Core tip: Lao Ding is a hypertensive
Loading is an "old patient" of hypertension. With the advent of winter, whether the dosage of antihypertensive drugs needs to be adjusted? What are the differences in the medication of hypertensive patients in winter is his most concerned problem
Experts pointed out that in winter, the cold weather, peripheral blood vessels constriction, so that the peripheral resistance increased, blood pressure will be relatively high. Contrary to warm spring and summer, when the weather is warm, blood vessels dilate and blood pressure is easy to drop. Therefore, hypertension patients should adjust antihypertensive drugs in time according to blood pressure fluctuation in winter to ensure safe winter.
There are four principles for adjusting antihypertensive drugs in winter
1. If the patients with hypertension reduce the dose due to the decrease of blood pressure in summer, the dosage in winter should be restored to the original dose. If the dose is not reduced in summer, it is necessary to increase the dose according to the blood pressure in winter.
2. If a certain antihypertensive drug has reached the maximum dose, another antihypertensive drug should be used according to the physical condition, and the same drug dose should not be increased continuously. In this way, the blood pressure can be controlled satisfactorily and the adverse reactions caused by increasing the single antihypertensive drug dose can be relatively reduced.
3. Take time also has to pay attention to, should take antihypertensive drugs before the arrival of blood pressure peak.
Some patients with high blood pressure in the early morning should take antihypertensive drugs when they wake up every day. The blood pressure of patients with hypertension fluctuates greatly in the day and night, and the blood pressure will drop at night. If you take a lot of antihypertensive drugs before going to bed, the blood pressure is likely to be low and the blood flow is slow in the morning, which may lead to insufficient blood supply of Cardio cerebral vessels.
4. Patients with hypertension should be cautious to use two kinds of drugs in winter: diuretics - because the amount of drinking water is relatively reduced in winter, if large doses of diuretics are used, the body will lose a lot of water, which will easily lead to the increase of blood viscosity, thus increasing the risk of thrombosis; short-acting and quick-acting antihypertensive drugs such as nifedipine (nifedipine).
Some patients have the habit of temporary rapid hypotension when their blood pressure rises. However, they do not know that short-acting and rapid antihypertensive drugs will make blood pressure drop sharply in a short time, which will lead to sudden decrease of blood supply to brain or heart and induce stroke or angina pectoris, which is very dangerous.
Experts suggest: Patients with hypertension can choose sustained-release tablets to reduce blood pressure in winter. In addition, experts also remind readers that patients with hypertension and coronary heart disease must exercise in the morning after the sun comes out.
Early morning exercise, because the temperature is too low, indoor and outdoor temperature difference is very large, sudden cold will make blood vessels suddenly contract, lead to rapid rise in blood pressure, may cause angina pectoris attack. Do not face the door and window when opening the door and window in the morning to avoid sudden contact with cold air.
