The possible role of prostaglandins (PGs) in the biochemistry of endometriosis prompted this placebo-controlled double-blind trial evaluating the effect of PG-inhibitors on symptoms of endometriosis (especially pelvic pain). The 4 drugs used were: 1) placebo, 2) acetylsalicylic acid (ASA), 3) indomethacin, and 4) tolfenamic acid. Each drug was administered orally from Day 20 of the menstrual cycle until end of menstruation for 2 consecutive cycles. During menstruation, tolfenamic acid (P.01) and ASA (P.05) lowered the endometriosis score from the pretreatment level. Tolfenamic acid was more effective than placebo (P.05), whereas ASA and indomethacin did not differ from placebo. Each treatment, including placebo, lowered the endometriosis score (P.05) during the menstrual period, but none of the PG inhibitors was more effective than placebo (P.05). According to patient's subjective judgements, tolfenamic acid alleviated symptoms more effectively than other drugs tested. Pain symptoms occurred less often during tolfenamic acid and ASA than during placebo or indomethacin (P.05). Gastrointestinal side effects were more common with indomethacin and ASA (P.05). Indomethacin treatment raised the incidence of psychic complaints over those with ASA or placebo (P.05). Side effects were fairly evenly distributed among the therapies.
