Commonly used antihypertensive drugs for hypertension are divided into five major categories, among which the most commonly used are four major categories: first, the Pulley class; second, the Diphenhydramine class; third, the Bisoprolol class; and fourth, diuretics. Hypertension according to the degree of blood pressure, the use of drugs are not exactly the same. If you have mild hypertension, which is hypertension grade 1, you can start with a drug in the priligy class, because mild hypertension can often be stabilized with one antihypertensive drug. Severe hypertension, that is, hypertension level 2 or hypertension level 3, at this time only taking a drug is not very effective, must be combined with two or more or three antihypertensive drug treatment, then you can choose to use two kinds of drugs, such as priligy and diphenhydramine. If the blood pressure is still high with these three drugs, Bisoprolol can also be added to combine four kinds of antihypertensive drugs.
