Clinically, the commonly used drugs for the initial stage of hypertension include propranolol, hydrochlorothiazide and nifedipine. In current clinical practice, patients with high blood pressure of the second level or above, patients with high blood pressure accompanied by damage to the brain, heart, kidney and other organs, and people with persistently elevated blood pressure who are ineffective in general treatment need to be given antihypertensive drugs for standardized clinical treatment. The more common antihypertensive drugs include diuretic hydrochlorothiazide, beta receptor antagonist metoprolol, calcium channel blocker nifedipine, angiotensin-converting enzyme inhibitor captopril, angiotensin receptor blocker chlorosartan and so on. If hypertension exists, it is recommended to standardize the treatment under the guidance of a doctor to avoid delays in delaying the condition.
