Which class of medication does Valsartan belong to?

Valsartan is classified as an Angiotensin II receptor blocker (ARB), which identifies its primary mechanism of action in the treatment of various cardiovascular conditions, particularly hypertension and heart failure. As an ARB, Valsartan works by blocking the action of angiotensin II, a hormone that constricts blood vessels and raises blood pressure. By inhibiting this action, Valsartan promotes vasodilation, leading to a reduction in blood pressure and a decreased workload on the heart. This class of medication is particularly useful in patients who may experience cough as a side effect of ACE inhibitors or in those who exhibit heart failure, as it can improve outcomes and prevent hospitalizations.

Understanding this classification allows healthcare professionals to make informed decisions about pharmacological therapies, ensuring they select the most appropriate treatments based on the patient's specific condition and response to previous medications.
