We recently demonstrated that 25 mg of bromfenac, a new nonsteroidal anti-inflammatory analgesic, is at least as effective as 400 mg of ibuprofen in relieving postoperative oral surgery pain. Our objective in this study was to determine whether higher doses were significantly more effective. Two hundred eighty (280) outpatients with postoperative pain after the surgical removal of impacted third molars were randomly assigned, on a double-blind basis, a single oral dose of 10, 25, 50, or 100 mg bromfenac; 650 mg aspirin; 400 mg ibuprofen; or placebo. Subjects rated their pain and its relief for 8 hours. All active treatments were significantly superior to placebo, and bromfenac and ibuprofen were significantly superior to aspirin. The slope of the dose-response curve of bromfenac was significant. The 100 mg bromfenac dose was significantly more effective than the 400 mg ibuprofen dose and had a significantly longer duration of analgesic action. The object of the study was to assess the comparative efficacy of three single doses (200, 400, 600 mg) of soluble ibuprofen and ibuprofen tablets after third molar surgery in 148 patients and aged 18-40 years. Outcome was measured by overall assessment of pain (AUC360) assessed from serial visual analogue scales, the number of patients taking additional analgesic and by overall assessment of medication evaluated on a five-point categorical scale. Over the 6-hour investigation period all the ibuprofen treatments with the exception of ibuprofen tablets 200 mg resulted in significantly less pain (p < 0.05) than placebo treatment. A large number of patients required additional analgesia during the investigation period, but the time to taking it was significantly earlier in the placebo group. No significant dose response (p > 0.05) was observed for either ibuprofen preparations assessed by the outcome variable of overall pain experience (AUC360) or time to additional analgesia. There was no significant difference in pain scores or time to taking additional analgesics between the respective doses of soluble and tablet formulations of ibuprofen. Both soluble and tablet formulations of ibuprofen provide effective pain control in the early postoperative period after removal of impacted third molars. There is little analgesic advantage in increasing the dose to 600 mg and only minimal benefit from using a soluble formulation of the drug. 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. In a double-blind, parallel, placebo-controlled study, 203 patients with post-operative dental pain following the extraction of one or two bony impacted third molars were randomized to receive a single dose of naproxen sodium 220 mg, ibuprofen 200 mg or placebo. Pain intensity and pain relief were assessed at intervals for 12 hours postdose. Both active drugs demonstrated superior analgesic efficacy over placebo. Naproxen sodium and ibuprofen were comparable both in onset of analgesic action and in pain relief. From 1 to 12 hours postdose, naproxen sodium showed a trend for superior analgesic efficacy compared with ibuprofen; this trend reached statistical significance at the 12-hour time point. Both drugs were well-tolerated and effective analgesics for postoperative dental pain. This single-dose, double-blind, parallel-group, single-site study compared ibuprofen lysine 400 mg with acetaminophen 1000 mg and placebo in 240 patients with moderate-to-severe postoperative dental pain. The relative onset of analgesic response, overall analgesic efficacy, duration of effect, and safety were assessed over a 6-hour postdose period. Analgesic efficacy was assessed by patient self-rating of pain intensity, pain relief, time to meaningful pain relief, need for additional analgesic medication, and patient global evaluation. Both ibuprofen lysine 400 mg and acetaminophen 1000 mg were significantly (P < or = 0.05) more effective than placebo. Ibuprofen lysine had a significantly (P < or = 0.05) faster onset of action with greater peak and overall analgesic effect than did effect than did acetaminophen. All treatments were generally well tolerated. Multimodal pain management has been suggested to improve postoperative analgesia. In this study, we evaluated the quality of analgesia in women undergoing day-case gynaecological laparoscopic surgery, after premedication with pregabalin 75 mg (P75) or 150 mg (P150), compared with diazepam 5 mg (D5). All patients were given ibuprofen 800 mg orally.
                Altogether 90 consenting women were anaesthetized in a standardized fashion. Postoperative analgesia was provided by ibuprofen 800 mg twice a day with fentanyl i.v. on request in the recovery room (RR), and combination tablets with acetaminophen and codeine after the RR. The visual analogue scale (VAS) scores for pain and side-effects and the amounts of postoperative analgesics were recorded for 24 h after surgery. The areas under the curves (AUC) were calculated for the VAS scores for pain at rest, pain in motion, and pain at cough 1-8 and 1-24 h after surgery.
                The median AUC values for VAS scores for pain at rest (P=0.048) and in motion (P=0.046) 1-8 h after surgery were lower in the P150 group than that in the D5 group. The amounts of rescue analgesics or the degree of drowsiness did not differ in the three study groups.
                Analgesia was better after premedication with pregabalin 150 mg than after diazepam 5 mg, both with ibuprofen 800 mg, during the early recovery after day-case gynaecological laparoscopic surgery. Pregabalin 150 mg did not reduce the amount of postoperative analgesics required. The aim of the present placebo-controlled, double-blind study was to evaluate the comparative efficacy of single doses of aceclofenac 150 mg and ibuprofen 400 mg in 217 patients with postoperative pain after third molar surgery. Outcome of primary efficacy was judged by overall assessment of the area under the curve (AUC) of graphs for pain intensity (AUC pain) pain relief (AUC relief), both measured from serial visual analogue scales over a 6 h investigation period. Other measures of efficacy included the rate of pain reduction in the first hour, the number of patients who took 'escape' analgesics and the time before they did, and an overall assessment of pain relief score on a five-point categorical scale. Ibuprofen 400 mg was significantly superior to placebo for pain relief (P < 0.01), degree of pain reduction in the first hour (P = 0.005), and the number of patients who required escape analgesia (P < 0.001), and the time before they did (P < 0.001). The outcome for patients treated with aceclofenac 150 mg was not significantly different from that of patients treated with placebo (P > 0.05). A single dose of ibuprofen 400 mg provided significant pain relief in the early postoperative period after third molar surgery, whereas a single dose of aceclofenac 150 mg was not effective in the management of postoperative pain after this operation. The purpose of this study was to compare the analgesic efficacy and safety of meclofenamate sodium with ibuprofen after dental impaction surgery. This study was double-blind and used a unique methodology. Patients (N = 254) were first randomized into the single dose phase of the study that included placebo, meclofenamate 50 mg, meclofenamate 100 mg, ibuprofen 200 mg, and ibuprofen 400 mg, followed by a 7-day multidose phase in which patients in the placebo group were rerandomized into one of the active treatment cells. In the single dose phase, all active treatments were significantly more efficacious than placebo for every summary analgesic measure. A positive dose-response was seen for both active drugs with meclofenamate 100 mg and ibuprofen 400 mg exhibiting the greatest efficacy for pain relief, pain reduction, time to remedication, and overall evaluation. Side effects were reported by 26 patients. They were evenly distributed among treatment groups with headache and drowsiness being the most common. During the multidose phase, there were only small differences in efficacy measures among active treatment groups. However, meclofenamate produced a higher incidence of stomach cramps and diarrhea than did ibuprofen (8.8% and 7.2% versus 0.8% and 0.8%). This study indicates that higher doses of nonsteroidal anti-inflammatory drugs are most effective immediately after surgery and that lower doses of these drugs can be used after the first postoperative day. The side effect profile of nonsteroidal anti-inflammatory analgesics is best observed with the use of a multidose study design. Celecoxib 200 mg has been reported to reduce pain following dental extraction but to offer poorer pain relief than active comparators.
                The aim of this study was to compare the efficacy and tolerability of celecoxib 400 mg, the recommended loading dose for treatment of acute pain, with that of ibuprofen 400 mg and placebo following oral surgery.
                This was a single-dose, 2-center, randomized, double-blind, active- and placebo-controlled study in which patients with moderate to severe pain following third molar extraction were randomized to receive a single dose of celecoxib 400 mg, ibuprofen 400 mg, or placebo. Pain assessments were completed using a 4-point pain intensity scale where 0=no pain and 3=severe pain and a 5-point pain relief scale where 0=no pain relief and 4= complete pain relief at baseline and 18 time points over 24 hours. Primary efficacy outcome measures were time to onset of analgesia (the median time to perceptible pain relief in those patients who achieved meaningful pain relief), time-specific pain intensity difference (PID), time-specific pain relief (PR), time-specific sum of PID and PR, and time to use of rescue medication. Times to perceptible and meaningful pain relief (secondary efficacy outcome measures) were recorded using 2 stopwatches. Tolerability was assessed through recording of adverse events, clinical laboratory tests, and physical examinations (including collection of vital signs).
                One hundred seventy-one patients were randomized to celecoxib 400 mg (30 women and 27 men; mean [SD] age, 21.4 [4.2] years); ibuprofen 400 mg (30 women and 27 men; mean [SD] age, 22.0 [4.7] years); or placebo (34 women and 23 men; mean [SD] age, 21.6 [5.0] years). Mean times to onset of analgesia with celecoxib 400 mg and ibuprofen 400 mg were rapid and comparable (median 28 minutes and 26 minutes, respectively) and were significantly shorter than with placebo (>24 hours) (both, P<0.05 vs placebo). Compared with placebo, mean time-specific PID scores were significantly greater with celecoxib from 0.5 to 24 hours and with ibuprofen from 0.5 to 16 hours (all, P<0.05 vs placebo). Time-specific PR scores with celecoxib and ibuprofen were significantly greater from 0.75 and 0.5 hour, respectively, compared with placebo (all, P<0.05 vs placebo). PID was significantly greater with celecoxib compared with ibuprofen beginning at 11 hours (all, P<0.05). PR scores were significantly higher with celecoxib versus ibuprofen beginning at 9 hours (all, P<0.05). Median (95% CI) time to use of rescue medication with celecoxib (>24 hours) was significantly longer than with ibuprofen (10 hours, 58 minutes [8 hours, 30 minutes- 14 hours, 34 minutes]) or placebo (1 hour, 51 minutes [1 hour, 40 minutes-2 hours, 22 minutes]) (both, P<0.05). The 3 most common adverse events experienced in the celecoxib group were headache (9 [15.8%] patients), nausea (9 [15.8%] patients), and dizziness (6 [10.5%] patients).
                In this postsurgical dental pain study, the onset and magnitude of pain relief with celecoxib 400 mg and ibuprofen 400 mg were found to be comparable. In addition, patients who received celecoxib 400 mg as a single dose had a significantly longer time to use of rescue medication and had higher pain relief scores later in the study than those who received ibuprofen 400 mg. Celecoxib was well tolerated compared with placebo.
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.
