| Summary: | Intramuscular injection and intravenous injection are important routes of drug administration, which not only have a fast absorption rate, but also avoid the first pass effect of the drug. In 2009, Yangtze Pharmaceutical Group redeveloped Dezocine(13-Amino-5,6,7,8,9,10,11,12-octahydro-5-methyl-5,11-methanobenzocyclodecen-3-ol), molecular formula: C16H23NO, in the form of njection. Quickly, Dezocine injection becomes the first choice for perioperative pain management in China and accounts for 45 % of the analgesic market. This study mainly used animal pain models to study the analgesic effects of Dezocine injection. The results indicated that Dezocine produced potent analgesic effect in the hot plate and writhing tests.
