important group of AEs were oedema reported as being located in the head, neck or respiratory tract. We recorded 58 AE reports with fatal outcomes, including 9 Stevens-Johnson syndrome/toxic epidermal necrolysis cases (SJS/TEN), 10 anaphylactic reactions, 21 cases of hepatic failure and a further 18 cases which occurred for other reasons. SJS/TEN, acute generalized exanthematous pustulosis and drug reaction with eosinophilia and systemic symptoms were reported 129, 42 and 25 times, respectively. Prodromes and symptoms of potentially life-threating SJS/TEN appeared in 286 of the AE reports. 380 AE reports pointed to a diagnosis of anaphylaxis. To improve patient safety, healthcare professionals, including pharmacists, can identify warning signs of severe hypersensitivity reactions to paracetamol.

Abstract
Background There is little research on laypersons’ perceptions regarding common cold and influenza, their symptomatic distinction and considerations of risk. This study investigates understanding of pathogenesis across three European countries and provides a knowledge base from which adequate prevention recommendations and treatment advice can be derived. Methods This is a qualitative research study. Semi-structured face-to-face interviews were conducted with 85 participants from three European countries (Austria n = 31, Belgium n = 30, Croatia n = 24) about their experiences, perceptions and risk considerations regarding the common cold and influenza. We performed a qualitative thematic content analysis. Results Three main themes were identified: common cold as harmless with individualistic symptoms; influenza as mainly distinguishable by fever, confinement to bed and severity of symptoms, but description about onset and duration are diverse; and views on pathogenesis contain references to disease causing agents and circumstances. Overall we found that risk perception is based largely on personal experience and risk is assumed moderate for both diseases. Conclusions Study participants possessed a fairly good understanding of symptoms, differences and pathogenesis of common cold and influenza; but explanations integrated misconceptions, such as misinterpretation of fever, disease continuums, diverse onset ideas etc. Perceptions were largely based on lived experiences and interventions for prevention and treatment should be led by health care workers and focus on these issues. Basic consultations, awareness raising activities and other knowledge disseminations strategies should include aspects of communicableness and the self-limiting nature of both diseases. An informed understanding of both infectious diseases is crucial and may also increase influenza vaccination coverage in the three respective countries effectively.

Abstract
INTRODUCTION Outpatient treatment of community-acquired pneumonia (CAP) patients with non-steroidal anti-inflammatory drugs (NSAIDs) is frequent, although this is not based on clinical recommendations and there is no scientific evidence supporting better symptom relief in comparison to acetaminophen. STATE OF THE ART Experimental data suggest that NSAIDs alter the intrinsic functions of neutrophils, limit their locoregional recruitment, alter bacterial clearance and delay the resolution of inflammatory processes during acute bacterial pulmonary challenge. In hospitalized children and adults with CAP, observational data suggest a strong and independent association between the outpatient exposure to NSAIDs and the occurrence of pleuropulmonary complications (pleural empyema, excavation, and abscess). In the only study taking into account possible protopathic bias, the association still persists. Other markers of morbidity have been described, including delay in hospital management, prolonged antibiotic therapy, and higher transfer rate to an intensive care unit. PERSPECTIVES Data describing the role of self-medication and the biological mechanisms involved are needed. CONCLUSIONS Intake of NSAIDs during outpatient treatment of CAP is probably the second modifiable factor of morbidity after inadequate antibiotic therapy. In light of existing data in children and adults, health authorities should urgently reassess the risk-benefit ratio of NSAIDS in CAP.

Abstract
The main objective of this work was to synthesize novel compounds with a benzo[de][1,2,4]triazolo[5,1-a]isoquinoline scaffold by employing (dioxo-benzo[de]isoquinolin-2-yl) thiourea as a building block. Molecular docking was conducted in the COX-2 active site to predict the plausible binding mode and rationalize the structure–activity relationship of the synthesized compounds. The structures of the synthesized compounds were confirmed by HREI-MS, and NMR spectra along with X-ray diffraction were collected for products 1 and 5. Thereafter, anti-inflammatory effect of molecules 1–20 was evaluated in vivo using carrageenan-induced paw edema method, revealing significant inhibition potency in albino rats with an activity comparable to that of the standard drugs indomethacin. Compounds 8, 9, 15 and 16 showed the highest anti-inflammatory activity. However, thermal sensitivity-hot plat test, a radiological examination and motor coordination assessment were performed to test the activity against rheumatoid arthritis. The obtained results indicate promising anti-arthritic activity for compounds 9 and 15 as significant reduction of the serum level of interleukin-1β [IL-1β], cyclooxygenase-2 [COX-2] and prostaglandin E2 [PGE2] was observed in CFA rats.

Abstract
Ibuprofen is a non-steroidal anti-inflammatory drug frequently administered to children of various ages for relief of fever and pain and is approved as an over-the-counter medication in many countries worldwide. Although there are extensive data on its efficacy and safety in children and adults, there are divergent dosing recommendations for analgesia and treatment of fever in infants, especially in the age group between 3 and 6 months of age. In this article, we have assessed the safety and efficacy of ibuprofen use in infants in an attempt to find the optimal method of pain and fever management in this specific age group. Based on the current evidence, short-term use of ibuprofen is considered safe in infants older than 3 months of age having a body weight above 5-6 kg when special attention is given to the hydration of the patient. Ibuprofen should be prescribed based on body weight using a dose of 5-10 mg/kg. This dose can be administered 3-4 times a day resulting in a maximum total daily dose of 30-40 mg/kg. The rectal route has been shown to be less reliable because of erratic absorption, especially in young infants. Since most efficacy and safety data have been derived from trials in infants with fever, future studies should focus on the efficacy of ibuprofen in young infants with pain.

Abstract
A new sensitive sensor was fabricated for simultaneous determination of codeine and acetaminophen based on 4-hydroxy-2-(triphenylphosphonio)phenolate (HTP) and multiwall carbon nanotubes paste electrode at trace levels. The sensitivity of codeine determination was deeply affected by spiking multiwall carbon nanotubes and a modifier in carbon paste. Electron transfer coefficient, α, catalytic electron rate constant, k, and the exchange current density, j 0, for oxidation of codeine at the HTP-MWCNT-CPE were calculated using cyclic voltammetry. The calibration curve was linear over the range 0.2-844.7 μM with two linear segments, and the detection limit of 0.063 μM of codeine was obtained using differential pulse voltammetry. The modified electrode was separated codeine and acetaminophen signals by differential pulse voltammetry. The modified electrode was applied for the determination of codeine and acetaminophen in biological and pharmaceutical samples with satisfactory results.

Abstract
Upper respiratory tract infections are usually self-treated with synthetic and herbal over-the-counter products. The aim of the study was to assess the reasons for the purchase of those medications in Poland. We examined 413 adults, aged 18 and over (70.5 % of them were women) using a questionnaire. The findings demonstrate that oral synthetic products were used by 76 % of respondents, while herbal products by 30 %. Synthetic products were used mainly by educated people under 65 years of age, students, and the employed. Herbal products were used mainly by older people. In conclusion, synthetic products against common cold are perceived as more effective. Such medications are used by people who probably would like to recover and return to professional activity as quickly as possible. As they generally use more medications, they are at increased risk of adverse effects resulting from drug interactions, and they should be a target group for health education programs.

Abstract
Purpose
– The misuse of pharmaceutical opioid analgesics is identified as a global public health concern. Codeine represents an interesting quandary in terms of its regulated status, with individuals varying in their metabolism of codeine, estimation of safe dosages, risk of adverse health consequences and abuse potential. Efforts to quantify and address hidden non-compliant medical codeine use, overuse and intentional misuse is compromised by availability to the public in prescribed and over the counter forms. The paper aims to discuss these issues.
Design/methodology/approach
– A review of literature on codeine use, misuse and dependence, and associated innovative medical and pharmacy interventions is presented, and was conducted as part of a larger scoping review on codeine.
Findings
– The review highlights the complexities associated with monitoring public health awareness of codeine's abuse potential, and customer/patients trends in non-compliant codeine use for therapeutic and recreational purposes. Aberrant codeine behaviours centre on visiting multiple doctors for prescriptions, repeated lost or stolen prescriptions, forging prescriptions and use of multiple pharmacies. Innovations to monitor misuse of codeine include national prescription databases and recent developments in real-time monitoring of dispensing activity.
Practical implications
– Further development of real-time monitoring processes with process evaluation is advised.
Originality/value
– This viewpoint is intended to demonstrate how efforts to quantify and address codeine use are compromised by its availability. It intends to encourage further policy and practitioner dialogue on how to monitor, support and intervene with consumers misusing codeine.

Abstract
Upper respiratory tract infection (URTI) occurs commonly in both children and adults and is a major cause of mild morbidity. It has a high cost to society, being responsible for absenteeism from school and work and unnecessary medical care, and is occasionally associated with serious sequelae. URTIs are usually caused by several families of virus; these are the rhinovirus, coronavirus, parainfluenza, respiratory syncytial virus (RSV), adenovirus, human metapneumovirus, influenza, enterovirus and the recently discovered bocavirus. This review will mainly focus on the rhinovirus, where significant advances have been made in understanding the epidemiology, natural history and relationship with other pathogens.

Abstract
BACKGROUND Many Chinese patent medicines (CPMs) have been authorized by the Chinese State of Food and Drug Administration for the treatment of the common cold. A number of clinical trials have been conducted and published. However, there is no systematic review or meta-analysis on their efficacy and safety for the common cold to justify their clinical use. METHODS We searched CENTRAL, MEDLINE, EMBASE, SinoMed, CNKI, VIP, China Important Conference Papers Database, China Dissertation Database, and online clinical trial registry websites for published and unpublished randomized clinical trials (RCTs) of CPMs for the common cold till 31 March 2013. Revman 5.2 software was used for data analysis with effect estimate presented as relative risk (RR) and mean difference (MD) with a 95% confidence interval (CI). RESULTS A total of five RCTs were identified. All of the RCTs were of high risk of bias with flawed study design and poor methodological quality. All RCTs included children aged between 6 months to 14 years. Results of individual trials showed that Shuanghuanglian oral liquid (RR 4.00; 95% CI: 2.26 to 7.08), and Xiaoer Resuqing oral liquid (RR 1.43; 95% CI: 1.15 to 1.77) had higher cure rates compared with antivirus drugs. Most of the trials did not report adverse events, and the safety of CPMs was still uncertain. CONCLUSIONS Some CPMs showed a potential positive effect for the common cold on cure rate. However, due to the poor methodology quality and the defects in the clinical design of the included RCTs, such as the lack of placebo controlled trials, the inappropriate comparison intervention and outcome measurement, the confirmative conclusions on the beneficial effect of CPMs for the common cold could not be drawn.

Abstract
RATIONALE Compared with healthy individuals, those with upper respiratory tract illnesses (URTIs) report reduced alertness and have slower reaction times. It is important to evaluate medication that can remove this behavioural malaise. OBJECTIVES The aim of this study was to compare the effects of a combination of ibuprofen plus caffeine with ibuprofen and caffeine alone, and placebo on malaise associated with URTIs, as measured by psychomotor performance and mood testing. METHODS Volunteers were randomly assigned to one of four medication conditions as follows: 200 mg ibuprofen and 100 mg caffeine; 200 mg ibuprofen; 100 mg caffeine; placebo. A single oral dose was given and testing followed for 3 h. Efficacy variables were based on the volunteers' performance, measured by psychomotor performance and mood. RESULTS The pre-drug results confirmed that those with an URTI had a more negative mood and impaired performance. Results from the simple reaction time task, at both 55- and 110-min post-dosing, showed that a single-dose of caffeinated products (I200/C100 and CAF100) led to significantly faster reaction times than IBU200 and placebo. These effects were generally confirmed with the other performance tasks. Subjective measures showed that the combination of ibuprofen and caffeine was superior to the other conditions. There were no serious adverse events reported, and study medication was well tolerated. CONCLUSIONS The results from the post-drug assessments suggest that a combination of ibuprofen and caffeine was the optimum treatment for malaise associated with URTIs in that it had significant effects on objective performance and subjective measures.

Abstract
The study investigated the efficacy and safety of a combination therapy of 1,000 mg aspirin (ASA) and 60 mg pseudoephedrine (PSE) on the symptoms of pain (combined score for headache and sore throat) and nasal congestion in 833 patients with acute upper respiratory tract viral infection (URTI), over 4 hours after a single dose in the clinic and over 3 days with multiple doses at home. The study demonstrated that over 4 hours in the clinic the combination ASA plus PSE was superior to PSE or placebo for relief of pain symptoms measured subjectively with pain scores, and was superior to ASA or placebo for relief of nasal congestion as measured objectively with rhinomanometry and subjectively with congestion scores. After 3 days of treatment, ASA plus PSE was superior to PSE but not to placebo or ASA for global pain assessments, and ASA plus PSE was superior to ASA and placebo but not to PSE for congestion assessments. No unexpected adverse events occurred and no serious adverse events were attributed to study medicines. This study demonstrates that a combination therapy of ASA plus PSE provides safe and effective relief of both common cold pain related symptoms and nasal congestion.

Abstract
BACKGROUND Teenagers in Sweden were given greater access as consumers of OTC drugs in 2009 after the reregulation of the pharmacy market, which allowed for the establishment of private pharmacies and sale of specific over-the-counter (OTC) drugs in retail stores and gas stations. Increased access to OTC drugs could provide new opportunities for self-care but attenuates the opportunity for the traditional expert surveillance of pharmacists, thus increasing the possibility of inappropriate OTC drug use. OBJECTIVES Views of 16-19 year old Swedish teenagers on OTC drugs, with special regard to analgesic drugs were explored and described, based on the following questions: How and where did they acquire their knowledge and attitudes regarding OTC drugs? What perceptions did they have about the use of OTC drugs? METHODS A qualitative approach with a descriptive design was chosen. Data were collected in 2011 with 10 focus group discussions with high school students aged 16-19 years from different parts of Sweden. A total of 77 teenagers participated, 33 males and 44 females. A manifest qualitative content analysis was performed. RESULTS While most teenagers appeared to have responsible attitudes toward OTC drugs and their use, some teenagers had attitudes that ranged from casual to careless. The focus group discussions also revealed knowledge gaps among teenagers regarding OTC drugs, and the significant influence of parents and peers on their OTC drug use. CONCLUSIONS This study provides insight into how vulnerable some teenagers could be as new consumers of OTC drugs and suggested that educational efforts could be geared toward parents as well as teenagers.

Abstract
BACKGROUND Acetaminophen is frequently prescribed for treating patients with the common cold, but there is little evidence as to whether it is effective. OBJECTIVES To determine the efficacy and safety of acetaminophen in the treatment of the common cold in adults. SEARCH METHODS We searched CENTRAL 2013, Issue 1, Ovid MEDLINE (1950 to January week 5, 2013), EMBASE (1980 to February 2013), CINAHL (1982 to February 2013) and LILACS (1985 to February 2013). SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing acetaminophen to placebo or no treatment in adults with the common cold. Studies were included if the trials used acetaminophen as one ingredient of a combination therapy. We excluded studies in which the participants had complications. Primary outcomes included subjective symptom score and duration of common cold symptoms. Secondary outcomes were overall well being, adverse events and financial costs. DATA COLLECTION AND ANALYSIS Two review authors independently screened studies for inclusion, assessed risk of bias and extracted data. We performed standard statistical analyses. MAIN RESULTS We included four RCTs involving 758 participants. We did not pool data because of heterogeneity in study designs, outcomes and time points. The studies provided sparse information about effects longer than a few hours, as three of four included studies were short trials of only four to six hours. Participants treated with acetaminophen had significant improvements in nasal obstruction in two of the four studies. One study showed that acetaminophen was superior to placebo in decreasing rhinorrhoea severity, but was not superior for treating sneezing and coughing. Acetaminophen did not improve sore throat or malaise in two of the four studies. Results were inconsistent for some symptoms. Two studies showed that headache and achiness improved more in the acetaminophen group than in the placebo group, while one study showed no difference between the acetaminophen and placebo group. None of the included studies reported the duration of common cold symptoms. Minor side effects (including gastrointestinal adverse events, dizziness, dry mouth, somnolence and increased sweating) in the acetaminophen group were reported in two of the four studies. One of them used a combination of pseudoephedrine and acetaminophen. AUTHORS' CONCLUSIONS Acetaminophen may help relieve nasal obstruction and rhinorrhoea but does not appear to improve some other cold symptoms (including sore throat, malaise, sneezing and cough). However, two of the four included studies in this review were small and allocation concealment was unclear in all four studies. The data in this review do not provide sufficient evidence to inform practice regarding the use of acetaminophen for the common cold in adults. Further large-scale, well-designed trials are needed to determine whether this intervention is beneficial in the treatment of adults with the common cold.

Abstract
The common cold, an acute upper respiratory tract infection of viral origin, is among the most widespread ailments in the world. Although the general public usually relies on over-the-counter (OTC) medication(s) to treat cough/cold symptoms, reliable guidance is needed to help select the appropriate OTC medication for each individual. Consumers may be confused by the wide variety of products available, containing ≥ 1 active pharmaceutical ingredient. Health care professionals are in a position to help people identify the most bothersome symptom(s), evaluate underlying medical conditions and medications, and recommend the most appropriate OTC active ingredient(s) for treatment. Patients should be educated about available OTC medications to manage cough/cold symptoms and the importance of learning to read the package labeling for appropriate dosing and administration. In addition, potentially serious causes of cough/cold symptoms (eg, influenza, asthma, bronchitis) or underlying medical conditions that put the individual at increased risk for complications should be ruled out when symptoms do not resolve within a typical cold timeline. This review article discusses the active ingredients found in OTC medications and the clinical evidence supporting their use. The need to educate health care professionals and patients on the safe and effective use of OTC medications is addressed, and we offer a guide for the management of symptoms that appear during the timeline of a typical common cold.

Abstract
BACKGROUND Sore throat is a common condition associated with acute upper respiratory tract infection, and recurrent episodes of infection may result in chronic tonsillitis. The current UK and USA guidelines for tonsillectomy use the incidence of sore throat episodes as an indication for surgery. However, the mechanism of sore throat is poorly described in the literature. OBJECTIVES This review will provide basic information for the clinician regarding: the causes, pathophysiology and neurophysiology of sore throat; the mechanism of inflammation; and the role of transient receptor potential ion channels as nociceptors involved in sore throat. The review will present new ideas on the mechanism of ice therapy as an analgesic for post-tonsillectomy pain, and the role of vanilloid and cold receptors.

Abstract
Background Common cold is caused by a variety of respiratory viruses. The prevalence in children is high, and it potentially contributes to significant morbidity. Iota-carragenan, a polymer derived from red seaweed, has reduced viral load in nasal secretions and alleviated symptoms in adults with common cold. Methods We have assessed the antiviral and therapeutic activity of a nasal spray containing iota-carrageenan in children with acute symptoms of common cold. A cohort of 153 children between 1–18 years (mean age 5 years), displaying acute symptoms of common cold were randomly assigned to treatment with a nasal spray containing iota-carrageenan (0.12%) as verum or 0.9% sodium chloride solution as placebo for seven days. Symptoms of common cold were recorded and the viral load of respiratory viruses in nasal secretions was determined at two consecutive visits. Results The results of the present study showed no significant difference between the iota carrageenan and the placebo group on the mean of TSS between study days 2–7. Secondary endpoints, such as reduced time to clearance of disease (7.6 vs 9.4 days; p = 0.038), reduction of viral load (p = 0.026), and lower incidence of secondary infections with other respiratory viruses (p = 0.046) indicated beneficial effects of iota-carrageenan in this population. The treatment was safe and well tolerated, with less side effects observed in the verum group compared to placebo. Conclusion In this study iota-carrageenan did not alleviate symptoms in children with acute symptoms of common cold, but significantly reduced viral load in nasal secretions that may have important implications for future studies.

Abstract
BACKGROUND Although combination formulas containing antihistamines, decongestants and/or analgesics are sold over-the-counter (OTC) in large quantities for the common cold, the evidence of effectiveness is limited. OBJECTIVES To assess the effectiveness of antihistamine-decongestant-analgesic combinations in reducing the duration and alleviating the symptoms of the common cold in adults and children. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 4), which contains the Cochrane Acute Respiratory Infections Group's Specialised Register, OLDMEDLINE (1953 to 1965), MEDLINE (1966 to November Week 3, 2011) and EMBASE (1990 to December 2011). SELECTION CRITERIA Randomised controlled trials (RCTs) investigating the effectiveness of antihistamine-decongestant-analgesic combinations compared with placebo, other active treatment (excluding antibiotics) or no treatment in children and adults with the common cold. DATA COLLECTION AND ANALYSIS Two review authors independently extracted and summarised data on general recovery, nasal obstruction, rhinorrhoea, sneezing, cough and side effects. We categorised the trials according to the active ingredients. MAIN RESULTS We included 27 trials (5117 participants) of common cold treatments. Fourteen trials studied antihistamine-decongestant combinations; two antihistamine-analgesic; six analgesic-decongestant; and five antihistamine-analgesic-decongestant combinations. In 21 trials the control intervention was placebo and in six trials an active substance. Reporting of methods in most trials was poor and there were large differences in design, participants, interventions and outcomes. Pooling was only possible for a limited number of studies and outcomes.Antihistamine-decongestant: 12 trials. Eight trials report on global effectiveness, six could be pooled; n = 309 on active treatment, n = 312 placebo) the odds ratio (OR) of treatment failure was 0.27 (95% confidence interval (CI) 0.15 to 0.50); the number needed to treat for an additional beneficial outcome (NNTB) was four (95% CI 3 to 5.6). On the final evaluation day 41% of participants in the placebo group had a favourable response compared to 66% on active treatment. Of the two trials that were not included in the pooling, one showed some global effect, the other showed no effect.Antihistamine-analgesic: three trials. Two reported on global effectiveness, data from one study was presented. (n = 290 on active treatment, n = 292 ascorbic acid). The OR of treatment failure was 0.33 (95% CI 0.23 to 0.46) and the NNTB was 6.67 (95% CI 4.76 to 12.5). After six days of treatment 43% were cured in the control group and 70% in the active treatment group. The second study also showed an effect in favour of active treatment.Analgesic-decongestant: six trials. One trial reported on global effectiveness: 73% benefited compared with 52% in the control group (paracetamol) (OR 0.28, 95% CI 0.15 to 0.52).Antihistamine-analgesic-decongestant: Five trials. Four trials reported on global effectiveness, two could be pooled: global effect reported (less than one severity point on a four or five-point scale) with active treatment (52%) and placebo (34%); the OR of treatment failure was 0.47 (95% CI 0.33 to 0.67) and the NNTB was 5.6 (95% CI 3.8 to 10.2). Two other trials found no beneficial effect. Two other studies did not show any effect.Two studies with antihistamine-decongestant (113 children) could not be pooled. There was no significant effect of the active treatment.Adverse effects: the combination of antihistamine-decongestant had more adverse effects than the control intervention but the difference was not significant: 157/810 (19%) versus 60/477 (13%) participants suffered one or more adverse effects (OR 1.58, 95% CI 0.78 to 3.21). Analgesic-decongestant combinations had significantly more adverse effects than control (OR 1.71, 95% CI 1.23 to 2.37); the number needed to treat for an additional harmful outcome (NNTH) was 14. None of the other two combinations caused significantly more adverse effects. Antihistamine-analgesic: 11/90 with combination suffered one or more adverse effects (12%) versus 9/91 (10%) with control (OR 1.27, 95% CI 0.50 to 3.23). Antihistamine-analgesic-decongestant: in one study 5/224 (2%) suffered adverse effects with active treatment versus 9/208 (4%) with placebo. Two other trials reported no differences between treatment groups but numbers were not reported. AUTHORS' CONCLUSIONS Current evidence suggests that antihistamine-analgesic-decongestant combinations have some general benefit in adults and older children. These benefits must be weighed against the risk of adverse effects. There is no evidence of effectiveness in young children.

Abstract
BACKGROUND Exposure to over-the-counter (OTC) ibuprofen and other OTC non-steroidal anti-inflammatory drugs (NSAIDs) is substantial. Although the literature on gastrointestinal (GI) safety of NSAID therapy is extensive, the risk profiles of OTC and prescription dosing are seldom separated, and few studies provide risks specific to OTC ibuprofen. OBJECTIVE To conduct a literature review to evaluate the risk of GI bleeding events related to OTC ibuprofen use. METHODS Published clinical trials, observational studies, and meta-analyses of OTC ibuprofen use, defined as up to 1200 mg/day or stated as 'over the counter,' reporting endpoints of incidence rates and proportions of GI bleeding events (e.g., GI bleeding-related hospitalizations and deaths) were identified via MEDLINE through 2010. Data from these studies were summarized. RESULTS Twenty studies (nine observational, ten clinical trials, one meta-analysis) reporting incidence rates and proportions of a GI bleeding-related event associated with OTC or OTC-specific doses of ibuprofen were included. The frequency of a GI-related hospitalization was <0.2% for patients on OTC-comparable doses. Incidence rates among those using OTC-comparable doses ranged from 0 to 3.19 per 1000 patient-years. The incidence of a GI bleeding-related event increased with age and the use of concomitant medications, and there was a general, though not always statistically significant, ibuprofen dose-response relationship. The relative risk of any GI bleeding-related event ranged from 1.1 to 2.4 for users of OTC-specific doses of ibuprofen compared to non-users. CONCLUSIONS Studies reported low incidence of GI bleeding events with use of OTC ibuprofen. Few published studies that specifically investigated OTC ibuprofen use were identified. Varying methodologies and definitions of exposure and outcomes prevented direct comparison of many results. Only studies that used the methods herein described were identified. Further research evaluating the risk of GI bleeding events in patients taking OTC-specific ibuprofen use may be useful.

Abstract
WHAT IS KNOWN AND OBJECTIVE Analgesics are among the most widely used drugs and there is wide intercountry variability in the rates of consumption of different analgesics. Our objective is to determine and compare patterns of analgesic consumption in the Slovak Republic and a number of other European countries. METHODS We undertook a drug utilization study using WHO ATC/defined daily doses (DDD) methodology. Wholesale analgesic data collected by the Slovak State Institute for Drug Control were used. Utilization was calculated as DDD per 1000 inhabitants per day. Comparison with wholesale data from Czech Republic, Estonia, Finland, Norway and Denmark, published on the Internet, was made. RESULTS AND DISCUSSION Paracetamol/acetaminophen consumption varied only a little in Slovak Republic and Czech Republic, whereas consumption in Nordic countries was significantly higher (P < 0.05) and in Estonia significantly lower. Ibuprofen consumption was significantly higher in Czech Republic and Finland. Significantly lower consumption was in Norway. The lowest consumption of ASA/aspirin was in Denmark and in Norway. The highest consumption was in Finland. WHAT IS NEW AND CONCLUSION Effective therapy needs good prescribing and well-informed prescribers and patients. Our study highlights wide differences in analgesic consumption even among similar European countries. The basis of these differences and their potential clinical impact require further investigation.
