Which medication suffix indicates a category of drugs used for controlling blood pressure?

• A. -statin
• B. -olol
• C. -sone
• D. -zide

Answer: (B)

The suffix "-olol" is indicative of a class of medications known as beta-blockers. These drugs are primarily utilized for managing a variety of cardiovascular conditions, including hypertension (high blood pressure). Beta-blockers work by inhibiting the effects of adrenaline on beta-adrenergic receptors, which leads to a decrease in heart rate and myocardial contractility. This ultimately results in lowered blood pressure and reduced strain on the heart.

In the context of pharmacology, recognizing drug suffixes can greatly aid in identifying the uses and effects of medications. For instance, "-statin" medications are aimed at lowering cholesterol, while "-sone" typically refers to corticosteroids involved in inflammation and immune response, and "-zide" is associated with a class of diuretics that also lower blood pressure but through different mechanisms than beta-blockers. Understanding these suffixes enhances the ability to classify and predict the actions of various pharmacological agents.
