不同时间服用比索洛尔治疗非杓型原发性高血压的疗效评价

目的:观察不同给药时间分别给予比索洛尔对非杓型原发性高血压患者的降压疗效和血压节律恢复的影响。方法:选取60例非杓型高血压患者,采取随机平行对照试验,观察比索洛尔(n=30)每日早晨(8∶00)给药2.5~10 mg、比索洛尔(n=30)每日夜间(20∶00)给药2.5~10 mg治疗8周后的降压疗效。结果:两种给药方法均能降低非杓型高血压患者的全天血压(P<0.05)。两种给药方法在白天的血压控制上无统计学差异(P>0.05),但在夜间血压的控制上夜间服药降压效果具有统计学差异(P<0.05)。夜间服药在血压节律恢复方面优于早晨服药(P<0.05),早晨服药组有10例恢复杓型,夜间服药组有19例恢复杓型。结论:比索洛尔的两种给药方式均能安全有效地降压,但对于非杓型高血压患者夜间服药优于早晨服药,更有利于血压节律的恢复。
