Hypertension is currently a common and frequent disease, especially among middle-aged and elderly people. It requires the use of proper antihypertensive drugs to lower blood pressure back to a normal range to ensure the blood supply to the heart and brain. If medication is not taken on time, or due to emotional excitement or excessive fatigue, there can be a sudden increase in blood pressure. Immediate use of effective antihypertensive drugs is necessary to lower the blood pressure to a safe range to prevent accidents. In case of a hypertensive emergency, one should go to the hospital for active treatment to avoid life-threatening risks.
