BACKGROUND/AIMS: Little is known about the clinical efficacy of co-therapy of enprostil, a prostaglandin E2 analogue, with a histamine H2-receptor antagonist. We aimed to assess the additive benefit of enprostil in combination with cimetidine for treating gastric ulcer in a prospective multicenter randomized controlled trial.
METHODOLOGY: In 43 hospitals 171 intention-to-treat (ITT) patients, diagnosed as having gastric ulcer by endoscopy, were randomly allocated to receive either enprostil 25microg b.i.d. and cimetidine 400mg b.i.d. (Group E=85), or cimetidine 400mg b.i.d. alone (Group C=86) for 8 weeks. Healing was examined by endoscopy at 4 and 8 weeks.
RESULTS: Per protocol (PP) analysis comprised 166 patients (E=82, C=84). Despite no significant advantage at 4 weeks (E=55.3%, C=42.2%), the combination yielded higher healing rates at 8 weeks by ITT (E=89.4%, C=68.6%; p<0.001) and PP analysis (E=92.7%, C=70.2%; p<0.001). Symptom relief rates [E, C] at 2, 4, and 8 weeks were [80.2%, 68.3%] (not significant), [97.4%, 88.3%] (p<0.05), and [95.6%, 87.0%] (p<0.05), respectively. Significant advantage was observed in the patients aged 40 or older, with solitary ulcer (>5mm in diameter), and without smoking or drinking habits. No adverse effects were critical.
CONCLUSIONS: Enprostil safely and significantly augmented gastric ulcer healing and symptom relief by cimetidine.
