ليه فاعلية الـThiazide diuretics بتقل في حالة renal failure patient؟

🚨 Thiazide diuretics' effectiveness decreases in renal failure due to their action on the distal convoluted tubule, which requires functional renal tubules.

💧 These diuretics work by inhibiting the reabsorption of sodium and chloride ions.

📉 In renal failure, especially with reduced glomerular filtration rate (GFR), there's insufficient delivery of these electrolytes to the distal tubule, which limits the diuretic effect.

🔄 As renal function declines, the kidneys become less effective at filtering and processing thiazide diuretics, reducing their diuretic response.

⚠️ For patients with significant renal impairment, loop diuretics are generally preferred because they remain effective even with lower GFR levels.
