Abstract
CONTEXT Desloratadine, an H1 receptor antagonist, is suggested as an effective first-line drug for chronic urticarial (CU). However, the efficacy of desloratadine alone is limited, and the recurrence rate of CU is relatively high. OBJECTIVE We sought to evaluate the efficacy and clinical feasibility of desloratadine in combination with compound glycyrrhizin in the treatment of CU. MATERIALS AND METHODS A systematic literature search was conducted in the databases of the China National Knowledge Infrastructure Database, VIP, WanFang, PubMed, and Web of Science using subject terms: "Chronic urticaria", "Loratadine", and "Compound glycyrrhizin". Randomised controlled trials (RCTs) that compared the efficiency and safety of the combination treatment with desloratadine alone starting from January 1, 2014 until February 10, 2021 were selected by two co-first authors independently, and the extracted data were analysed using Rev Man 5.3 software. RESULTS Fourteen RCTs were included in our meta-analysis with a total of 1501 patients. The results showed that the combination treatment yielded a better treatment effect (total response rate: RR = 1.23, 95% CI: 1.17 to 1.29, p < 0.00001; cure rate: RR = 1.50, 95% CI: 1.30 to 1.73, p < 0.00001), lower recurrence rate as well as superior immune improvement than the treatment with desloratadine alone. In addition, there was no significant difference in the safety of the two treatments. DISCUSSION AND CONCLUSION The combination of desloratadine and compound glycyrrhizin is a promising treatment for CU and is associated with decreased serum IgE level and improved proportions of CD4+ T and CD8+ T cells.

Abstract
PURPOSE The work aimed to develop a co-loaded loratadine and sulpiride nasal nanoemulsion for allergic rhinitis management. METHODS Compatibility studies were conducted adopting differential scanning calorimetry and Fourier transform infrared spectroscopy. Nanoemulsion formulations were prepared using soybean lecithin, olive oil and tween 80. Sodium cholate and glycerol were employed as co-surfactants. Nanoemulsions were assessed for viscosity, pH, droplet size, polydispersity index, zeta potential, electrical conductivity, entrapment, In vitro drug release and corresponding kinetics. Stability of the selected formulation was investigated. The biological effectiveness was evaluated in rabbit models of ovalbumin-induced allergic rhinitis by measuring TNF-α, TGF-β and IL-1. RESULTS Compatibility studies revealed absence of drug/drug interactions. Nanoemulsions exhibited > 90% entrapment efficiency. The selected nanoemulsion demonstrated small droplet size (85.2 ± 0.2 nm), low PDI (0.35 ± 0.0) and appropriate Zeta Potential (-23.3 ± 0.2) and stability. It also displayed enhanced in vitro drug release following the Higuashi Diffusion and Baker-Lonsdale models. The mean relative mRNA expression of TNF-α, IL-1 and TGF-β significantly decreased from 9.59 ± 1.06, 4.15 ± 0.02 and 4.15 ± 0.02 to 1.28 ± 0.02, 1.93 ± 0.06 and 1.56 ± 0.02 respectively after treatment with the selected nanoemulsion formulation. CONCLUSION The results reflected a promising potent effect of the combined loratadine and sulpiride nasal nanoemulsion in managing the symptoms of allergic rhinitis.

Abstract
Some histamine H1 receptor (H1R) antagonists induce adverse sedative reactions caused by blockade of histamine transmission in the brain. Desloratadine is a second-generation antihistamine for treatment of allergic disorders. Its binding to brain H1Rs, which is the basis of sedative property of antihistamines, has not been examined previously in the human brain by positron emission tomography (PET). We examined brain H1R binding potential ratio (BPR), H1R occupancy (H1RO), and subjective sleepiness after oral desloratadine administration in comparison to loratadine. Eight healthy male volunteers underwent PET imaging with [11C]-doxepin, a PET tracer for H1Rs, after a single oral administration of desloratadine (5 mg), loratadine (10 mg), or placebo in a double-blind crossover study. BPR and H1RO in the cerebral cortex were calculated, and plasma concentrations of loratadine and desloratadine were measured. Subjective sleepiness was quantified by the Line Analogue Rating Scale (LARS) and the Stanford Sleepiness Scale (SSS). BPR was significantly lower after loratadine administration than after placebo (0.504 ± 0.074 vs 0.584 ± 0.059 [mean ± SD], P < 0.05), but BPR after desloratadine administration was not significantly different from BPR after placebo (0.546 ± 0.084 vs 0.584 ± 0.059, P = 0.250). The plasma concentration of loratadine was negatively correlated with BPR in subjects receiving loratadine, but that of desloratadine was not correlated with BPR. Brain H1ROs after desloratadine and loratadine administration were 6.47 ± 10.5% and 13.8 ± 7.00%, respectively (P = 0.103). Subjective sleepiness did not significantly differ among subjects receiving the two antihistamines and placebo. At therapeutic doses, desloratadine did not bind significantly to brain H1Rs and did not induce any significant sedation.

Abstract
Background The aim of this study was to compare the effect of antileukotriene (anti-LT), antihistamine, and a combination of anti-LT and antihistamine on the symptoms and nasal resistance in allergic rhinitis patients. Methods We performed a placebo-controlled study, with 120 persistent, moderate to severe allergic rhinitis patients randomly selected to receive the different treatments for 4 weeks: no treatment, 10 mg of cetirizine once per day, 20 mg of zafirlukast once per day, 20 mg of zafirlukast twice per day, a combination of 20 mg of zafirlukast and 10 mg of cetirizine once per day, or a combination of 20 mg of zafirlukast twice per day and 10 mg cetirizine once per day. The nasal secretion nitric oxide (NO) concentration, nasal symptom score, and nasal resistance were measured before and after treatment. Results Total symptom scores improved in each treated group compared with the control group (p < 0.05). Nasal obstruction significantly improved in the anti-LT-treated groups (p < 0.05). High-dose anti-LT or the combination of low-dose anti-LT and antihistamine significantly improved allergy symptoms compared with no treatment, low-dose anti-LT, or antihistamine alone (p < 0.05). Furthermore, anti-LT decreased NO concentration in nasal secretions (p < 0.05), regardless of the dose administered. Conclusion These results suggest that high-dose anti-LT alone or the combination of low-dose anti-LY and antihistamine can effectively treat allergic rhinitis.

Abstract
STUDY OBJECTIVE We evaluate the efficacy of a 4-day course of prednisone added to antihistamine for the management of acute urticaria in an emergency department (ED). METHODS In this double-blind randomized clinical trial, patients were eligible for inclusion if aged 18 years or older and with acute urticaria of no more than 24 hours' duration. Patients with anaphylaxis or who had received antihistamines or glucocorticoids during the previous 5 days were not included. In addition to levocetirizine (5 mg orally for 5 days), patients were assigned to receive prednisone (40 mg orally for 4 days) or placebo. The primary endpoint of the study was itching relief 2 days after the ED visit, rated on a numeric scale of 0 to 10. Secondary endpoints were rash resolution, relapses, and adverse events. RESULTS A total of 100 patients were included, 50 in each group. Seven patients in the prednisone group and 8 in the placebo group discontinued treatment. At 2-day follow-up, 62% of patients in the prednisone group had an itch score of 0 versus 76% of those in the placebo group (Δ 14%; 95% confidence interval -31% to 4%). Thirty percent of patients in the prednisone group and 24% in the placebo group reported relapses (Δ 6%; 95% confidence interval -23% to 11%). Mild adverse events were reported by 12% of patients in the prednisone group and 14% in the placebo group. CONCLUSION The addition of a prednisone burst did not improve the symptomatic and clinical response of acute urticaria to levocetirizine. This study does not support the addition of corticosteroid to H1 antihistamine as first-line treatment of acute urticaria without angioedema.

Abstract
BACKGROUND AND OBJECTIVES Bilastine is a novel second-generation antihistamine for the symptomatic treatment of allergic rhinitis and urticaria. The objective of this study was to evaluate the pharmacokinetics, pharmacodynamics, and tolerability of bilastine following single and multiple oral doses in healthy Japanese subjects. The pharmacokinetic and pharmacodynamic profiles were compared with those reported in Caucasian subjects. METHODS In a single-blind, randomized, placebo-controlled, parallel-group, single- and multiple-ascending dose study, bilastine tablets were administered at single doses of 10, 20, and 50 mg (Part I), and once daily for 14 days at 20 and 50 mg (Part II). RESULTS After single oral doses, maximum plasma concentrations (C max) were reached at 1.0-1.5 h postdose. Plasma exposure [C max and area under the plasma concentration-time curve (AUC)] increased dose-proportionally at single doses of 10-50 mg. In repeated-dose administration, no remarkable differences were observed between Day 1 and Day 14 for C max or AUC. For inhibitory effects on wheal and flare response, bilastine 20 and 50 mg showed significant inhibition from 1.5 h after administration as compared with placebo, and the significant effect persisted for 24 h after administration. The rates of adverse events (AEs) were comparable between bilastine and placebo in both Part I and Part II. In addition, no dose- or administration period-dependent tendency of increase in rate of AEs or worsening of severity was observed. CONCLUSION Bilastine exhibits similar single- and multiple-dose pharmacokinetic and pharmacodynamic characteristics in healthy Japanese subjects compared with those observed in Caucasian subjects in previous studies.

Abstract
Introduction A combination of antihistamines and oral corticosteroids is often used to treat acute symptoms of allergic rhinitis. Objective To evaluate safety and efficacy of desloratadine plus prednisolone in the treatment of acute symptoms of children (2–12 years) with allergic rhinitis, and to compare it to dexchlorpheniramine plus betamethasone. Methods Children with moderate/severe persistent allergic rhinitis and symptomatic (nasal symptoms score [0–12] ≥ 6) were allocated in a double-blind, randomized fashion to receive dexchlorpheniramine plus betamethasone (n = 105; three daily doses) or desloratadine plus prednisolone (n = 105; single dose followed by two of placebo) for 7 days. At the beginning and end of the evaluation, the following were obtained: nasal symptoms score, extra nasal symptoms score, peak nasal inspiratory flow, blood biochemistry, and electrocardiogram. Ninety-six children of the dexchlorpheniramine plus betamethasone group and 98 of the desloratadine plus prednisolone group completed the protocol. Results The two groups were similar regarding initial and final nasal symptoms scores, extra nasal symptoms scores and peak nasal inspiratory flow. A drop of 76.4% and 79.1% for nasal symptoms score, 86.0% and 79.2% for extra nasal symptoms score, as well as an increase of 25.2% and 24.3% for peak nasal inspiratory flow occurred for those treated with desloratadine plus prednisolone and dexchlorpheniramine plus betamethasone, respectively. There were no significant changes in blood chemistry. Sinus tachycardia was the most frequent electrocardiogram change, but with no clinical significance. Drowsiness was reported significantly more often among those of dexchlorpheniramine plus betamethasone group (17.14% × 8.57%, respectively). Conclusion The desloratadine plus prednisolone combination was able to effectively control acute symptoms of rhinitis in children, improving symptoms and nasal function. Compared to the dexchlorpheniramine plus betamethasone combination, it showed similar clinical action, but with a lower incidence of adverse events and higher dosing convenience.

Abstract
Objectives: The association between adenoidal hypertrophy and rhinosinusitis with upper airway inflammation is increasingly recognized; however, no study has used magnetic resonance imaging (MRI) to assess the changes in adenoid size after medical treatment of rhinosinusitis. Methods: Thirteen children referred to a tertiary allergy clinic with symptoms of rhinosinusitis received medical treatment over a 4-month period. All underwent MRI before and after treatment. The medical treatment regimen comprised a short course of oral antibiotics and oral steroids and a longer course of oral antihistamines and intranasal steroids. Results: The pretreatment MRI demonstrated enlarged adenoids and rhinosinusitis in all 13 children, with evidence of extensive rhinosinusitis in 9 of the 13. The treatment resulted in an improvement in overall symptom score; the most significant improvement was seen in mouth breathing. The posttreatment MRI showed a statistically significant reduction in adenoid size and adenoid/nasopharynx ratio, which was associated with a significant decrease in sinus involvement on MRI. Conclusions: There is a high association between adenoidal hypertrophy and rhinosinusitis in the context of an allergy clinic. Magnetic resonance imaging can document the changes in adenoid size associated with resolution of rhinosinusitis. Further studies are necessary to validate these pilot data and further assess the effects of medical treatment and the role of MRI in adenoidal hypertrophy.

Abstract
The aim of this study was to develop orally disintegrated tablets (ODT) with loratadine using Parteck ODT and Ludiflash--new commercially available tableting excipients based on co-processed mannitol. ODT containing loratadine were prepared with 3% addition of various superdisintegrants (AcDiSol, Kollidon CL-F and Kollidon CL-SF) by direct compression method. Obtained tablets were characterized for friability, pore structure, and wetting and disintegration time measured by four independents methods. In order to identify possible interactions between loratadine and the excipients, differential scanning calorimetry was used. The results showed that all formulated ODT were characterized by appropriate mechanical properties (friability < 1%), the uniform content of the drug substance and pleasant mouth feeling. Disintegration time below 30 s was observed in formulations with crospovidones as disintegrant.

Abstract
Chronic cold urticaria (ColdU) is a rare disease characterized by mast cell-mediated wheals and angioedema following cold exposure. Second-generation H1-antihistamines, such as rupatadine, are the recommended first-line therapy. As of yet, the effects of rupatadine up-dosing on development of ColdU symptom have only been partially characterized. Two-centre, randomized, double-blind, 3-way crossover, placebo-controlled study in patients with a confirmed ColdU was designed to assess the effects of up-dosing of rupatadine. A total of 23 patients were randomized to receive placebo, rupatadine 20 mg/day, and rupatadine 40 mg/day for 1 week. The primary outcome was change in critical temperature thresholds and critical stimulation time thresholds after treatment. Secondary endpoints included assessment of safety and tolerability of rupatadine. Both 20 and 40 mg rupatadine were highly effective in reducing critical temperature thresholds (p < 0.001) and critical stimulation time thresholds (p < 0.001). In conclusion, rupatadine 20 and 40 mg significantly reduced the development of chronic cold urticaria symptom without an increase in adverse effects.

Abstract
BACKGROUND A new, simple and accurate stability-indicating reverse phase high performance liquid chromatography method was developed and validated during the early stage of drug development of an oral lyophilizate dosage form of cetirizine dihydrochloride. METHODS For RP-HPLC analysis it was used an Eclipse XDB C8 column 150 mm × 4.6 mm, 5 μm (Agilent columns, Barcelona, Spain) as the stationary phase with a mobile phase consisted of a mixture of 0.2 M K2HPO4 pH 7.00 and acetonitrile (65:35, v/v) at a flow rate of 1 mL min (-1). Detection was performed at 230 nm using diode array detector. The method was validated in accordance with ICH guidelines with respect to linearity, accuracy, precision, specificity, limit of detection and quantification. RESULTS The method results in excellent separation between the drug substance and its stress-induced degradation products. The peak purity factor is >950 for the drug substance after all types of stress, which confirms the complete separation of the drug substance peak from its stress induced degradation products. Regression analysis showed r(2) > 0.999 for cetirizine dihydrochloride in the concentration range of 650 μg mL (-1) to 350 μg mL(-1) for drug substance assay and a r(2) > 0.999 in the concentration range of 0.25 μg mL(-1) to 5 μg mL(-1) for degradation products. The method presents a limit of detection of 0.056 μg mL (-1) and a limit of quantification of 0.25 μg mL(-1). The obtained results for precision and accuracy for drug substance and degradation products are within the specifications established for the validation of the method. CONCLUSIONS The proposed stability-indicating method developed in the early phase of drug development proved to be a simple, sensitive, accurate, precise, reproducible and therefore useful for the following stages of the cetirizine dihydrochloride oral lyophilizate dosage form development.

Abstract
The aim of this study was to evaluate the possible favorable effect of desloratadine-montelukast combination on salivary glands (SG) function in patients with allergic rhinitis (AR) using SG scintigraphy. The study population consisted of 64 patients with AR and 28 healthy controls: 14 males and 14 females, with mean age 32.3±8.6 years. The patients were divided into two groups: the untreated patients group of 32 patients, 16 males and 16 females, mean age 28.5±5.4 years and the treated group, who received the standard clinically recommended oral dose of montelukast 10mg/d and desloratadine 5mg/d for 6 weeks. This group consisted of 32 patients, 16 males and 16 females, mean age 38.3±8.4 years. All patients and healthy controls underwent SG scintigraphy. After the intravenous injection of technetium-99m pertechnetate, ((99m)Tc-P), dynamic SG scintigraphy was performed for 25min. Using the time-activity curves, the following glandular function parameters were calculated for the parotid and the submandibular SG: uptake ratio, maximum accumulation and ejection fraction. Results showed SG hypofunction. All functional parameters obtained for the untreated patients and for the desloratadine-montelukast treated patients were significantly lower than those in healthy controls (P<0.05). There was no statistically significant difference between treated and untreated patients (P>0.05). In conclusion, our study showed that hypofunction of SG was present in all patients with AR. This hypofunction, as tested by semi-quantitative SG scintigraphy, and also the quality of life did not improve after treatment with montelukast and desloratadine.

Abstract
CONCLUSION This study demonstrated that treatment with montelukast in combination with levocetirizine may have a beneficial effect on clinical improvement of middle ear fluid in children with otitis media with effusion (OME). OBJECTIVE To evaluate the effect of the combination of montelukast and levocetirizine on shortening the duration of effusion in successfully treated OME in children. METHODS This was a randomized, prospective, double-blind, placebo-controlled trial. The study group consisted of 120 children (age range 2-6 years), who were diagnosed with OME of at least 2 months duration. The children were randomized into one of four groups. The treatment packs containing montelukast 4 mg (tablet) and/or levocetirizine 2.5 mg/5 ml as the active drug or placebo were prepared, numbered, and distributed by the second author. RESULTS The amelioration of bilateral otoscopic sign scores in the combination therapy group was statistically significantly greater than in all the other groups (p < 0.05). Improvement in bilateral tympanometric findings in the combination therapy group and montelukast group was greater than in the other groups. However, this difference was not statistically significant (p > 0.05). When we compared the difference between otoscopic sign scores before and after treatment we found that it was statistically significant in every group (p > 0.05). However, the significant improvement in tympanometric findings occurred in all groups except the levocetirizine group (p > 0.05).

Abstract
Chronic urticaria is a distressing disease that affects up to 1 % of the general population at a time point in life and may severely worsen the quality of life. First-line treatment has been based on antihistamines, and presently relies on the use of non-sedating, second-generation antihistamines; following the recommendations of the recent international guidelines, in patients who do not respond to antihistamines at licensed doses, the daily dosage of these drugs can be increased up to fourfold. Nonetheless, a significant proportion of patients with chronic urticaria remain poorly controlled; in these cases, alternative therapeutic approaches have to be considered. This article critically reviews all of the third- and fourth-line treatment options suggested for patients whose disease is refractory to antihistamines, including systemic corticosteroids, leukotriene receptor antagonists, several different anti-inflammatory drugs (dapsone, sulfasalazine, hydroxychloroquine), various immunosuppressive drugs (calcineurin inhibitors, methotrexate, cyclophosphamide, azathioprine, mycophenolate mofetil), intravenous immunoglobulin, and newer treatment options, such as omalizumab and other biologic drugs. In addition, the article examines possible future treatment options based on recent findings about pathogenic mechanisms, and considers the treatment of antihistamine-unresponsive urticaria in special conditions such as children and pregnancy/lactation. The evidence supporting the use of several of the discussed drugs is presently limited and thus insufficient to recommend their routine use; as a consequence, such compounds should be considered only in specific cases and in adequate settings.

Abstract
BACKGROUND There are few reports on the effects of intranasal Botulinum Toxin-A (BTX-A) as a treatment of allergic rhinitis (AR). In this study, we compared the efficacy of intranasal BTX-A to cetirizine in the treatment of AR. METHODS Fifty AR patients at the age of 26.2 ± 9.1 years (64% females), were recruited to the trial according to the Allergic Rhinitis and its Impact on Asthma (ARIA) criteria. Participants randomly received either intranasal injection of BTX-A (75IU Dysport®) or cetirizine (10mg/day). Symptoms (based on the ARIA) and side effects were assessed every two weeks for two months. Quality of life was evaluated before and after the study using the Rhinasthma questionnaire. RESULTS Total symptom severity score of patients significantly decreased (P < 0.001) and quality of life significantly improved (P < 0.001) at the same level in both groups. Side effects included nasal dryness (4%) and epistaxis (4%) in the BTX-A group. In the cetirizine group 44% sleepiness and 4% blurred vision was reported. CONCLUSIONS Nasal injection of BTX-A shows the same therapeutic effects as cetirizine in the management of AR. Since BTX is expensive, we do not suggest it in the first line of treatment for AR. However, BTX-A is a potential treatment for patients who are resistant or not compliant to the routine medications of AR. Further studies are required to investigate implications and limitations of BTX-A in the treatment of AR.

Abstract
BACKGROUND Allergic rhinitis represents a worldwide health problem. The prevalence is increasing. The aim of this study was to analyse the correlation between the severity of allergic rhinitis and an adequate treatment dose of modern oral antihistamines. METHODS From a comprehensive databank containing data from ten different open-label prospective observational studies including raw data of 140,853 patients with allergic rhinitis, symptomatology variables were analysed and scored to study the effects of treatment with four antihistamines (Desloratadine, Ebastine, Fexofenadine, Levocetirizine) alone or in combination with intranasal corticosteroids. The patient data were collected in 23,606 study centres from Germany, mostly medical specialist and some primary care physicians in private practice. The analyses were performed via individual patient data meta-analysis techniques. RESULTS Finally 92,900 patient data from nine of ten studies could be analysed. One study with data of 47,953 patients was excluded due to incomplete treatment documentation. Both monotherapy analysis subgroups (Total Symptom Score and Total Nasal Symptom Score) were significantly better than those of their combinations with intranasal steroids. Monotherapy with levocetirizine was determined to be significantly more effective in lowering the Total Symptom Score (p < 0.001) and the Total Nasal Symptom Score (p < 0.05) than the other antihistamines. In the next stage, a greater positive effect of levocetirizine was demonstrated in relation to the severity of the clinical symptoms of allergic rhinitis (Total Nasal Symptom Score in cases with severe symptomatology [effect size = -0.09]). CONCLUSIONS Levocetirizine asserted itself as the only antihistamine compared with the others as significant in this analysis. The study authors recommend monotherapy with the new-generation antihistamine levocetirizine, especially in severe cases of allergic rhinitis.

Abstract
Non-sedating H1-antihistamines are the recommended first-line treatment for chronic spontaneous urticaria. While efficacy studies usually apply continuous daily treatment regimens, many patients take their medication on demand. In this randomized, double-blind trial we tested whether on-demand H1-antihistamine desloratadine in standard and higher doses is able to improve the resolution of existing wheals. Symptoms of 29 patients with chronic spontaneous urticaria were followed without treatment on one day and again on another day during the next 3 weeks after a single dose of either 5 mg or 20 mg desloratadine, using different objective measures. While the intervention with both doses of desloratadine was effective in terms of a reduction in hyperthermic skin area, there was no improvement in wheal area and wheal volume compared with no treatment. Wheal numbers were reduced after treatment with 20 mg, but not 5 mg, desloratadine. In conclusion, the beneficial effects of non-sedating H1-anti-histamines given on demand appear to be low. Thus, a preventive treatment strategy should be preferred in chronic spontaneous urticaria.

Abstract
Desloratadine, a nonsedating histamine H(1)-receptor antagonist, is metabolized to 3-hydroxy (3-OH) desloratadine. Impaired hepatic function could result in increased exposure to desloratadine. This study assessed possible differences in the pharmacokinetics and safety of desloratadine and 3-OH desloratadine in subjects (N = 21) with moderate hepatic dysfunction or normal liver function. Subjects were given desloratadine 5 mg once daily for 10 days and were assessed in several pharmacokinetic parameters. A similar degree of plasma protein binding to desloratadine and 3-OH desloratadine was observed in healthy volunteers and subjects with moderate hepatic impairment. All subjects with hepatic impairment were normal metabolizers. Three subjects with normal liver function, all African American, were identified as poor metabolizers. Exposure to desloratadine in the poor metabolizers was 2.6- to 6.5-fold greater than in other subjects with normal liver function. Eleven treatment-related adverse events, all mild to moderate in severity, were reported. Results suggest that subjects with moderate hepatic impairment experienced a greater increase in desloratadine exposure than subjects with normal liver function. Poor metabolizers had more exposure to desloratadine than normal metabolizers with or without hepatic impairment. Desloratadine administered at a daily dose of 5 mg was well tolerated.

Abstract
Nonsedating antihistamines are the first-choice treatment for all forms of urticaria. In patients with recalcitrant urticaria who do not respond to conventional doses of antihistamines, current guidelines recommend increasing doses by up to 4 times in order to obtain better control of the disease. Although few studies have been conducted, there are convincing data from controlled trials for cetirizine, levocetirizine, and desloratadine that support the use of increased doses of such drugs in unresponsive patients. The use of higher doses of antihistamines has not been associated with increased adverse effects or somnolence. More studies with other second-generation antihistamines are required in order to improve the treatment of patients with severe, recalcitrant urticaria.

Abstract
Bilastine is a new H1 antagonist with no sedative side effects, no cardiotoxic effects, and no hepatic metabolism. In addition, bilastine has proved to be effective for the symptomatic treatment of allergic rhinoconjunctivitis and urticaria. Pharmacological studies have shown that bilastine is highly selective for the H1 receptor in both in vivo and in vitro studies, and with no apparent affinity for other receptors. The absorption of bilastine is fast, linear and dose-proportional; it appears to be safe and well tolerated at all doses levels in healthy population. Multiple administration of bilastine has confirmed the linearity of the kinetic parameters. The distribution in the brain is undetectable. The safety profile in terms of adverse effects is very similar to placebo in all Phase I, II and III clinical trials. Bilastine (20 mg), unlike cetirizine, does not increase alcohol effects on the CNS. Bilastine 20 mg does not increase the CNS depressant effect of lorazepam. Bilastine 20 mg is similar to placebo in the driving test. Therefore, it meets the current criteria for medication used in the treatment of allergic rhinitis and urticaria.

Abstract
The effects of urticaria are predominantly mediated by histamine release; therefore, H1-antihistamines are the mainstay of treatment. Second-generation H1-antihistamines, compared with their first-generation counterparts, have demonstrated improved peripheral H1-receptor selectivity and decreased lipophilicity (which minimizes CNS adverse effects), and antiallergic properties in addition to being histamine inverse agonists. Evidence of clinical efficacy and tolerability of second-generation H1-antihistamines available in the US for the treatment of chronic urticaria (CU) was analyzed using the GRADE system to develop the strength of recommendations for particular therapies. The evidence for the safety and efficacy of the majority of second-generation H1-antihistamines available in the US is of high quality and leads to a strong recommendation for their use in CU. There is a limited amount of data of variable quality comparing the efficacy between various second-generation H1-antihistamines in CU leading to weak recommendations for using cetirizine over fexofenadine and levocetirizine over desloratadine. Limited data of variable quality exist for the efficacy of higher doses of second-generation H1-antihistamines in CU patients not responsive to standard doses. These limited data lead to a strong recommendation that higher than recommended doses of fexofenadine do not offer greater efficacy in control of CU and a weak recommendation that higher doses of levocetirizine and desloratadine are more effective in CU unresponsive to standard doses. More studies of higher quality are required to make any firm recommendations regarding second-generation H1-antihistamines in the treatment of physical urticarias. All second-generation H1-antihistamines appear to be very well tolerated in CU patients, with rare reports of adverse effects. Due to the relatively large gaps in the quantity and quality of evidence, particularly for choice of H1-antihistamines, use of higher doses, and use in physical urticarias, greater emphasis in management decisions should be based on the risk/benefit ratio and the patient's personal values and preferences (including cost) in clinical decision making.

Abstract
Allergic rhinitis (AR) is highly prevalent in children. Olopatadine, 0.6% nasal spray (olopatadine) is approved for the relief of seasonal allergic rhinitis (SAR) symptoms in children 6 years of age and older. The objective of this study is to provide a comprehensive report of all clinical studies conducted with olopatadine in children with SAR. A pooled analysis was conducted of 2 randomized, double-blind, 2-week, IRB-approved studies that compared olopatadine with placebo (1 spray/nostril twice-daily) in patients 6-11 years of age with SAR. Assessments included the reflective total nasal symptom score (rTNSS) and total ocular symptom score (rTOSS), the Pediatric Rhinoconjunctivitis Quality-of-Life Questionnaire (PRQLQ), and the Caregiver Treatment Satisfaction Questionnaire for Allergic Rhinitis (CGTSQ-AR). Safety results were reported for these studies in combination with a pediatric pharmacokinetic study. Olopatadine was superior to placebo for mean decrease in rTNSS (p = 0.0012) and rTOSS (p = 0.0094), mean decrease in overall PRQLQ score (p = 0.0003), and mean summary CGTSQ AR score (p = 0.0013); (n = 944). The most frequently reported treatment-related events in the olopatadine group were epistaxis and dysgeusia (bad taste) (n = 1,046). For SAR treatment in patients 6-11 years of age, olopatadine was superior to placebo in reducing the symptoms of SAR, improving quality of life, and satisfying caregivers. Olopatadine is a safe and effective treatment for SAR patients as young as 6 years of age and it has been demonstrated to reduce disease impact on the lives of these children and their families.

Abstract
The article presents the views of pediatric allergologist on the problem of atopic dermatitis/ atopic eczema in children. Atopic dermatitis (AD) is considered from a modern viewpoint of allergic 'march', which is characteristic (typical) for children with atopy. These data indicate to systemic nature of atopic 'march', the first step of which is atopic eczema. Further evolution of atopic dermatitis leads to a transformation of it in other atopic diseases--allergic rhinitis and bronchial asthma; this fact indicates that immunopathological disorders are united in these diseases and it conditions the possibility of prevention. It has taken into consideration the systemic nature of atopic diseases, combined therapy is great important and has to include not only basic local therapy, in particular topical corticosteroids (mometasone furoate--Elokom) during the exacerbation, and the systematic elimination of trigger factors, diet, the removal of the digestive system dysfunctions and the imbalance of vitamins. A long-time systemic basic therapy by H1-antihistamines of second generation, such as desloratadine (Aerius) takes a special place in the treatment of atopic dermatitis.

Abstract
PURPOSE To evaluate the effectiveness of pre-seasonal treatment with topical olopatadine on the reduction of clinical symptoms of seasonal allergic conjunctivitis (SAC). DESIGN Prospective interventional case series. METHODS Eleven patients with SAC received topical olopatadine in one eye at least two weeks before the onset of allergy symptoms, and the other eye served as the control. After the onset of allergic conjunctivitis, both eyes were treated with topical olopatadine. Visual analogue scale (VAS), which evaluated the subjective symptoms of ocular allergy, and the tear levels of histamine and substance P were measured up to six weeks. RESULTS At the onset of allergy symptoms, the VAS score in the pretreatment eyes was statistically significantly lower than that in the control eyes. The VAS score in the control eyes decreased with time but did not decrease to the level seen in the pretreatment eyes until four weeks later. The tear level of substance P at the onset of allergy symptoms was significantly suppressed in the pretreatment eyes, while the level of histamine was not suppressed. Alteration of the VAS scores in the pretreatment eyes significantly correlated with the level of substance P, but not of histamine. CONCLUSIONS To suppress clinical symptoms in patients with SAC, pre-seasonal treatment with topical olopatadine is effective. The effectiveness of treatment correlates with the tear level of substance P.

Abstract
H1-antihistamines are probably the most frequently used drugs in allergic diseases, with widely established efficacy, tolerance, and safety. We report a patient with urticaria due to ingestion of ebastine and fexofenadine. Skin prick tests, patch tests, and basophil activation tests with the implicated drugs and antihistamines from other families were negative. The oral challenges with the implicated antihistamines and other antihistamines tested were positive, but the patient tolerated an oral challenge with cetirizine. We present a patient with urticaria induced by different antihistamines in whom the diagnosis was established by oral challenge. The mechanism of sensitization remains unclear.

Abstract
Physiological normal levels of total cholesterol, total lipids, total protein, superoxide dismutase, catalase, malonic dialdehyde, and total antioxidant activity were determined for the first time in nasal secretion of volunteer donors (n = 24). Excessive lipid peroxidation and suppression of antioxidant protection system were documented in 70 patients with round-the-year allergic rhinitis of whom 26 and 44 presented with the mild and moderately forms of the disease, respectively. The clinical efficiency of polyoxidonium (Russia) in the treatment of allergic rhinitis has been demonstrated. This preparation reduces the intensity of lipid peroxidation and strengthens the antioxidant protection of the organism. The results of the study confirm the high efficacy of combined therapy of allergic rhinitis with aerius and polyoxidonium.

Abstract
Allergic rhinitis is a common disease of great socio-economic significance. The treatment of this condition is carried out on an individual basis depending on the clinical course of the disease; it includes prevention of contacts with the allergen, medicamental and immunotherapy. The principal pharmaceuticals used to treat the patients include oral and intranasal H1 anti-histaminic preparations, intranasal corticosteroids, intranasal cromones, anti-leukotrien agents, and specific subcutaneous immunotherapy. Glencet (levocetirizine) is one of the modern antihistaminic preparations of the second generation having an advantage over other drugs for the treatment of allergic rhinitis in that it may be prescribed to the patients presenting with concomitant bronchial asthma and cardiac diseases.

Abstract
To enhance the solubility and bioavailability of poorly absorbable fexofenadine, microemulsion system composed of oil, surfactant and co-surfactant was developed for intranasal delivery. Phase behavior, particle size, viscosity and solubilization capacity of the microemulsion system were characterized. Histopathology and in vivo nasal absorption of the optimized microemulsion formulations were also investigated in rats. A single isotropic region was found in the pseudo-ternary phase diagrams developed at various ratios with Lauroglycol 90 as oil, Labrasol as surfactant and Plurol Oleique CC49 or its mixture with PEG-400 (1:1) as cosurfactant. An increase in the microemulsion region in pseudo-ternary phase systems was observed with increased surfactant concentration. The optimized microemulsion formulations showed higher solubulization of fexofenadine, i.e., F1 (22.64 mg/mL) and F2 (22.98 mg/mL), compared to its intrinsic water solubility (1.51 mg/mL). Nasal absorption of fexofenadine from these microemulsions was found to be fairly rapid. Tmax was observed within 5 min after intranasal administration at 1.0 mg/kg dose, and the absolute bioavailability (0-4 h) was about 68% compared to the intravenous administration in rats. Our results suggested that these microemulsion formulations could be used as an effective intranasal dosage form for the rapid-onset delivery of fexofenadine

Abstract
The effect of silybinin on the pharmacokinetics of orally and intravenously administered loratadine in rats was investigated. Pharmacokinetic parameters of loratadine were determined in rats following oral (4 mg x kg(-1)) and intravenous (1 mg x kg(-1)) administration to rats in the presence and absence of silybinin (0.3, 1.5 and 6 mg x kg(-1)). Compared to those animals in an oral control group (given loratadine alone), the area under the plasma concentration-time curve (AUC) and the peak plasma concentration (C(max)) of loratadine were increased significantly (P < 0.05 for 1.5 mg x kg(-1), P < 0.01 for 6 mg x kg(-1)) by 50.0-76.7% and 65.4-90.1%, respectively, by silybinin. Consequently, the absolute bioavailability of loratadine in the presence of silybinin (1.5 and 6 mg x kg(-1)) was 8.6-10.2%, which was significantly (1.5 mg x kg(-1), P < 0.05; 6 mg x kg(-1), P < 0.01) enhanced compared to that in oral control group (5.8%). Moreover, the relative bioavailability of loratadine was 1.50- to 1.77-fold greater than that in the control group. In contrast, silybinin had no effect on any pharmacokinetic parameters of loratadine given intravenously, implying that coadministration of silybinin could inhibit the cytochrome P450 (CYP) 3A4-mediated metabolism of loratadine, resulting in reducing gastrointestinal and hepatic first-pass metabolism, and the P-glycoprotein (P-gp) efflux pump in the small intestine. Silybinin significantly enhanced the oral bioavailability of loratadine, suggesting that concurrent use of silybinin and loratadine should be monitored closely for potential drug interactions.

Abstract
OBJECTIVES A new classification of persistent allergic rhinitis (PER) has been developed by the ARIA working group. Although the burden of AR is significant, treatment itself is also costly. It is unclear if treatment based on the new definition of PER is cost-effective. METHODS The current study simulated the cost-effectiveness of desloratadine compared to placebo in the treatment of PER from the French societal perspective. Decision analysis was used to model the costs, effectiveness and cost-effectiveness over 12 months. Costs included medical expenditures (physician visits and prescription drugs) attributable to PER and related comorbidities and lost productivity due to absenteeism and presenteeism. Prices, tariffs and national wages were estimated from French national sources. MEASURES OF EFFECTIVENESS INCLUDED: symptom-based visual analogue scale (VAS), Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), Total 5 Symptoms Score (T5SS), categorical improvement in therapeutic response, interference with activities of daily living (ADL) and sleep outcomes. Mild or symptom-free days and 'responders' were also captured as outcomes. Univariate and second-order multivariate probabilistic sensitivity analyses were conducted. RESULTS Treatment with desloratadine dominated placebo (cost less and resulted in greater effectiveness) for all measures of effectiveness. Of the individuals taking desloratadine 46.8% were classified as 'responders' vs. 34.8% for placebo (p = 0.0012). Individuals taking desloratadine experienced mild/no symptoms for 57.6% of study days vs. 36.5% for placebo (p = 0.002). The expected annual cost of treatment with desloratadine (1819 euro) was less than placebo (2618 euro). Lost productivity was the most significant contributor to total cost. Results of the 10,000 Monte Carlo simulations showed that treatment was cost-saving in 99.6% of simulations. CONCLUSIONS Treatment of PER with desloratadine resulted in improved effectiveness and significant savings. While the cost of drug treatment is greater than that of no treatment, the downstream costs associated with not treating PER significantly outweigh the cost of treatment. Key limitations include the comparison of desloratadine to placebo and the sources of cost and effectiveness measures. Future studies should examine the cost-effectiveness of all available treatments for PER. In addition, many utilization, productivity and effectiveness measures were taken from clinical trials and may not accurately reflect 'real world' treatment patterns and outcomes.

Abstract
BACKGROUND Chronic urticaria is a common condition encountered in general practice and a frequent source of referral to the clinical immunologist, allergist and dermatologist. OBJECTIVE This article discusses the assessment and management of chronic urticaria in the general practice setting. DISCUSSION Chronic urticaria is defined as the occurrence of transient wheals lasting more than 6 weeks in duration. In 80% of cases, a cause is not identified and this is classified as chronic idiopathic urticaria. A physical trigger, vasculitis or systemic disease account for a smaller proportion of cases. Allergic causes are rarely responsible. A detailed history provides the most useful information in determining the presence of chronic urticaria and a possible aetiology. Apart from thyroid function tests and thyroid autoantibodies, other investigations should only be performed if clinically indicated. Second generation antihistamines are the mainstay of treatment and usually twice daily regimens are required for adequate control. H2 antagonists, doxepin and immunomodulation may be necessary in some patients.

Abstract
The oral administration of fexofenadine 120 mg daily is a common treatment of seasonal allergic rhinitis (SAR). It reduces the H1 receptor-mediated symptoms, such as sneezing, pruritus, and nasal secretion as well as non-nasal symptoms such as conjunctivitis. The objective was to assess the effect of fexofenadine on nasal symptoms (such as nasal obstruction) in seasonal allergic rhinitis. A placebo-controlled, double-blind, randomized, cross-over study was performed which yielded evidence that two-week therapy with fexofenadine 120 mg daily in patients with SAR also relieves nasal obstruction and congestion. The parameters of nasal obstruction were evaluated by means of rhinoscopy, a subjective symptom score, and active anterior rhinomanometry. The subjective evaluation of nasal obstruction/congestion as recorded by the patient every 15 minutes for 4.5 hours after nasal allergen provocation showed a significant difference of the AUC (p = 0.025) between fexofenadine and placebo with a 12.8% lower obstruction after fexofenadine. The swelling of the nasal mucosa, which was assessed by rhinoscopy for 4.5 hours after nasal allergen provocation, was 21% lower after treatment with fexofenadine (p = 0.041). In this double-blind, placebo-controlled trial, subjective patient ratings as well as objective investigator assessments demonstrate the anti-obstructive effect of fexofenadine in nasal allergen challenge.

Abstract
Orally disintegrating tablets of levocetirizine dihydrochloride were formulated with different superdisintegrants (sodium starch glycollate, croscarmellose sodium, and crospovidone) using mannitol as a diluent. Tulsion-335, Indion-204, and poly kyron T-134 cation exchange resins were used as taste-masking agents. The drug and resin complex was prepared by the kneading method. Ten formulations were prepared with varying combinations of superdisintegrants and ion-exchange resins by the wet granulation technique, using polyvinylpyrrolidone K-30 as the binder. The prepared tablets were evaluated for degree of taste masking, weight variation, hardness, friability, in vitro and in vivo disintegration time, content uniformity, and water absorption ratio. Dissolution studies were performed in two dissolution media: 0.1N HCl and distilled water. The corresponding dissolution rates were compared with the marketed formulation. Differential scanning calorimetry studies were carried out on the drug-resin complexes. Prepared tablets were good in appearance and showed acceptable results for hardness and friability. In vitro and in vivo disintegration times for the optimum formulation (F-1) were found to be 22 and 55 s, respectively. Relatively acceptable taste was achieved with both Indion-204 and Tulsion-335. Rapid disintegration time was achieved in tablets containing crosspovidone as the superdisintegrant. Dissolution studies indicated the formation of the complex of drug and resin. Differential scanning calorimetry studies indicated the formation of drug-resin complex.

Abstract
BACKGROUND Symptoms of allergic rhinitis (AR), particularly nasal congestion, can impair quality-of-life (QoL). However, only a modest correlation exists between these symptoms and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) scores, suggesting that both be evaluated for a complete assessment of health. METHODS Subjects with a > or =2-year history of moderate-to-severe AR to dust mite or cat dander were randomized to desloratadine 5 mg/day (n = 293) or placebo/day (n = 291) for 28 days. Primary endpoint was change from baseline in a.m./p.m. nasal congestion score. Secondary outcomes included change from baseline in total nasal symptom score, individual symptom scores and RQLQ scores (completed on days 1, 7, and 28). RESULTS The Allergic Rhinitis and its Impact on Asthma criteria for persistent allergic rhinitis (PER) were fulfilled by 99% of subjects in the placebo arm. Between-treatment difference in a.m./p.m. nasal congestion score, observed from day 8 onward, significantly favored desloratadine (P = 0.0003). Desloratadine significantly improved a.m./p.m. nasal congestion and RQLQ scores after 1 week and at treatment end (P < 0.05). Improvements in 5 of 7 RQLQ domain scores exceeded the minimal important difference. On days 7 and 28, desloratadine was also significantly superior to placebo in mean change from baseline in a.m./p.m. total nasal symptom score and rhinorrhea score (both P < or = 0.01). Symptomatic benefit was primarily driven by improvement in nasal congestion and rhinorrhea. CONCLUSIONS Desloratadine 5 mg/day significantly improved symptoms associated with PER, including nasal congestion, and provided significant improvement in QoL after 1 week of treatment.

Abstract
The present study demonstrated that in addition to CYP3A4 and CYP2D6, the metabolism of loratadine is also catalyzed by CYP1A1, CYP2C19, and to a lesser extent by CYP1A2, CYP2B6, CYP2C8, CYP2C9 and CYP3A5. The biotransformation of loratadine was associated with the formation of desloratadine (DL) and further hydroxylation of both DL and the parent drug (loratadine). Based on the inhibition and correlation studies contribution of CYP2C19 in the formation of the major circulating metabolite DL seems to be minor. Reported clinical results suggest that the steady state mean (%CV) plasma Cmax and AUC(24hr) of loratadine were 4.73 ng/ml (119%) and 24.1 ng.hr/ml (157%), respectively, after dosing with 10 mg loratadine tablets for 10 days. High inter-subject variability in loratadine steady-state data is probably due to the phenotypical characteristics of CYP2D6, CYP2C19, and CYP3A4. The relative abundance of CYP3A4 in the human liver exceeds that of CYP2C19 and CYP2D6 and therefore the contribution of CYP3A4 in the metabolism of loratadine should be major (approximately 70%).

Abstract
Allergic rhinitis is the most common allergic disease worldwide and affects about 18% to 40% of the general population. Anti-allergic medicines (eg, some antihistamines) can cause adverse events such as somnolence and can have an additional negative impact on quality of life. Combining montelukast with levocetirizine gives additional benefits in comparison with either drug alone and could be considered for patients whose quality of life is impaired by persistent allergic rhinitis. Montelukast sodium is alkaline, stable and levocetirizine dihydrochloride is acid stable, when we prepare a matrix tablet, both the drugs would be in contact and make it unstable during the shelf life of the formulation. Hence it is recommended to prepare bilayer tablet, as it improves and increases the stability of both the drugs in combination. Bilayer tablet of montelukast with levocetirizine is more stable with respect to stability studies, in comparison to matrix tablet.

Abstract
BACKGROUND Allergic disease affects an estimated 50% of children worldwide and causes considerable impairment in academic performance and daily activities. Pediatric formulations for allergy treatment are often highly sugared or contain ingredients to improve palatability, appearance, and patient acceptance/adherence. These excipients, however, are associated with dental caries, gastrointestinal intolerance, and dermatologic reactions. OBJECTIVE To assess the appeal of new sugar-free/dye-free syrup and orodispersible formulations of the second-generation antihistamine desloratadine to parents of children with allergy in four European countries. DESIGN In an online survey of households with children aged < or =12 years with allergies in France, Italy, the Netherlands, and Spain, respondents were asked to consider one of two desloratadine product concepts: a sugar-free, dye-free oral solution or an orodispersible tablet. PARTICIPANTS Eligible households had to have at least one child aged < or =12 years with symptomatic seasonal, pet, or indoor allergies or hives for > or =1 week/year. Respondents had to be the decision makers regarding their child's allergy medication and to be likely to treat symptoms with prescription medication some of the time. RESULTS There were 627 eligible households. Most (88%) parents in Spain were likely to ask their physician about and to consider trying sugar-free, dye-free desloratadine syrup, followed by 76% of those in France, 68% in Italy, and 56% in the Netherlands. About three-quarters of parents in France, Spain, and Italy and more than half of those in the Netherlands were likely to ask their physician about and to consider trying the orodispersible formulation. LIMITATIONS There is no control group for comparisons between the study's online responses and those that would have resulted from another survey methodology. Further, response biases do exist across countries based on cultural norms. CONCLUSION Survey respondents were generally receptive to the new sugar-free, dye-free syrup and orodispersible tablet formulations of the second-generation antihistamine desloratadine. At least half of parents surveyed indicated their willingness to try the new products.

Abstract
The purpose of this study was to assess the effect of levocetirizine (xyzal) on salivary glands function in patients with allergic rhinitis using technetium-99m pertechnetate ((99m)Tc-P) salivary gland scintigraphy. The study population consisted of 67 patients with allergic rhinitis and 31 healthy controls (14 males and 17 females, mean age 30.1+/-6.8 years). The patients were divided into two groups: an untreated patient Group of 32 patients, 17 males and 15 females, mean age 29.9+/-6.5 years and a levocetirizine-treated with 5mg.day(-1) for 4 weeks patient Group, consisted of 35 patients, 16 males and 19 females, mean age 33.5+/-7.8 years. All patients and healthy controls underwent salivary glands scintigraphy. After the intravenous administration of 185 MBq of (99m)Tc-P, dynamic salivary glands scintigraphy was performed for 25 min. By the time-activity curves, the following glandular function parameters were calculated for the parotid and submandibular salivary glands: uptake ratio, maximum accumulation, and ejection fraction. Our results showed: All functional parameters obtained for the untreated patient Group were significantly lower than for the levocetirizine-treated patient Group and healthy controls (P<0.05). There was no significant difference in any functional parameters between the levocetirizine-treated patient Group and healthy controls (P>0.05). In conclusion, results of our study indicate that patients with allergic rhinitis treated with levocetirizine showed a significantly higher salivary glands function compared with untreated patients and healthy controls. Levocetirizine treatment showed no side effects on salivary glands function.

Abstract
BACKGROUND Chronic idiopathic urticaria (CIU) impairs quality of life (QoL). Currently, no consensus exists regarding how second-generation H(1)-antihistamines (proven to control CIU symptoms) should be taken long-term: as daily treatment or only when symptoms return (PRN). We sought to determine which regimen improves or better maintains QoL in CIU: desloratadine (DL) daily or PRN. METHODS Subjects with CIU initially responding to DL 5 mg/day for 4 weeks were randomized for an additional 8 weeks, to DL 5 mg/day (arm 1: 'continuous', n = 46) or to DL only on days when urticarial wheals were present (arm 2: "PRN", n = 60). To ensure blinding, treatment was presented in both arms as a combination of daily treatment (arm 1: DL; arm 2: placebo), plus a "rescue" tablet (arm 1: placebo; arm 2: DL) to be taken only in case of symptoms. The main outcome measure was QoL assessed by the VQ-Dermato, a validated French QoL instrument, and the Dermatology Life Quality Index (DLQI). RESULTS At 4 and 8 weeks after randomization, subjects taking continuous DL showed statistically significant improvements in VQ-Dermato Global Index score (P = 0.001 and P = 0.016, respectively) and dimension scores for daily living activity, mood state, and social functioning vs subjects taking DL PRN. Improvement in DLQI score at Week 4 was also significantly greater with continuous DL (P = 0.001). CONCLUSION Continuous daily therapy with DL 5 mg is a better regimen than PRN treatment to maintain or improve QoL in subjects with CIU.

Abstract
BACKGROUND Antihistamines are first-line therapy for the treatment of seasonal allergic rhinitis (AR); however, an oral decongestant is often added to improve control of nasal congestion. OBJECTIVE To examine whether a tablet combining the nonsedating antihistamine desloratadine and the decongestant pseudoephedrine was more effective than either drug administered alone in reducing the symptoms of seasonal AR, including nasal congestion. PATIENTS AND METHODS In this multicenter, double-blind study, participants (N = 598) with symptomatic seasonal AR were administered either a combination tablet of desloratadine 2.5 mg/pseudoephedrine 120 mg (DL/PSE) bid, a desloratadine 5.0 mg qd and a placebo tablet, or pseudoephedrine 120 mg bid. Participants assessed their symptom severity twice daily over the 2-week treatment period. RESULTS The primary variable to assess the effects of the antihistamine component--mean change from baseline in average AM/PM reflective total symptom score (TSS), excluding nasal congestion--was significantly greater (-6.54) for DL/PSE than for desloratadine (-5.09) or pseudoephedrine (-5.07) monotherapy (P < .001 for both). The primary variable to assess the effects of the decongestant component--mean change from baseline in average AM/PM reflective nasal congestion score--was also significantly greater (-0.93) for DL/PSE than for desloratadine (-0.66) or pseudoephedrine (-0.75) (P < .001 vs desloratadine; P = .006 vs pseudoephedrine). CONCLUSION This study demonstrated that DL/PSE therapy was more effective in reducing symptoms of seasonal AR, including nasal congestion, than the individual components when administered alone, thus supporting use of this combination in participants with symptomatic seasonal AR and prominent nasal congestion.

Abstract
BACKGROUND Second-generation oral H1-antihistamines have become a mainstay of treatment for the symptoms of seasonal allergic rhinitis; however, the effect of olopatadine has not been widely reported to date. OBJECTIVES To evaluate the efficacy of 2 oral H1-antihistamines, olopatadine and fexofenadine, in the treatment of the nasal symptoms of Japanese cedar pollinosis and their possible side effects. METHODS This was a randomized, double-blind, placebo-controlled, crossover study conducted in an environmental exposure unit (EEU). Twenty volunteers suffering from Japanese cedar pollinosis were randomly divided into 3 groups and exposed to cedar pollen in the EEU with oral administration of olopatadine hydrochloride (5 mg), fexofenadine hydrochloride (60 mg), or placebo 1 hour prior to pollen exposure. Nasal symptoms, activity impairment, and subjective sleepiness were self-assessed during the study period. Attention was measured using the digit cancellation test. The trial was repeated after 4 and 7 weeks. RESULTS Compared with placebo, olopatadine significantly improved nasal symptoms and activity impairment during pollen exposure (P < .05). There was no significant relief of nasal discharge or nasal congestion with fexofenadine throughout the 5-hour exposure to cedar pollen. Furthermore, olopatadine significantly reduced nasal congestion during the first 2 hours, as well as sneezing and nasal discharge 4 hours after admission to the EEU compared with fexofenadine (P < .05). There was no significant difference in the effect on subjective sleepiness among the 3 groups, and all 3 agents had little effect on attention. CONCLUSIONS These findings suggest that olopatadine is more effective than placebo and fexofenadine in improving nasal symptoms of Japanese cedar pollinosis.

Abstract
OBJECTIVE The aim of our study was to determine the diagnostic usefulness of a newly developed basophil activation test (BAT) in patients allergic to Dermatophagoides pteronyssinus and pollens. We also analyzed the influence of cetirizine on CD63 upregulation. This popular antihistamine strongly inhibits skin tests, but its impact on BAT sensitivity remains unknown and deserves at least preliminary determination. METHODS The study sample comprised 22 patients allergic to house dust mite and pollens and 19 healthy controls. All participants underwent skin prick testing and the newly developed flow-cytometric basophil activation test. The protocol for allergen-induced basophil CD63 upregulation consisted of whole blood samples that were processed and stained with anti-CCR3/CD63 antibodies added to the buffer at the beginning of stimulation. Skin prick tests and BAT were performed twice--before and 2 hours after ingestion of 10 mg of cetirizine. RESULTS The new BAT is characterized by its short processing time, easy basophil gating, and strong CD63 upregulation with very high sensitivity and excellent specificity. Our results suggest that allergen-induced CD63 upregulation by higher doses of allergens is not inhibited 2 hours after administration of cetirizine (unlike skin prick tests). CONCLUSION The BAT is a very useful and precise method for the diagnosis of allergy to aeroallergens. It is not influenced by cetirizine.
