Final answer:
Betaxolol is the prescribed beta-adrenergic blocker for clients with glaucoma. It reduces intraocular pressure by blocking ß1-receptors in the eye. Other beta-blockers, like metoprolol and propranolol, are primarily used for cardiovascular diseases.
Step-by-step explanation:
In the context of glaucoma treatment, the beta-adrenergic blocker prescribed is betaxolol. Beta-blockers are typically associated with the treatment of cardiovascular diseases by blocking beta receptors, which can lead to a reduction in heart rate and blood pressure. Specifically, betaxolol works by blocking the ß1-receptors in the eye, thereby reducing intraocular pressure, a key factor in the management of glaucoma. Other beta-blockers like metoprolol and propranolol are more commonly associated with heart conditions, as they prevent the effects of adrenaline on the heart, thus reducing the workload on the heart and helping to control heart rate and blood pressure. Glaucoma treatment represents a specialized application where certain beta-blockers can uniquely benefit the condition by lowering intraocular pressure.
