The ocular effects of the alpha-adrenoceptor blocking drug bunazosin, administered as eyedrops, have been measured in a placebo-controlled double-blind single-dose study in 15 healthy volunteers. The drug significantly reduced intraocular pressure over 10 hours, and there was no associated change in pulsatile ocular blood flow. Characteristic effects of alpha-adrenoceptor blockade were observed--miosis, ptosis, and conjunctival hyperaemia. The miosis alone persisted for more than 24 hours in nine out of 15 subjects.
在一项针对15名健康志愿者的安慰剂对照双盲单剂量研究中,对以眼药水形式给药的α-肾上腺素受体阻断药物布那唑嗪的眼部效应进行了测量。该药物在10小时内显著降低了眼压,且搏动性眼血流量没有相关变化。观察到了α-肾上腺素受体阻断的典型效应——瞳孔缩小、上睑下垂和结膜充血。仅瞳孔缩小在15名受试者中有9名持续超过24小时。
