Microsponges being the polymeric drug delivery systems consist of porous microspheres that can entrap a wide range of active ingredients. Boswellic acid is a pentacyclic triterpenoid having anti-inflammatory, anti-hypertensive, anti-cancer activities. The aim of the study was to develop, characterize and formulate microsponge delivery for topical application. The Microsponges were prepared by quasi emulsion solvent diffusion method using QbD approach. Drug excipient compatibility study was carried out by FT-IR, DSC and XRD. The prepared Microsponges were further evaluated for its physicochemical properties by scanning electron microscopy (SEM), photomicroscopy, transmission electron microscopy (TEM), particle size, zeta potential, and porosity analysis. The optimized Microsponges were incorporated into gel base formulation and evaluated for in-vitro drug release, dissolution studies and ex-vivo permeability studies. Further, microsponge formulations, subjected for animal studies for skin irritation test and clinical efficacy. The present study confirmed the formation of Microsponges of Boswellic acid. It also proves the sustained release of drug through microsponge formation.
