Introduction: “At this stage, hypertension is at a high incidence, and patients may take medication based on their feelings, intermittently, without taking medication without symptoms, and choose their own medication time resulting in poor blood pressure control. So how do doctors choose hypertension medications? And what are the types of hypertension drugs?” Hypertension is a disease of persistent high blood pressure, which can cause stroke, heart disease, etc. Hypertension is a systemic disease characterized by elevated arterial pressure, which can be accompanied by functional or organic changes in organs such as the heart, blood vessels, brain and kidneys, and it has primary hypertension and secondary hypertension. There are many causes of hypertension, which can be divided into two aspects: genetic and environmental. First of all, hypertension medication first eliminate: 1, random medication by feeling; 2, intermittent random medication; 3, no symptoms do not take medication; 4, self-selection of medication time, follow the doctor’s orders is the key. Secondly, the goal of lowering blood pressure: we have to control blood pressure through drugs to 140/90mmHg or less in patients with common hypertension, and systolic blood pressure to 150mmHg or less in the elderly. Patients with diabetes and kidney disease should be controlled to below 130/80. Antihypertensive drug therapy (a) angiotensin-converting enzyme inhibitors: current applications: mercaptomethoproline, enalapril, etc.; (b) calcium antagonists: they inhibit the inward flow of calcium ions through calcium channels on the cell membrane, and are therefore called calcium channel antagonists. Commonly used drugs are: isoptin, thioprostone and nifedipine, nicardipine, etc.; (c) vasodilators: directly relax vascular smooth muscle, dilate blood vessels and lower blood pressure; commonly used drugs are: 1. sodium nitroprusside; 2. long pressure; 3. hydrazinebendazide. (iv) antihypertensive drugs that act on the sympathetic nervous system. 1, central sympathetic nerve inhibitors: colistin; methyldopa; 2, sympathetic ganglion blockers: commonly used drugs such as Alfannate; 3, post-sympathetic ganglion blockers: the sympathetic nerve terminals in norepinephrine storage depletion, and the purpose of lowering blood pressure. Commonly used drugs are: guanethidine; reserpine; 4, adrenergic receptor blockers: β-blockers, liubamide benzathine is the WHO recommended antihypertensive drugs. Vinblastine; α-blockers: commonly used are doxazosin. (E) diuretic antihypertensive drugs. 1, thiazide: is the most widely used oral diuretic antihypertensive drugs, dihydroketuria; mostly used in elderly hypertension, simple systolic hypertension; 2, tab diuretics; renal insufficiency, congestive heart failure commonly used; 3, anti-aldosterone drugs; congestive heart failure, post-infarction use, renal insufficiency, hyperkalemia is prohibited.
