Low blood pressure, also known as diastolic blood pressure, is not normal if it is 110 mmHg, and is relatively high. Patients are advised to make sure to identify the cause of the hypertension. If it is primary hypertension, long-term oral administration of relevant antihypertensive drugs is required to maintain a stable blood pressure. If the patient is mainly high diastolic blood pressure, the more advantageous choice of drugs is the antihypertensive drugs of the class of priligy or sartan, the representative drugs are Benadryl, Irbesartan, etc., which can relatively better reduce diastolic blood pressure. If the patient cannot control the blood pressure within the standard range by applying any of the above drugs alone, the patient should also combine the drugs, such as bisoprolol or metoprolol, and calcium channel blockers, such as felodipine and amlodipine. At the same time, lifestyle interventions should be combined with exercise and weight loss, low-salt and low-fat diet, regular work and rest, and a happy mood to better control blood pressure and delay the emergence of hypertension complications.
