There are five types of antihypertensive drugs recommended for primary hypertension: diuretics (e.g., tachycardia, hydrochlorothiazide, etc.), β-receptor antagonists (e.g., propranolol), calcium channel blockers (e.g., nifedipine tablets), angiotensin II receptor antagonists (e.g., valsartan, etc.), and angiotensin-converting enzyme inhibitors (e.g., perindopril), which should be regulated by a doctor’s guidance. The application of antihypertensive drugs should follow the principle of individualization, i.e., physicians should select suitable antihypertensive drugs according to the patient’s specific conditions such as the underlying disease, the effectiveness and tolerability of the drugs, as well as taking into account the patient’s economic conditions and personal wishes. Therefore, the medication recommendations for essential hypertension may include all types of antihypertensive drugs, but should be taken under the guidance of a physician. The combination of various underlying diseases will result in different treatment programs; the combination of different drugs will also result in different drug regimens. Therefore, primary hypertension needs to go to the hospital for standardized diagnosis and treatment, and the recommended medication includes all the above classes of drugs, but the medication should be taken according to the doctor’s instructions, and should not be used without authorization.
