Description
technical field [0001] The invention is a freeze-dried powder injection mainly composed of pyrithione hydrochloride and a preparation method thereof. Background technique [0002] Pyritinol hydrochloride is a derivative of vitamin B6. It was developed and launched in Japan in 1962. It was synthesized and published in my country in 1972, and then the aseptic subpackaged preparation, pyrithione hydrochloride for injection, was launched on the market. Pyritinol hydrochloride for injection can improve brain function, promote the metabolism of glucose and amino acids in the brain, increase cerebral blood flow, promote brain cell nutrient metabolism, and improve cerebral hypoxia. It has been clinically confirmed by many hospitals: the drug has a good curative effect on traumatic brain injury and cerebral coma; it is particularly effective in promoting the recovery of consciousness; it has no obvious toxic and side effects and is safe to use. At the same time, the drug is also u...
