[ Triple therapy regimens involving H2 blockaders for therapy of Helicobacter pylori infections ] . Comparison of ranitidine and lansoprazole in short-term low-dose triple therapy for Helicobacter pylori infection . To evaluate the efficacy and safety of two 1-week low-dose triple-therapy drug regimens involving antisecretory drugs for Helicobacter pylori infection , 99 patients with H. pylori infection were treated with either lansoprazole ( LPZ ) or ranitidine ( RNT ) used together with clarithromycin ( CAM ) and metrinidazole ( MTZ ) . The drug combination and administration periods in the PPI group were LPZ 30 mg , CAM 400 mg , MTZ 500 mg ( LCM group ) . The ranitidine group received RNT 300 mg , CAM 400 mg , MTZ 500 mg ( RCM group ) . The cure rate of H. pylori infection was 88 % in the LCM group ; 95 % CI 79-97 and 92 % in the RCM group ; 95 % CI 84-99 .
