Metformin 的正确用法是:
吃饭时吃(take with meal),一日二次!
而你晚饭后吃二片(500 mg/片),显然没有遵医嘱或者医生水平太差,没有告诉你正确的服用方法(if has side effect, take in the evening jsut after dinner)!
不同的药物作用方式不同,因此服用时间有别。
Its pharmacologic mechanisms of action are different from other classes of oral antihyperglycemic agents. Metformin decreases hepatic glucose production, decreases intestinal absorption of glucose, and improves insulin sensitivity by increasing peripheral glucose uptake and utilization.
