Video animation on renal physiology and diuretics mechanism of action.
Mechanism of action of loop diuretics ( Source: Bertram Katzung, Basic and Clinical Pharmacology, Mc Graw Hill Medical, 2007): Pharmacodynamics These drugs inhibit NKCC2, the luminal Na+/K+/2Cl– transporter in the thick ascending limb of Henle’s loop. By inhibiting this transporter, the loop diuretics
