Abstract
Tuberculosis (TB) is the leading cause of infectious diseases affecting the 2 billion people worldwide. To improve the current method of treatment a synthetic polymeric anti-TB nanodrug delivery system was attempted. A series of PLGA polymers with different molar feed ratios i.e., 90/10, 75/25, 50/50 were synthesized by direct melt polycondensation method. The PLGA nanoparticles and the drug (Rifampicin (RIF)) encapsulation were prepared by double emulsion-solvent evaporation technique. The in vitro release profile of the RIF loaded PLGA NPs showed an initial burst followed by sustained release. The nanoparticles were remarkably advantageous in terms of high drug encapsulation efficiency, low polymer consumption and better sustained release profile.
