What are the types of antihypertensive drugs?

1, calcium channel blockers calcium channel blockers include nifedipine, nimodipine, verapamil, etc., the principle of action is to relax vascular smooth muscle, reduce peripheral resistance, and achieve the purpose of lowering blood pressure. 2. Angiotensin-converting enzyme inhibitors Angiotensin-converting enzyme inhibitors include captopril, enalapril, benazepril, etc. The principle of action is to lower blood pressure by improving hemodynamics and reducing peripheral vascular resistance. 3, angiotensin receptor antagonists angiotensin receptor antagonists include losartan, valsartan, irbesartan, etc., the principle of action is to relax blood vessels, reduce peripheral resistance, in order to achieve the purpose of lowering blood pressure.4, diuretics Diuretics include furosemide, torasemide, hydrochlorothiazide, etc., the principle of action is to promote urination, reduce blood volume, to achieve the purpose of lowering blood pressure. 5. Beta blockers Beta blockers include propranolol, bisoprolol, atenolol, etc. The principle of action is to inhibit myocardial contraction and control heart rate, thus achieving the purpose of lowering blood pressure.
