Betaxolol is best described as which type of blocker?

Explanation:
Betaxolol works by blocking beta-1 adrenergic receptors, which are mainly in the heart. By inhibiting these receptors, it lowers heart rate and the force of contraction. As an eye drop, this action reduces aqueous humor production, lowering intraocular pressure. The label “beta-1 selective” means it preferentially blocks beta-1 receptors over beta-2 receptors, so it carries a lower risk of beta-2–mediated bronchoconstriction compared with nonselective beta blockers. It is not an alpha blocker and does not primarily target beta-2 receptors.
