Preparation technology of moxifloxacin hydrochloride sodium chloride injection

The present invention belongs to the technical field of preparation technologies of moxifloxacin hydrochloride sodium chloride injections and particularly relates to a preparation technology of a moxifloxacin hydrochloride sodium chloride injection. The preparation technology comprises the following steps: S1, adding sodium hydroxide powder into a sterilized and disinfected stirring tank, then adding 50% by volume of water for injection into the stirring tank, conducting full stirring to fully dissolve the sodium hydroxide powder to form a uniform solution; and S2, raising a temperature in thestirring tank to 90 DEG C, then adding moxifloxacin hydrochloride, and conducting uniform stirring. The preparation technology can accelerate filtration of the solution containing activated carbon powder, thus saves filtration time, improves filtration efficiency, can extract out the solution adsorbed inside the medicinal activated carbon powder and thus improves a generation rate of the solution; and meanwhile, a coarse
