Among the different approaches to achieve protein delivery, the use of polymers, specifically biodegraded, holds great promise. In this work, a new microsphere delivery system composed of alginate microcores surrounded by a biodegradable poly-DL-lactide-poly(ethylene glycol (PELA) was designed to improve the loading efficiency and stability of proteins. Alginate was solidified by calcium (MS-1)...

Chitosan microsphere has important application in controlled release of protein and peptide drug, because it shows excellent mucoadhesive and permeation enhancing effect across the biological surfaces. In the conventional preparation methods of chitosan microsphere, the W/O emulsion was usually prepared by mechanical stirring method, and then the droplets were solidified by glutaraldehyde. Ther...

The present investigation was to prepare and evaluate bioadhesive vaginal gel containing clotrimazole loaded microspheres a novel delivery system for vaginal use. Bioadhesive gel was prepared by incorporating drug loaded microspheres using bioadhesive polymer carbopol 934. Microspheres were prepared by spray drying technique using Eudragit RS-100 and RL-100 polymers with different drug/polymer ...

Objective: Sustained release systems have the potential to enhance therapeutic responses in long-term management of psychiatric disorders. In present study, cross-linked microspheres antipsychotic drug Trifluoperazine (TFP) were prepared using biodegradable polymer-chitosan and various vitro evaluations performed on microspheres. Methods: The spray drying technique was used prepare TFP-loaded c...
