A diastolic blood pressure of 100 mmHg has met the diagnostic criteria for grade 2 hypertension. For people with increased diastolic blood pressure, the antihypertensive drugs that can be chosen are calcium channel antagonists, like nifedipine extended-release tablets or controlled-release tablets and amlodipine, etc. Drugs like ARBs, such as valsartan and irbesartan, can also be chosen, as well as diuretics, such as hydrochlorothiazide and indapamide, etc., can also be chosen. Drugs such as metoprolol can also be added if there is a combination of fast heart rate. If the patient has no other complications, these drugs can be chosen, but the recommended ones are compound preparations, such as valsartan hydrochlorothiazide tablets and valsartan amlodipine tablets, which are effective in lowering blood pressure to the normal range. If there is severe renal insufficiency, try not to use ARB drugs. You must also pay attention in your normal life, measure your blood pressure once a day in the morning and evening, and at least reduce your blood pressure to below 140/90mmHg.
