Preparation method of ciprofloxacin hydrochloride

The invention discloses a preparation method of ciprofloxacin hydrochloride. The existing synthesis method generally uses isoamyl alcohol and the like as solvent, thus having the problems of strong smell, difficult biodegradation and higher environmental pollution. If the solvent such as the isoamyl alcohol and the like is used, more alkali insoluble substances and acidic insoluble substances are generated in recovery after the reaction, so that the insoluble substances are needed to be treated by purification through the steps such as alkali-dissolving heat-filtering call-back throw filter, acidic-dissolving heat-filtering call-back throw filter, salifying decoloration heat-filtering and the like, the process route is longer, and the product yield is lower. The preparation method of the ciprofloxacin hydrochloride selects the proper solvent as reaction medium, firstly leads cyclopropane carboxylic acid and piperazine to have piperazine reduction reaction and then leads the reaction product to be salified together with hydrochloric acid. In the reaction process, less alkali insoluble substances and acidic insoluble substances are generated in the reaction process, and the ciprofloxacin hydrochloride can be obtained by salifying decoloration heat-filtering, separation by crystallization, throw filter, rinsing and drying after being directly cooled and leached, so that the time for occupying equipment and the time of working procedures are shortened, and the production efficiency of a workshop is improved.

Hydrochloric acid ciprofloxacin lipidosome preparation and preparation method thereof

The invention discloses a preparation method of a hydrochloric acid ciprofloxacin lipidosome preparation. The preparation method includes the steps that one part of hydrochloric acid ciprofloxacin is weighed, a phosphate buffer solution is added and stirred, and a hydrochloric acid ciprofloxacin solution is obtained; 2, blank liposome is prepared, wherein 10-50 parts of soya bean lecithin and 5-40 parts of cholesterol are weighed and mixed, chloroform is added and stirred for being dissolved, decompression is conducted for removing solvent, and a blank phospholipid membrane is prepared; 3, the membrane is dissolved through a small amount of chloroform, the hydrochloric acid ciprofloxacin solution obtained in step 1 and the phosphate buffer solution are taken for being added into an acetate solution, ultrasound treatment is conducted for 10-30 minutes through a bath type ultrasonic instrument at the temperature of 45-60 DEG C, a stable solution is formed, the obtained lipidosome solution is filtered twice through a microfiltration membrane, granulation is conducted, and the hydrochloric acid ciprofloxacin lipidosome preparation is obtained. The lipidosome produced through the ultrasonic instrument has the advantages that the particle size is small, particle size distribution is narrower, and the lipidosome has good preparation nature and target ability, can improve the curative effect, has a long-term effect, can reduce drug toxicity and can improve the drug stability.
