Both high pressure and low pressure are clinical manifestations of hypertension, which can be treated with antihypertensive drugs as long as the diagnosis of the disease is confirmed, and the specific use of drugs must follow the doctor’s instructions. If the systolic blood pressure (high pressure) ≥140mmHg and/or diastolic blood pressure (low pressure) ≥90mmHg more than three times on the same day, it is called hypertension, therefore, even if the high pressure and the low pressure are both abnormal, it is only treated as one kind of disease, and the same antihypertensive drugs can be taken. Currently, commonly used antihypertensive drugs include diuretics (e.g., hydrochlorothiazide), beta-blockers (e.g., metoprolol), and calcium channel blockers (e.g., nifedipine). However, it should be noted that the therapeutic effects of various antihypertensive drugs are still affected by multiple factors such as individual physical condition, drug compliance, and severity of the disease, and the specific efficacy varies from person to person, with different contraindications and adverse effects. Therefore, those who have been diagnosed with hypertension must use antihypertensive drugs under the guidance of a doctor, and must not blindly use drugs or increase or decrease the dosage of drugs on their own, so as not to cause adverse consequences.
