It's believed that when many people were sick and feverish when they were young, doctors would always prescribe one or two tablets of analgin. The effect of reducing fever is quite remarkable. But in the past two years, we seldom see the figure of analgin in drugstores. What's the matter? Why is analgin banned?
In 1920, the German invented analgin, used for antipyretic and analgesic. Because the antipyretic effect is obvious, it is widely used and reaches the peak of blood concentration within 2 hours. However, with the long time of clinical application, it has been found that analgin has serious adverse reactions, which has attracted the attention of many countries.
There are two reasons for the delisting of a drug. There are serious adverse reactions, or there are new drugs of the same kind, with better efficacy and less side effects. Both of these reasons are possessed. It's embarrassed not to go out of the market. In 1974, Sweden took the lead in revoking its marketing license. It was followed by the U.S. withdrawal of its listing license in 1977. Later, many countries, such as the European Union, Japan, Iran, Australia, India and so on, banned the drug. Because of China's special national conditions, analgin is cheap. In the 1970s and 1980s, it helped many patients in many places. However, with the development of China 's economy and the improvement of people' s living standards, many people pay more attention to health, and An Naijin is inevitably eliminated.
The adverse reactions of analgin are not so common and light as many drugs, but rather serious, and may cause death. Side effects are as follows:
1.1% neutropenia can occur in the blood system analgin group, which can reduce the immune capacity of patients, and also cause aplastic anemia and thrombocytopenic purpura.
Anaphylaxis can cause urticaria, exudative erythema, severe exfoliative dermatitis, epidermolysis, anaphylactic shock.
Urinary system reaction can lead to urinary incontinence, long-term use may cause renal failure.
At present, it is not generally used as the first choice medicine, only in the case of acute high fever, severe illness, and no other effective antipyretics. If you find that you take this medicine for a long time to relieve fever and pain, stop taking it immediately.
