Which potassium-sparing effect does Losartan Potassium provide?

Losartan Potassium is an angiotensin II receptor antagonist, which means it works primarily by blocking the effects of angiotensin II, a hormone that can cause the kidneys to retain sodium and excrete potassium. By inhibiting this action, Losartan Potassium effectively promotes potassium retention. This is particularly beneficial in patients who are at risk of hypokalemia (low potassium levels) due to the use of other antihypertensive medications, such as diuretics, which can lead to potassium loss.

The role of Losartan in increasing potassium retention aligns with its mechanism of action, allowing it to help maintain appropriate potassium levels in the body. This characteristic makes it distinct from other antihypertensive classes that may lead to increased potassium excretion. Thus, the correct understanding is that Losartan Potassium directly contributes to the retention of potassium in the body.
