Abstract

Three pharmacological agents in use as "potassium-sparing" drugs have been tested by serial measurements of total exchangeable potassium (K(E)) during 4 to 12 weeks of oral diuretic therapy in hypertensive subjects. Triamterene seemed ineffective in the dosage used (50 mg twice daily). Spironolactone (25 mg twice daily) reduced K loss to a considerable extent, while Slow-K (32 mEq daily) completely reversed previous K(E) deficits. Plasma K levels were a poor indication of degree of K(E) restoration.

摘要

在高血压患者口服利尿剂治疗4至12周期间,通过连续测量总可交换钾(K(E)),对三种用作“保钾”药物的药理剂进行了测试。氨苯蝶啶在所使用的剂量(每日两次,每次50毫克)下似乎无效。螺内酯(每日两次,每次25毫克)在很大程度上减少了钾的流失,而缓释钾(每日32毫当量)则完全逆转了先前的K(E)缺乏。血浆钾水平并不能很好地指示K(E)恢复的程度。
