How It Works

Furosemide inhibits Na-K-2Cl cotransporter in thick ascending limb of loop of Henle; Spironolactone competitively inhibits aldosterone in distal convoluted tubule, promoting Na and water excretion while retaining K

Mechanism Steps

1Furosemide binds to NKCC2 in thick ascending limb of loop of Henle
2Inhibits Na+, K+, Cl- reabsorption
3Increases osmotic gradient in medulla
