Abstract:
Objective To evaluate the efficacy and safety of ilaprazole sodium for injection in the treatment of peptic ulcer bleeding.Methods It was designed as a multi-center,stratified randomized,double-blind,positive drug parallel controlled and non-inferiority study.From October 2014 to April 2015,at 40 hospitals,patients with peptic ulcer hemorrhage confirmed by gastroendoscopy were enrolled and divided into the ilaprazde sodium group (10 mg ilaprazole sodium for injection every 24 h,the first dose doubled) and the positive control group (40 mg of omeprazole sodium for injection every 12 h).The course of both treatment was 72 h.The hemostasis rate of overall group at 72 h,the clinical rebleeding rate at four to seven days,the blood transfusion rate,the incidence of switching to other treatments and the incidence of adverse reactions were compared between the two groups.A chi-square test or Fisher's exact probability method were performed for statistical analysis.Results A total of 533 patients with peptic ulcer bleeding were enrolled,355 patients in the ilaprazole sodium group and 178 patients in the positive control group.The hemostasis rates of ilaprazole sodium group and positive control group at 72 h were 97.69 ％ (339/347) and 97.14 ％ (170/175),respectively,and the difference was not statistically significant (P＞0.05).There were no rebleeding patients in both groups at four to seven days.The blood transfusion rates of ilaprazole sodium group and positive control group were 5.07 ％ (18/355) and 3.37 ％ (6/178).The incidence of switching to other treatments was 0.56％ (2/355) and 0.56％ (1/178),respectively,and the differences were not statistically significant (both P＞ 0.05).The incidence of adverse reactions in the ilaprazole sodium group was 3.94％ (14/355),which was lower than that of positive control group (8.43％,15/178).And the difference was statistically significant (Fisher's exact probability method,P=0.042).Conclusions The efficacy of ilaprazole sodium for injection in the treatment of peptic ulcer bleeding is similar to that of omeprazole sodium for injection.Moreover,the smaller the dose,the lower the frequency of administration and the better the safety.
