Objective To compare the efficacy of Dailixin plus omeprazole with that of omeprazole in the treatment of functional dyspepsia(FD),and three-month relapse of them.Methods 110 patients with FD were divided into observing group(n=60) and control group(n=50) randomly.The former group was administered with Dailixin and omeprazole,and the latter one with omeprazole.Their clinical symptoms were compared.Results The effective rate and three-month relapse rate were respectively 95.0% and 13.3% in the observing group,while the counterparts of the control group were 88.0% and 24.0%.There were significant differences in the parameters between the two groups(P0.05).Conclusion Dailixin plus omeprazole is safe and effective in the treatment of FD.Maintaining treament is required in many patients.
