Abstract excerpt
The effects of a single 20 mg oral dose of timolol, a non-selective beta-adrenoceptor antagonist which is subject to hydroxylation in the liver, on intraocular pressure and heart rate were compared in four poor and five extensive debrisoquine metabolizers, using non-contact tonometry and bicycle ergometry. The beta blockade of timolol on exercise heart rate was significantly higher in poor than in extensive...
