Popis: | This study focuses on the development of the polymeric composition of linezolid based on biodegradable polymeric carriers. Polymeric compositions within linezolid were prepared by the simple emulsification method using a series of polymers such as PLGA 50/50, PLGA 75/25, PLGA-COOH 50/50, Eudragit RL, and Eudragit RS. The best characteristics were achieved by a composition obtained by using the polymer PLGA 50/50. The content of linezolid in the composition was 9.4 ± 0.47%, the inclusion efficiency was 50 ± 2.50%, and the particle size was 275 ± 13 nm. A study of antimicrobial activity of the polymer composition was performed by standard methods using cambric tests on Myulton-Hiller medium at a concentration of active ingredient 500 μg/mL. Experimental results demonstrated that the polymeric composition exhibited higher specific activity against Staphylococcus aureus than the substance. |
