The effects of single doses of clonidine hydrochloride (200 micrograms), yohimbine hydrochloride (22 mg), a combination of the two treatments, and placebo, on some autonomic functions were studied in healthy volunteers using a double-blind crossover design. Clonidine prolonged the recovery time of the light reflex, lowered systolic blood pressure and reduced subjectively rated alertness; these effects were reversed by yohimbine. Responsiveness of sweat glands to carbachol was not affected by the treatments.
采用双盲交叉设计,在健康志愿者中研究了单次剂量的盐酸可乐定(200微克)、盐酸育亨宾(22毫克)、两种治疗方法联合使用以及安慰剂对某些自主神经功能的影响。可乐定延长了光反射的恢复时间,降低了收缩压,并降低了主观评定的警觉性;这些作用被育亨宾逆转。汗腺对卡巴胆碱的反应性不受这些治疗的影响。
