Hypertension is also considered when a hypertensive patient has low high pressure and high low pressure. Diagnosing hypertension means that regardless of high pressure or low pressure, as long as it is elevated, it is considered hypertensive. Once a hypertensive patient has elevated low pressure, it suggests that it may be mainly atherosclerosis or sympathetic overexcitation that leads to elevated blood pressure. The first is nifedipine and felodipine, which are drugs whose main antihypertensive effect is to dilate blood vessels and lower low pressure. If oral nifedipine is not effective, you can also add bisoprolol, metoprolol succinate and other drugs. These drugs are beta-blockers, which have the effect of reducing sympathetic excitability and can also lower low pressure. However, all antihypertensive drugs lower both high and low pressure, only the above two drugs are applied when low pressure is elevated, low pressure is lowered more obviously, but taking them will also make high pressure lower.
