Abstract

The present invention relates to a stable naloxone powder injection. The naloxone powder injection described by said invention is formed from naloxone or its physiologically-aceptable salt and pharmacologically-allowable injection auxiliary material. It can be extensively used for curing various diseases of acute alcoholism, cerebrovascular accident, ischemic encephalopathy, coma, craniocerebral injury and imminent serious diseases, and can be used for removing respiratory inhibition and inducing awavening after combined anesthesia and operation.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a stable medicine in a special dosage form for analgesia and antagonism of respiratory depression medicine. Background technique [0002] Naloxone was synthesized in 1960 as a derivative of oxy(di)hydromorphone. Naloxone is a pure opioid receptor antagonist clinically used in the treatment of overdose and poisoning of narcotic analgesics. In addition to being used to antagonize the respiratory depression caused by morphine drugs, clinical workers have also tried stress diseases such as overdose of non-narcotic drugs (ethanol, diazepam), shock, cerebral infarction, and neonatal asphyxia syndrome, and achieved relatively good results. The good therapeutic effect has aroused great interest of doctors at home and abroad. Naloxone has an antagonistic effect on the analgesia and respiratory depression induced by narcotic analgesics such as heroin, morphine, codeine, and pethidine. It...
