Preparation of Ceftazidime anhydrous: it is prepared by reaction of cefotaxime pyridine. Firstly, cefotaxime pyridine reacts with trimethyl silicon chloride and phosphorus pentachloride to get amorphous solid. Dealing with the solid by acetonitrile containing hydrochloric acid. Secondly, the compound reacts with (z)-2-(2-tert-butoxy carbonyl C-2-oxygen Nokia amino)-2-(2-triphenylmethyl-amino thiazol-4-yl) acetyl chloride with solvent dichloromethane. Thirdly, add mixture of dimethylformamide, formic acid and hydrochloric acid after washing and steaming. At last, add acetone or methanol after removing sediment. Compound is dissolved in water and the precipitate is the Ceftazidime.

Uses of Ceftazidime anhydrous: it is mainly used as clinical medicine for respiratory system, urinary system, soft tissue infections caused by susceptible. Ceftazidime anhydrous is used as third-generation broad-spectrum cephalosporin.

When you are using Ceftazidime anhydrous, please be cautious about it. As a chemical, it is irritating to eyes, respiratory system and skin. It is harmful by inhalation, in contact with skin and if swallowed. During using it, wear suitable protective clothing. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
