强心甙是用于改善心功能不全的一种重要药物。近年来,为了弥补天然强心甙的不足,一类新的半合成强心甙得到迅速发展,其特点为剂量较小、安全性较高、口服吸收好、生效迅速。其中以β-甲基狄戈辛有较多优点。目前这类药物尚处于研究阶段。为了发展我国的半合成强心甙,杭州第一制药厂用本厂产品狄戈辛合成了β-甲基狄戈辛。 Cardiac glycosides are an important drug used to improve cardiac insufficiency. In recent years, to make up for the lack of natural cardiac glycosides, a new class of semi-synthetic cardiac glycosides have been rapidly developed, characterized by a smaller dose, higher safety, good oral absorption, rapid effect. Among them, β-methyl digoxin has more advantages. Currently such drugs are still in the research stage. In order to develop semi-synthetic cardiac glycosides in China, Hangzhou No. 1 Pharmaceutical Factory synthesized β-Methyl Digoxin with Dioxin.
