PG - 667-73 AB - OBJECTIVE: Assessment of efficacy and safety of meloxicam 7.5 mg and 15 mg once a day (o.a.d.) compared with mefenamic acid 500 mg three times a day (t.i.d.), over a treatment period of 3-5 days, during three menstrual cycles, for primary dysmenorrhea. STUDY DESIGN: Multicenter, multinational, double-blind, double-dummy, three parallel groups, randomized trial, phase IIb, 337 patients. Treatment group comparisons of continuous variables were carried out using the Kruskal-Wallis test and Wilcoxon signed rank tests. Efficacy was analyzed using Fisher and chi(2)-tests. RESULTS: Meloxicam 7.5 mg and 15 mg showed a similar profile in pain reduction and dysmenorrhea symptoms when compared with mefenamic acid. Thirty-five subjects presented with gastrointestinal (GI) adverse events (AEs). Two-thirds of those 35 subjects were in the mefenamic acid group. There were no differences between the safety profiles of the two meloxicam dosages. Laboratory abnormalities did not differ in incidence among the treatment groups. CONCLUSION: Both of the daily doses of meloxicam tested were comparable to 500 mg mefenamic acid t.i.d. in relieving dysmenorrhea symptoms, and meloxicam seems to have a better gastrointestinal tolerability profile.
