A comparative study on the analgesic effects of indomethacin and hydromorphinechloride-atropine in acute, ureteral-stone pain.

In a prospective study, including fifty consecutive patients with acute ureteral-stone pain, the patients were randomly distributed into two groups for treatment. There were given either an intravenous injection of indomethacin (Confortid) 50 mg, or a subcutaneous injection of 2 mg hydromorphine chloride-atropine (Dilaudid-atropin 1 ml). Patients in the latter group also received a suppository of prochlorperazine (Stemetil) 25 mg. The analgesic effect of the two drugs did not differ significantly. Indomethacin was quicker acting, probably due to the intravenous route of administration. The side effects were alike but those caused by indomethacin had a tendency to be milder and of shorter duration.
