Abstract

In vitro incubation of human erythrocytes and platelets with the 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor pravastatin in the concentration range 1 nM to 10 microM did not affect the activity of the Na(+)-K(+)-pump, Na(+)-K(+)-cotransport or Na(+)-Li(+)-countertransport, or the ground membrane leak for Na+ and K+. The data indicate that pravastatin has no direct effect on transmembrane cationic transport systems in red blood cells or platelets.

摘要

在1纳摩尔至10微摩尔浓度范围内,用3-羟基-3-甲基戊二酰辅酶A还原酶抑制剂普伐他汀对人红细胞和血小板进行体外孵育,并未影响钠钾泵、钠钾协同转运或钠锂逆向转运的活性,也未影响钠和钾的基底膜渗漏。数据表明,普伐他汀对红细胞或血小板中的跨膜阳离子转运系统没有直接影响。
