Anti-hypertensive medications lower blood pressure by reducing the heart's workload and come in various groups with distinct mechanisms of action. ACE inhibitors, ARBs, beta blockers, and calcium channel blockers are common types that aim to achieve the same goal of decreasing blood pressure while differing in side effects and how they work.
Insights
- ACE inhibitors work by preventing vessel constriction and aldosterone secretion, ultimately lowering blood pressure, while ARBs achieve a similar effect with fewer side effects like cough or angioedema.
- Beta blockers reduce heart rate and blood pressure by targeting beta 1 receptors, but side effects may include bradycardia, breathing problems, and lowered blood pressure, highlighting the importance of monitoring patients closely.

Recent questions
How do ACE inhibitors lower blood pressure?
ACE inhibitors inhibit the enzyme converting Angiotensin 1 to Angiotensin II, preventing vessel constriction and aldosterone secretion, leading to lower blood pressure.
What is the mechanism of action of ARBs?
ARBs block Angiotensin II receptors, similar to ACE inhibitors but with fewer side effects like cough or angioedema.
What are the side effects of beta blockers?
Beta blockers target beta 1 receptors, reducing heart rate and blood pressure, with side effects including bradycardia, breathing problems, and lowered blood pressure.
How do calcium channel blockers affect the heart?
Calcium channel blockers relax the heart by blocking calcium movement, decreasing heart workload and increasing oxygen supply, with medications like Verapamil, nifedipine, and diltiazem.
What is the common goal of anti-hypertensive medications?
The common goal of anti-hypertensive medications is to lower high blood pressure and manage chronic hypertension by decreasing the heart's workload.
