Clinical selection of antihypertensive drugs is individualized differences, should be based on each person’s different circumstances using different drugs, generally commonly used drugs include β-blockers, calcium antagonists, diuretics, and ACEI/ARB class. 1. β-blockers: such as atenolol, metoprolol and so on. Especially for patients with tachyarrhythmia and coronary artery disease, β-blockers have the effect of slowing down the heart rate, which can slow down the heart rate and lower blood pressure at the same time. However, they are not suitable for patients with asthma. 2. Calcium antagonists: such as nifedipine, amlodipine and so on. Especially suitable for the elderly hypertension (simple systolic hypertension), and patients with angina pectoris. However, calcium antagonists are contraindicated in patients with heart failure. 3. Diuretics: such as hydrochlorothiazide, antitussive and so on. They are commonly used antihypertensive drugs. By lowering the circulating blood volume, the blood pressure is lowered. Because of the specificity of its mechanism of action, it is generally used in small doses. Long-term use of diuretics can lead to low potassium, it is recommended to combine with potassium-preserving diuretics. 4. ACEI/ARB (Angiotensin Converting Enzyme Inhibitor/Angiotensin Receptor Inhibitor): e.g. Captopril, Chlorosartan, etc. These two types of drugs work by blocking the blood vessels. These two types of drugs are by blocking the role of angiotensin to achieve the purpose of lowering blood pressure. Blood creatinine values should be noted when using them. For hypertension, a chronic disease, it is recommended to go to a regular hospital for treatment, and choose the right medication for yourself according to your doctor’s guidance.
