Treatment of ureteral and biliary pain with an injectable salt of indomethacin.

A study was carried out to investigate the analgesic effect of an injectable salt of indomethacin - methylglucamine indomethacinate - in patients with acute ureteral and biliary pain. Out of 106 consecutive patients treated by the intramuscular (average dose 72.6 mg) or intravenous (average dose 36.1 mg) route, 76 (71.6%) had complete relief of pain and 4 were remarkably improved. In 68.8% of the cases, complete relief was reached within 1 hour from the start of treatment. No important side-effects were observed. Headache, nausea and drowsiness were reported in a few cases.
