AIM: To evaluate the efficacy of weishusan on functional dyspepsia and to investigate the potential effect of eradication of H. pylori on gastritis and symptomatology of H. pylori -positive dyspepsia.METHODS: Total 87 patients with functional dyspepsia were randomized to receive weishusan (3. 0 tid, n = 56) or mosapride (5 mg tid, n = 31) for 4 weeks. The symptom score and severity of gastritis were assessed by clinical practitioners and endoscopy separately. Serum motilin (Mot), gastrin (Gas) and H. pylori were detected.RESULTS: Symptom improvement was significant in weishusan group and mosapride group (85.7 % vs 80.6 %, NS). The motilin level was significantly higher after treatment in both groups (457 ± 119 ng· L-1 vs 410 ± 106 ng· L-1, P 0. 01). The total effective rate of gastritis improvement in weishusan group (57.7 %) was significantly higher than that in mosapride group (20.7 %, P 0.01). Regarding H. pylori status, eradication of H. pylori was achieved in 41.9 % (18/ 31) in weishusan group and no one in mosapride group (0/14,0%, P0.01). No differences in the symptom score improvement were observed between patients with eradication, persistent infection and without infection. The gastritis improvement in patients with eradication (83. 8 %) was significantly higher than those without infection (47.2 %, P 0. 05), and those persistent infection (14.8 %, P0.01). The gastrin level in H. pylori positive patients was significantly higher than that in H. pylori negative patients (47 ± 17 ng· L-1 vs 36 ± 13 ng· L-1 P 0.05). After eradication the gastrin level decreased but no significant differences were observed (P 0.05).CONCLUSION :Weishusan is a good prokinetic drug and has effect on functional dyspepsia. It also has effects on protection of gastric mucosa and on eradication of H. pylori, which seems not to contribute to the timely symptom improvement of dyspepsia.
