Which class of medications increases urine production?

• A. Anticholinergics
• B. Diuretics
• C. Analgesics
• D. Alpha blockers

Answer: (B)

Increasing urine production is achieved by diuretics, which act on the kidneys to promote the excretion of sodium and water. By blocking reabsorption of electrolytes in different parts of the nephron, they raise the amount of urine produced and help reduce fluid overload, which is why they’re used for conditions like hypertension, edema, and heart failure. Anticholinergics slow bladder activity and can cause urinary retention, so they don’t increase urine output. Analgesics don’t inherently boost urine production and, in some cases, can affect kidney function in ways that reduce urine. Alpha blockers relax certain smooth muscles to ease urine flow but don’t increase the volume of urine produced. So the class that increases urine production is diuretics.
