DESIGN AND EVALUATION OF MODIFIED CHITOSAN BASED IN SITU GEL FOR OCULAR DRUG DELIVERY
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2017, Vol 9, Issue 10
Abstract
Objective: The object of the present study was to formulate and evaluate in-situ gel of modified chitosan by using temperature triggered method to improve bioavailability.Methods: Modified chitosan-based moxifloxacin HCl was prepared by cold method. polaxomer 407 adding in distilled water and this solution kept in the refrigerator. Modified chitosan and moxifloxacin HCl was dissolved separately in distilled water and added to the polymeric solution with continuous stirring until thoroughly mixed. Prepared formulation was evaluated for drug content, gelling capacity, rheological study, in vitro drug release behavior, measurement of phase change temperature, antibacterial study, release kinetics, statistical analysis.Results: The prepared formulations were evaluated for their, drug content, gelation temperature, in vitro drug release studies, rheological study and release kinetics. All batches of in situ formulations had satisfactory pH ranging from 6.2±0.2, drug content between 98.8±0.2 showing uniform distribution of drug. As the concentration of each polymeric component was increased, there was a decrease in phase change temperature. The in vitro drug release decreased with increase in polymeric concentrations. The antibacterial efficiency of the selected formulation against staphylococcus aureus confirmed that designed formulation has prolonged effect and retained its properties against bacterial infection.Conclusion: The prepared in situ gelling formulation had the appropriate combination of polaxomer 407 and modified chitosan were suitable satisfactorily sustained the drug release from moxifloxacin HCl in situ gel. The prepared formulation of moxifloxacin HCl appears to be promising drug delivery for bacterial infectious disease.
