Webmultiple mechanisms through which diuretic resistance can occur, including the “braking” phenomenon where decreased diuresis occurs with repeated doses of loop diuretics, the post-diuretic effect in which sodium reabsorption at the loop of Henle increases once the loop diuretic has worn off, and nephron remodeling including hypertrophy of ... WebLoop diuretics reduce sodium chloride reabsorption in the thick ascending limb of the loop of Henle. This is achieved by inhibiting the Na-K-2Cl carrier in the luminal membrane in this segment, thereby minimizing the entry of luminal sodium and chloride into the cell ( figure 1) [ 1 ]. The loop diuretics are highly protein bound and therefore ...
