Oral timolol, a beta-adrenergic receptor blocker, was given in 5 different doses from 5 mg to 30 mg a day to 12 healthy volunteers in a double-blind cross-over trial. Adrenaline was instilled into one eye in each subject. Recording of intraocular pressure during the trial suggested the presence of a dose-response relationship between the dose of timolol and the decrease of intraocular pressure. An analysis of the interaction of timolol and adrenaline showed that the adrenaline effect diminished linearly with increasing timolol dose, which finally made the combination less effective than timolol alone.
在一项双盲交叉试验中,给12名健康志愿者口服不同剂量(5毫克至30毫克/天)的β-肾上腺素能受体阻滞剂噻吗洛尔。给每个受试者的一只眼睛滴入肾上腺素。试验期间对眼压的记录表明,噻吗洛尔剂量与眼压降低之间存在剂量反应关系。噻吗洛尔与肾上腺素相互作用的分析表明,随着噻吗洛尔剂量增加,肾上腺素的作用呈线性减弱,最终使得联合用药的效果不如单独使用噻吗洛尔。
