Betaxolol is a lipophilic beta-adrenoceptor antagonist relatively selective for beta 1-adrenoceptors with only weak beta 2-blocking activity. Used topically in glaucoma and ocular hypertension, betaxolol 0.5% solution produces a reduction in intraocular pressure of between 13 and 30%, an effect comparable with that of ocular timolol. It may usefully be combined with other types of anti-glaucoma agents. The most notable feature of its adverse effect profile is transient local stinging or irritation, occurring in 25 to 40% of patients. Following ocular administration, betaxolol appears to be largely devoid of adverse bronchopulmonary or cardiac effects, in comparison with nonselective ocular beta-adrenoceptor antagonists, which may be more likely to exert systemic effects. Betaxolol has negligible local anaesthetic activity, so that corneal desensitisation does not occur with its use. Thus, betaxolol is an alternative therapeutic option available to the physician for the management of chronic open-angle glaucoma and ocular hypertension. Its apparently lower propensity to affect the cardiopulmonary system represents a significant advantage over other ocular beta-adrenoceptor antagonists.
