Some people say that the most expensive antihypertensive drug is a good drug, while others say that the cheapest drug is a good drug, but in fact, this is not accurate enough. Medical practice proves that only the most suitable is the best antihypertensive drug. Hypertension antihypertensive treatment has two purposes, one is to reduce the mortality rate of patients, the second is to reduce a variety of complications caused by high blood pressure, including myocardial infarction, angina pectoris, heart failure, stroke, kidney failure, etc.. Drugs that can achieve these two purposes should be said to be effective drugs. However, since different patients have different conditions, the same criteria cannot be used to determine whether a particular drug is appropriate. This includes age, gender, weight, dietary structure, concomitant diseases, family history, whether or not to smoke, etc. It also includes ethnicity, literacy, affordability and awareness of the disease. Generally speaking, the criteria for judging a good medicine are: 1. safety: it means less toxic side effects and cannot cause another kind of lesion because of treating one kind of lesion, which is the first. 2.Effective: It means that the blood pressure can be controlled effectively after taking the medicine, so that the blood pressure can reach the standard. 3, stable: refers to the blood pressure after taking the drug does not because the drug action time is short, after the effect of the drug or forget to take the drug, thus causing excessive up and down fluctuations in blood pressure. 4, lasting: refers to the relatively long duration of action of the drug, basically can cover 24 hours. 5, convenient: refers to the operation is simple, easy for patients to take long-term. The antihypertensive drugs currently listed in China have been reviewed and approved by the national authorities and are qualified drugs, but there are many types, many manufacturers, many names of one drug, and similar drug names are common. Therefore, patients need to be prescribed by a specially trained hypertensive doctor to ensure that they get the most suitable antihypertensive treatment for themselves.
