summary

My grandmother is a patient with high blood pressure. Because her blood pressure is very high, she needs to take medicine for a long time to reduce her blood pressure. The medicine is divided into three parts. Now her body is not as good as before. What are the side effects of the medicine when we use it? Let me introduce it.

What side effects does the drug have

The first point is that the effect of the first dose of a drug has a beneficial effect. When some patients take a certain drug for the first time, the body does not adapt to the effect of the drug and causes an intolerable strong reaction. Secondary reactions, the adverse consequences caused by the therapeutic effect of drugs, also known as therapeutic contradictions, are not the effects of drugs themselves, but the indirect results of the main effects of drugs. 　　

Second, the side effects of drugs are allergic reactions (allergic reactions), abnormal immune reactions that occur when drugs or drug metabolites in the body stimulate the body as antigens. The occurrence of this kind of reaction has nothing to do with the drug dose or has little to do with it. The main clinical manifestations were skin rash, angioneurotic edema, anaphylactic shock, serum sickness syndrome, asthma and so on.

Third, the side effects of drugs are specific reactions. Due to congenital genetic abnormalities, a small number of patients have adverse reactions unrelated to the pharmacological effects of drugs. The reaction is related to heredity, but not to pharmacology. Most of the reactions are caused by the lack of certain enzymes and the blocked metabolism of drugs in the body.

matters needing attention

In real life, the incidence of adverse reactions in the use of drugs is quite high, especially in the long-term use or large dose use, the situation is more serious, even serious toxicity. Strictly speaking, almost all drugs will cause adverse reactions under certain conditions. However, as long as the rational use of drugs, we can avoid or minimize the harm.
