Which medication class is indicated by the suffix "-zide"?

• A. Diuretics
• B. Beta blockers
• C. ACE inhibitors
• D. Antibiotics

Answer: (A)

The suffix "-zide" is typically associated with a specific class of medications known as diuretics, particularly thiazide diuretics. These medications work primarily by promoting the excretion of sodium and water through the kidneys, thus helping to reduce blood volume and lower blood pressure. Common examples include hydrochlorothiazide and chlorthalidone.

Diuretics are often utilized in the management of hypertension and edema associated with various conditions such as heart failure. They are effective in achieving fluid balance and alleviating symptoms related to excess fluid retention.

In contrast, beta blockers, ACE inhibitors, and antibiotics do not share this suffix. Beta blockers often end with "-olol," ACE inhibitors typically have names that end with "-pril," and many antibiotics can have a diverse range of suffixes that do not follow a particular pattern. Thus, recognizing the suffix "-zide" is key to identifying diuretics and their pharmacological role.
