Abstract
BACKGROUND Children often require pain management following surgery to avoid suffering. Effective pain management has consequences for healing time and quality of life. Ibuprofen, a frequently used non-steroidal anti-inflammatory drug (NSAID) administered to children, is used to treat pain and inflammation in the postoperative period. OBJECTIVES 1) To assess the efficacy and safety of ibuprofen (any dose) for acute postoperative pain management in children compared with placebo or other active comparators. 2) To compare ibuprofen administered at different doses, routes (e.g. oral, intravenous, etc.), or strategies (e.g. as needed versus as scheduled). SEARCH METHODS We used standard Cochrane search methods. We searched CENTRAL, MEDLINE, Embase, CINAHL and trials registries in August 2023. SELECTION CRITERIA We included randomised controlled trials (RCTs) in children aged 17 years and younger, treated for acute postoperative or postprocedural pain, that compared ibuprofen to placebo or any active comparator. We included RCTs that compared different administration routes, doses of ibuprofen and schedules. DATA COLLECTION AND ANALYSIS We adhered to standard Cochrane methods for data collection and analysis. Our primary outcomes were pain relief reported by the child, pain intensity reported by the child, adverse events, and serious adverse events. We present results using risk ratios (RR) and standardised mean differences (SMD), with the associated confidence intervals (CI). We used GRADE to assess the certainty of the evidence. MAIN RESULTS We included 43 RCTs that enroled 4265 children (3935 children included in this review). We rated the overall risk of bias at the study level as high or unclear for 37 studies that had one or several unclear or high risk of bias judgements across the domains. We judged six studies as having a low risk of bias across all domains. Ibuprofen versus placebo (35 RCTs) No studies reported pain relief reported by the child or a third party, or serious adverse events. Ibuprofen probably reduces child-reported pain intensity less than two hours postintervention compared to placebo (SMD -1.12, 95% CI -1.39 to -0.86; 3 studies, 259 children; moderate-certainty evidence). Ibuprofen may reduce child-reported pain intensity, two hours to less than 24 hours postintervention (SMD -1.01, 95% CI -1.24 to -0.78; 5 studies, 345 children; low-certainty evidence). Ibuprofen may result in little to no difference in adverse events compared to placebo (RR 0.79, 95% CI 0.51 to 1.23; 5 studies, 384 children; low-certainty evidence). Ibuprofen versus paracetamol (21 RCTs) No studies reported pain relief reported by the child or a third party, or serious adverse events. Ibuprofen likely reduces child-reported pain intensity less than two hours postintervention compared to paracetamol (SMD -0.42, 95% CI -0.82 to -0.02; 2 studies, 100 children; moderate-certainty evidence). Ibuprofen may slightly reduce child-reported pain intensity two hours to 24 hours postintervention (SMD -0.21, 95% CI -0.40 to -0.02; 6 studies, 422 children; low-certainty evidence). Ibuprofen may result in little to no difference in adverse events (0 events in each group; 1 study, 44 children; low-certainty evidence). Ibuprofen versus morphine (1 RCT) No studies reported pain relief or pain intensity reported by the child or a third party, or serious adverse events. Ibuprofen likely results in a reduction in adverse events compared to morphine (RR 0.58, 95% CI 0.40 to 0.83; risk difference (RD) -0.25, 95% CI -0.40 to -0.09; number needed to treat for an additional beneficial outcome (NNTB) 4; 1 study, 154 children; moderate-certainty evidence). Ibuprofen versus ketorolac (1 RCT) No studies reported pain relief or pain intensity reported by the child, or serious adverse events. Ibuprofen may result in a reduction in adverse events compared to ketorolac (RR 0.51, 95% CI 0.27 to 0.96; RD -0.29, 95% CI -0.53 to -0.04; NNTB 4; 1 study, 59 children; low-certainty evidence). AUTHORS' CONCLUSIONS Despite identifying 43 RCTs, we remain uncertain about the effect of ibuprofen compared to placebo or active comparators for some critical outcomes and in the comparisons between different doses, schedules and routes for ibuprofen administration. This is largely due to poor reporting on important outcomes such as serious adverse events, and poor study conduct or reporting that reduced our confidence in the results, along with small underpowered studies. Compared to placebo, ibuprofen likely results in pain reduction less than two hours postintervention, however, the efficacy might be lower at two hours to 24 hours. Compared to paracetamol, ibuprofen likely results in pain reduction up to 24 hours postintervention. We could not explore if there was a different effect in different kinds of surgeries or procedures. Ibuprofen likely results in a reduction in adverse events compared to morphine, and in little to no difference in bleeding when compared to paracetamol. We remain mostly uncertain about the safety of ibuprofen compared to other drugs.

Abstract
Pain associated with infections of the tooth pulp and periapical tissues is intense and often the most common reason for patients seeking emergency dental care. Effective management of acute dental pain requires a deep understanding of pain mechanisms, which enables accurate diagnosis and definitive treatment. While drugs are only used as an adjunct to definitive dental treatment, a thorough understanding of their mechanism of action and effectiveness enables clinicians to effectively control intra-operative and post-operative pain and prevent persistent pain. This review describes how pain is detected, processed, and perceived. It also provides information on evidence-based strategies on the use of different classes of drugs to effectively manage endodontic pain.

A Meta-Analysis of the Analgesic Efficacy of Single-Doses of Ibuprofen Compared to Traditional Non-Opioid Analgesics Following Third Molar Surgery. Pharmaceuticals (Basel) 2021; 14:ph14040360. [PMID: 33919715 PMCID: PMC8070746 DOI: 10.3390/ph14040360] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2021] [Accepted: 04/08/2021] [Indexed: 01/10/2023] Open
Abstract
The purpose of this systematic review was to determine the analgesic efficacy and adverse effects of ibuprofen in comparison with other traditional non-opioid analgesics after third molar surgery. A total of 17 full texts were identified in PubMed and assessed using the Cochrane Collaboration’s risk of bias tool by two independent researchers. The sum of pain intensity differences, total pain relief, the overall evaluation, the number of patients requiring rescue analgesics, and adverse effects were collected. Data were analyzed using the Review Manager Software 5.3. for Windows. A total of 15 articles met the criteria. The qualitative and quantitative analysis showed that ibuprofen is more effective to relieve post-operative dental pain than acetaminophen, meclofenamate, aceclofenac, bromfenac, and aspirin. Moreover, ibuprofen and traditional non-steroidal anti-inflammatory drugs have a similar safety profile. In conclusion, ibuprofen 400 mg appears to have good analgesic efficacy and a safety profile similar to other traditional non-steroidal anti-inflammatory drugs after third molar surgery.

Abstract
Postsurgical dental pain is mainly driven by inflammation, particularly through the generation of prostaglandins via the cyclooxygenase system. Thus, it is no surprise that numerous randomized placebo-controlled trials studying acute pain following the surgical extraction of impacted third molars have demonstrated the remarkable efficacy of nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, naproxen sodium, etodolac, diclofenac, and ketorolac in this prototypic condition of acute inflammatory pain. Combining an optimal dose of an NSAID with an appropriate dose of acetaminophen appears to further enhance analgesic efficacy and potentially reduce the need for opioids. In addition to being on average inferior to NSAIDs as analgesics in postsurgical dental pain, opioids produce a higher incidence of side effects in dental outpatients, including dizziness, drowsiness, psychomotor impairment, nausea/vomiting, and constipation. Unused opioids are also subject to misuse and diversion, and they may cause addiction. Despite these risks, some dental surgical outpatients may benefit from a 1- or 2-d course of opioids added to their NSAID regimen. NSAID use may carry significant risks in certain patient populations, in which a short course of an acetaminophen/opioid combination may provide a more favorable benefit versus risk ratio than an NSAID regimen.

Abstract
Trauma or injury to the dentition and supporting tissues is associated with pain and discomfort, as expected, that may present immediately, shortly afterwards, or within a few days. Pain is an essential response to injury because it allows the organism to develop avoidance behavior to potential threats and helps the organism to avoid usage of the injured organ during the healing process. Not only does external trauma induce pain, but also essential invasive dental procedures such as extractions, dental implant insertions, root canal treatments, and oral surgeries are accompanied by similar post-surgical (post-traumatic) pain. The pain intensity after trauma varies and does not always correlate with the extent of injury. Trauma to the orofacial region or the teeth may also indirectly affect and induce pain in other orofacial structures such as the masticatory muscles, the temporomandibular joint, and even the cervical spine. In most cases, the pain will resolve as soon as healing of the affected tissue occurs or after dental and routine palliative treatment. In a limited number of cases, the pain persists beyond healing and evolves into a chronic pain state. Chronic pain in the orofacial region presents diagnostic and management challenges. Misdiagnosis or delayed diagnosis of the oral chronic pain condition may lead to unnecessary dental treatment. This article will discuss diagnosis and treatment for acute and chronic pain as well as potential mechanisms involved in the undesirable transition from acute to chronic pain.

Abstract
Abstract
Objectives
The objective of this review was to provide an overview of pharmacokinetic/pharmacodynamic (PK/PD) models, focusing on drug-specific PK/PD models and highlighting their value added in drug development and regulatory decision-making.
Key findings
Many PK/PD models, with varying degrees of complexity and physiological understanding have been developed to evaluate the safety and efficacy of drug products. In special populations (e.g. paediatrics), in cases where there is genetic polymorphism and in other instances where therapeutic outcomes are not well described solely by PK metrics, the implementation of PK/PD models is crucial to assure the desired clinical outcome. Since dissociation between the pharmacokinetic and pharmacodynamic profiles is often observed, it is proposed that physiologically based pharmacokinetic and PK/PD models be given more weight by regulatory authorities when assessing the therapeutic equivalence of drug products.
Summary
Modelling and simulation approaches already play an important role in drug development. While slowly moving away from ‘one-size fits all’ PK methodologies to assess therapeutic outcomes, further work is required to increase confidence in PK/PD models in translatability and prediction of various clinical scenarios to encourage more widespread implementation in regulatory decision-making.

Abstract
The increasing number of scientific publications focusing on nanomaterials in the biomedical field indicates growing interest from the broader scientific community. Nanomedicine is a modern science, and research continues into the application of nanoscale materials for the therapy and diagnosis of damaged tissues. In this regard, substantial progress has been made in the synthesis of magnetic materials with desired sizes, morphologies, chemical compositions, and surface chemistry. Among these, magnetic iron oxide nanoparticles have demonstrated great promise as unique carriers in the delivery of chemical drugs due to their combinations of hollow structures. Importantly, due to the combination of the ability to respond to an external magnetic field and the rich possibilities of their coatings, magnetic materials are universal tools for the magnetic separation of small molecules, biomolecules, and cells. This review provides an overview of the synthesis and biological applications of hollow magnetic nanoparticles in drug delivery systems. The increasing number of scientific publications focusing on nanomaterials in the biomedical field indicates growing interest from the broader scientific community.![]()

Abstract
It has been known for centuries that opioids are highly addictive when consumed for prolonged periods of time. Pharmacologic tolerance to the efficacy of opioid analgesic results in a need for increased dosing and drug dependence. One must question the empirical sources of evidence that justified the belief that prescription opioids were safe and effective for treating acute and chronic pain. Progress in developing and applying evidence-based analgesic therapies for acute inflammatory pain is presented.

Abstract
Analgesic effects of ibuprofen immediate‐release/extended‐release (IR/ER) 600‐mg tablets were evaluated in 2 randomized, double‐blind, placebo‐controlled dental pain studies. Patients 16–40 years old with moderate–severe pain following third‐molar extraction received single‐dose ibuprofen 600 mg IR/ER (formulation A or B), naproxen sodium 220 mg, or placebo (2:2:2:1; study 1) or 4 doses of ibuprofen 600 mg IR/ER (formulation A) or placebo (1:1; study 2). In study 1 (n = 196), mean (standard deviation [SD]) time‐weighted sum of pain intensity difference scores for placebo, ibuprofen IR/ER A, ibuprofen IR/ER B, and naproxen, respectively, were 0.05 (9.2), 16.87 (9.4), 17.34 (10.5), and 12.66 (10.0) over 0–12 hours and ‐0.03 (4.1), 6.57 (4.4), 7.14 (5.2), and 5.14 (5.0) over 8–12 hours (all P < .001 vs placebo). In study 2 (n = 106), mean (SD) time‐weighted sum of pain relief and pain intensity difference scores were 18.2 (20.0) versus 41.5 (21.0) at 0–12 hours and 10.3 (12.0) versus 18.4 (12.1) at 8–12 hours for placebo versus ibuprofen IR/ER, respectively (P < .001 for both); efficacy was sustained over each of the four 12‐hour dosing intervals with ibuprofen. Gastrointestinal adverse events predominated with placebo both after study medication administration and after rescue medication use, if applicable. Ibuprofen 600 mg IR/ER provided safe and effective analgesia after single and multiple doses.

Abstract
The results of numerous double-blind, placebo-controlled clinical trials consistently demonstrate that nonsteroidal antiinflammatory drugs should be the first line agents in treating postsurgical dental pain. Additive and potential opioid-sparing effects have also been reported in oral surgery pain by combining an optimal dose of an NSAID with acetaminophen 500 mg. While opioid combination drugs are indicated in some dental postsurgical patients, clinicians can no longer ignore the scourge of prescription opioid abuse in the United States. Other potential opioid sparing strategies include the use of locally delivered antimicrobial/antiinflammatory agents such as Bexident Post or extended duration local anesthetic agents such as liposomal bupivacaine placed directly in or in the vicinity of the extraction socket.

Abstract
BACKGROUND In this article, the authors examine the available scientific evidence regarding adverse effects of short-term use of nonsteroidal anti-inflammatory drugs (NSAIDs). Short-term use was defined as 10 days or fewer. METHODS The authors reviewed randomized controlled clinical trials and cohort and case-controlled clinical studies published between 2001 and June 2015 in which the investigators reported on the safety of nonselective cyclooxygenase inhibitors and of cyclooxygenase-2 selective inhibitor NSAIDs. RESULTS The systematic review process according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines allowed the authors to identify 40 studies that met the inclusion criteria. CONCLUSIONS On the basis of the available scientific evidence, NSAIDs may be considered relatively safe drugs when prescribed at the most effective dose and for the shortest duration of time, which was defined to be 10 days or fewer. PRACTICAL IMPLICATIONS Although the US Food and Drug Administration recommends the use of NSAIDs beyond 10 days to be accompanied by a consultation with a health care provider, the use of NSAIDs may be considered relatively safe when prescribed at the most effective dose and for the shortest duration of time, which was defined as 10 days or fewer. Exceptions would be for patients at risk of developing NSAID-exacerbated respiratory disease, patients with prior myocardial infarction who are receiving antithrombotic therapy, patients with asthma, and patients with a history of renal disease.

Abstract
BACKGROUND Effective and safe drug therapy for the management of acute postoperative pain has relied on orally administered analgesics such as ibuprofen, naproxen and acetaminophen, or N-acetyl-p-aminophenol (APAP), as well as combination formulations containing opioids such as hydrocodone with APAP. The combination of ibuprofen and APAP has been advocated in the last few years as an alternative therapy for postoperative pain management. The authors conducted a critical analysis to evaluate the scientific evidence for using the ibuprofen-APAP combination and propose clinical treatment recommendations for its use in managing acute postoperative pain in dentistry. TYPES OF STUDIES REVIEWED The authors used quantitative evidence-based reviews published by the Cochrane Collaboration to determine the relative analgesic efficacy and safety of combining ibuprofen and APAP. They found additional articles by searching the Ovid MEDLINE, PubMed and ClinicalTrials.gov databases. CONCLUSIONS The results of the quantitative systematic reviews indicated that the ibuprofen-APAP combination may be a more effective analgesic, with fewer untoward effects, than are many of the currently available opioid-containing formulations. In addition, the authors found several randomized controlled trials that also indicated that the ibuprofen-APAP combination provided greater pain relief than did ibuprofen or APAP alone after third-molar extractions. The adverse effects associated with the combination were similar to those of the individual component drugs. Practical Implications. Combining ibuprofen with APAP provides dentists with an additional therapeutic strategy for managing acute postoperative dental pain. This combination has been reported to provide greater analgesia without significantly increasing the adverse effects that often are associated with opioid-containing analgesic combinations. When making stepwise recommendations for the management of acute postoperative dental pain, dentists should consider including ibuprofen-APAP combination therapy.

Efficacy and safety of additional 200-mg dose of celecoxib in adult patients with postoperative pain following extraction of impacted third mandibular molar: a multicenter, randomized, double-blind, placebo-controlled, phase II study in Japan. Clin Ther 2012; 34:314-28. [PMID: 22284900 DOI: 10.1016/j.clinthera.2012.01.004] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2011] [Revised: 01/03/2012] [Accepted: 01/04/2012] [Indexed: 11/28/2022]
Abstract
BACKGROUND Although third mandibular molar extraction is a widely used and validated model of acute pain for evaluating analgesic efficacy, a large proportion of patients experience moderate or severe pain following this procedure and require analgesia. Current treatment options have been associated with safety concerns and alternative therapies are sought. OBJECTIVE Our aim was to assess the efficacy and safety of an additional 200-mg dose of celecoxib, administered 5 to 12 hours after an initial 400-mg dose of the drug for the treatment of moderate or severe acute pain following extraction of an impacted third mandibular molar. METHODS This was a multicenter, randomized, double-blind, placebo-controlled, Phase II study. Patients experiencing moderate or severe pain within 1 to 2 hours following extraction of an impacted third mandibular molar received an initial 400-mg dose of celecoxib. Patients requiring additional analgesia were subsequently randomized to receive either an additional 200-mg dose of celecoxib or placebo 5 to 12 hours after the initial dose. The study was designed and conducted by Pfizer Inc. for approval of celecoxib in Japan for the indication of acute pain. The primary end point was the patient's impression of efficacy (4-category global evaluation scale). Secondary efficacy end points included pain intensity on a 4-category pain intensity scale, pain intensity on a 100-mm visual analog scale (VAS), and the pain intensity difference (100-mm VAS). In an exploratory analysis, use of rescue medication was evaluated. Primary and secondary end points were analyzed using the full analysis set. Assessment of the safety profile included a physical examination, measurement of pulse rate and blood pressure, standard 12-lead ECG, and laboratory tests. RESULTS A total of 69 patients (celecoxib, 42/64 [65.6%]; placebo, 27/58 [46.6%]) received the additional dose of study medication; all completed the study without the need for rescue medication. A significantly higher proportion of patients in the celecoxib 200 mg group (41/64 [64.1%]) compared with the placebo group (15/58 [25.9%]) rated the study medication as "good" or "excellent" ≥ 2 hours after the additional dose (P < 0.0001). Pain intensity (VAS) 2 hours after the additional dose was significantly higher in the placebo group than in the celecoxib 200 mg group (P = 0.0003). The reduction in pain intensity from baseline to 2 hours after the additional dose of study medication was also significantly greater in the celecoxib 200 mg group than in the placebo group (P < 0.0001). The incidence of treatment-related, all-cause adverse events was slightly lower in patients receiving celecoxib 200 mg (20.3%) compared with placebo (31.0%). CONCLUSIONS Overall, an additional 200-mg dose of celecoxib was well tolerated and efficacious in reducing the pain associated with extraction of an impacted third mandibular molar in the study population.

Abstract
BACKGROUND Opioids are analgesics that have potential for misuse, abuse or addiction. Up to an estimated 23 percent of prescribed doses are used nonmedically. As prescribers of 12 percent of immediate-release (IR) opioids in the United States, dentists can minimize the potential for misuse or abuse. METHODS The authors participated in a two-day meeting in March 2010 cohosted by Tufts Health Care Institute Program on Opioid Risk Management, Boston, and Tufts University School of Dental Medicine, Boston. The purpose of the meeting was to synthesize available opioid abuse literature and data from a 2010 survey regarding West Virginia dentists' analgesic prescribing practices, identify dentists' roles in prescribing opioids that are used nonmedically, highlight practices that dentists can implement and identify research gaps. RESULTS Dentists can play a role in minimizing opioid abuse through patient education, careful patient assessment and referral for substance abuse treatment when indicated, and using tools such as prescription monitoring programs. Research is needed to determine the optimal number of doses needed to treat dental-related pain. CONCLUSIONS Dentists cannot assume that their prescribing of opioids does not affect the opioid abuse problem in the United States. The authors suggest that dentists, along with other prescribers, take steps to identify problems and minimize prescription opioid abuse through greater prescriber and patient education; use of peer-reviewed recommendations for analgesia; and, when indicated, the tailoring of the appropriate and legitimate prescribing of opioids to adequately treat pain. Practice Implications. The authors encourage dentists to incorporate practical safeguards when prescribing opioids, consistently educate patients about how to secure unused opioids properly, screen patients for substance use disorders and develop a referral network for the treatment of substance use disorders.

Abstract
BACKGROUND Single-photon emission computed tomography (SPECT) has been employed in the study of altered regional cerebral blood flow (CBF) in experimental and chronic pain. CBF patterns have not been evaluated in patients with acute postoperative pain. OBJECTIVE The purpose of this pilot study was to employ SPECT to measure CBF distribution associated with postoperative dental pain and to compare these CBF patterns to subsequent images in the same patients who were experiencing pain relief versus continued or worsening pain who had received active or placebo analgesic interventions. The primary outcome measure was the percentage change in blood flow in various regions of interest. METHODS Twenty-two healthy individuals (10 males and 12 females, age range 20-29 years) who underwent the removal of ≥1 partial or full bony impacted mandibular third molars were evaluated for pain intensity as the local anesthesia dissipated, employing a 0 to10 numeric rating scale (0 = no pain; 10 = worst imaginable). When the subjects' pain level reached ≥4/10, they were injected intravenously with 260 MBq of technetium Tc 99m bicisate (ethyl cysteinate dimer). Under double-blind conditions and 10 minutes before being placed in the SPECT scanner, the first 10 subjects were randomized to receive intravenous ketorolac 15 mg or saline while the remaining 12 subjects were randomized to receive by mouth either ibuprofen 400 mg, ibuprofen 200 mg, acetaminophen 1000 mg, or placebo. One hour after drug administration, subjects were reevaluated for pain, injected with 925 MBq of technetium Tc 99m bicisate, given rescue medication if required, and then rescanned. CBF ratios were obtained for regions of interest and by normalizing to average whole brain activity. RESULTS Subjects generally had a moderate degree (mean [SD], 7.3% [4.0%]) of thalamic asymmetry on initial scans with pain; after treatment, subjects reporting worsening pain regardless of the intervention had higher thalamic asymmetry (8.1% vs 2.8%) than those reporting relief of pain. Subjects who reported reduced pain after the intervention had significantly different (P < 0.05) mean CBF changes compared with those reporting worsening pain in the left prefrontal cortex, left sensorimotor area, right anterior cingulate, and right caudate. CONCLUSIONS Acute postoperative dental pain was associated with moderate thalamic asymmetry that improved following successful pain management. Sustained or worsening pain was associated with increased CBF in brain regions associated with pain pathways, whereas pain relief was associated with decreased activity in the same areas.

Abstract
SCIO-469 is a selective p38α mitogen-activated protein kinase (MAPK) inhibitor for preclinical models of acute pain. This prospective, double-blind, randomized clinical study compared efficacy and safety of oral SCIO-469, ibuprofen, and placebo in postsurgical dental pain. Subjects (n = 263) undergoing extraction of 1 or more impacted mandibular third molars received preoperative treatment with SCIO-469 (150, 210, or 300 mg), ibuprofen (400 mg), or placebo; the 210-mg group received 90 mg postoperatively. A 4-point categorical scale and a 100-mm visual analogue scale were used to measure pain intensity. The primary end point was median time from first incision to first rescue medication using the Kaplan-Meier product limit estimator. All SCIO-469 groups had significantly longer times to rescue medication compared with placebo; preoperative and postoperative treatment with 210 + 90 mg SCIO-469 resulted in 8.1 hours versus 4.1 hours to rescue for placebo (P = .003). Ibuprofen also increased time to rescue medication (6.6 hours) versus placebo (P = .04). Dizziness, headache, and nausea were the most frequently reported adverse events. This is the first clinical demonstration of antinociceptive effects in acute pain with preoperative administration of a p38α MAPK inhibitor.

Abstract
BACKGROUND This review updates a 1999 Cochrane review showing that ibuprofen at various doses was effective in postoperative pain in single dose studies designed to demonstrate analgesic efficacy. New studies have since been published. Ibuprofen is one of the most widely used non-steroidal anti-inflammatory (NSAID) analgesics both by prescription and as an over-the-counter medicine. Ibuprofen is used for acute and chronic painful conditions. OBJECTIVES To assess analgesic efficacy of ibuprofen in single oral doses for moderate and severe postoperative pain in adults. SEARCH STRATEGY We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to May 2009. SELECTION CRITERIA Randomised, double blind, placebo-controlled trials of single dose orally administered ibuprofen (any formulation) in adults with moderate to severe acute postoperative pain. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. Pain relief or pain intensity data were extracted and converted into the dichotomous outcome of number of participants with at least 50% pain relief over 4 to 6 hours, from which relative risk and number-needed-to-treat-to-benefit (NNT) were calculated. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals were collected. MAIN RESULTS Seventy-two studies compared ibuprofen and placebo (9186 participants). Studies were predominantly of high reporting quality, and the bulk of the information concerned ibuprofen 200 mg and 400 mg. For at least 50% pain relief compared with placebo the NNT for ibuprofen 200 mg (2690 participants) was 2.7 (2.5 to 3.0) and for ibuprofen 400 mg (6475 participants) it was 2.5 (2.4 to 2.6). The proportion with at least 50% pain relief was 46% with 200 mg and 54% with 400 mg. Remedication within 6 hours was less frequent with higher doses, with 48% remedicating with 200 mg and 42% with 400 mg. The median time to remedication was 4.7 hours with 200 mg and 5.4 hours with 400 mg. Sensitivity analysis indicated that pain model and ibuprofen formulation may both affect the result, with dental impaction models and soluble ibuprofen salts producing better efficacy estimates. Adverse events were uncommon, and not different from placebo. AUTHORS' CONCLUSIONS The very substantial amount of high quality evidence demonstrates that ibuprofen is an effective analgesic in treating postoperative pain. NNTs for 200 mg and 400 mg ibuprofen did not change significantly from the previous review even when a substantial amount of new information was added. New information is provided on remedication.

Abstract
Gap junctions play an important role in brain physiology. They synchronize neuronal activity and connect glial cells participating in the regulation of brain metabolism and homeostasis. Gap junction blockers (GJBs) include various chemicals that impair gap junction communication, disrupt oscillatory neuronal activity over a wide range of frequencies, and decrease epileptic discharges. The behavioural and clinical effects of GJBs suggest that gap junctions can be involved in the regulation of locomotor activity, arousal, memory, and breathing. Severe neuropsychiatric side effects suggest the involvement of gap junctions in mechanisms of consciousness. Unfortunately, the available GJBs are not selective and can bind to targets other than gap junctions. Other problems in behavioural studies include the possible adverse effects of GJBs, for example, retinal toxicity and hearing disturbances, changes in blood-brain transport, and the metabolism of other drugs. Therefore, it is necessary to design experiments properly to avoid false, misleading or uninterpretable results. We review the pharmacological properties and electrophysiological, behavioural and cognitive effects of the available gap junction blockers, such as carbenoxolone, glycyrrhetinic acid, quinine, quinidine, mefloquine, heptanol, octanol, anandamide, fenamates, 2-APB, several anaesthetics, retinoic acid, oleamide, spermine, aminosulfonates, and sodium propionate. It is concluded that despite a number of different problems, the currently used gap junction blockers could be useful tools in pharmacology and neuroscience.

Abstract
BACKGROUND AND OBJECTIVES Surgical extraction of an impacted third molar is generally followed by acute post-operative pain that has been shown to be primarily inflammatory. Thus, use of NSAIDs in this context is appropriate and has been shown to be effective. Several drugs are employed for this purpose, but no information exists on the reasons why preference is given to one rather than another. The principal objective of this study was to evaluate the pattern of administration of NSAIDs in patients undergoing surgery for impacted third molar extraction. The study also aimed to collect information on the efficacy, onset and duration of the analgesic effect of routinely prescribed NSAIDs and to assess the duration of treatment with these drugs and their tolerability. METHODS This was an observational, multicentre, prospective survey. A total of 616 patients (38% male and 62% female) from the Italian Stomatology Clinics of the Universities of Bologna, Brescia, Cagliari, Chieti, Pavia, Pisa, Siena and Varese and from the Department of Oral and Maxillo-Facial Surgery of Semmelweis University, Budapest, were eligible for the study. Patients were evaluated over the 7 days following surgical extraction. NSAIDs were prescribed according to the normal prescribing habits of the centre and physician involved. The main outcomes of interest in the survey were the efficacy, onset and duration of analgesic effect, duration of therapy, and tolerability of the NSAIDs prescribed. RESULTS Nimesulide was the most prescribed NSAID (68%), followed by diclofenac, ketoprofen and ibuprofen. Because of the low proportion of patients receiving other NSAIDs, these patients were considered a single treatment group for evaluation purposes. Nimesulide, especially when given before patients started experiencing pain after surgery, was more effective than other NSAIDs in reducing the severity of pain on the day of surgery, in delaying the time to maximum intensity of pain, in providing complete pain relief and in prolonging the duration of analgesic effect on the day of surgery. These results are consistent with the known anti-inflammatory and analgesic actions of nimesulide and with the important role of inflammation in the onset of pain after this type of surgery. CONCLUSION These results confirm nimesulide as an effective reference drug for the treatment of post-operative dental pain and show that it has a positive benefit/risk profile in this setting.

Abstract
OBJECTIVE Tapentadol is a new, centrally acting analgesic with two mechanisms of action, combining μ-opioid agonism and norepinephrine reuptake inhibition in a single molecule. This study assessed tapentadol immediate release (IR) in patients with postsurgical orthopedic pain. METHODS This randomized, double-blind, phase II study involved patients with moderate-to-severe pain after bunionectomy surgery (first metatarsal with osteotomy). Patients (N = 269) were randomly assigned to receive tapentadol IR 50 or 100 mg, oxycodone HCl IR 10 mg, or placebo; the study drug was taken every 4-6 h, over a 72-h period starting 1 day after surgery (Evaluation Day 2). The primary endpoint was the sum of pain intensity over 24 h (SPI-24) on the second day after randomization (Evaluation Day 3). Potential limitations of this study included the use of rescue medication and the fact that it was not powered to statistically compare between-group differences in tolerability measures. RESULTS Mean (standard deviation [SD]) SPI-24 values on Evaluation Day 3 were significantly lower for tapentadol IR (50 mg: 33.6 [19.7], p = 0.0133; 100 mg: 29.2 [15.2], p = 0.0001) and oxycodone HCl IR 10 mg (35.7 [17.2]; nominal p = 0.0365) compared with placebo (41.9 [17.7]). The most common treatment-emergent adverse events for all treatment groups were characteristic of drugs with μ-opioid agonist activity. While providing similar analgesic efficacy, tapentadol IR 50 mg was associated with lower rates of nausea (46.3% vs. 71.6% for oxycodone HCl IR 10 mg), dizziness (32.8% vs. 56.7%), vomiting (16.4% vs. 38.8%), and constipation (6.0% vs. 17.9%), and a similar rate of somnolence (28.4% vs. 26.9%) compared with oxycodone HCl IR 10 mg. CONCLUSIONS Tapentadol IR 50 and 100 mg and oxycodone HCl IR 10 mg were effective in this study for the relief of acute postoperative pain following bunionectomy. The study results suggest improved gastrointestinal tolerability of tapentadol IR 50 mg compared with oxycodone at a dose showing comparable efficacy.

Abstract
AIMS Establishing the dose-response relationship for clinically useful doses of aspirin, ibuprofen and paracetamol has been difficult. Indirect comparison from meta-analysis is compromised by too little information at some doses. METHODS A systematic review of randomized, double-blind trials in acute pain comparing different doses of aspirin, ibuprofen and paracetamol was therefore undertaken. RESULTS Fifty trials were found. Numerical superiority of higher over lower dose was found by the original authors in 37/50 trials (74%) and statistical superiority in 11/50 (22%). Twenty-eight trials had design, quality and data reporting characteristics to allow pooling of common doses; in 3/28 (11%) of the individual trials our calculations showed statistical superiority of higher over lower dose. Pooled comparison of 1000/1200 mg aspirin over 500/600 mg was statistically superior, with a number-needed-to-treat (NNT) for higher over lower dose of 16 (8 to > 100). Pooled comparison of 400 mg ibuprofen over 200 mg was statistically superior, with an NNT for higher over lower dose of 10 (6-23). Pooled comparison of 1000 mg paracetamol over 500 mg was statistically superior, with an NNT for higher over lower dose of 9 (6-20). CONCLUSIONS Use of trials making direct comparison of two different doses of target drugs revealed the underlying dose-response curve for clinical analgesia.

Abstract
The analgesic efficacy of aceclofenac in the control of pain after surgical extraction of impacted mandibular third molars was compared with its preoperative administration. Two groups of 20 patients each were medicated with 2 tablets of 100 mg aceclofenac taken orally either 1h before surgery or in the early postoperative period. All surgeries were performed by the same surgeon and the surgical technique was the same for all patients. Pain was assessed with a Visual Analogue Scale and a 0-4 Scale, as well as by counting the number of analgesic drug tablets taken after the surgery. Patients in the preoperative group took fewer tablets postoperatively and had a lower pain score both in the Visual Analogue Scale and the 0-4 Scale. This difference, however, was statistically significant only at 6h after surgery, which is the time of maximum pain for this surgical procedure. Aceclofenac was more efficient in controlling pain when administered before the surgery.

Abstract
UNLABELLED We conducted this double-blinded, randomized study to assess the analgesic effect of repeated administrations of paracetamol, administered as propacetamol, an injectable prodrug formulation of paracetamol, and to compare this with the analgesic effects of morphine. Patients experiencing moderate to severe pain after elective surgical removal of bone-impacted third-molar teeth under general anesthesia were randomly assigned to receive IV propacetamol 2 g (n = 31), IM morphine 10 mg (n = 30), or placebo (n = 34). Five hours later, the treatments were readministered at half of the previous dosages. Standard measures of analgesia were collected repeatedly for 10 h. Propacetamol and morphine were significantly more effective than placebo in all primary measures of analgesia over 5 h after the first administration and globally over 10 h (first and second administrations). After the first dose, 21 of the 34 patients in the placebo group required rescue medication, compared with 6 of the 31 in the propacetamol group (P < 0.0009) and 4 of the 30 in the morphine group (P < 0.0001). No statistically or clinically significant differences were found between propacetamol and morphine for any sum or peak measures of analgesia. No serious adverse events were reported; adverse events were significantly less frequent in the propacetamol group than in the morphine group (P < 0.027). Propacetamol administered IV in repeated doses (2 g followed by 1 g) has a significant analgesic effect that is indistinguishable from that of morphine administered IM (10 mg followed by 5 mg) after dental surgery, with better tolerability. IMPLICATIONS After moderately painful surgical procedures, IV paracetamol, administered as propacetamol, may be an asset in the control of acute postoperative pain.

Abstract
The non-steroidal anti-inflammatory drugs (NSAIDs) are among the most widely used classes of drugs for the management of acute and chronic pain in dentistry. Their therapeutic efficacy and toxicity are well-documented and provide evidence that NSAIDs generally provide an acceptable therapeutic ratio of pain relief with fewer adverse effects than the opioid-mild analgesic combination drugs that they have largely replaced for most dental applications. The great many studies done with the oral surgery model of acute pain indicate that a single dose of an NSAID is more effective than combinations of aspirin or acetaminophen plus an opioid, with fewer side-effects, thus making it preferable for ambulatory patients. The combination of an NSAID with an opioid generally results in marginal analgesic activity but with an increased incidence of side-effects, which limits its use to patients in whom the NSAID alone results in inadequate analgesia. The selective COX-2 inhibitors hold promise for clinical efficacy with less toxicity from chronic administration and may prove advantageous for the relief of chronic orofacial pain. The use of repeated doses of NSAIDs for chronic orofacial pain should be re-evaluated in light of a lack of documented efficacy and the potential for serious gastrointestinal and renal toxicity with repeated dosing.

Abstract
Ketorolac 10 and 20 mg, ketoprofen 50 mg and placebo were compared in a multiple-dose, double-blind, randomized analgesic study that included 150 patients with pain after impacted third molar removal. Patients evaluated their study medication over a 48 h period. Bivariate and multivariate analysis revealed statistically significant differences between the different medications studied, evaluated by the consumption of rescue medication (50.4-80.4% of the placebo group required rescue versus 17.0-47.6% of the ketoprofen, 5.7-31.9% of the ketorolac 10 mg and 1.8-22.5% of the ketorolac 20 mg groups), the pain relief experienced by the patient (P<0.05), and the overall efficacy of the medication (P<0.05). The efficacy of ketorolac 10 mg did not differ from that of ketorolac 20 mg, and both were more efficacious than ketoprofen 50 mg, which in turn was more efficacious than the placebo. One-third of the placebo group did not require rescue medication. The factors with the greatest influence on the use of rescue medication were the analgesic taken by the patient and the presence or not of postoperative inflammation.

Abstract
BACKGROUND Ibuprofen liquigel is a solubilized potassium ibuprofen 200-mg gelatin capsule formulation that was approved for over-the-counter use in 1995. OBJECTIVE This study compared the analgesic efficacy and tolerability of ibuprofen liquigel 200 mg, ibuprofen liquigel 400 mg, acetaminophen caplets 1000 mg, and placebo in patients experiencing moderate or severe pain after surgical removal of impacted third molars. METHODS This randomized, double-blind, parallel-group, 6-hour study was conducted in 210 patients experiencing moderate or severe postoperative pain. Ratings of pain intensity and pain relief were recorded every 15 minutes for the first hour, at 90 and 120 minutes, and then hourly through hour 6. The onsets of first perceptible relief and meaningful relief were recorded using 2 stopwatches. An analysis of variance model was employed to test for significant differences (P < or = 0.05) between treatment groups with respect to pain relief, pain intensity difference, total pain relief (TOTPAR), and summed pain intensity difference (SPID). Stopwatch measures were analyzed using the Cox proportional hazards model. Drug tolerability was assessed by monitoring the occurrence of adverse events. RESULTS During the first 2 hours of the study (TOTPAR 2 and SPID 2), all active treatments were significantly more efficacious than placebo (P < 0.001), with ibuprofen liquigel 200 and 400 mg significantly more efficacious than acetaminophen 1000 mg (P < 0.05 and P < 0.01, respectively). For the entire duration of the study (TOTPAR 6 and SPID 6), only the 2 doses of ibuprofen liquigel were significantly more efficacious than placebo (P < 0.001). Ibuprofen liquigel 200 and 400 mg were also significantly more efficacious than acetaminophen 1000 mg on the summary measures TOTPAR 6 and SPID 6 (P < 0.01 and P < 0.001, respectively). Analysis of the stopwatch data revealed that all active treatments displayed significantly more rapid onsets to confirmed first perceptible relief (P < 0.001 to < 0.05) and meaningful relief (P < 0.001 to < 0.01) than did placebo, with ibuprofen liquigel 400 mg displaying a significantly more rapid onset to meaningful relief than acetaminophen 1000 mg (P < 0.05) and a significantly more rapid onset to confirmed first perceptible relief than acetaminophen 1000 mg (P < 0.001) and ibuprofen liquigel 200 mg (P < 0.01). All adverse events were considered mild or moderate, with an overall incidence of 11.5% in the ibuprofen liquigel 200-mg group, 6.8% in the ibuprofen liquigel 400-mg group, 19.0% in the acetaminophen 1000-mg group, and 25.9% in the placebo group. CONCLUSIONS Ibuprofen liquigel provided greater peak and overall analgesic effects and a more rapid onset to analgesia than did acetaminophen 1000 mg.

Abstract
BACKGROUND It is just 100 years since the introduction of aspirin to medicine. Since then, aspirin and its derivatives have been joined by acetaminophen, and the nonsteroidal anti-inflammatory drugs--ibuprofen, naproxen sodium, and ketoprofen--as the only over-the-counter (OTC) agents approved by the US Food and Drug Administration for the short-term treatment of pain, headache, dysmenorrhea, and fever. Recently the prescription use of aspirin has expanded to include a number of antiplatelet indications. OBJECTIVE The purpose of this paper is to review critically the history, mechanisms of action, efficacy, and tolerability of OTC analgesic and antipyretic products. Relatively new and potential future indications for these drugs are also discussed. CONCLUSION Although all of the OTC analgesic/antipyretic agents seem to share a common mechanism of prostaglandin inhibition, there are important differences in their pharmacology, efficacy, and side-effect profiles. Considering their often-unsupervised use, the risk-benefit ratio of this class of drugs has been extremely favorable. However, when used inappropriately, even these drugs pose significant risks to certain patient populations.

Abstract
Surveys show consistently that pain is not treated well. Improvement depends on knowing which treatments are the most effective. We used systematic review to compare the relative efficacy of two common analgesics, ibuprofen and diclofenac, in post-operative pain. Studies were identified by searching MEDLINE (1966 to Dec 1996), EMBASE (1980 to Jan 1997), the Cochrane Library (Aug 1996), Biological Abstracts (Jan 1985 to Dec 1996) and the Oxford Pain Relief Database (1950 to 1994). We sought randomised, controlled, single-dose comparisons of oral ibuprofen or diclofenac against placebo. Summed pain relief or pain intensity difference over 4-6 h was extracted and converted into dichotomous information yielding the number of patients with at least 50% pain relief. This was then used to calculate the relative benefit and the number-needed-to-treat for one patient to achieve at least 50% pain relief. Thirty-four reports compared ibuprofen and placebo (3591 patients), six compared diclofenac with placebo (840 patients), and there were two direct comparisons of diclofenac 50 mg and ibuprofen 400 mg (130 patients). In post-operative pain, the numbers-needed-to-treat for ibuprofen 200 mg were 3.3 (95% confidence interval 2.8-4.0) compared with placebo, for ibuprofen 400 mg 2.7 (2.5-3.0), for ibuprofen 600 mg 2.4 (1.9-3.3), for diclofenac 50 mg 2.3 (2.0-2.7) and for diclofenac 100 mg 1.8 (1.5-2.1). Direct comparisons of diclofenac 50 mg with ibuprofen 400 mg showed no significant difference between the two. Both drugs worked well. Choosing between them is an issue of dose, safety and cost.

Abstract
BACKGROUND Ibuprofen and diclofenac are two widely used non-steroidal anti-inflammatory (NSAID) analgesics. It is therefore important to know which drug should be recommended for postoperative pain relief. This review seeks to compare the relative efficacy of the two drugs, and also considers the issues of safety and cost. OBJECTIVES To assess the analgesic efficacy of ibuprofen and diclofenac in single oral doses for moderate to severe postoperative pain. SEARCH STRATEGY Randomised trials were identified by searching Medline (1966 to December 1996), Embase (1980 to January 1997), the Cochrane Library (Issue 3 1996), Biological Abstracts (January 1985 to December 1996) and the Oxford Pain Relief Database (1950 to 1994). Date of the most recent searches: July 1998. SELECTION CRITERIA The inclusion criteria used were: full journal publication, postoperative pain, postoperative oral administration, adult patients, baseline pain of moderate to severe intensity, double-blind design, and random allocation to treatment groups which compared either ibuprofen or diclofenac with placebo. DATA COLLECTION AND ANALYSIS Data were extracted by two independent reviewers, and trials were quality scored. Summed pain relief or pain intensity difference over four to six hours was extracted, and converted into dichotomous information yielding the number of patients with at least 50% pain relief. This was then used to calculate the relative benefit and the number-needed-to-treat (NNT) for one patient to achieve at least 50% pain relief. MAIN RESULTS Thirty-four trials compared ibuprofen and placebo (3,591 patients), six compared diclofenac with placebo (840 patients) and there were two direct comparisons of diclofenac 50 mg and ibuprofen 400 mg (130 patients). In postoperative pain the NNTs for ibuprofen 200 mg were 3.3 (95% confidence interval 2.8 to 4.0) compared with placebo, for ibuprofen 400 mg 2.7 (2.5 to 3.0), for ibuprofen 600 mg 2.4 (1.9 to 3.3), for diclofenac 50 mg 2.3 (2.0 to 2.7) and for diclofenac 100 mg 1.8 (1.5 to 2.1). Direct comparisons of diclofenac 50 mg with ibuprofen 400 mg showed no significant difference between the two. REVIEWER'S CONCLUSIONS Both drugs work well. Choosing between them is an issue of dose, safety and cost.

Abstract
This double-masked, parallel-group, randomized study compared the analgesic efficacy and tolerability of a single investigational 1200-mg dose of extended-release etodolac with those of a single 400-mg dose of extended-release etodolac and twice-daily doses of conventional etodolac 200 and 400 mg and placebo given 8 hours apart in 237 patients with moderate or severe postoperative pain following surgical removal of > or = 2 impacted third molars. Both doses of conventional etodolac and the 1200-mg dose of extended-release etodolac were significantly more effective on all summary analgesic measures than placebo (P < 0.05). Conventional etodolac had an onset of analgesic activity within 45 (400 mg) to 60 (200 mg) minutes and an analgesic duration of 5 to 6 hours. Extended-release etodolac 1200 mg had an onset of action within 60 minutes and an analgesic duration of 12 to 24 hours. At hours 2 and 3, conventional etodolac 400 mg was significantly more effective than the other treatments; from hours 6 through 12, extended-release etodolac 1200 mg was significantly more effective than the other treatments (both, P < 0.05). No serious adverse events were observed in this study, with an incidence of side effects in the active etodolac groups no different than that with placebo. Extended-release etodolac 1200 mg has a prolonged analgesic duration and an acceptable side-effect profile in the oral surgery pain model.

Abstract
OBJECTIVE The purpose of this study was to evaluate the analgesic efficacy and safety of five graded doses of bromfenac sodium in patients experiencing moderate to severe pain after the surgical removal of impacted third molar teeth. STUDY DESIGN The study employed a randomized, double-blind, single-dose, 8-hour, inpatient evaluation period. The treatment groups included placebo (n = 21) and bromfenac (n = 102) at dosage strengths of 5 mg (n = 21), 25 mg (n = 20), 50 mg (n = 20), 100 mg (n = 20), and 200 mg (n = 21). Patients ingested a dose of study medication when their postsurgical pain reached a moderate or severe intensity. Pain intensity and pain relief were rated at 15, 30, 60, 90, and 120 minutes and then hourly for the remaining 6 hours. Efficacy and safety variables were analyzed by means of analysis of variance and chi-squared tests where appropriate. RESULTS At all doses, bromfenac exhibited statistical superiority (p < 0.05) to placebo, with all but the 5-mg dose being significantly more efficacious for every summary analgesic measure (3- and 8-hour sum pain intensity difference and sum pain analog intensity difference, total pain relief, peak effects, sum of pain half gone, and global evaluation). Peak analgesic effects did not increase beyond those provided by the 25-mg dose of bromfenac, although both the 100- and 200-mg bromfenac doses provided a more rapid onset and a longer duration of analgesia than either the 25- or 50-mg dosage strengths. The most common side effects reported were headache, nausea, dizziness, and drowsiness; the incidence in the bromfenac group was no different from that in the placebo group. CONCLUSIONS Bromfenac is a safe and efficacious analgesic, with a threshold dose of 5 mg and a positive dose-response up to 25 mg for peak effects and 100 mg for total analgesic activity.

Abstract
The purpose of this single-dose, randomized, placebo-controlled, and double-blind study was to evaluate the analgesic dose-response relationship of 50-mg, 100-mg, 200-mg, and 400-mg doses of ibuprofen after third molar surgery. Patients were instructed to take a single dose of either placebo or 50 mg, 100 mg, 200 mg, or 400 mg of ibuprofen when the postoperative pain was moderate to severe. Acetaminophen 500 mg was used as a rescue medication. Pain intensity, pain relief, and any possible adverse events were recorded on self-administered questionnaires hourly for 6 hours after intake of study medication. If rescue medication was taken, the time of intake was registered. A total of 304 patients entered the study, and 258 complied with the protocol. A positive analgesic dose-response relationship of 50-mg, 100-mg, 200-mg, and 400-mg doses of ibuprofen was observed when evaluated by pain intensity difference, sum of pain intensity difference, pain relief, total pain relief, and survival distribution of patients not taking rescue medication. Although significant pain relief was seen after a dose of 50 mg ibuprofen, ibuprofen 400 mg provided maximum pain relief and the longest duration of analgesic effect. Mild transient adverse events were reported by 6.8% of the patients. However, there was no significant difference in frequency between the placebo and 50 mg, 100 mg, 200 mg, and 400 mg ibuprofen dose groups.

Abstract
PURPOSE This study evaluated trismus, bite force, and pressure algometry as measures of analgesic efficacy after third molar removal. PATIENTS AND METHODS Fifty-seven patients (36 females and 21 males) developed at least moderate pain after surgical removal of a mandibular third molar and were given either ibuprofen, 400 mg (n = 26), or placebo (n = 31) in a double-blind study. Pain intensity and pain relief were rated on a five-point verbal rating scale during the 4-hour study period. Recordings of trismus, bilateral pressure pain detection and tolerance thresholds, and bite force were performed before surgery, at medication, and hourly for 4 hours. Changes in the functional variables were calculated as percent change from baseline (before surgery). RESULTS The pain intensity and pain relief ratings showed significant differences between the ibuprofen- and placebo-treated patients in the 4-hour study period. The changes in trismus, bite force, and pressure pain thresholds were in accordance with these pain ratings. Pressure pain detection threshold on the operated side was significantly lower in the placebo-treated patients compared with the ibuprofen-treated patients 2 and 3 hours after medication, whereas pressure tolerance threshold showed a significant difference after 2 hours. Bite force on the operated side was significantly less reduced 3 hours after treatment with ibuprofen when compared with placebo. CONCLUSIONS The functional measures used support the results obtained by rating of pain intensity and pain relief, and could be of value as measures of the efficacy of an analgesic to reduce functional impairment caused by postoperative pain.
