Potassium and Valsartan, a conflict.
Valsartan blocks AT1 receptors, reducing aldosterone and potassium excretion. Potassium supplementation creates hyperkalemia risk.

Conflict
What is happening. Valsartan blocks AT1 receptors, reducing aldosterone and potassium excretion. Potassium supplementation creates hyperkalemia risk.
Mechanism. AT1 receptor blockade in the adrenal cortex reduces aldosterone release, decreasing renal potassium secretion in the collecting duct.
Recommendation. Avoid potassium supplements with valsartan unless prescribed with close monitoring.
