Which increases urine excretion?

Explanation:
Diuretics raise urine production by promoting the kidneys’ excretion of water and electrolytes. They work by reducing sodium (and hence water) reabsorption along parts of the nephron, so more fluid leaves as urine. For example, loop diuretics block the Na-K-2Cl transporter in the thick ascending limb, thiazide diuretics inhibit NaCl reabsorption in the distal tubule, and potassium-sparing diuretics affect sodium handling in the collecting ducts. This renal effect directly increases urine volume. The other drug types have different primary uses: antivirals target viruses, emetics induce vomiting, and expectorants help clear mucus from the airways.
