In vitro and in vivo evaluation of gentamicin sulphate-loaded PLGA nanoparticle-based film for the treatment of surgical site infection.

The study focuses on the in vitro and in vivo evaluation of the developed gentamicin sulphate (GS)-loaded poly lactic-co-glycolic acid (PLGA) nanoparticle (PNP)-based pullulan film (PNP-F). Sterilization being an essential pre-requisite for the dosage form was carried out using ethylene oxide. Post-sterilization, PNP-F was evaluated for mechanical properties, percentage drug loading, antimicrobial effectiveness study, test for sterility and in vitro dissolution study using Strat-M® membrane.

Formulation development and in vitro evaluation of gentamicin sulfate-loaded PLGA nanoparticles based film for the treatment of surgical site infection by Box-Behnken design.

Objective: Gentamicin sulfate (GS)-loaded poly lactic-co-glycolic acid (PLGA) polymeric nanoparticles (PNPs) were developed and incorporated in film for the treatment of surgical site infection (SSI).

Method: PNPs were prepared by double emulsification solvent removal technique using ethyl acetate solution containing PLGA and polyvinyl alcohol (PVA) as an emulsifier. The emulsion was re-emulsified using Gum Kondagogu (GKK).
