In general, anti-hypertensive drugs can be divided into five major categories: 1, diuretic antihypertensive drugs (hydrochlorothiazide, spironolactone, furosemide). 2, sympathetic nerve inhibitors (a central antihypertensive drugs: such as colistin, rimantadine, etc.; b ganglion blockers: mecamylamine, etc.; c noradrenergic nerve terminal blockers: such as reserpine, guanethidine, etc.; d adrenergic receptor blockers: a receptor blockers: prazosin, phentolamine, etc.; beta receptor blockers: propranolol, metoprolol, carvedilol, etc.). 3, renin-angiotensin system inhibitors (a angiotensin-converting enzyme inhibitors (ACEI): such as perindopril, captopril, etc.; b angiotensin II receptor blockers (ARB): such as valsartan, candesartanate, etc.; c renin inhibitors: such as ramipril, etc.). 4, calcium antagonists (a dihydropyridines: nifedipine, amlodipine, etc.; b non-dihydropyridines: diltiazem, verapamil, etc.). 5, vasodilators (such as hydrazidiazine, sodium nitroprusside, etc.). Reminder: Anti-hypertensive drug treatment should be noted: 1, using a smaller effective dose. 2, it is best to use a day once a day and have a continuous 24-hour effect of the drug, to achieve a daily 24-hour blood pressure stability within the target range. 3, anti-hypertensive drug combination therapy, low-dose single species treatment is not satisfactory, you can use two or more anti-hypertensive drug combination therapy. 4, hypertensive patients need long-term regular medication treatment.
