An analgesic model for assessment of acute pain response in osteoarthritis of the knee.

BACKGROUND: Osteoarthritis (OA) is frequently treated only during periods of flare, in which rapid onset of analgesia is the outcome target. OBJECTIVE: To assess an acute pain model of knee OA in flare. METHODS: In a multicenter, randomized, double-blind, controlled study, 530 patients aged >or=50 years received valdecoxib 10 mg qd (n=212), rofecoxib 2 5 mg qd (n=208), or placebo (n=110). Pain intensity (PI) was measured on a visual analog scale (VAS) at baseline after a 10-min walk. Patients took their first dose of study medication, rested for 20 min, then measured their PI VAS at 0.5, 1, 1.5, 2, 3, 4, 5, and 6h, each time following a 10-min walk. RESULTS: PI VAS differences (PID) were significantly greater vs placebo both with valdecoxib and rofecoxib (P<0.05) beginning as early as 3h (intent-to-treat population). The percentage of patients with analgesia onset from 4h was significantly higher with both valdecoxib (55%) and rofecoxib (56%) relative to placebo (40%). Median time to first onset of analgesic was shorter with both valdecoxib and rofecoxib compared with placebo (P=0.104 vs valdecoxib; P=0.036 vs rofecoxib). CONCLUSIONS: This acute pain model of knee OA flare detected significant pain relief with agents known to relieve pain in OA and placebo within hours after the first treatment dose, allowing assessment of pain relief within hours rather than days or weeks when evaluating analgesic efficacy in OA. This model is undergoing further study to determine optimal walk times, distances, and rates to maximize its sensitivity.

Onset of analgesia for liquigel ibuprofen 400 mg, acetaminophen 1000 mg, ketoprofen 25 mg, and placebo in the treatment of postoperative dental pain.

Ibuprofen is a peripherally acting nonsteroidal anti-inflammatory drug indicated fo ranalgesia, antipyresis, and various arthritic conditions. A solubilized 200 mg liquigel formulation of ibuprofen has been shown to have a more rapid rate of absorption compared with ibuprofen 200 mg tablets. Ibuprofen liquigels have a kinetic profile similar to ibuprofen suspension, with both a higher Cmax and an earlier tmax than any solid tablet. The objective of this single-dose, double-blind, triple-dummy, parallel-group study was to assess the time to onset of relief and overall analgesic efficacy of liquigel ibuprofen 400 mg, ketoprofen 25 mg compared with acetaminophen 1000 mg, and placebo in 239 patients with moderate or severe pain following third molar extractions. Treatments were compared over 6 hours using standard scales for pain intensity and relief and stopwatch onset of meaningful relief. All active treatments provided meaningful relief significantly faster compared with placebo. Ibuprofen provided significantly faster relief compared with acetaminophen and ketoprofen. By the end of the study (6 h), onset of meaningful relief was achieved by 36%, 99%, 96%, and 88% of the patients in the placebo, ketoprofen, ibuprofen, and acetaminophen groups, respectively. The median times to onset of relief were > 6 hours for placebo, 25.5 minutes for ketoprofen, 24.2 minutes for ibuprofen, and 29.9 minutes for acetaminophen. In addition, both ibuprofen and ketoprofen showed statistical superiority over acetaminophen at earlier time points on the time-effect curves for pain relief and pain intensity difference. Consistent results were seen with respect to the 6-hour summary efficacy variables: the three active treatments were significantly better than placebo, and ibuprofen was significantly better than both acetaminophen and ketoprofen. Liquigel ibuprofen 400 mg was shown to provide faster relief and superior overall efficacy compared with ketoprofen 25 mg, acetaminophen 1000 mg, and placebo. No serious adverse effects were reported in this single-dose study.

A comparison of the newer COX-2 drugs and older nonnarcotic oral analgesics.

The newer COX-2 drugs are safer analgesics than the older NSAIDs. At the usual dose used in osteoarthritis, they have less analgesic effect than the older NSAIDs. The non-narcotic analgesics such as acetaminophen, salicylate, NSAIDs, and the newer COX-2 drugs seem to have distinctly different mechanisms of action. In limited clinical trials, some of these drugs in combination give additive analgesia. Consideration should be given to using these drugs in combination, after suitable clinical trials, to enhance the efficacy of this category of analgesics.

Analgesic efficacy of liquid ketoprofen compared to liquid dipyrone and placebo administered orally as drops in postepisiotomy pain.

OBJECTIVE: The objective of this single-center, single-dose, double-blind randomized parallel group study was to evaluate the analgesic efficacy of a new liquid formulation of ketoprofen at two dose levels (25 mg or 50 mg) compared to a commercially available liquid form of dipyrone 500 mg and placebo with all treatments administered as drops to patients with severe postepisiotomy pain. METHODS: The study was designed with a sample size of 69 patients per treatment for a total of 276 patients. However, due to administrative changes at the site, the study was prematurely terminated; thus only 108 patients (26 to 28 patients per treatment), 18 years or older, with severe postepisiotomy pain were randomized to one of the four treatments. Treatments were assessed over a 6-hour period using standard scales for pain intensity and pain relief and a number of derived variables based on these data. Since the study medications were not identical in appearance, the preparation and administration of the study medication, and the observation of the patient, were carried out by two different individuals to maintain double-blind conditions. RESULTS: All active treatments were significantly superior to placebo for several measures of analgesia including 4-hour and 6-hour SPID and TOTPAR scores. The global rating was assessed as "good" or "excellent" by over 75% of the patients in the active treatment groups compared to 7.4% of the patients in the placebo group. Reduction in pain intensity was very similar for the two-dose levels of ketoprofen and the comparator dipyrone 500 mg. CONCLUSION: Ketoprofen 25 mg or 50 mg, and dipyrone 500 mg seem to be equally suited for use as pain relief medication after minor surgery, as well as episiotomy. This study did not demonstrate a need for more than 25 mg of ketoprofen in postepisiotomy pain. All treatments were well tolerated. No adverse events were reported.

A food interaction study of bromfenac, naproxen sodium, and placebo in cesarean section patients.

Objective: This double-blind study was to compare the effect of food on the analgesic response to bromfenac, naproxen sodium, and placebo.Methods: Single doses of bromfenac (BRO) 25 mg, naproxen Na (NAP) 550 mg, or placebo (PLA) were given to 284 patients with moderate or severe pain following cesarean section. A standard breakfast was provided for the "fed" patients. "Fasted" patients received no food 3 h before and 1 h after the dose. Treatments were compared over 8 h using standard scales for pain intensity and pain relief. Plasma levels of BRO were measured in 7 fasted and 12 fed patients.Results: BRO and NAP were significantly superior to PLA; food did not affect the response to any treatment: As expected, mean peak plasma levels of bromfenac were reduced by food by about 65%.Conclusion: Food reduces the bioavailability of bromfenac but has no effect on the analgesic response.

Onset and duration of analgesia for low-dose ketoprofen in the treatment of postoperative dental pain.

The objective of this single dose, double-blind study was to determine the relative analgesic efficacy of low-dose ketoprofen (6.25 mg, 12.5 mg, and 25 mg) compared with ibuprofen (200 mg) and placebo in 175 patients with moderate to severe postoperative pain secondary to extraction of impacted third molars. Analgesia was measured during the 6-hour period after administration based on onset of relief, hourly and summary variables, and duration of treatment effect. All active treatments were significantly more effective than placebo for many hourly measures and for the summary measures sum of pain intensity differences (SPID), sum of hourly pain relief values (TOTPAR), time to peak pain relief, and patient global assessment of study medication. The three ketoprofen doses were significantly more effective than placebo beginning at 30 minutes, whereas ibuprofen was significantly better than placebo beginning at 1 hour. A dose-response relationship was observed for ketoprofen, with the two higher doses providing significantly greater analgesia than the lower dose. However, a plateau effect was seen between the 12.5-mg and 25-mg dose levels. A significantly greater proportion of patients treated with each of the active treatments (ranging from 0.83 to 0.88) reported onset of relief compared with placebo (0.20). The distribution functions of onset of relief differed significantly among treatments, with ketoprofen 12.5 mg and 25 mg having a faster onset than ibuprofen 200 mg and ketoprofen 6.25 mg. The duration of effect was generally shorter for ketoprofen than for ibuprofen, and these difference were significant. This study provides evidence that at the dose levels of 12.5 mg and 25 mg, ketoprofen is an effective analgesic in providing relief of postoperative dental pain. Ketoprofen 12.5 mg and 25 mg provide significantly greater relief in the earlier time period, with a faster onset and shorter duration of effect than ibuprofen 200 mg. The two higher doses of ketoprofen provided similar analgesia, and no additional benefit was obtained by increasing the dose of ketoprofen to 25 mg. Therefore, we conclude that ketoprofen 12.5 mg is an appropriate dose for over-the-counter use.

Analgesic efficacy of a hydrocodone with ibuprofen combination compared with ibuprofen alone for the treatment of acute postoperative pain.

Hydrocodone is a semisynthetic opioid with analgesic and antitussive properties qualitatively similar to other opioid agonists. Ibuprofen is a nonsteroidal antiinflammatory agent with analgesic and antipyretic activity and is an effective, primarily peripheral-acting antiinflammatory analgesic. The objective of this clinical trial was to determine the additive analgesic effect of the combination of 15 mg hydrocodone bitartrate with 400 mg ibuprofen, relative to 400 mg ibuprofen alone and placebo, in the treatment of postoperative pain. The single-dose analgesic efficacy of the combination of hydrocodone bitartrate with ibuprofen was compared with ibuprofen alone and placebo in 120 patients with moderate or severe postoperative pain after abdominal surgery. Analgesia was measured during the 6-hour period after dosing based on onset of relief, hourly and summary variables, and duration of effect. A significantly greater proportion of patients treated with the hydrocodone/ibuprofen combination reported onset of relief compared with ibuprofen or placebo; however, the distribution functions for time to onset of relief did not differ among treatments. Hydrocodone with ibuprofen and ibuprofen alone were significantly more effective than placebo for all measures of analgesia. The combination of hydrocodone with ibuprofen was significantly superior to ibuprofen for all hourly analgesic evaluations, weighted sum of pain intensity differences (SPID), total pain relief (TOTPAR), and global rating of study medication. No patients in the hydrocodone with ibuprofen group required analgesic remedication during the 6-hour study period, compared with 25% and 82% in the ibuprofen and placebo groups, respectively. The analgesic superiority of 15 mg hydrocodone bitartrate combined with 400 mg ibuprofen compared with 400 mg ibuprofen alone was demonstrated across many efficacy variables.

Analgesic efficacy of controlled-release oxycodone in postoperative pain.

The efficacy and safety of graded doses (10, 20, and 30 mg) of controlled-release (CR) oxycodone was compared with that of immediate-release (IR) oxycodone (15 mg), immediate-release oxycodone 10 mg in combination with acetaminophen 650 mg (APAP), and placebo in a single-dose, double-blind, randomized, parallel-group study. The participants, 182 inpatients experiencing moderate to severe pain after abdominal or gynecologic surgery, provided hourly ratings of pain intensity and relief for 12 hours after administration. All active treatments were significantly superior to placebo for many hourly measurements and for the sum of pain intensity differences (SPID) and total pain relief (TOTPAR). A dose response was found among the three levels of CR oxycodone for pain relief and peak pain intensity difference (PID), with the 20- and 30-mg doses being significantly better than the 10-mg dose. For all active treatments, peak PID and peak pain relief occurred approximately 2 to 4 hours after administration. The median time to onset of relief was 32 minutes for oxycodone plus APAP, 41 minutes for IR oxycodone, and 46 minutes for CR oxycodone 30 mg. Duration of pain relief showed that the 10-, 20-, and 30-mg doses of CR oxycodone had durations of action of 10 to 12 hours compared with IR oxycodone and oxycodone plus APAP (both approximately 7 hours). Typical adverse events, particularly somnolence, occurred in all active treatment groups. Treatment with CR oxycodone was safe and effective in this study, and its characteristics will be beneficial in the treatment of pain.

New clinical experience with tramadol.

The analgesic efficacy of tramadol has been recently reassessed as part of a new clinical development programme to support an application for registration in the USA. This article reviews the results of single dose and short term studies of oral tramadol 50, 75, 100 and 150 mg in various acute pain conditions. In a double-blind single dose study conducted in 161 patients with severe pain following caesarean section, tramadol 75 and 150 mg and the combination of paracetamol 650 mg with dextropropoxyphene napsylate 100 mg were shown to be effective and statistically superior to placebo. The results from this and 17 other similar studies in patients with pain after surgery (n = 1594) or dental extraction (n = 1859) including other comparators were included in a pooled analysis. Tramadol 100 mg was the optimal single dose for acute pain and tramadol 50 mg showed similar analgesic efficacy to codeine 60 mg. Multiple dose short term studies (n = 520) with tramadol 50, 75 and 100 mg demonstrated a statistically significant and dose-dependent reduction in the consumption of either ibuprofen or morphine as escape medication. New pharmacokinetic data show that steady-state plasma tramadol concentrations reached after oral administration of 50 mg doses every 6 hours are similar to those obtained after administration of a 100 mg single oral dose (250 micrograms/L). This rationale is supported by the results of long term studies in which the average daily dose of tramadol was approximately 250 mg.

Ketoprofen, acetaminophen plus oxycodone, and acetaminophen in the relief of postoperative pain.

Ketoprofen (Orudis) is a nonsteroidal anti-inflammatory drug that is currently approved in the United States for the management of mild to moderate pain. The objective of this trial was to determine the effectiveness of orally administered ketoprofen in the management of severe postoperative pain. This randomized, double-blind parallel study compared the efficacy and safety of single doses of 100 mg or 50 mg ketoprofen, the combination of 650 mg acetaminophen plus 10 mg oxycodone hydrochloride, 650 mg acetaminophen, or placebo in 240 patients with severe postoperative pain after cesarean section. Analgesia for the first dose was assessed over an 8-hour period. Multiple doses of 100 mg or 50 mg ketoprofen and the combination at half the dose (325 mg acetaminophen plus 5 mg oxycodone) were also assessed for up to 7 days. The 100 and 50 mg doses of ketoprofen and the combination were statistically superior to acetaminophen and placebo for many analgesic measures. A dose response was observed between the two doses of ketoprofen, with the 100 mg dose providing significantly greater analgesia over the lower dose. Ketoprofen, 100 mg, was at least as effective as the combination and its effects lasted longer, with the exception of hour 1 when the combination was superior. Remedication time for the group receiving 100 mg ketoprofen was significantly longer than for the other treatment groups. Significantly more patients who took repeated doses of the combination (84%) than those who took either dose of ketoprofen (70%) had adverse effects. Ketoprofen at both dose levels was shown to be effective, long-lasting, and well tolerated, and it should be considered as a viable option for the management of moderate to severe postoperative pain.

Analgesic oral efficacy of tramadol hydrochloride in postoperative pain.

Tramadol hydrochloride is a synthetic opiate agonist with a plasma elimination half-life of 5 to 6 hours and peak plasma levels at about 1 1/2 hours. It derives its activity from attachment to the mu-receptor and blockage of norepinephrine reuptake. The purpose of this single-dose, double-blind, placebo-controlled study was to determine the analgesic effectiveness of an oral administration of two dose levels of tramadol hydrochloride (75 or 150 mg) compared with the combination of 650 mg acetaminophen plus 100 mg propoxyphene napsylate in 161 patients with severe postoperative pain after cesarean section. Analgesia was assessed over a 6-hour period. Treatments were compared on the basis of standard scales for pain intensity and relief and a number of derived variables based on these data. A global rating of the study medication was also used to compare treatments. The three active treatments were effective analgesics, statistically superior to placebo for many hourly and summary measures. A dose response was seen between the two tramadol doses, with the 150 mg dose providing significantly greater analgesia over the lower dose. The 75 mg dose of tramadol was generally more effective than the acetaminophen-propoxyphene combination after hour 2, and significantly so for some hourly time points, as well as for the global rating of the medication. The 150 mg dose of tramadol was significantly more effective than the acetaminophen-propoxyphene combination from hour 2 through hour 6 for the sum of pain intensity differences and total pain relief scores, as well as for the global rating of the medication. Tramadol hydrochloride at both dose levels is an effective analgesic agent and at 150 mg is statistically superior to the acetaminophen-propoxyphene combination. No serious adverse effects were observed; however, dizziness was more frequently reported with 150 mg tramadol.

Meptazinol and morphine in postoperative pain assessed with a new method for onset and duration.

Meptazinol, m-(3-ethyl-1-methyl-hexahydro-1-H-azepin-3-yl) phenol hydrochloride is a centrally active opioid analgesic with a specificity for the mu-1 receptor. It has been reported to lack many of the side effects commonly observed with morphine and morphinelike drugs in man. The objective of this study was to assess the analgesic efficacy and safety of meptazinol (50 mg and 100 mg) relative to morphine (5 mg and 10 mg) when administered intramuscularly for the treatment of postoperative pain. In addition, a new clinical method for measuring onset and duration and a statistical technique for evaluating the study data are presented. One hundred and seventeen patients were evaluated for 6 hours in a randomized double blind, single dose, parallel-groups trial. Estimates of relative potency for hourly pain and relief parameters, and the summary variables sum of pain intensity differences (SPID) and total pain relief (TOTPAR) were performed. The estimate of relative potency of meptazinol to morphine for pain relief was 0.19 at 1/2 hour (i.e. 100 mg of meptazinol was approximately equivalent to 20 mg of morphine). Thereafter, there was a rapid decline of efficacy for meptazinol, with a relative potency estimate of 0.12 at 1 hour and 0.06 at 2 hours. The distribution functions for several time related events were estimated including time to onset, duration and time to remedication. The two drugs had approximately equal onset, but meptazinol had significantly shorter duration. More patients on meptazinol required remedication with a rescue analgesic and at an earlier time than patients on morphine.(ABSTRACT TRUNCATED AT 250 WORDS)

Augmentation of acetaminophen analgesia by the antihistamine phenyltoloxamine.

A double-blind, placebo-controlled, parallel-group study was performed to compare the analgesic activity of the combination of 650 mg acetaminophen plus 60 mg phenyltoloxamine citrate with that of 650 mg acetaminophen alone. Two hundred female inpatients who had severe pain associated with a recent episiotomy procedure were randomly assigned to receive a single dose of one of the two active treatments or a placebo. Analgesia was assessed over a 6-hour period. Treatments were compared on the basis of standard subjective scales for pain intensity and relief, a number of derived variables based on these data and two global measures. For essentially all measures, the two active treatments were significantly superior to the placebo control. The combination was significantly superior to acetaminophen alone for all analgesic measures including SPID, TOTAL, and global ratings. The results of this study demonstrate that 60 mg phenyltoloxamine produces significant augmentation of the analgesic activity of 650 mg acetaminophen in postepisiotomy pain.

Analgesic efficacy of piroxicam in the treatment of postoperative pain.

Two randomized, double-blind, single-dose studies were conducted to assess the analgesic efficacy and safety of piroxicam for the treatment of moderate or severe postoperative pain. Study 1 evaluated the analgesic efficacy of piroxicam 20 mg compared with that of codeine sulfate 60 mg and placebo. A final patient population of 149 subjects rated pain intensity and pain relief at one half hour and one hour following treatment and then hourly for six hours, with a global assessment made at the completion of 24 hours. Piroxicam 20 mg was significantly more efficacious than placebo for all analgesic variables, including the sum of the pain intensity differences (SPID), total pain relief (TOTAL), percent SPID, duration of effect, and time to remedication. Codeine 60 mg was significantly superior to placebo for percent SPID and some hourly measures. Piroxicam 20 mg was significantly more effective than codeine 60 mg for percent SPID and a few hourly measures including time to remedication. Study 2 assessed the efficacy of piroxicam 20 mg or 40 mg compared with aspirin 648 mg and placebo. Sixty patients rated their pain intensity and relief hourly for 12 hours and at 24 hours after administration of study medication. Both doses of piroxicam were significantly more effective than placebo from Hours 2 to 12 for pain intensity difference (PID) and relief scores, as well as for SPID and TOTAL. Aspirin was significantly more effective than placebo from Hours 2 to 8 for relief and Hours 2 to 10 for PID as well as SPID and TOTAL. Piroxicam 40 mg was significantly more effective than aspirin 648 mg for SPID, TOTAL, and hourly measures beginning with Hour 6 through Hour 12. Piroxicam 20 mg was significantly better than aspirin for a few hourly measures: Hours 7 to 9 for relief and Hour 7 for PID. In addition, effects of piroxicam 20 mg had a significantly longer duration than aspirin. Similarly, piroxicam 20 mg had a significantly longer time to remedication compared with aspirin and placebo. The results of these studies provide evidence in support of the longer duration of analgesic efficacy of piroxicam compared with codeine or aspirin in patients with postoperative pain.

Analgesic efficacy of ketoprofen in postpartum, general surgery, and chronic cancer pain.

This article summarizes the results of five single-dose clinical studies of three pain models: postpartum, postoperative, and chronic cancer pain. The efficacy of ketoprofen (in varying doses from 25 to 225 mg) was compared with one of the following standards: aspirin (650 mg), codeine (90 mg), acetaminophen (650 mg) plus codeine (60 mg), and parenteral morphine (5 mg and 10 mg). The results indicate that ketoprofen in doses as low as 25 mg has analgesic properties significantly superior to those of placebo. For the treatment of postpartum pain, ketoprofen was significantly more effective than aspirin 650 mg but not significantly different from codeine 90 mg. Ketoprofen doses of 50 mg and 150 mg also provided analgesia superior to that with acetaminophen 650 mg plus codeine 60 mg for the management of moderate to severe postoperative pain. Moreover, oral doses of ketoprofen (75 and 225 mg) provided analgesia similar to that obtained with 5 and 10 mg parenteral doses of morphine. Adverse effects related to ketoprofen were relatively minor and infrequent. Ketoprofen was recently approved for use as an analgesic for treatment of mild to moderate pain in total daily doses up to 300 mg; the recommended initial dose is 25 to 50 mg every 6 to 8 hours as necessary.

Analgesic effect of picenadol, codeine, and placebo in patients with postoperative pain.

A double-blind, parallel study was conducted to evaluate the analgesic effect and safety of a single 25 mg oral dose of picenadol, a centrally acting analgesic, and to compare it with a 60 mg dose of codeine and a placebo in patients with postoperative pain. Two sites using similar protocols enrolled a total of 178 inpatients with postoperative pain. Pain intensity, relief, and adverse experiences were then measured for up to 6 hours after administration of the test medications. Both picenadol and codeine were significantly more effective than placebo in reducing pain intensity (mean sum of pain intensity difference scores: picenadol 5.21, codeine 5.19, and placebo 2.82) and increasing total relief (mean total pain relief: picenadol 10.21, codeine 11.07, and placebo 6.96). Adverse experience profiles were similar among the three treatment groups.

Analgesic efficacy of two ibuprofen-codeine combinations for the treatment of postepisiotomy and postoperative pain.

Our purpose was to compare the analgesic efficacy and safety of single oral doses of the combination of ibuprofen 400 mg plus codeine 60 mg and the combination of ibuprofen 200 mg plus codeine 30 mg with ibuprofen 400 mg alone, codeine sulfate 60 mg alone, and placebo. One hundred ninety-five patients with severe pain resulting from episiotomy, cesarean section, or gynecologic surgery completed a randomized, double-blind, stratified, parallel-group study. Patients were observed during a 4-hour period after medication. Based on the sum of the pain intensity differences (SPID), total pain relief (TOTPAR), and most of the hourly direct measures of pain and relief, both doses of the combination and ibuprofen 400 mg alone were statistically superior to placebo. Codeine 60 mg was statistically superior to placebo based on TOTPAR, the global ratings, and a few hourly measures. The mean effect of the combination of ibuprofen 400 mg plus codeine 60 mg was significantly superior to the mean effect of ibuprofen 400 mg alone 1/2, 1, and 2 hours after medication and to the mean effect of ibuprofen 400 mg alone and codeine 60 mg alone for SPID, TOTPAR, and other measures as well. The low-dose combination was significantly more effective than codeine 60 mg for a few hourly measures but was not significantly superior to ibuprofen 400 mg. Based on these findings it appears that the combination of ibuprofen 400 mg plus codeine 60 mg, particularly in the first few hours after medication, is more efficacious than its constituents.
