Dysmenorrhea: treatment with an antiprostaglandin.
Painful menses, one of the most frequent gynecologic complaints, is incapacitating for many women. It has recently been proposed that increased endometrial prostaglandin production and prostaglandin-induced myometrial contractility may be responsible for dysmenorrhea. In this prospective, double-blind, 3-way, crossover study, relief of pain by an antiprostaglanding drug, ibuprofen (400 mg), was compared with propoxyphene (64 mg) and placebo in 22 women with severe primary dysmenorrhea. Ibuprofen was significantly more effective in 18 patients when compared to the other 2 treatment regimens (P less than 0.001), while propoxyphene was superior to placebo in 13 patients (P less than 0.05). Prostaglandin E and F synthesis rates in endometrial biopsy specimens taken on the second day of treatment in 2 patients during each treatment cycle were lowest during ibuprofen in one case but showed no definite pattern in the second.
