Loop Diuretics · Pharmacology

Non-steroidal anti-inflammatory drugs (NSAIDs) can reduce the diuretic effect of Furosemide by inhibiting the synthesis of:

  1. Aldosterone
  2. Renin
  3. Prostaglandins
  4. Angiotensin II
Show answer and explanation

Correct answer: Prostaglandins

Prostaglandins, specifically PGE2, maintain renal blood flow and antagonize the effects of ADH. Loop diuretics stimulate PGE2 production; therefore, NSAIDs block this effect, leading to reduced renal perfusion and attenuated diuresis.
