High blood pressure symptomatic antihypertensive drugs, antihypertensive effect is the best, food can only help to adjust blood pressure, can not lower blood pressure. The commonly used antihypertensive drugs for hypertension mainly include diuretics, calcium antagonists, beta-blockers, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers and so on, which are suitable for different people. 1. Diuretics: including such as indapamide, spironolactone, hydrochlorothiazide, etc., which can lower blood pressure by reducing blood volume through diuresis and sodium excretion. However, electrolytes and renal function need to be monitored. 2. Calcium antagonist to lower blood pressure: commonly used drugs such as chlordiazepoxide, nifedipine, felodipine, etc., through inhibiting the flow of calcium ions in vascular smooth muscle, so as to achieve the effect of vasodilatation and lowering blood pressure. Such drugs are suitable for patients with hypertension combined with angina pectoris and cerebral infarction. 3. β-blockers: commonly used drugs such as propranolol and metoprolol. This kind of drugs lowering blood pressure while lowering the heart rate effect is good, side effects are small, for the respiratory tract bronchial impact is small. And long-term use of blood glucose, blood fat has little effect, suitable for patients with hypertension with coronary heart disease. 4. Angiotensin-converting enzyme inhibitors: commonly used, such as captopril, benazepril and so on. By inhibiting the activation of angiotensin-converting enzyme, it can achieve the purpose of relaxing blood vessels and lowering blood pressure. 5. Angiotensin II receptor blockers: commonly used drugs such as valsartan, irbesartan, timosartan, etc., also inhibit the role of angiotensin, so as to achieve vasodilatation, the purpose of lowering blood pressure. It should be noted that patients with hypertension should strictly follow the doctor’s instructions for medication, and should not take medication, reduce medication, stop medication, etc. without authorization.
