Lamide medications function primarily as which type of inhibitor?

• A. Carbonic anhydrase inhibitor
• B. ACE inhibitor
• C. Diuretic
• D. Beta blocker

Answer: (A)

The main idea is that Lamide medications act by blocking the enzyme carbonic anhydrase. Carbonic anhydrase normally helps convert carbon dioxide and water into bicarbonate and hydrogen ions, a step important for reabsorbing bicarbonate in the kidney’s proximal tubule. When this enzyme is inhibited, less bicarbonate is reabsorbed along with sodium and water, leading to bicarbonate-rich urine (bicarbonaturia) and a mild diuretic effect. This mechanism defines them as carbonic anhydrase inhibitors. The diuretic effect is a consequence of the enzyme blockade, not the primary action itself. Other options describe different drug targets (ACE inhibition, beta-adrenergic blockade) or broad diuretic effects from other mechanisms, which don’t match the specific enzymatic target here.
