Enprostil, a prostaglandin E2 analogue, in the treatment of gastric ulcer--a multicentre comparison with pirenzepine.
In a double-blind, multicentre study 77 patients with benign gastric ulcer were randomly allocated to treatment with either enprostil 35 micrograms bd or pirenzepine 50 mg bd. After four weeks of treatment 13/26 (50 per cent) of evaluable enprostil-treated patients and 9/30 (30 per cent) of evaluable pirenzepine-treated patients were healed. Corresponding healing figures after eight weeks were 20/25 (80 per cent) and 25/31 (81 per cent). Both drugs rapidly reduced the severity of ulcer pain and the need for antacid use. No statistically significant differences were detected between the treatments with respect to healing rate or symptom control. Adverse events were reported by eight patients taking enprostil and by 17 patients taking pirenzepine. Two patients withdrew from each treatment group because of adverse events. None of these was serious. In conclusion, enprostil and pirenzepine were equally effective in healing gastric ulcers and no statistically significant differences in safety and efficacy were detected. There was a tendency for earlier healing and fewer side effects in the enprostil-treated patients.
