Betaxolol hydrochloride

Definition

Betaxolol hydrochloride is a beta-1 adrenergic receptor blocker used primarily to reduce intraocular pressure in patients with glaucoma or ocular hypertension. It works by decreasing the production of aqueous humor in the eye.

5 Must Know Facts For Your Next Test

1. Betaxolol hydrochloride is often prescribed for open-angle glaucoma and ocular hypertension.
2. It selectively blocks beta-1 receptors, minimizing respiratory side effects compared to non-selective beta blockers.
3. Commonly administered as an ophthalmic solution, typically at a concentration of 0.25% to 0.5%.
4. Patients should be monitored for potential systemic effects like bradycardia and hypotension despite its local administration.
5. Contraindicated in patients with sinus bradycardia, heart block greater than first degree, cardiogenic shock, and overt cardiac failure.
