Formulation, optimization and in vitro evaluation of sustained release oral hydrogels of diacerein to treat arthritis
The current study is aimed to formulate pH responsive polymeric hydrogels. Potassium per sulphate and Methylene bis acrylamide were employed as initiator and cross linker respectively. To determine the effect of substrate on degree of cross linking different ratios of the acrylic acid (AA), potassium per sulphate (KPS) and methylenebisacrylamide (MBA) were used. Swelling experiments were conducted in both basic and acidic media. Phosphate buffer of pH 7.4 and 0.1N HCl solution were used for swelling experiment of hydrogels. The hydrogels were more responsive towards basic medium as compared to acidic environment. Formulations were also evaluated for In vitro evaluation. Diacerein was selected model drug for hydrogel. Release pattern of the diacerein was studied both in acidic (0.1N HCl solution) and basic medium. Percentage drug release from M3 formulation showed as cross linker concentration increase (0.03%) drug release decrease Hydrogel samples were characterized by FTIR to confirm the functional groups of the hydrogels and their components and scanning electron spectroscopy (SEM) was performed to characterize the structure or morphology of the hydrogels. Finally, the dissolution studies were performed to evaluate the sustain release property of the hydrogel samples. Results show that all formulations of hydrogels are pH-sensitive and follow zero-order kinetics for drug release. Hence, optimized nexus (M3) serves as excellent carrier for target drug delivery.
