Abstract

The purpose of the present work was to develop optimized novel enteric microcapsules containing diclofenac sodium, a non steroidal anti inflammatory drug (NSAID) used for rheumatoid arthritis, for improved delivery and to diminish its adverse effect after oral administration. The microcapsule was prepared by using different polymers and the enteric coating was provided by using an innovative technique combining wet granulation method and thermal change method. This work also investigated different levels of enteric polymers like cellulose acetate phthalate (CAP) (X1) and ethyl cellulose (EC) (X2) and the stirring speed during coating ethyl cellulose (X3), by using 23 full factorial design. The dependent variables assessed were % yield (Y1), Q8 (% drug released after 8 hour) (Y2), n (Diffusion coefficient) (Y3), DEE (Drug entrapment efficiency) (Y4). The main effect and interaction terms were quantitatively evaluated using a mathematical model. The prepared microcapsules were evaluated for percentage drug dissolved, scanning electron microscopy, drug excipient interaction, angle of repose, particle size. Mean dissolution time (MDT) was used to compare dissolution patterns obtained. The results showed that X1 and X2 significantly affected the release properties.

Abstract

The main objective of this study was to prepare Quick Dispersible Tablets of drug Sumatriptan Succinate, which can rapidly disintegrate in the saliva using three different Superdisintegrants that is, Sodium Starch Glycolate, Crospovidone, and Croscarmallose Sodium with Taste Masking Polymer Beta-Cyclodextrin and Aspartame as a Sweetener. The taste masking of the drug was done by mixing it with the polymer beta-cyclodextrin using Solvent Evaporation method and then mixing optimized quantity of aspartame to it. The Quick Dispersible tablets were prepared by Direct Compression Technique using taste masked drug and other formulation excipients. The effect of various Superdisintegrants in three different concentrations has been studied. The prepared tablets were evaluated for wetting time, In-vitro Disintegration time, strength, and in-vitro Dissolution time. As per the results obtained, it was found that the formulation batch no. 4 was found to be the best formulation, as the data?s obtained by it was found to be in the required range of mouth dissolving tablets.
