Betaxolol (trade names Betoptic Betoptic S Lokren Kerlone) is a selective beta1 receptor blocker used in the treatment of hypertension and glaucoma. 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.
