Title: Re: Why do patients taking loop diuretics need to take supplemental potassium? Post by: suzy587423 on Jun 7, 2014 I believe the answer is B In the ascending limb of the loop of Henle, there exists a Na+/K+/2Cl- cotransporter. This cotransporter takes sodium and potassium back up out of the urine and secretes chloride into it. Loop diuretics block this cotransporter. |
