There are several types of hypertension drugs.

Hypertension drugs are mainly divided into calcium antagonists, angiotensin converting enzyme inhibitors, angiotensin II receptor antagonists, diuretics and beta receptor blockers five types. 1, calcium antagonists calcium antagonists mainly through blocking calcium ion inflow, thereby relaxing vascular smooth muscle, reduce vasoconstriction, to achieve the effect of lowering blood pressure. Common drugs are nifedipine, fenodipine, lacidipine, etc. 2, angiotensin converting enzyme inhibitors angiotensin converting enzyme inhibitors mainly through the inhibition of systemic circulation aldosterone, thereby improving hemodynamics, reduce peripheral vascular resistance, to achieve the effect of lowering blood pressure, the main drugs are captopril, enalapril, perindopril and so on. 3. Angiotensin II receptor antagonist Angiotensin receptor antagonist mainly blocks vasoconstriction caused by angiotensin and promotes the secretion of aldosteroids to achieve the effect of lowering blood pressure. The main drugs are irbesartan, losartan, telmisartan, etc. 4. Diuretics Diuretics mainly reduce extracellular fluid volume and peripheral vascular resistance by inhibiting the reabsorption of sodium chloride by the kidneys, thus achieving the effect of lowering blood pressure. The main drugs are spironolactone, amiloride, hydrochlorothiazide, etc. 5, beta blockers beta blockers mainly by inhibiting excessive activity of sympathetic nerves, so as to achieve the effect of lowering blood pressure, the main drugs are atenolol, metoprolol, sotalol hydrochloride and so on.
