Design and Characterization of Mucoadhesive Microspheres of Etodolac
Journal Title: International Journal of Pharmaceutical Sciences and Drug Research - Year 2019, Vol 11, Issue 3
Abstract
Mucoadhesive microspheres are drug delivery system intended for targeting a drug to particular region. Etodolac is a Non-steroidal anti-inflammatory drug. The objective of the present work was to develop sustain release of Etodolac loaded mucoadhesive microspheres due to relatively short residence time in the GIT tract before elimination. Mucoadhesive microspheres were prepared by non-aqueous solvent evaporation method using Carbopol 974P, HPMC K100M and HPMC K4M as the polymers. Central composite design was selected for the development of the formulation. Evaluation parameters like particle size, entrapment efficiency, shape and surface morphology, degree of swelling, drug content, in-vitro drug release study and in-vitro drug release study was done. Based on the results obtained from the preliminary formulations three optimized formulations were designed. The percentage mucoadhesion and swelling index of the optimized formulation was found in the range of 66-70 % and 82.50-83.84 % respectively. Optimized formulation releases 90.94% to 92.11% of drug at the end of 10 hours and follows zero order release kinetics.
