Classification and Selection of Commonly Used Antihypertensive Drugs

At present, commonly used antihypertensive drugs are mainly divided into five categories, namely calcium ion antagonists, ACEI drugs, ARB drugs, beta blockers and diuretics, which are generally selected according to the individual conditions of patients. 1. Calcium ion antagonists such as amlodipine, nifedipine, felodipine, etc., which can increase the delivery of myocardial itch and reduce myocardial metabolism, are generally suitable for patients with essential hypertension, especially patients with coronary heart disease and angina pectoris. 2. ACEI drugs such as benazepril, enalapril, perindopril, etc. are angiotensin converting enzyme inhibitors, which can dilate blood vessels and reduce the burden on the heart. These drugs are mainly used in patients with hypertension such as coronary heart disease and heart failure. 3. ARB drugs such as candesartan, valsartan, losartan potassium, etc., are angiotensin II receptor antagonists, because they can inhibit the excitability of sympathetic nerves, so they can achieve the effect of lowering blood pressure, but such drugs are mainly used clinically in patients with hypertension such as coronary heart disease, stroke and peripheral vascular disease. 4, beta blockers such as metoprolol, bisoprolol, atenolol, etc., these drugs can slow down the heart rate, effective control of blood pressure. Such drugs are mainly used in patients with high diastolic blood pressure, hypertension in young people or patients with coronary heart disease. 5. Diuretics such as hydrochlorothiazide, furosemide, torasemide, etc., which reduce blood volume through diuresis, thus effectively controlling blood pressure. These drugs are mainly used in patients with mild to moderate hypertension.
