Normal blood pressure during the day and elevated blood pressure at night are also considered high blood pressure and need to be treated with oral antihypertensive medication. If oral antihypertensive drugs have been taken, it means that the dosage of antihypertensive drugs is not enough, or the time of taking the drugs makes the antihypertensive effect unable to be maintained at night, thus the blood pressure rises at night. In order to better understand the situation of blood pressure, you can do a 24-hour ambulatory blood pressure examination, to understand in detail the pattern of blood pressure changes over time, to better choose antihypertensive drugs and determine the time to take medication. The commonly used clinical antihypertensive drugs are amlodipine, nifedipine controlled release tablets, irbesartan, enalapril, or single tablet compound preparation, including valsartan, amlodipine, irbesartan, hydrochlorothiazide. Along with the medication, it is important to maintain a good lifestyle.
