There is no such thing as which antihypertensive drug is effective and has fewer side effects. Hypertensive patients need to choose the appropriate drug and corresponding scientific treatment plan according to their specific conditions under the guidance of specialists. There are five major types of antihypertensive drugs in common use, namely, diuretics (e.g. hydrochlorothiazide, spironolactone, furosemide), beta-blockers (e.g. metoprolol), calcium channel blockers (e.g. nifedipine, amlodipine), angiotensin-converting enzyme inhibitors (e.g. captopril, fosinopril), angiotensin receptor antagonists (e.g. irbesartan), and so on. 1. Primary hypertension needs to be selected according to the condition and the body’s response to the drugs and other factors for comprehensive consideration, some patients can be used alone, while some need to be combined with drugs. 2. Secondary hypertension has a variety of causes. Such as primary aldosteronism, pheochromocytoma, acute glomerulonephritis, nephrotic syndrome, renal artery stenosis, Cushing’s syndrome, etc., should be given as early as possible to remove the cause of the treatment, the means of treatment may be medication, may also be surgery. 3. Regardless of which antihypertensive treatment is chosen, a scientific and healthy lifestyle should always be carried through, such as low-salt and low-fat diet, quitting smoking and restricting alcohol, appropriate physical exercise, weight control, and maintaining mental health. In short, hypertension patients need to be treated under the guidance of specialists, and should not take antihypertensive drugs on their own.
