Betaxolol (trade names Betoptic, Betoptic S, Lokren, Kerlone) is a selective beta1 receptor blocker used in the treatment of hypertension andglaucoma. Being selective for beta1 receptors, it typically has fewer systemic side effects than non-selective beta-blockers, for example, not causing bronchospasm (mediated by beta2 receptors) as timolol may. Betaxolol also shows greater affininty for beta1 receptors than metoprolol. |
