Problems solved by technology

However, in the two-step preparation, the concentrated preparation is not easy to dissolve, and two preparation tanks are required, the consumption of equipment cleaning and cleaning control is large, and the risk of contamination is high
Activated carbon has an adsorption effect on moxifloxacin, and excessive feeding is required to meet the quality requirements. Moreover, the production and quality standards of activated carbon are uneven, and there is a risk of promoting the degradation of related substances. At the same time, it is very easy to cause activated carbon to fly when weighing and feeding activated carbon. polluted clean area
The recovery and treatment of activated carbon after use will also put pressure on environmental protection

Abstract

The invention relates to the technical field of pharmaceutical preparations, and particularly discloses a moxifloxacin hydrochloride sodium chloride injection and a preparation method thereof. The preparation method comprises the following steps: adding moxifloxacin hydrochloride, sodium chloride and a pH regulator into water for injection, stirring for dissolving, filtering through 3 or 4 groupsof polyether sulfone filter elements with sequentially reduced pore diameters, performing filling, and sterilizing to obtain the moxifloxacin hydrochloride sodium chloride injection. The injection provided by the invention is stable in batch content, low in related substance content, high in effectiveness and safety and good in stability.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a moxifloxacin hydrochloride sodium chloride injection and a preparation method thereof. Background technique [0002] Moxifloxacin hydrochloride is a broad-spectrum and 8-methoxyfluoroquinolone antibacterial drug with antibacterial activity. Clinically, it is mainly used for the treatment of acute bacterial sinusitis, acute exacerbation of chronic bronchitis, community-acquired pneumonia, complicated intra-abdominal infection, and skin and skin tissue infection. Clinically, Moxifloxacin Hydrochloride Sodium Chloride Injection for intravenous infusion is a 250ml large-volume injection; it is used to rescue critically ill patients, and has a quick onset and remarkable curative effect. [0003] The existing Moxifloxacin Hydrochloride Sodium Chloride Injection is packaged in a semi-open glass bottle, and the preparation method is divided into two steps of concen...
