China is the world's largest number of hypertension patients, by the mainland eating habits, the pace of life accelerated and lifestyle changes, national aging and other aspects of the impact, in recent years the prevalence of hypertension soared, and gradually showed a trend of rejuvenation, the total number of people in the mainland reached nearly 300 million.
And because the symptoms of hypertension are not typical in the early stage, so far nearly 1/2 of patients with primary hypertension have not been diagnosed.
The so-called primary hypertension refers to the unclear etiology, due to a number of comprehensive factors caused by increased blood pressure, it occupies about 90% of all hypertensive patients.
So far, there is no cure for hypertension in mainland china clinics, so as long as this hypertension is diagnosed, the first thing patients have to do is to start medication treatment.
However, there are many precautions for taking antihypertensive drugs, especially the following four cannot be ignored:
1. Dose control
When patients with hypertension first use antihypertensive drugs, if the one-time dose is too large, the patient is likely to have uncomfortable symptoms, such as palpitations, chest tightness and shortness of breath.
In particular, some elderly patients with hypertension are not sensitive to the pressure reflex themselves, and the automatic regulation of cerebral blood vessels often appears to be impaired, so it is impossible to blindly use large doses of drugs.
In the initial stage of taking drugs in patients with hypertension, a small dose should be taken to start, that is, about 1/3 of the commonly used amount, and then gradually increase to the appropriate medicinal dose to give the body time to adapt to the drug;
2, can not be arbitrarily stopped
We should clearly realize that the normal blood pressure after taking antihypertensive drugs is not the result of the disease being cured, but the result of the antihypertensive drugs still working in the body.
If the drug is blindly stopped and the dosage is reduced at will, it will not take long for the patient's blood pressure to rebound again, and there may be discontinuation syndrome, accompanied by symptoms such as sweating headache, insomnia, anxiety and agitation.
Studies have shown that almost all antihypertensive drugs have discontinuation syndrome. Therefore, as long as the antihypertensive drug is started, the patient cannot stop the drug at will;
3. Drugs cannot be changed at will
Hypertension is originally a long-term chronic disease, so its control is also a long-term process, from the beginning of medication to the stabilization of the condition, it takes a certain amount of time.
At this stage, patients cannot change drugs at will, because the severity and age of different patients are different, and the mechanism of action of different antihypertensive drugs is also different, and those suitable for others may not really be suitable for themselves. The consequences of blindly changing drugs will only make blood pressure fluctuate repeatedly and make it more and more difficult to control;
4. Pay attention to the medication time
There are several types of antihypertensive drugs, and different types of antihypertensive drugs vary in duration, mechanism of action, and half-life. When the patient begins medication treatment, the doctor should be consulted in detail about the specific medication time, and there is excellent medication compliance, do not take it arbitrarily.
In particular, blindly taking antihypertensive drugs before going to bed at night may cause a significant drop in blood pressure, and even a sudden risk of cardiovascular and cerebrovascular diseases.
Finally, it should be emphasized that as long as patients with hypertension start taking drugs, it is basically long-term, or even lifelong. In order to fully stabilize blood pressure, what patients can do is to actively follow the doctor's advice and arrangements, and measure blood pressure regularly and regularly during the medication process.
If it is found that after a period of medication, the blood pressure has not dropped, you should consult a doctor in time to see if you need to adjust the medication or combine the medication.
