Investigation shows that nearly 1/3 of patients taking antihypertensive drugs, complaining of poor drug effects, however, clinical observation of many kinds of antihypertensive drugs, the antihypertensive efficiency of up to 80% to 90%, then, what is the reason for this? 1, the choice of drugs is not the right antihypertensive drugs, many types of antihypertensive drugs, and the role of each antihypertensive drugs and applicable objects are not very consistent. Some antihypertensive drugs are effective for this type of hypertension, but not necessarily effective for another type of hypertension. If you do not see any effect after taking antihypertensive drugs, you may not have chosen the right drug. Therefore, hypertensive patients should be under the guidance of a doctor, the choice of appropriate drugs, the right medicine to be effective. 2, the dose of drugs used inappropriate hypertension patients choose antihypertensive drugs, should be adjusted according to changes in blood pressure drug dose. The dose of antihypertensive drugs depends on the blood pressure, therefore, every hypertensive patient is using antihypertensive drugs, blood pressure should be measured at least once a week, each measurement of blood pressure is best carried out at the same time, 20 minutes of meditation before measurement, otherwise, if the blood pressure measurement is not accurate, it is impossible to adjust the drug dose. 3, the use of antihypertensive drugs single Some intractable hypertension is not sensitive to antihypertensive drugs, often need a variety of antihypertensive drugs in combination, if the use of a single drug, it is bound to be difficult to achieve better antihypertensive effect. 4, can not continue to rational use of drugs about 1/3 of the patients can not adhere to the daily medication. They tend to feel headache, dizziness on the medication, in fact, hypertensive patients vary greatly in self-perceived symptoms, some blood pressure is quite high, there are no obvious symptoms, therefore, should not be based on their own subjective feelings to take medication. 5, randomly changing antihypertensive drugs wrong, but should follow medical advice to take medication. 6, purely rely on antihypertensive drugs Some patients rely solely on drugs to lower blood pressure, thinking that after taking antihypertensive drugs do not need to care about anything, playing mahjong, poker, watching TV, etc. for too long, so that the spirit of long-term tension, some continue to smoke, drink alcohol, drink strong tea and coffee, fatty meat and other greasy food as usual, in these cases, taking antihypertensive drugs will not produce the desired antihypertensive effect. 7, overworked Heavy or excessive physical labor will raise blood pressure, long-term overuse of the brain will also lead to further increases in blood pressure, therefore, hypertensive patients should pay attention to rest, to ensure adequate sleep time, not to make the body too fatigued, antihypertensive drugs to play a better effect. 8, excessive mental burden people in a happy, relaxed state, blood pressure will naturally fall, and mental depression, impatience, excessive burden of thought, under the dominant role of the cerebral cortex, the body through the endocrine will produce pressure-raising factors, thus offsetting the role of antihypertensive drugs, so hypertensive patients, should do everything possible to reduce their mental burden, to prevent all adverse stimuli, to maintain a relaxed mood and work and living environment of tranquility.
