Abstract
BACKGROUND Postoperative administration of non-steroidal anti-inflammatory drugs (NSAIDs) reduces patient opioid requirements and, in turn, may reduce the incidence and severity of opioid-induced adverse events (AEs). OBJECTIVES To assess the analgesic efficacy and adverse effects of single-dose intravenous (IV) ibuprofen, compared with placebo or an active comparator, for moderate-to-severe postoperative pain in adults. SEARCH METHODS We searched the following databases without language restrictions: CENTRAL, MEDLINE, Embase and LILACS on 10 June 2021. We checked clinical trials registers and reference lists of retrieved articles for additional studies. SELECTION CRITERIA We included randomized trials that compared a single postoperative dose of intravenous (IV) ibuprofen with placebo or another active treatment, for treating acute postoperative pain in adults following any surgery. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Two review authors independently considered trials for review inclusion, assessed risk of bias, and extracted data. Our primary outcome was the number of participants in each arm achieving at least 50% pain relief over a 4- and 6-hour period. Our secondary outcomes were time to, and number of participants using rescue medication; withdrawals due to lack of efficacy, adverse events (AEs), and for any other cause; and number of participants reporting or experiencing any AE, serious AEs (SAEs), and specific NSAID-related or opioid-related AEs. We were not able to carry out any planned meta-analysis. We assessed the certainty of the evidence using GRADE. MAIN RESULTS Only one study met our inclusion criteria, involving 201 total participants, mostly female (mean age 42 years), undergoing primary, unilateral, distal, first metatarsal bunionectomy (with osteotomy and internal fixation). Ibuprofen 300 mg, placebo or acetaminophen 1000 mg was administered intravenously to participants reporting moderate pain intensity the day after surgery. Since we identified only one study for inclusion, we did not perform any quantitative analyses. The study was at low risk of bias for most domains. We downgraded the certainty of the evidence due to serious study limitations, indirectness and imprecision. Ibuprofen versus placebo Findings of the single study found that at both the 4-hour and 6-hour assessment period, the proportion of participants with at least 50% pain relief was 32% (24/76) for those assigned to ibuprofen and 22% (11/50) for those assigned to placebo. These findings produced a risk ratio (RR) of 1.44 (95% confidence interval (CI) 0.77 to 2.66 versus placebo for at least 50% of maximum pain relief over the 4-hour and 6-hour period (very low-certainty evidence). Median time to rescue medication was 101 minutes for ibuprofen and 71 minutes for placebo (1 study, 126 participants; very low-certainty evidence). The number of participants using rescue medication was not reported within the included study. During the study (1 study, 126 participants), 58/76 (76%) of participants assigned to ibuprofen and 39/50 (78%) assigned to placebo reported or experienced any adverse event (AE), (RR 0.98, 95% CI 0.81 to 1.19; low-certainty evidence). No serious AEs (SAEs) were experienced (1 study, 126 participants; very low-certainty evidence). Ibuprofen versus active comparators Ibuprofen (300 mg) was similar to the active comparator, IV acetaminophen (1000 mg) at 4 hours and 6 hours (1 study, 126 participants). For those assigned to active control (acetaminophen), the proportion of participants with at least 50% pain relief was 35% (26/75) at 4 hours and 31% (23/75) at 6 hours. At 4 hours, these findings produced a RR of 0.91 (95% CI 0.58 to 1.43; very low-certainty evidence) versus active comparator (acetaminophen). At 6 hours, these findings produced a RR of 1.03 (95% CI 0.64 to 1.66; very low-certainty evidence) versus active comparator (acetaminophen). Median time to rescue medication was 101 minutes for ibuprofen and 125 minutes for the active comparator, acetaminophen (1 study, 151 participants; very low-certainty evidence). The number of participants using rescue medication was not reported within the included study. During the study, 8/76 (76%) of participants assigned to ibuprofen and 45/75 (60%) assigned to active control (acetaminophen) reported or experienced any AE, (RR 1.27, 95% CI 1.02 to 1.59; very low-certainty evidence). No SAEs were experienced (1 study, 151 participants; very low-certainty evidence). AUTHORS' CONCLUSIONS There is insufficient evidence to support or refute the suggestion that IV ibuprofen is effective and safe for acute postoperative pain in adults.

Abstract
Buthus martensii Karsch (BmK), is a kind of traditional Chinese medicine, which has been used for a long history for the treatment of many diseases, such as inflammation, pain and cancer. In this study, DKK-SP1/2/3 genes were screened and extracted from the cDNA library of BmK. The DKK-SP1/2/3 were expressed by using plasmid pSYPU-1b in E. coli BL21, and recombinant proteins were obtained by column chromatography. In the xylene-induced mouse ear swelling and carrageenan-induced rat paw swelling model, DKK-SP1 exerted a significant anti-inflammatory effect by inhibiting the expression of Nav1.8 channel. Meanwhile, the release of pro-inflammatory cytokines (COX-2, IL-6) was decreased significantly and the release of anti-inflammatory cytokines (IL-10) were elevated significantly. Moreover, DKK-SP1 could significantly decrease the Nav1.8 current in acutely isolated rat DRG neurons. In the acetic acid-writhing and ION-CCI model, DKK-SP2 displayed significant analgesic activity by inhibiting the expression of the Nav1.7 channel. Moreover, DKK-SP2 could significantly inhibit the Nav1.7 current in the hNav1.7-CHO cells.

Abstract
Pain management in both outpatient and inpatient settings demands a multidisciplinary approach entailing medical, physical and psychological therapies. Among these, multimodal analgesic regimens stand out as a promising treatment options. Cyclo-oxygenase (COX) inhibitor/opioid receptor agonist combinations hold great potential as effective pillars in the multimodal pain management by providing adequate analgesia with fewer safety risks due to COX inhibitors’ opioid-sparing effect. Thus, these combinations, either freely or in fixed-dose formulation, offer a feasible option for the prescribing clinicians who seek to maximise therapeutic effect while simultaneously minimise adverse effects. The selection of the appropriate non-steroidal anti-inflammatory drug (NSAID) and opioid agent at optimal doses is essential. It should be tailored to the patients’ analgesic necessities, and his/her gastrointestinal and cardiovascular risk, and potential concurrent aspirin use. Moreover, it should allow for addiction risk and the potential opioid-induced bowel dysfunction and constipation. To ensure an optimal match between the characteristics of the patient and the properties of the chosen medication, and to guide adequate and well-tolerated treatment decisions, it is of paramount importance to expand clinicians’ knowledge of the currently available COX inhibitor/opioid receptor agonist combinations. This invited narrative review deals with the literature evidence covering the components of multimodal opioid-sparing analgesic regimens. Also, it provides insights into the clinically relevant choice criteria to ensure a patient-tailored analgesia.

The combined use of systemic analgesic/anti-inflammatory drugs and a bioactive topical desensitizer for reduced in-office bleaching sensitivity without jeopardizing the hydrogen peroxide efficacy: a randomized, triple blinded, split-mouth clinical trial. Clin Oral Investig 2021; 25:6623-6632. [PMID: 33884504 DOI: 10.1007/s00784-021-03948-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Accepted: 04/12/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE To evaluate the effect of combined systemic administration of paracetamol 500 mg/codeine phosphate 30 mg (PACO) and postoperative topical application of a bioactive desensitizer on in-office bleaching sensitivity and tooth color change. MATERIALS AND METHODS A randomized, triple-blind, split-mouth clinical trial was conducted. Forty volunteers ingested PACO (n = 20) or placebo (PLA) (n = 20). Their left/right hemiarches received topical application of a bioactive desensitizer [Nano-P™(NP)] and prophylactic paste (PAS), generating four treatment approaches: PACO/NP, PACO/PAS, PLA/NP, and PLA/PAS. Two bleaching sessions (35% hydrogen peroxide) were performed, and the PAS/NP were applied after the procedure. Sensitivity was obtained since the first bleaching session up to 7 days post-bleaching. The color change was evaluated using CIEDE2000 and whiteness index parameters up to 7 days post-bleaching. Data were analyzed using one- and two-way ANOVA/Tukey post hoc tests (p < 0.05). RESULTS The PLA/PAS showed a sensitivity average of at least two times higher than the PACO/NP. The treatment approaches promoted statistically similar bleaching patterns (p > 0.05). CONCLUSION The combined approach of systemic administration of PACO and postoperative topical application of NP reduced the level of in-office bleaching sensitivity without jeopardizing hydrogen peroxide efficacy. CLINICAL RELEVANCE Professionals can adopt the combined approach of systemic administration of analgesic/anti-inflammatory drugs and topical application of a bioactive desensitizer for decreased bleaching sensitivity caused by 35% hydrogen peroxide in-office.

Abstract
BACKGROUND Misuse and dependency of opioids especially codeine-containing products is of increasing global concern. Inappropriate use of opioids among healthcare students could affect quality of service and ethical conducts of these future professionals, thereby putting the society at risk. This study aimed to evaluate knowledge and perception of medical and pharmacy students in a Nigerian tertiary University on use of opioids with focus on codeine-containing products. METHODS A cross-sectional survey among 335-medical and 185-pharmacy students from University of Ibadan, Nigeria, between September and December 2018, using a self-administered semi-structured questionnaire. RESULTS A total of 178 (34.2%) in multiple responses had used opioid-containing products among the respondents, of this, 171 (96.1%) used codeine-containing formulation. Precisely, 146 (28.1%) of the students had used codeine-containing products before, of this, 16 (11.0%) used the products for non-medical or recreational purpose regarded as a misuse/abuse. In all, 201 (38.7%) had good knowledge of opioid use, with 51 (34.9%) among those who had used opioids and 150 (40.1%) among those who had not used opioids (X2 = 1.186; p = 0.276). Majority (469; 90.2%) had good perception of risks associated with opioid use; comprising (130; 89.0%) among those who had taken opioids and (339; 90.6%) among those who had not taken opioids before (X2 = 0.304; p = 0.508). Logistic-regression shows that students who experienced some side effects to be experienced again 22.1 [AOR = 22.1, 95% CI: (5.98-81.72)] as well as those pressured into using codeine-containing products 10.6 [AOR = 10.6, 95% CI: (1.36-82.39)] had more tendency of misuse. CONCLUSION There is a potential for misuse of codeine-containing products among medical and pharmacy students. Peer-influence and experience of some side effects are possible predictors of misuse among the students. Thus, healthcare students' curriculum should incorporate preventive programme, while public education and policy that favours peer-support programme on medication misuse is advocated for healthcare students.

Abstract
BACKGROUND The misuse of codeine is of increasing concern in a number of countries, particularly as this relates to over -the-counter pain and cough relief medication, and is also supplied as a prescription medicine. The study aimed to obtain and analyse the opinions and experience of pharmacy staff with regard to codeine misuse. METHODS A cross-sectional web-based survey of pharmacy staff's perspectives on this issue was administered through professional or regulatory bodies and completed by samples drawn in South Africa (n = 124), Ireland (n = 464) and the United Kingdom (n = 129). RESULTS The majority of participants reported combination codeine-containing products as most popular, but significantly more pharmacy staff in South Africa reported codeine-containing cough syrups as most commonly popular (X2 = 122.7(2), p < 0.001). Codeine use was also seen significantly more of a public health problem in South Africa than in the other two countries (X2 = 7.6(2), p = 0.02). There was no difference across countries in the level of codeine misuse reported by pharmacy staff. Further findings indicate that professional training and education is desired, with unequivocal findings for the need for greater codeine control (X2 = 12.0(2), p = 0.002). CONCLUSION In conclusion, there were some inter-country differences, but overall the findings seem to suggest that pharmacists across all three countries view codeine misuse as a problem among their customers. Recommendations centre on risk management, surveillance and staff training.

Abstract
BACKGROUND Combining two different analgesics in fixed doses in a single tablet can provide better pain relief than either drug alone in acute pain. This appears to be broadly true across a range of different drug combinations, in postoperative pain and migraine headache. A new combination of dexketoprofen (a nonsteroidal anti-inflammatory drug) plus tramadol (an opioid) has been tested in acute postoperative pain conditions. It is not yet licensed for use. This review is one of a series on oral analgesics for acute postoperative pain. Individual reviews have been brought together in two overviews to provide information about the relative efficacy and harm of the different interventions. OBJECTIVES To assess the analgesic efficacy and adverse effects of a single fixed-dose of oral dexketoprofen plus tramadol, compared with placebo, for moderate to severe postoperative pain in adults, using methods that permit comparison with other analgesics evaluated in standardised trials using almost identical methods and outcomes. A secondary objective was to compare the combination with the individual analgesics alone. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) via CRSO, MEDLINE via Ovid, and Embase via Ovid from inception to 31 May 2016. We also searched the reference lists of retrieved studies and reviews, and two online clinical trial registries. SELECTION CRITERIA Randomised, double-blind trials of oral dexketoprofen plus tramadol administered as a single oral dose, for the relief of acute postoperative pain in adults, and compared to placebo. DATA COLLECTION AND ANALYSIS Two review authors independently considered trials for inclusion in the review, examined issues of study quality and potential bias, and extracted data. For dichotomous outcomes, we calculated risk ratio (RR) and number needed to treat for an additional beneficial outcome (NNT) for dexketoprofen plus tramadol, compared with placebo with 95% confidence intervals (CI). We collected information on the number of participants with at least 50% of the maximum possible pain relief over six hours, the median time to use of rescue medication, and the proportion of participants requiring rescue medication. We also collected information on adverse events and withdrawals. We assessed the quality of the evidence using GRADE and created a 'Summary of findings' table.We also collected information on the number of participants with at least 50% of the maximum possible pain relief over six hours for dexketoprofen alone and tramadol alone. MAIN RESULTS We included three studies with 1853 participants who had undergone surgical removal of impacted wisdom teeth, hip replacement, or hysterectomy. The overall risk of bias across the three included studies was low, with unclear risk of bias in relation to the size of the three studies. Two studies did not report all our prespecified outcomes, which limited the analyses we could do.The proportion of participants achieving at least 50% pain relief over six hours with dexketoprofen 25 mg plus tramadol 75 mg was 66%, compared to 32% with placebo, giving an NNT of 3.0 (95% CI 2.5 to 3.7) (RR 2.1 (95% CI 1.7 to 2.4); 748 participants; 3 studies) (moderate quality evidence). The response rate with dexketoprofen 25 mg alone was 53% (RR 1.3 (95% CI 1.1 to 1.4); 744 participants; 3 studies) and with tramadol alone was 45% (RR 1.5 (95% CI 1.3 to 1.7); 741 participants; 3 studies) (moderate quality evidence). We downgraded the evidence because of some inconsistency in the results.The median time to use of rescue medication could not be estimated exactly, but was probably eight hours or more, indicating a long duration of effect (moderate quality evidence). We downgraded the evidence because it was not possible to estimate the effect exactly in the two multiple dose studies, resulting in imprecision. Fewer participants used rescue medication with higher doses of active treatment (summary statistic not calculated; 123 participants; 1 study) (very low quality evidence). We downgraded the evidence because the data came from a single study with few participants and events.Adverse events and serious adverse events were not reported consistently for the single dose phase of the studies. In the single dose study, 11% of participants experienced adverse events with dexketoprofen 25 mg plus tramadol 75 mg, which were mostly mild or moderate nausea, vomiting, or dizziness, and typical with these medicines. Rates were lower with placebo and lower doses (very low quality evidence). We downgraded the evidence because the data came from a single study with few participants and events. Information on multiple dosing over three and five days supported a low event rate with the combination. Overall, rates were generally low in all treatment arms, as they were for withdrawals for adverse events or other reasons. AUTHORS' CONCLUSIONS A single oral dose of dexketoprofen 25 mg plus tramadol 75 mg provided good levels of pain relief with long duration of action to more people than placebo or the same dose of dexketoprofen or tramadol alone. The magnitude of the effect was similar to other good analgesics. Adverse event rates were low.There is modest uncertainty about the precision of the point estimate for efficacy, but the NNT of 3 is consistent with other analgesics considered effective and commonly used.

Abstract
PURPOSE There has been concern regarding the increasing use of opioids and related harm. We present data on opioid utilisation across Australia and consider sociodemographic factors that may affect utilisation rates. METHODS IMS Health national sales data for over-the-counter (codeine) and prescription opioids (buprenorphine, codeine, dextropropoxyphene, fentanyl, hydromorphone, methadone, morphine, oxycodone, tapentadol and tramadol) were used to estimate total utilisation rates in the community during 2013, mapped to Statistical Local Areas (SLAs) and Remoteness Areas. All opioid amounts were measured in pack sales and milligrammes then converted to oral morphine equivalent milligrammes (OME mg) for comparison across opioids. Data on the demographic characteristics of SLAs were obtained from the ABS (sex and age distribution, income and levels of physical labour) and other sources (number of pharmacies in SLAs) and were included in linear regression analyses. RESULTS In 2013, an estimated 10 747 kg (OME) of opioids were sold across Australia, equating to 481 OME mg per person. There was considerable geographic variation in opioid utilisation, with higher rates of use in rural and regional areas. Geographic areas that were less populated, had more men and older people, proportionally more low-income earning households and greater proportions in jobs requiring physical labour had higher utilisation rates. CONCLUSIONS Substantial geographic variation in opioid utilisation was identified, with areas outside of major cities having higher rates of utilisation of all types of opioids. Prescription monitoring and best practice interventions aimed at improving opioid use need to have a particular focus on areas outside of major cities. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
BACKGROUND Non-prescription (over-the-counter, or OTC) analgesics (painkillers) are used frequently. They are available in various brands, package sizes, formulations, and dose. They can be used for a range of different types of pain, but this overview reports on how well they work for acute pain (pain of short duration, usually with rapid onset). Thirty-nine Cochrane reviews of randomised trials have examined the analgesic efficacy of individual drug interventions in acute postoperative pain. OBJECTIVES To examine published Cochrane reviews for information about the efficacy of pain medicines available without prescription using data from acute postoperative pain. METHODS We identified OTC analgesics available in the UK, Australia, Canada, and the USA by examining online pharmacy websites. We also included some analgesics (diclofenac potassium, dexketoprofen, dipyrone) of importance in parts of the world, but not currently available in these jurisdictions.We identified systematic reviews by searching the Cochrane Database of Systematic Reviews (CDSR) on The Cochrane Library through a simple search strategy. All reviews were overseen by a single review group, had a standard title, and had as their primary outcome numbers of participants with at least 50% pain relief over four to six hours compared with placebo. From individual reviews we extracted the number needed to treat for an additional beneficial outcome (NNT) for this outcome for each drug/dose combination, and also calculated the success rate to achieve at least 50% of maximum pain relief. We also examined the number of participants experiencing any adverse event, and whether the incidence was different from placebo. MAIN RESULTS We found information on 21 different OTC analgesic drugs, doses, and formulations, using information from 10 Cochrane reviews, supplemented by information from one non-Cochrane review with additional information on ibuprofen formulations (high quality evidence). The lowest (best) NNT values were for combinations of ibuprofen plus paracetamol, with NNT values below 2. Analgesics with values close to 2 included fast acting formulations of ibuprofen 200 mg and 400 mg, ibuprofen 200 mg plus caffeine 100 mg, and diclofenac potassium 50 mg. Combinations of ibuprofen plus paracetamol had success rates of almost 70%, with dipyrone 500 mg, fast acting ibuprofen formulations 200 mg and 400 mg, ibuprofen 200 mg plus caffeine 100 mg, and diclofenac potassium 50 mg having success rates above 50%. Paracetamol and aspirin at various doses had NNT values of 3 or above, and success rates of 11% to 43%. We found no information on many of the commonly available low dose codeine combinations.The proportion of participants experiencing an adverse event were generally not different from placebo, except for aspirin 1000 mg and (barely) ibuprofen 200 mg plus caffeine 100 mg. For ibuprofen plus paracetamol, adverse event rates were lower than with placebo. AUTHORS' CONCLUSIONS There is a body of reliable evidence about the efficacy of some of the most commonly available drugs and doses widely available without prescription. The postoperative pain model is predominantly pain after third molar extraction, which is used as the industry model for everyday pain. The proportion of people with acute pain who get good pain relief with any of them ranges from around 70% at best to less than 20% at worst; low doses of some drugs in fast acting formulations were among the best. Adverse events were generally no different from placebo. Consumers can make an informed choice based on this knowledge, together with availability and price. Headache and migraine were not included in this overview.

Abstract
BACKGROUND This is an update of a Cochrane overview published in Issue 9, 2011; that overview considered both efficacy and adverse events. This overview considers adverse events, with efficacy dealt with in a separate overview.Thirty-nine Cochrane reviews of randomised trials have examined the adverse events associated with individual drug interventions in acute postoperative pain. This overview brings together the results of those individual reviews. OBJECTIVES To provide an overview of adverse event rates associated with single-dose oral analgesics, compared with placebo, for acute postoperative pain in adults. METHODS We identified systematic reviews in The Cochrane Database of Systematic Reviews on The Cochrane Library through a simple search strategy. All reviews were overseen by a single review group. We extracted information related to participants experiencing any adverse event, and reports of serious adverse events, and deaths from the individual reviews. MAIN RESULTS Information was available from 39 Cochrane reviews for 41 different analgesics or analgesic combinations (51 drug/dose/formulations) tested in single oral doses in participants with moderate or severe postoperative pain. This involved around 350 unique studies involving about 35,000 participants. Most studies involved younger participants with pain following removal of molar teeth.For most nonsteroidal anti-inflammatory drugs (NSAIDs), paracetamol, and combinations not containing opioids, there were few examples where participants experienced significantly more or fewer adverse events than with placebo. For aspirin 1000 mg and diflunisal 1000 mg, opioids, or fixed-dose combination drugs containing opioids, participants typically experienced significantly more adverse events than with placebo. Studies of combinations of ibuprofen and paracetamol reported significantly fewer adverse events.Serious adverse events were rare, occurring a rate of about 1 in 3200 participants.Most reviews did not report specific adverse events. AUTHORS' CONCLUSIONS Despite ongoing problems with the measurement, recording, and reporting of adverse events in clinical trials and in systematic reviews, the large amount of information available for single oral doses of analgesics provides evidence that adverse events rates are generally similar with active drug and placebo in these circumstances, except at higher doses of some drugs, and in combinations including opioids.

Abstract
BACKGROUND This is an updated version of the original Cochrane overview published in Issue 9, 2011. That overview considered both efficacy and adverse events, but adverse events are now dealt with in a separate overview.Thirty-nine Cochrane reviews of randomised trials have examined the analgesic efficacy of individual drug interventions in acute postoperative pain. This overview brings together the results of those individual reviews and assesses the reliability of available data. OBJECTIVES To summarise the efficacy of pharmaceutical interventions for acute pain in adults with at least moderate pain following surgery who have been given a single dose of oral analgesic. METHODS We identified systematic reviews in the Cochrane Database of Systematic Reviews in The Cochrane Library through a simple search strategy. All reviews were overseen by a single review group, had a standard title, and had as their primary outcome the number of participants with at least 50% pain relief over four to six hours compared with placebo. For individual reviews, we extracted the number needed to treat for an additional beneficial outcome (NNT) for this outcome for each drug/dose combination, and also the percentage of participants achieving at least 50% maximum pain relief, the mean of mean or median time to remedication, and the percentage of participants remedicating by six, eight, 12, or 24 hours. Where there was adequate information for pairs of drug and dose (at least 200 participants, in at least two studies), we defined the addition of four comparisons of typical size (400 participants in total) with zero effect as making the result potentially subject to publication bias and therefore unreliable. MAIN RESULTS The overview included 39 separate Cochrane Reviews with 41 analyses of single dose oral analgesics tested in acute postoperative pain models, with results from about 50,000 participants in approximately 460 individual studies. The individual reviews included only high-quality trials of standardised design, methods, and efficacy outcome reporting. No statistical comparison was undertaken.Reliable results (high quality information) were obtained for 53 pairs of drug and dose in painful postsurgical conditions; these included various fixed dose combinations, and fast acting formulations of some analgesics. NNTs varied from about 1.5 to 20 for at least 50% maximum pain relief over four to six hours compared with placebo. The proportion of participants achieving this level of benefit varied from about 30% to over 70%, and the time to remedication varied from two hours (placebo) to over 20 hours. Good (low) NNTs were obtained with ibuprofen 200 mg plus paracetamol (acetaminophen) 500 mg (NNT compared with placebo 1.6; 95% confidence interval 1.5 to 1.8), ibuprofen fast acting 200 mg (2.1; 1.9 to 2.3); ibuprofen 200 mg plus caffeine 100 mg (2.1; 1.9 to 3.1), diclofenac potassium 50 mg (2.1; 1.9 to 2.5), and etoricoxib 120 mg (1.8; 1.7 to 2.0). For comparison, ibuprofen acid 400 mg had an NNT of 2.5 (2.4 to 2.6). Not all participants had good pain relief and, for many pairs of drug and dose, 50% or more did not achieve at least 50% maximum pain relief over four to six hours.Long duration of action (eight hours or greater) was found for etoricoxib 120 mg, diflunisal 500 mg, paracetamol 650 mg plus oxycodone 10 mg, naproxen 500/550 mg, celecoxib 400 mg, and ibuprofen 400 mg plus paracetamol 1000 mg.There was no evidence of analgesic effect for aceclofenac 150 mg, aspirin 500 mg, and oxycodone 5 mg (low quality evidence). No trial data were available in reviews of acemetacin, meloxicam, nabumetone, nefopam, sulindac, tenoxicam, and tiaprofenic acid. Inadequate amounts of data were available for nine drugs and doses, and data potentially susceptible to publication bias for 13 drugs and doses (very low quality evidence). AUTHORS' CONCLUSIONS There is a wealth of reliable evidence on the analgesic efficacy of single dose oral analgesics. Fast acting formulations and fixed dose combinations of analgesics can produce good and often long-lasting analgesia at relatively low doses. There is also important information on drugs for which there are no data, inadequate data, or where results are unreliable due to susceptibility to publication bias. This should inform choices by professionals and consumers.
