Compound aminopyrine belongs to the antipyretic and analgesic class of anti-inflammatory drugs, and aspirin, ibuprofen and other drugs have similar effects. The main principle of compound aminopyrine is to inhibit the synthesis and release of prostaglandins in the human body, so as to achieve the analgesic effect, but also to achieve the effect of fever, for example, if the patient has a headache caused by a cold and fever and other symptoms, taking 1-2 tablets of compound aminopyrine can not only alleviate the symptoms of the patient’s headache, but also reduce the patient’s body temperature. However, compound aminopyrine is a non-selective antipyretic and analgesic anti-inflammatory drug, which may lead to the development of peptic ulcer and other symptoms, resulting in epigastric pain, black stools and so on.
