Abstract
Background Third molar surgeries are commonly performed in oral and maxillofacial surgery practice. Pain associated with this procedure is usually a frequent reason for patient apprehension and discomfort. Oral analgesics, though effective, do not provide sufficient pain relief in the immediate postoperative period. Aim To assess the postoperative effect on pain levels of single-dose administration of ketoprofen and diclofenac sodium as an injection in patients undergoing third molar removal surgeries. Methods This study was conducted among 30 patients divided into two groups (n=15). Patients in Group K received injection ketoprofen 100 mg and Group D included patients receiving injection diclofenac sodium 75 mg, both intramuscularly postoperatively. The intensity of pain was assessed at 30 minutes, two, six, and eight hours post-surgical removal of the impacted tooth using the visual analogue scale (VAS). The statistical data was analyzed using SPSS for Windows version 23.0 (IBM Corp., Armonk, NY, USA). The comparative statistical test adopted to compare pain scores between the two groups was the Independent samples t-test. A p-value of <0.05 was considered to be statistically significant. Results Our study results revealed that Group K patient's VAS scores after two hours, six hours, and eight hours were 3.9 ± 2.7, 4.5 ± 3.23, 2.93 ± 2.27 respectively. In Group D patient's VAS scores after two hours, six hours, and eight hours were 4.83 ± 2.82, 5.03 ± 2.9, 3.73 ± 2.91 respectively. Patients who were administered ketoprofen had lower pain levels when compared to patients who were given diclofenac but the difference was not statistically significant at any time point (p=0.172 after eight hours). Our results depicted that the pain levels uniformly reached their maximal levels six hours after the procedure and thereafter steadily declined in both groups. Conclusion It can be concluded from the study that both the drugs ketoprofen and diclofenac sodium analyzed in this study can be used interchangeably for the reduction of pain following lower third molar surgery.

Abstract
BACKGROUND Analgesics that contain codeine are commonly prescribed for postoperative pain, but it is unclear how they compare with nonopioid alternatives. We sought to compare the effectiveness of codeine and nonsteroidal anti-inflammatory drugs (NSAIDs) for adults who underwent outpatient surgery. METHODS We conducted a systematic review and meta-analysis of randomized controlled trials comparing codeine and NSAIDs for postoperative pain in outpatient surgery. We searched MEDLINE and Embase from inception to October 2019 for eligible studies. Our primary outcome was the patient pain score, converted to a standard 10-point intensity scale. Our secondary outcomes were patient-reported global assessments and adverse effects. We used random-effects models and grading of recommendations assessment, development and evaluation (GRADE) to assess the quality of evidence. RESULTS Forty studies, including 102 trial arms and 5116 patients, met inclusion criteria. The studies had low risk of bias and low-to-moderate heterogeneity. Compared with codeine, NSAIDs were associated with better pain scores at 6 hours (weighted mean difference [WMD] 0.93 points, 95% confidence interval [CI] 0.71 to 1.15) and at 12 hours (WMD 0.79, 95% CI 0.38 to 1.19). Stronger NSAID superiority at 6 hours was observed among trials where acetaminophen was coadministered at equivalent doses between groups (WMD 1.18, 95% CI 0.87 to 1.48). NSAIDs were associated with better global assessments at 6 hours (WMD -0.88, 95% CI -1.04 to -0.72) and at 24 hours (WMD -0.67, 95% CI -0.95 to -0.40), and were associated with fewer adverse effects, including bleeding events. INTERPRETATION We found that adult outpatients report better pain scores, better global assessments and fewer adverse effects when their postoperative pain is treated with NSAIDs than with codeine. Clinicians across all specialties can use this information to improve both pain management and opioid stewardship.

Abstract
BACKGROUND This review is an update of "Single dose oral ketoprofen and dexketoprofen for acute postoperative pain in adults" last updated in Issue 4, 2009. Ketoprofen is a non-selective nonsteroidal anti-inflammatory drug (NSAID) used to treat acute and chronic painful conditions. Dexketoprofen is the (S)-enantiomer, which is believed to confer analgesia. Theoretically dexketoprofen is expected to provide equivalent analgesia to ketoprofen at half the dose, with a consequent reduction in gastrointestinal adverse events. 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 efficacy and safety of single dose oral ketoprofen and oral dexketoprofen compared with placebo for acute postoperative pain, using methods that permit comparison with other analgesics evaluated in the same way, and criteria of efficacy recommended by an in-depth study at the individual patient level. SEARCH METHODS For this update, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Embase from 2009 to 28 March 2017. We also searched the reference lists of retrieved studies and reviews, and two online clinical trial registries. SELECTION CRITERIA Randomised, double-blind, placebo-controlled trials of single dose orally administered ketoprofen or dexketoprofen in adults with moderate to severe acute postoperative pain. DATA COLLECTION AND ANALYSIS Two review authors independently considered studies 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) or harmful outcome (NNH) with 95% confidence intervals (CI) for ketoprofen and dexketoprofen, compared with placebo, where there were sufficient data. 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 'Summary of findings' tables. MAIN RESULTS This updated review included 24 studies; six additional studies added 1001 participants involved in comparisons of ketoprofen or dexketoprofen and placebo, with a 12% increase in participants taking ketoprofen and a 65% increase for dexketoprofen. Most participants (70%) were women. Dental studies typically involved young participants (mean age 20 to 30 years); other types of surgery involved older participants (mean age 37 to 68 years). Overall, we judged the studies at high risk of bias only for small size, which can lead to an overestimation of benefit.Ketoprofen doses ranged between 6.5 mg and 150 mg. The proportion of participants achieving at least 50% pain relief over six hours with the usual ketoprofen oral dose of 50 mg was 57%, compared to 23% with placebo, giving an NNT of 2.9 (95% CI 2.4 to 3.7) (RR 2.5, 95% CI 2.0 to 3.1; 594 participants; 8 studies; high quality evidence). Efficacy was significantly better in dental studies (NNT 1.8) than other surgery (NNT 4.2). The proportion of participants using rescue medication within six hours was lower with ketoprofen (32%) than with placebo (75%), giving a number needed to treat to prevent use of rescue medication (NNTp) of 2.3 (95% CI 1.8 to 3.1); 263 participants; 4 studies; high quality evidence). Median time to remedication estimates were poorly reported. Reports of any adverse event were similar with ketoprofen (18%) and placebo (11%) (RR 1.6, 95% CI 0.98 to 2.8; 342 participants; 5 studies; high quality evidence). No study reported any serious adverse events (very low quality evidence).Dexketoprofen doses ranged between 5 mg and 100 mg. The proportion of participants achieving at least 50% pain relief over six hours with the usual dexketoprofen oral dose of 20 mg or 25 mg was 52%, compared to 27% with placebo, giving an NNT of 4.1 (95% CI 3.3 to 5.2) (RR 2.0, 95% CI 1.6 to 2.2; 1177 participants; 8 studies; high quality evidence). Efficacy was significantly better in dental studies (NNT 2.7) than other surgery (NNT 5.7). The proportion of participants using rescue medication within six hours was lower with dexketoprofen (47%) than placebo (69%), giving an NNTp of 4.7 (95% CI 3.3 to 8.0); 445 participants; 5 studies; high quality evidence). Median time to remedication estimates were poorly reported. Reports of any adverse event were similar with dexketoprofen (14%) and placebo (10%) (RR 1.4, 95% CI 0.89 to 2.2; 536 participants, 6 studies; high quality evidence). No study reported any serious adverse events (very low quality evidence). AUTHORS' CONCLUSIONS Ketoprofen at doses of 25 mg to 100 mg is an effective analgesic in moderate to severe acute postoperative pain with an NNT for at least 50% pain relief of 2.9 with a 50 mg dose. This is similar to that of commonly used NSAIDs such as ibuprofen (NNT 2.5 for 400 mg dose) and diclofenac (NNT 2.7 for 50 mg dose). Dexketoprofen is also effective with an NNT of 4.1 in the dose range 10 mg to 25 mg. Differential efficacy between dental surgery and other types of surgery seen for both drugs is unusual. Both drugs were well tolerated in single doses.

Abstract
STUDY QUESTION Is a vaginal preparation of sildenafil citrate capable of alleviating acute menstrual pain in patients with primary dysmenorrhea (PD)? SUMMARY ANSWER A vaginal preparation of sildenafil citrate is capable of alleviating acute menstrual pain in patients with PD with no observed adverse effects. WHAT IS KNOWN ALREADY Oral preparations of nitric oxide (NO) donor drugs augment relaxant effects of NO on myometrial cells, reverse the vasoconstriction caused by prostaglandins and successfully alleviate pain, but the incidence of side effects is too high for routine clinical use. Sildenafil citrate inhibits type 5-specific phosphodiesterase (PDE5), thus preventing the degradation of cyclic guanosine monophosphate (cGMP) in the muscle and augmenting the vasodilatory effects of NO. Therefore, by inhibiting PDE5, the tissue remains relaxed and more blood can circulate through. It has been used previously in a vaginal form with no observed side effects, and it enhances endometrial blood flow. STUDY DESIGN, SIZE, DURATION A double-blind, randomized, controlled trial comparing vaginal preparation of sildenafil citrate (100 mg single dose) to a placebo in 62 PD patients at the time of painful menstruation was conducted. The primary outcome was total pain relief over 4 consecutive hours (TOPAR4) comparing sildenafil citrate to placebo, where higher TOPAR4 scores represent better pain relief. Secondary outcomes were pain relief as measured by the visual analog scale (VAS) and uterine artery pulsatility index (PI). Subjects were recruited from December 2007 to January 2011. The trial was stopped due to closeout of the funding for the study. PARTICIPANTS, SETTINGS, METHODS Participants were women in good health, were aged 18-35 years and suffered from moderate to severe PD. They were randomized to either vaginal placebo or 100 mg vaginal sildenafil citrate in a 1:1 ratio using random permuted blocks having a block size of 4. At baseline and 1, 2, 3, and 4 h post-treatment, patients were asked to provide assessment of their degree of pain using two scales: (i) pain on the 5-level ordinal scale used for TOPAR4 calculation and (ii) pain level on the VAS. The study ended 4 h after treatment initiation. MAIN RESULTS AND THE ROLE OF CHANCE Twenty-five subjects completed the study. Using the TOPAR4 score, the sildenafil citrate group had significantly better pain relief compared with the placebo group [mean (SD): 11.9 (3.2) versus 6.4 (2.1), respectively; difference in means = 5.3; 95% CI: (2.9,7.6); P < 0.001)]. On the VAS, sildenafil citrate provided better pain relief than placebo at each time point. At the 2-h time point, the PI was significantly lower in the sildenafil citrate group compared with the placebo group [mean (SD): 1.6 (0.6) versus 2.3 (0.5), respectively; difference in means = -0.7; 95% CI: (-1.2, -0.1); P = 0.01)]. LIMITATIONS, REASONS FOR CAUTION Since we did not meet our sample size due to the loss of funding and could not confirm our primary hypothesis, larger studies of longer duration, likely multi-center, are needed to confirm the findings from this study. WIDER IMPLICATIONS OF THE FINDINGS A number of medications have been investigated to improve the treatment options for PD, but most have proven unsuccessful or to have an unfavorable risk/benefit ratio. Since PD is a condition that most women suffer from and seek treatment for at some point in their lives, our study offers hope that vaginal sildenafil citrate is a safe and effective option for patients who do not desire or are unresponsive to treatments now available on the market. STUDY FUNDING/COMPETING INTERESTS Funding for this study was provided by National Institutes of Health (NIH) grants RO3 TW007438 and K24 HD01476. The authors report no relevant conflicts of interest. TRIAL REGISTRATION NUMBER NCT00123162 (Clinical trials.gov).

Abstract
BACKGROUND Codeine is an opioid metabolised to active analgesic compounds, including morphine. It is widely available by prescription, and combination drugs including low doses of codeine are commonly available without prescription. OBJECTIVES To assess the efficacy, the time to onset of analgesia, the time to use of rescue medication and any associated adverse events of single dose oral codeine in acute postoperative pain. SEARCH STRATEGY We searched CENTRAL, MEDLINE, EMBASE and PubMed to November 2009. SELECTION CRITERIA Single oral dose, randomised, double-blind, placebo-controlled trials of codeine for relief of established moderate to severe postoperative pain in adults. DATA COLLECTION AND ANALYSIS Studies were assessed for methodological quality and data independently extracted by two review authors. Summed total pain relief (TOTPAR) or pain intensity difference (SPID) over 4 to 6 hours were used to calculate the number of participants achieving at least 50% pain relief, which were used to calculate, with 95% confidence intervals, the relative benefit compared to placebo, and the number needed to treat (NNT) for one participant to experience at least 50% pain relief over 4 to 6 hours. Numbers using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Data on adverse events and withdrawals were collected. MAIN RESULTS Thirty-five studies were included (1223 participants received codeine 60 mg, 27 codeine 90 mg, and 1252 placebo). Combining all types of surgery (33 studies, 2411 participants), codeine 60 mg had an NNT of at least 50% pain relief over 4 to 6 hours of 12 (8.4 to 18) compared with placebo. At least 50% pain relief was achieved by 26% on codeine 60 mg and 17% on placebo.Following dental surgery the NNT was 21 (12 to 96) (15 studies, 1146 participants), and following other types of surgery the NNT was 6.8 (4.6 to 13) (18 studies, 1265 participants). The NNT to prevent use of rescue medication within 4 to 6 hours was 11 (6.3 to 50) (11 studies, 765 participants, mostly non-dental); the mean time to its use was 2.7 hours with codeine and 2.0 hours with placebo. More participants experienced adverse events with codeine 60 mg than placebo; the difference was not significant and none were serious. Two adverse event withdrawals occurred with placebo. AUTHORS' CONCLUSIONS Single dose codeine 60 mg provides good analgesia to few individuals, and does not compare favourably with commonly used alternatives such as paracetamol, NSAIDs and their combinations with codeine, especially after dental surgery; the large difference between dental and other surgery was unexpected. Higher doses were not evaluated.

Theoretically dexketoprofen is expected to provide equivalent analgesia to ketoprofen at half the dose, with a consequent reduction in gastrointestinal adverse events. OBJECTIVES To assess efficacy, duration of action, and associated adverse events of single dose oral ketoprofen and dexketoprofen in acute postoperative pain in adults. SEARCH STRATEGY We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to August 2009. SELECTION CRITERIA Randomised, double blind, placebo-controlled trials of single dose orally administered ketoprofen and dexketoprofen 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 was collected. MAIN RESULTS Fourteen studies compared ketoprofen (968 participants) at mainly 25 mg and 50 mg with placebo (520 participants). Seven studies compared dexketoprofen (681 participants) at mainly 10 mg to 25 mg with placebo (289 participants). Studies were of adequate reporting quality, and participants had pain following dental, orthopaedic, obstetric, gynaecological and general surgery. There was considerable clinical heterogeneity between studies in dental and other types of surgery, particularly bunionectomy, which limited analysis.Ketoprofen at doses between 12.5 mg and 100 mg produced NNTs for at least 50% pain relief over 4 to 6 hours of 2.4 to 3.3. For dental studies only there was a trend to more efficacy at higher doses, with NNT decreasing from 2.4 at 12.5 mg to 1.6 at 100 mg. Dexketoprofen at doses of 10/12.5 mg and 20/25 mg produced NNTs for at least 50% pain relief over 4 to 6 hours of 3.2 and 3.6, with no obvious dose response. Significantly fewer participants used rescue medication with ketoprofen and dexketoprofen than placebo. The median time to remedication was about 5 hours with ketoprofen and 4 hours with dexketoprofen. The expected equivalent efficacy with a half dose of dexketoprofen compared to ketoprofen was not demonstrated.Adverse events were uncommon with both drugs, and not significantly different from placebo. AUTHORS' CONCLUSIONS Ketoprofen at doses of 25 mg to 100 mg is an effective analgesic in moderate to severe acute postoperative pain with an NNT for at least 50% pain relief of 3.3 with a 50 mg dose. This is similar to that of commonly used NSAIDs such as ibuprofen (NNT 2.5 for 400 mg dose) and diclofenac (NNT 2.7 at 50 mg dose). Duration of action is about 5 hours. Dexketoprofen is also effective with NNTs of 3.2 to 3.6 in the dose range 10 mg to 25 mg. Both drugs were well tolerated in single doses.

Abstract
A randomized, double-blind, within-patient, crossover study was carried out after bilateral "identical" surgical procedures using local anesthesia only. A 3-day tablet regime of racemic ketoprofen 75 mg or acetaminophen 1000 mg qid (x 4) was given starting 3 hours after surgery. Ketoprofen reduced objectively measured swelling 27.8% (p < 0.04) better than acetaminophen 3 days after surgery and 70.8% (p < 0.02) better than acetaminophen 6 days after surgery. The pain intensity (PI) was lower after ketoprofen than after acetaminophen from 2 to 6 hours after the first drug intake (all p-values < or = 0.03). Sum PI during the first (SUMPI3.5-6, p = 0.003) and second dose intervals (SUMPI6.5-9, p = 0.007) was lower for ketoprofen than for acetaminophen but not different for the third dose interval (SUMPI9.5-11, p = 0.53). Ketoprofen was a more effective analgesic than acetaminophen on the day of surgery (SUMPI3.5-11, p = 0.005). There was no difference (p > 0.05) between the treatments with respect to mouth opening, drug preference, global evaluation, or adverse reports. Adverse reports included stomach pain and diarrhea in both treatment groups. Ketoprofen 75 mg x 4 for 3 days reduces subjectively assessed pain and objectively measured swelling (i.e., anti-inflammatory effect) following third-molar surgery.

Abstract
BACKGROUND An experience of poorly managed pain related to dental treatment can lead patients to avoid or postpone treatment. The development of new pain management strategies equips dental clinicians with additional treatment options that can provide more effective pain relief LITERATURE REVIEWED The author reviewed dental and medical literature dealing with the safety, efficacy and mechanisms of action of common analgesic treatments. CONCLUSIONS For the treatment of mild to moderate pain, acetaminophen and non-steroidal anti-inflammatory drugs, or NSAIDs, continue to be the most appropriate options. The use of cyclo-oxygenase2-inhibitor NSAIDs should be strongly considered for use with patients at risk of experiencing gastrointestinal toxicity. The pathophysiology of pain is a complex central and peripheral nervous system process, and the use of combination analgesics that act at multiple pain sites can improve pain relief after a dental procedure. For moderate to moderately severe pain, tramadol or combination medications such as tramadol with acetaminophen or codeine with acetaminophen are appropriate. For severe pain, use of opioids or opioid combinations is advised. CLINICAL IMPLICATIONS Providing appropriate treatment after dental surgery requires a careful medical history and an educated anticipation of the level of pain the patient may encounter. New analgesic options are available and should be considered, particularly combination analgesics, which can provide faster onset and prolonged duration of action and can combat pain at multiple sites of action.

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 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
This double-blind, randomized, parallel-group study compared the analgesic efficacy and safety of single doses of (R)- ketoprofen 25 mg and 100 mg to that of acetaminophen 1,000 mg and placebo in 177 patients experiencing moderate to severe pain after surgical removal of their impacted third molars. Both (R)- ketoprofen 100 mg and acetaminophen 1,000 mg were significantly (P < 0.05) more efficacious than placebo for all summary analgesic measures. Other than a more rapid analgesic onset (45 minutes versus 60 minutes) for acetaminophen 1,000 mg, (R)- ketoprofen 100 mg and acetaminophen 1,000 mg were statistically equivalent to each other. The 25 mg dose of (R)- ketoprofen appeared to approach the analgesic threshold dose, being numerically but not statistically superior to placebo for all summary measures. There were no serious adverse events observed in this study, with the overall incidence of side effects being somewhat less in the (R)- ketoprofen groups than in the acetaminophen 1,000 mg group. (R)- Ketoprofen possesses analgesic activity and an acceptable side-effect profile in the oral surgery pain model.

Abstract
Whilst treating a patient with traumatic direct carotico-cavernous fistula, pain relief was difficult to achieve. Adequate doses of ibuprofen and codeine were ineffective, but single doses of ketoprofen alleviated pain in a reproducible manner. Although similar in analgesic efficacy to codeine, and a potent inhibitor of cyclooxygenase like ibuprofen, ketoprofen has other actions which may account for the differential response seen. This observation may help elucidate the nature of local mediators involved in the pathogenesis of vascular headache pain.

Abstract
Dexketoprofen trometamol is a water-soluble salt of the dextrorotatory enantiomer of the nonsteroidal anti-inflammatory drug (NSAID) ketoprofen. Racemic ketoprofen is used as an analgesic and an anti-inflammatory agent, and is one of the most potent in vitro inhibitors of prostaglandin synthesis. This effect is due to the S(+)-enantiomer (dexketoprofen), while the R(-)-enantiomer is devoid of such activity. The pharmacokinetic profile of ketoprofen and its enantiomers was assessed in several animals species and in human volunteers. In humans, the relative bioavailability of oral dexketoprofen trometamol (12.5 and 25 mg, respectively) is similar to that of oral racemic ketoprofen (25 and 50 mg, respectively), as measured in all cases by the area under the concentration-time curve values for S(+)-ketoprofen. Dexketoprofen trometamol, given as a tablet, is rapidly absorbed, with a time to maximum plasma concentration (tmax) of between 0.25 and 0.75 hours, whereas the tmax for the S-enantiomer after the racemic drug, administered as tablets or capsules prepared with the free acid, is between 0.5 and 3 hours. Peak plasma concentrations of 1.4 and 3.1 mg/L are reached after administration of dexketoprofen trometamol 12.5 and 25 mg, respectively. From 70 to 80% of the administered dose is recovered in the urine during the first 12 hours, mainly as the acyl-glucuronoconjugated parent drug. No R(-)-ketoprofen is found in the urine after administration of dexketoprofen [S(+)-ketoprofen], confirming the absence of bioinversion of the S(+)-enantiomer in humans. in animal studies, the anti-inflammatory potency of dexketoprofen was always equivalent to that demonstrated by twice the dose of ketoprofen. Similarly, animal studies showed a high analgesic potency for dexketoprofen trometamol. The R(-)-enantiomer demonstrated a much lower potency, its analgesic action being apparent only in conditions where the metabolic bioinversion to the S(+)-enantiomer was significant. The gastric ulcerogenic effect of dexketoprofen at various oral doses (1.5 to 6 mg/kg) in the rat do not differ from those of the corresponding double doses (3 to 12 mg/kg) of racemic ketoprofen. Repeated (5-day) oral administration of dexketoprofen as the trometamol salt causes less gastric ulceration than was observed after the acid form of both dexketoprofen and the racemate. In addition, single dose dexketoprofen as the free acid at 10 to 20 mg/kg does not show a significant intestinal ulcerogenic effect in rats, while racemic ketoprofen 20 or 40 mg/kg is clearly ulcerogenic to the small intestine. The analgesic efficacy of oral dexketoprofen trometamol 10 to 20 mg is superior to that of placebo and similar to that of ibuprofen 400 mg in patients with moderate to serve pain after third molar extraction. The time to onset of pain relief appeared to be shorter in patients treated with dexketoprofen trometamol than in those treated with ibuprofen 400 mg. Dexketoprofen trometamol was well tolerated, with a reported incidence of adverse events similar to that of placebo.

Abstract
The pharmacokinetics of the enantiomers of ketoprofen after oral administration of 12.5 mg, 25 mg and 50 mg and i.v. administration of 50 mg racemic ketoprofen to 24 healthy subjects were investigated. The AUC values of R- (r2 = 0.929) and S-ketoprofen (r2 = 0.930) were proportional to dose. The absolute bioavailability of the 50 mg oral dose was 84.5 (s.d. 20.6) % and 81.4 (18.0) % for R-ketoprofen and S-ketoprofen, respectively. With the exception of AUC values no dose dependent differences in pharmacokinetic parameters were observed. However, the R-enantiomer had higher AUC, lower clearance data and higher Cmax values than the S-form after oral administration. The results suggest that stereochemical and pharmacokinetic considerations cannot explain the lack of dose response observed with ketoprofen doses below 50 mg.

Abstract
Preoperative treatment with controlled-release ketoprofen or diclofenac was compared in 56 outpatients, for control of postoperative dental pain, following unilateral or bilateral surgical removal of lower third molars. Six patients were excluded due to non-compliance, leaving 50 evaluable patients. Patients were assessed by the dental surgeon, on the day of the operation and one week later, prior to removal of sutures. Additionally, patients completed a daily diary during the postoperative week. Following surgery, scores for graded dental pain, consumption of paracetamol, incidence of dental bleeding, dysphagia, sleep disturbance and trismus were similar for the two treatment groups. However, median pain scores were consistently elevated in the diclofenac group over those seen with the ketoprofen group. The four adverse events reported were all minor and posed no problem to patient management.

Abstract
The authors challenge the general view that the analgesic effect of the nonsteroidal anti-inflammatory drugs (NSAIDs) can be universally attributed to their inhibitory effects on the synthesis of peripherally formed prostaglandins. Analgesic activity by some of these compounds in the reduction of physiological pain elicited by a single noxious stimulus, or the treatment of acute pain which results from sudden trauma to otherwise healthy tissue, is better described as an antinociceptive effect. Single-dose studies in the dental pain model that have been conducted in double-blind conditions and included a placebo control group have been reviewed; those NSAIDs which are significantly superior to the reference compound aspirin 650mg and those which could represent real alternatives to the use of narcotics in certain situations for the management of acute pain have been identified. Azapropazone, diflunisal, naproxen, oxaprozin and tolmetin are all weak inhibitors of prostaglandin synthesis, yet they have been shown to be more effective than aspirin. In a model of joint pain, azapropazone 600mg has been shown to be as effective as pethidine (meperidine) 100mg despite being the weakest inhibitor of prostaglandin synthesis. Whether the antinociceptive effect of azapropazone acts at a peripheral or a central level, or both, is not clear; evidence for the effects of NSAIDs on the central nervous system (CNS) is discussed. Historically, the antinociceptive character of some NSAIDs is apparent in several studies in both animals and humans. More recently, experimental algesimetry models designed to distinguish the antinociceptive effects of NSAIDs include the use in humans of photoplethysmography and computer-supported infrared thermographic imaging.

Abstract
One hundred sixty-one patients with postoperative pain were treated at a single center in a double-blind, randomized, parallel study designed to compare the efficacy and safety of single oral doses of ketoprofen (50 and 150 mg), an acetaminophen (650 mg) plus codeine (60 mg) combination, and placebo. From 1 through 4 hours after administration of the study drugs, the mean summed pain intensity difference (SPID) and time-weighted total pain relief (TOPAR) scores for the three active treatments generally were significantly (P less than 0.05) higher than those for placebo but not significantly different from each other. At the 6-hour evaluation, the ketoprofen groups, but not the acetaminophen-codeine group, had higher (P less than 0.05) mean SPID and TOPAR scores than the placebo group, as a result of a shorter duration of pain relief in the acetaminophen-codeine group. The 6-hour TOPAR scores were significantly (P less than 0.05) higher for both ketoprofen groups than for the acetaminophen-codeine group; the ketoprofen 150 mg group also had significantly (P less than 0.05) higher mean 6-hour SPID and global subjective assessment scores. As a result of a higher frequency of somnolence, there was a significantly (P less than 0.05) greater incidence of central nervous system adverse drug reactions among patients treated with acetaminophen plus codeine than among those treated with 150 mg of ketoprofen. These results indicate that the analgesic efficacy of both 50 and 150 mg doses of ketoprofen equals that of acetaminophen 650 mg plus codeine 60 mg and the duration of the analgesic effect of ketoprofen is significantly longer.

Abstract
The analgesic effects of single oral doses of ketoprofen 100 and 300 mg, the combination of aspirin 650 mg plus codeine 60 mg, and placebo were compared under double-blind conditions in 160 hospitalized patients with cancer pain. At baseline and at 30 minutes and hourly for 6 hours after treatment, patients evaluated their pain intensity and pain relief. The 100 mg ketoprofen dose was significantly (P less than 0.05) superior to placebo for all 14 derived efficacy parameters; the 300 mg dose was significantly superior to placebo in all assessments except derived onset of relief. Aspirin plus codeine was significantly (P less than 0.05) superior to placebo for nine of the 14 assessments. No statistically significant differences were observed among active treatments for any of the 14 derived parameters. The number of patients with a "good" response was greatest in the ketoprofen 100 mg group (55%); the numbers of good responders in the aspirin plus codeine (37.5%) and the ketoprofen 300 mg (30%) groups were comparable. The three active treatment groups were not significantly different from each other for patient response. The numbers of patients requiring rescue analgesic were significantly (P less than 0.05) lower for both ketoprofen groups, but not for the aspirin plus codeine group, as compared with the placebo group. Twenty-three percent of the 160 patients reported adverse experiences, but there were no significant differences between the treatment groups in the number or type of experience. These results show that ketoprofen is as effective and well tolerated as aspirin plus codeine in relieving cancer pain.

Abstract
Ketoprofen is a new peripherally acting analgesic and the most recently introduced nonsteroidal anti-inflammatory drug in the United States with indication for management of nonarthritic pain. Three 6-hour double-blind, single-dose, placebo-controlled studies in which patients who had undergone dental impaction surgery took ketoprofen or a comparator drug are reviewed. In the first study, ketoprofen 25, 50, and 100 mg was compared with aspirin 650 mg and placebo in 153 patients. In comparison with aspirin, significant (P less than 0.001) differences favoring ketoprofen at each dose level were found for all measures of analgesic efficacy. For the combined ketoprofen groups, 60% of the patients rated treatment as very good or excellent, compared with 16% in the aspirin group. The second study compared ketoprofen 25, 50, and 100 mg with codeine 90 mg and placebo in 129 patients. Ketoprofen appeared to have a more rapid onset, higher peak effect, and longer duration of pain relief than codeine. At least 70% of patients in each of the ketoprofen groups rated the test medication as very good or excellent, compared with only 7% of the patients in the codeine group. The third study compared ketoprofen 25 and 100 mg with ibuprofen 400 mg and placebo in 161 patients. Ketoprofen 100 mg had a faster onset of effect, the highest peak effect, and the longest duration of action over the 6-hour evaluation. Ketoprofen treatment was not associated with any unusual or serious side effects in any of the three studies.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Under double-blind, crossover conditions, 43 women with primary dysmenorrhea received ketoprofen, ibuprofen, and placebo during three consecutive menstrual cycles. Pain intensity and pain relief were determined before and for 6 hours after the loading dose (ketoprofen 150 mg, ibuprofen 800 mg) and before and 2 hours after the maintenance dose (ketoprofen 75 mg, ibuprofen 400 mg). Mean pain intensity difference and pain relief scores consistently indicated greater pain relief after the loading doses of ketoprofen and ibuprofen than after placebo. Significant (P less than 0.05) mean changes that were measured by 13 indices of analgesia after the loading doses of both ketoprofen and ibuprofen indicated greater efficacy for the active treatments than for placebo. The patients' global evaluations after the loading doses were significantly (P less than 0.05) better for the active treatments than for placebo. The efficacy results were similar after the maintenance doses. The rates of a "good" to "excellent" response were 77% for ketoprofen, 73% for ibuprofen, and 35% for placebo. Ketoprofen and ibuprofen were equally well tolerated, the most frequent adverse experiences being gastrointestinal symptoms for ketoprofen and central nervous system side effects for ibuprofen.

Abstract
The pharmacology, clinical dental studies, and the relevance to dental applications of ketoprofen, a recent addition to the group of nonsteroidal anti-inflammatory drugs, are reviewed. In addition to inhibiting the formation of prostaglandins, ketoprofen may also suppress leukotrienes and further limit inflammation. Clinically, it appears that ketoprofen compares favorably with many of the nonsteroidal drugs now in use. Recently approved for use in mild to moderate pain, ketoprofen's rapid onset of action, patent analgesic properties, and minimal side effects are particularly appealing.

Abstract
Experimental data has shown that sodium valproate has analgesic properties in animals, probably by way of the increase in cerebral and spinal gamma amino-butyric acid (GABA) it induces. A study was therefore designed to assess this analgesia in man in the postoperative period. A first open study was carried out on 12 consenting patients, who were each given 15 mg.kg-1 sodium valproate intravenously over 20 min. A significant decrease in pain intensity, measured by an analogic visual scale, was seen from the 20th min up to the 140th min. A controlled double-blind study was then carried out; it included three groups of 13 patients each. Patients in group 1 were given placebo (5% dextrose); group 2 patients were given 15 mg.kg-1 sodium valproate intravenously over 20 min, and group 3 patients 2 mg.kg-1 ketoprofen intravenously over 20 min also. There was no difference in the pain intensity profile of groups 1 and 2: sodium valproate was no more efficient than placebo in relieving postoperative pain. However, ketoprofen gave a prompt and effective analgesic effect. The clinical data obtained with sodium valproate in man during the postoperative period stand in contrast with the promising animal results. Sodium valproate cannot be recommended for the treatment of postoperative pain.

Abstract
Our purpose was to evaluate the analgesic efficacy of single oral doses of ketoprofen 25, 50, and 100 mg compared with aspirin 650 mg and placebo in the relief of moderate to severe postepisiotomy, uterine cramping, or cesarean section pain. One hundred and fifty-six patients participated in a randomized, double-blind, stratified, parallel-group study. They were observed over a six-hour period by one nurse-observer. Several of the standard summary measures of analgesia were derived from the interview data, including the sum of pain intensity differences (SPID) and the sum of the hourly relief values (TOTAL). The study showed significant differences between aspirin and placebo for four-hour SPID and several other parameters and between ketoprofen at all dose levels and placebo for the four- and six-hour SPID and many other parameters. The two higher doses of ketoprofen were significantly more effective than aspirin as as assessed by the four- and six-hour SPID, TOTAL, and other summary measures. The low dose of ketoprofen, although not significantly different from aspirin for SPID and TOTAL, showed a significantly faster onset of relief and had a better global rating. This study suggests that 50 mg of ketoprofen may be the clinical dose of choice as an analgesic. There were no adverse effects reported.
