PHYSICOCHEMICAL METHOD FOR PREPARING CEPHALOSPORIN MICROCAPSULES Russian patent published in 2013 - IPC A61K31/545 A61K9/58 A61K47/32 A61J3/07 B01J13/02

Abstract RU 2500403 C1

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention refers to microcapsulation of cephalosporins related to β-lactam antibiotics. A method for preparing cephalosporin microcapsules is implemented by physicochemical non-solvent addition. That involves using two non-solvents that are carbinol and isopropyl alcohol taken in ratio 1:4. The microcapsule yield makes more than 90%.

EFFECT: method for cephalosporin microcapsules provides accelerating the process for preparing and simplifying the method.
