Development of Lipomer Nanoparticles for the Enhancement of Drug Release, Anti-microbial Activity and Bioavailability of Delafloxacin
Delafloxacin (DFL) is a novel potent and broad-spectrum fluoroquinolone group of antibiotics effective against both Gram-positive and negative aerobic and anaerobic bacteria. In this study, DFL-loaded stearic acid (lipid) chitosan (polymer) hybrid nanoparticles (L-P-NPs) have been developed by single-emulsion-solvent evaporation technique. The mean particle size and polydispersity index (PDI) of optimized DFL-loaded L-P-NPs (F1-F3) were measured in the range of 299-368 nm and 0.215-0.269, respectively. The drug encapsulation efficiency (EE%) and loading capacity (LC%) of DFL-loaded L-P-NPs (F1-F3) were measured in the range of 64.9-80.4% and 1.7-3.8%, respectively. A sustained release of DFL was observed from optimized DFL-loaded L-P-NPs (F3). Minimum inhibitory concentration (MIC) values of the DFL-loaded L-P-NPs (F3) appeared typically to be four-fold lower than those of delafloxacin in the case of Gram-positive strains and was 2-4-fold more potent than those of delafloxacin against Gram-negative strains. The pharmacokinetic study in rats confirmed that the bioavailability (both rate and extent of absorption) of DFL-loaded L-P-NPs was significantly higher (2.3-fold) than the delafloxacin normal suspension. These results concluded that the newly optimized DFL-loaded L-P-NPs were more potent against both Gram-positive and negative strains of bacteria and highly bioavailable in comparison to delafloxacin normal suspension.
