Which suffix indicates diuretic agents?

• A. Mide
• B. Pril
• C. Done
• D. Vir

Answer: (A)

Recognizing how drug name endings signal their class helps you identify diuretic agents. The suffix -mide is characteristic of loop diuretics, with examples like furosemide, torsemide, and bumetanide. These drugs work by inhibiting the Na+-K+-2Cl- cotransporter in the thick ascending limb of the loop of Henle, which reduces reabsorption of sodium and chloride and increases urine output. The other endings point to different drug classes: -pril are ACE inhibitors, -vir is typical for antivirals, and -done is not a standard diuretic suffix. So the diuretic suffix is -mide.
