What is a common side effect of ARBs?

Angiotensin II receptor blockers (ARBs) are commonly used medications for managing hypertension and heart failure, and one of their well-documented side effects is hyperkalemia, which is an elevated level of potassium in the blood. ARBs work by blocking the effects of angiotensin II, leading to vasodilation and reduced secretion of aldosterone. Aldosterone plays a key role in maintaining sodium and potassium balance in the body. When aldosterone levels are reduced due to ARB therapy, the kidneys may excrete less potassium, resulting in increased potassium levels, or hyperkalemia.

Monitoring potassium levels is important in patients taking ARBs, especially those with pre-existing conditions like chronic kidney disease or those on other medications that may also raise potassium levels. Hyperkalemia can lead to serious cardiac issues if not managed properly, so awareness of this side effect is crucial for healthcare providers.

The other options, such as weight gain, dry mouth, and bradycardia, are not commonly associated side effects of ARBs. Weight gain may be seen with certain medications like antidepressants or corticosteroids, while dry mouth is more commonly linked to medications with anticholinergic effects. Bradycardia is typically related to beta-blockers or certain calcium channel
