Angiotensin II Receptor Blockers (ARBs)_ Mechanism of Action, Mnemonic, Side Effects, Indications

Welcome to our educational video on Angiotensin II Receptor Blockers (ARBs). In this video, we'll delve into the mechanism of action, mnemonic for easy recall, common side effects, and indications of ARBs.

1. Mechanism of Action:
ARBs work by blocking the action of angiotensin II at the receptor level, specifically the angiotensin II type 1 (AT1) receptors. By doing so, they prevent angiotensin II from exerting its vasoconstrictive and aldosterone-stimulating effects. This leads to vasodilation, decreased blood pressure, and reduced sodium retention.

2. Mnemonic for Recall:
To remember the names of commonly prescribed ARBs, you can use the mnemonic "SARTAN":

S - Losartan
A - Azilsartan
R - Telmisartan
T - Irbesartan
A - Valsartan
N - Eprosartan
3. Side Effects:
Common side effects of ARBs include dizziness, hypotension (low blood pressure), hyperkalemia (high potassium levels), and renal impairment. Additionally, some individuals may experience cough or angioedema, though these are less common compared to ACE inhibitors.

4. Indications:
ARBs are primarily indicated for the management of hypertension (high blood pressure). They are also used in the treatment of heart failure, diabetic nephropathy, and for the prevention of stroke and cardiovascular events in patients at high risk.

Understanding the mechanism of action, remembering the names with the mnemonic, being aware of potential side effects, and knowing the indications will help healthcare professionals in making informed decisions regarding the use of ARBs in clinical practice.
