High blood pressure medication is mainly based on the level of blood pressure fluctuations to decide, due to each patient’s blood pressure fluctuations are different, the time to take medication to follow the principle of individualization.
Controlled by the biological clock, each person’s blood pressure will appear “two peaks and one valley” phenomenon, “two peaks” one in the morning, one in the afternoon; “one valley” nighttime blood pressure, under normal conditions. Nighttime blood pressure is low, the rate of decline is about 10% to 20%, medically known as “spoon blood pressure”.
1. For antihypertensive drugs that need to be taken only once a day, most of them are taken at 7:00 am. These antihypertensive drugs can control the “morning peak” blood pressure.
2. For antihypertensive medications that need to be taken twice a day, the appropriate time to take the medication is at 7:00 am and 4:00 pm.
3. For short-acting antihypertensive drugs that are to be taken 3 times a day, the appropriate time to take the drugs is at 7 a.m., 1 p.m. and 4 p.m.
Of course, hypertensive patients each have different individual conditions and need to monitor their blood pressure to understand the fluctuation of blood pressure. Generally, the onset of action of medium- and long-acting antihypertensive drugs is 2 hours after taking the medication. By monitoring blood pressure, the doctor will formulate an individualized dosing principle for the patient and take the antihypertensive drugs 1~2 hours before the peak of blood pressure.
If the patient’s blood pressure drops more than 20% at night compared to the daytime, the blood pressure is at a low level at night, and if the antihypertensive drug is taken before bedtime, it will easily lead to a significant drop in blood pressure, resulting in insufficient blood supply to the heart, brain, kidneys and other organs. Patients must monitor their blood pressure, understand the characteristics of blood pressure, and take oral antihypertensive drugs as prescribed by the doctor.
