In the clinic, many hypertensive patients hold the view that it is appropriate to start with cheap antihypertensive drugs, and then choose expensive drugs when the cheap ones do not work. In fact, this view is incorrect. Now the emphasis on lowering blood pressure will be balanced and lasting control in the target range, especially in the morning blood pressure to control, blood pressure fluctuations should not be too large. Inexpensive antihypertensive drugs such as nifedipine tablets, nifedipine tablets, Beijing antihypertensive 0, Zhenju antihypertensive capsules are short-acting drugs, fast-acting, short duration of drug maintenance. If blood pressure is lowered too quickly, it will lead to insufficient blood supply to the heart, brain and other organs; the short maintenance time of the drug will make blood pressure fluctuate greatly, and the fluctuation of blood pressure will aggravate the damage of vascular endothelium, leading to ischemia and bleeding events; these drugs need to be used 2~3 times a day, so it is easy to forget to take the drug, and forgetting to take the drug will make blood pressure rebound higher. Therefore, it is advisable to choose antihypertensive drugs that have a mild effect and can be taken once to maintain a 24-hour antihypertensive effect. Although the price is expensive, the benefit is also greater. Of course, if the economic conditions do not allow, choose cheap antihypertensive drugs is also possible. It is better to take the medicine than not to take the medicine.
