UpToDate:

藥理作用 :
Dopamine可加強心肌收縮力,因而增加心輸出量。本品較之Isoproterenol不會增加心肌耗氧量且不併發心跳加快。臨床研究顯示本品可增加心縮壓及脈搏壓,而不影響心輸壓或僅稍微增加。在低劑量及中劑量時,全部周邊血管阻力不變。本品可活化腎血管之dopaminergic接收器,因而擴張腎血管,致使腎血流腎小球濾過率、鈉排出量及尿量等均增加。

適應症:
休克症候群及心臟衰竭。

用法用量:
本品不得直接皮下,肌肉或直接靜脈注射。需以5%葡萄糖液或生理食鹽水稀釋後靜脈點滴靜注。初劑量速率為每分鐘2~5μg/kg,而後視病人之血壓,心輸出量,尿量而漸增速率每分鐘1~10μg/kg遇嚴重之病情,若需要時可增至每分鐘速率20~50μg/kg(最多為50μg)。

副作用:
噁心、嘔吐、心悸、心跳過速、稍低血壓、中等程度的呼吸困難。
