Certified Ophthalmic Medical Technologist (COMT) Practice Exam 2026 – Comprehensive All-in-One Guide to Success

Question: 1 / 505

Which type of agents are often referred to as beta-blockers?

Adrenergic agonists

Sympathomimetics

Sympatholytics

Beta-blockers are classified as sympatholytics because they work by blocking the effects of the sympathetic nervous system. Specifically, they inhibit the action of norepinephrine and epinephrine on beta-adrenergic receptors, which reduces heart rate, lowers blood pressure, and decreases ocular pressure, making them effective in treating conditions such as hypertension and glaucoma.

Understanding the function of sympatholytics is crucial, as these agents not only help manage cardiovascular issues but also play an important role in eye care, particularly in managing intraocular pressure in glaucoma patients. The terminology highlights the relationship between these agents and their mechanism of action within the sympathetic nervous system, which is essential knowledge for someone studying for the Certified Ophthalmic Medical Technologist (COMT) certification.
