The activity of clarithromycin-14-hydroxyclarithromycin (2:1 ratio) and bismuth subsalicylate or amoxicillin against Helicobacter pylori was determined by the checkerboard technique in vitro. Clarithromycin-14-hydroxyclarithromycin and amoxicillin resulted in additive effects in 7 of 22 isolates, compared to 14 of 22 isolates when bismuth subsalicylate was substituted for amoxicillin. Synergy was not demonstrated and is probably not responsible for the clinical success of treatment combinations containing clarithromycin.
采用棋盘稀释法在体外测定了克拉霉素-14-羟基克拉霉素(2:1比例)与次水杨酸铋或阿莫西林对幽门螺杆菌的活性。克拉霉素-14-羟基克拉霉素与阿莫西林联合使用时,22株分离株中有7株呈现相加作用;而用次水杨酸铋替代阿莫西林时,22株分离株中有14株呈现相加作用。未显示出协同作用,含克拉霉素的治疗组合临床疗效可能并非归因于协同作用。
