There are five types of antihypertensive drugs, namely diuretics, beta receptor antagonists, calcium channel blockers, angiotensin-converting enzyme inhibitors, and angiotensin II receptor antagonists. Due to individual differences, there is no such thing as which one is the best or which brand is good to use, and the most appropriate drug should be selected under the guidance of the doctor in combination with the patient’s condition. 1. Diuretics: reduce extracellular volume through urination. Specific drugs include hydrochlorothiazide, furosemide, spironolactone and so on. 2. β-receptor antagonists: slow down the heart rate by inhibiting the central, myocardial contractility. Specific drugs include propranolol, metoprolol and so on. 3. Calcium channel blockers: reduce vascular resistance by decreasing calcium ions entering cells. Specific drugs include nifedipine and nicardipine. 4. Angiotensin-converting enzyme inhibitors: specific drugs include captopril, enalapril, and so on. 5. Angiotensin II receptor antagonist: specific drugs are valsartan, irbesartan and so on. Remind patients: the above drugs need to be taken under the guidance of a doctor.
