Comparative StudyA double-blind comparison of a propionic acid derivative (ibuprofen) and a fenamate (mefenamic acid) in the treatment of dysmenorrhea.
A double-blind three-way crossover design in the treatment of dysmenorrhea comparing a propionic acid derivative (ibuprofen) and a fenamate (mefenamic acid) with a placebo showed that both ibuprofen and mefenamic acid are generally superior to placebo. Statistically significant results were obtained in favor of the study drugs over placebo for the pain relief afforded by the treatments (as graded by patients) and the visual analog pain relief score, which not only ranks but also indicates the degree of pain relief as a percentage of total relief (100%). Pairwise comparisons for the ranks found mefenamic acid significantly superior to placebo (P less than .001) and ibuprofen marginally superior to placebo (P less than .06), while the visual analog pain relief scale demonstrated mefenamic acid and ibuprofen superior to placebo (P less than .001 and P less than .01, respectively). ⋯ These were generally of minor severity or importance and were not statistically different. The need for additional analgesics and the ability to pursue normal daily activity were not different for any treatment group. The findings of this study indicate no clinical difference between a propionic acid derivative such as ibuprofen and a fenamate such as mefenamic acid in the treatment of dysmenorrhea.

Comparative Study Clinical Trial
Suppression of postoperative pain by preoperative administration of ibuprofen in comparison to placebo, acetaminophen, and acetaminophen plus codeine.
The analgesic effect of preoperatively administered ibuprofen was evaluated in 107 dental outpatients undergoing the removal of impacted third molars. Subjects were given 800 mg ibuprofen prior to the procedure and 400 mg ibuprofen 4 and 8 hours later. Comparison was made to groups receiving either placebo at all three doses, 600 mg acetaminophen administered on the same schedule, or preoperatively administered placebo followed by two doses of postoperatively administered 600 mg acetaminophen plus 60 mg codeine. ⋯ Ibuprofen also resulted in less postoperative pain than acetaminophen plus codeine following the second dose. Side effects were similar across drug treatments and placebo with the exception of greater reports of drowsiness following the opiate-analgesic combination. These findings indicate that pretreatment with a nonsteroidal antiinflammatory drug, such as ibuprofen, results in a suppression of postoperative pain when compared to standard therapy without an increase in side effects.

Randomized Controlled Trial Clinical Trial
Analgesic efficacy of an ibuprofen-codeine combination.
Subjects who had undergone dental impaction surgery and who had moderate to severe postoperative pain were given, under double-blind, randomized conditions, a single dose of either codeine 60 mg, aspirin 650 mg, ibuprofen 400 mg, aspirin 650 mg + codeine 60 mg, ibuprofen 400 mg + codeine 60 mg, or placebo. A total of 249 subjects were included in the statistical analysis. On a report form, subjects recorded pain intensity, pain relief, and side effects hourly for four hours. ⋯ There was no notable difference in the frequency or intensity of side effects among the treatment groups, and no subject had to withdraw due to an adverse effect. This study again confirms the superiority of ibuprofen to aspirin and suggests that ibuprofen is at least as effective as an aspirin-codeine combination. Codeine added a small amount of additional analgesia when used in combination with ibuprofen.

Randomized Controlled Trial Clinical TrialAnalgesic efficacy of ibuprofen for treatment of primary dysmenorrhea.
Fifty-five women with primary dysmenorrhea were enrolled in a study which each took ibuprofen (400 mg), propoxyphene hydrochloride (64 mg), or a placebo alternately in consecutive menstrual cycles for relief of pain. Fifty-one completed the study during three successive cycles in this triple-blind, crossover, randomized investigation. Ibuprofen was clearly superior to propoxyphene and the placebo in patient preference, degree of relief, and need for supplementary analgesics. ⋯ Propoxyphene was superior to the placebo but not to the same extent as ibuprofen. Only three side effects were reported during the study, two relative to propoxyphene and one recorded during a placebo cycle. These data show that ibuprofen is an effective agent when used for treatment of dysmenorrhea without organic etiology.
