Misoprostol and dalargin for the inpatient treatment of duodenal ulcer in the USSR.

In the USSR, uncomplicated duodenal ulcer is usually managed in an inpatient setting. A double-blind, randomized, double-dummy, multiclinic, comparative trial examined the safety and efficacy of oral misoprostol (200 micrograms qid) and intramuscular dalargin (1 mg bid) in duodenal ulcer healing. Dalargin, an enkephalin peptide with gastric antisecretory and cytoprotective properties, is commonly used in the USSR for treating peptic ulcer.
