Hypotension is also known as high diastolic blood pressure, the normal range of diastolic blood pressure is generally 60-89 mmHg, if the diastolic blood pressure ≥ 90 mmHg, it is considered elevated diastolic blood pressure. In this case, it is recommended to try to apply the antihypertensive drugs of the class of priligy or sartan, because these antihypertensive drugs have certain advantages in reducing diastolic blood pressure, and the representative drugs are enalapril, perindopril, irbesartan and telmisartan. In addition to the application of this type of antihypertensive drugs, calcium channel blockers as well as beta-blockers can also be applied in combination. Representative drugs of calcium channel blockers include amlodipine and felodipine, etc. Representative drugs of beta-blockers include metoprolol and bisoprolol, etc. In the case of primary hypertension, the condition of high low pressure cannot be cured, and treatment with drugs can only maintain blood pressure within the safe range or within the normal range, but cannot be completely cured.
