Chapter 155 Antihypertensive drugs should not be taken before going to bed

Some patients think that taking antihypertensive drugs before going to bed can make them sleep comfortably.

As everyone knows, taking antihypertensive drugs before going to bed is not only unscientific, but also easily induces cerebral thrombosis, angina pectoris and myocardial infarction, causing serious consequences.

This is because the human body is regulated by its own "biological clock", and blood pressure fluctuates greatly within 24 hours.After falling asleep, most of the body is in a resting state, the metabolism slows down, and the blood pressure also decreases accordingly, and it can be reduced by about 2% by 20 hours after going to bed.If you take antihypertensive drugs before going to bed, 2 hours later is the high-efficiency period of the drugs, which will lead to a sharp drop in blood pressure and insufficient blood supply to the heart and brain.In addition, because the blood pressure is too low and the blood flow is slow, it is easy to cause blood clots. If the blood clot blocks the blood vessel, it will cause embolism.Therefore, hypertensive patients must take the medicine according to the prescribed time, and the last medicine of the day should be taken 3 to 4 hours before going to bed.

When taking antihypertensive drugs, pay attention to the following two points:

1. Do not use or stop taking antihypertensive drugs at will.In addition to the antihypertensive effect, antihypertensive drugs also have the effects of reducing arteriosclerosis and protecting heart function.All of these require a certain amount of medication time and action process.Therefore, the medication must be adhered to according to the course of treatment.

2. After obtaining a satisfactory antihypertensive effect with antihypertensive drugs, the dosage should be gradually reduced to the maintenance dosage in time, and the medication should be maintained for half a year to more than one year.
