Problems solved by technology

[0003] At present, methanol, ethanol, ethyl acetate, tetrahydrofuran, isopropanol, acetonitrile and other solvents are usually used in the preparation process of existing caspofungin acetate, and the purification is difficult, so the solvent in the prepared caspofungin acetate finished product The content is usually difficult to meet the relevant regulations on solvent residues. At the same time, the resulting product has poor stability and needs to be stored at low temperature, which increases the cost of transportation and storage of the finished product of caspofungin acetate

Abstract

The invention discloses a device for preparing caspofungin acetate for injection, comprising a drying tower. The drying tower comprises a bottom plate, a side plate and a top plate. The top plate is provided with a plurality of atomizing nozzles. The atomizing nozzles pass through the top plate toward the bottom plate. The tops of the atomizing nozzles are connected through a guide pipe to a reservoir for storing a caspofungin acetate solution. The side plate of the drying tower is provided with an air nozzle. The air nozzle is connected to a helium storage tank through an air guiding pipe. The device can effectively improve the purity of the prepared caspofungin acetate for injection, thereby avoiding the degradation of caspofungin acetate and improving the stability of the product.

Description

technical field [0001] The invention relates to the field of pharmaceutical manufacturing, in particular to a device for preparing caspofungin acetate for injection. Background technique [0002] Caspofungin acetate for injection can be used for empiric treatment of neutropenia, suspicious fungal infection in patients with fever, and invasive aspergillosis that is ineffective or intolerable to other treatments. Caspofungin is effective against Aspergillus (including Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, A. Candida, Candida gillimont, Candida kactii, Candida krusei, Candida lipolytica, Candida portuguese, Candida parapsilosis, Candida plicata, and Tropicale) with in vitro activity, caspofen acetate Net can inhibit the synthesis of β(1,3)-D-glucan in the cell wall of many filamentous fungi and yeasts, thereby inhibiting the reproduction of pathogenic bacteria, and there is no P(1,3)-D-glucan in mammalian cells Polysaccharides, so the side effects on t...
