Polysaccharide-Based Controlled Release Systems for Antipsychotic Therapeutics Delivery

Abstract

Researches in pharmaceutical fields are now focusing on biopolymer-based drug delivery systems for treatment of mild  to severe diseases.  Amongst  all biopolymers, pectin is one of the frequently available and eco-friendly bio-polymer extracted from different fruit peels and abundantly available in nature. This study focuses to extract the pectin from two different fruits using different methods namely hot water-based extraction and cold maceration, involving two different fruit peels. Post extraction and isolation of polymer, study was performed for characterization of pectin powder by particle shape, particle size distribution, surface area angle of repose, flowability and tapped density. The obtained pectin was used for anti-psychotic drug delivery when incorporated into microspheres by solvent evaporation method. It’s surface morphology and release kinetics was analyzed using in vitro methods and in vivo models and kinetics of drug release (goodness of fit) was assessed. The result revealed that the pectin extracted from mango peel using soxhlation method showed good flow rate, minimum particle size and shape distribution, porosity etc. Moreover, it showed the better drug release data in both invitro and in-vivo analysis. The study concludes that in future the natural biopolymer like pectin stands as a potential candidate for formulation of drug release system for efficient delivery of drug.
