Problems solved by technology

[0006] Following the disclosure of a method for preparing naloxone and the obtained naloxone product in Chinese patent CN103695497B, the inventor is not limited by the development trend of the prior art, and does not give up paying attention to naloxone hydrochloride injection , studies have found that solid preparations such as naloxone hydrochloride powder injections are easily combined and used in excess, and will be used by criminals, so there is still a need to develop new naloxone hydrochloride injections; moreover, the inventor is not afraid of existing Existing technology has always been unable to solve the problem of poor heat resistance of naloxone hydrochloride injection, and faced up to the difficulties. After arduous research, a new prescription of naloxone hydrochloride injection was unexpectedly developed, which enhanced its heat resistance Resistant, making it suitable for high temperature sterilization and long-term storage, can be sterilized by overkill method with F0 value up to 15
