匹伐他汀背景及作用機理：
冠心病是威脅人類健康和生命的常見病和多發(fā)病，以低密度脂蛋白(LDL)升高為特征的高膽固醇血癥則是誘發(fā)冠心病的主要危險因子之一。常用的降血脂藥如煙酸類、樹脂類或貝特類等療效都難盡人意，降脂作用的是被稱為他汀類(statins)的藥物。他汀類藥物共同的作用機制是都屬于3—羥—3—甲基—戊二酰輔酶A(HMG—CoA)還原酶抑制劑，目前在世界廣泛應用的主要有6種：洛伐他汀(lovastatin)，普伐他汀(pravastatin)，辛伐他汀(simvastatin)，西立伐他汀(cerivastatin)，氟伐他汀(fluvastatin)和阿托伐他汀(atorvastatin)。而近期由Kowa公司開發(fā)的新型他汀類藥物匹他伐他汀鈣，因其良好的降膽固醇作用而被稱為“超級他汀類藥物”(Superstatin)。
