The optimized formulation of cefixime dispersible tablets were developed using super disintegrants sodium starch glycolate and crospovidone. D-optimal design is used to optimize the formulation of cefixime dispersible tablet to study the effective concentration of independent variables SSG, crospovidone and MCC on responses (dependent variables) i.e. dispersion time, % drug release and % friability. Twelve formulations were prepared and evaluation of pre-compression and post compression parameters of tablets was perfomed. Analysis of variance (ANOVA) probability (p) < 0.05 for responses was found to be significant. A response surface plot is also presented graphically to represent the effect of the independent variables on the dispersion time, % friability and % drug release. Finally, a checkpoint batch is prepared to prove the validity of evolved method. The stability studies of the optimized formulation F13 were carried as per ICH guidelines proved that the optimized formulation was stable even after 2 months.

Aim: The goal of the study was to prepare a superdisintegrant named starch malonate followed by its evaluation for physicochemical properties. Prepared starch malonate was optimized in the preparation of fast dissolving tablets of ibuprofen by using 23 factorial designs. Methods: Compatibility studies like FTIR, TLC and DSC were performed to check any interaction between starch malonate and ibuprofen. Fast dissolving tablets were compressed by direct compression method and subjected to various official tests like hardness, friability, drug content, dissolution etc. Wetting time and water absorption ratio were also performed. At last response surface plot and contour plot was plotted to check the effects of starch malonate, croscarmellose sodium and crospovidone (independent variables) on disintegration time and dissolution efficiency in 5 minutes (dependent variables). Stability studies were also performed to check the stability of prepared fast dissolving tablets of ibuprofen. Results: Results of the studies showed that all the results are within acceptable limits and complying with the criteria of fast dissolving tablets. Drug content was found to be (100±5%), hardness of all tablets were found in between 3.8 -4 kg/cm2, friability was found less than 0.15%. Optimized formulation has showed less wetting time, less disintegration time followed by enhanced drug release. Among all formulation, formulation F2 has shown least disintegration time and enhanced drug release (99.89%) as compared to other formulations. We can conclude that starch malonate can be used as a novel superdisintegrant.

Ulcerative colitis is a chronic idiopathic inflammatory bowel disease that causes chronic inflammation and damage in the gastrointestinal (GI) tract that typically presents in the second or third decade of life with bloody diarrhoea and abdominal cramps. The objective of the present work was to formulate and evaluate of Prednisolone retention enema as a dispersible tablet and it is suspended in suitable vehicle for the treatment of ulcerative colitis. In the present work, an attempt has been made to formulate and evaluate Prednisolone retention enema as a dispersible tablet by using three different methods (direct compression (F1 to F3, wet granulation (F4 and F5) and slugging method (F6)). Prepared dispersible tablets were administered with the help of vehicle for the effective treatment of ulcerative colitis. Dispersible tablets were evaluated for various parameters. In vitro drug release and microbiological evaluation studies were performed to the best formulation in rectal suspension. Then the best formulation was subjected to carry out for stability studies at three different temperatures. Among the six formulations, F6 formulation showed better results. FT-IR study showed that there was no interaction between a drug and excipients. In vitro drug release and microbiological evaluation studies were performed for F6 formulation in rectal suspension. About 99.06 % of the drug was released at 60 min. and also it was found to be microbiologically stable. Results from the stability studies showed that F6 formulation alone and with rectal suspension was stable for a period of 90 days.

In the present study we performed extraction of chia seed mucilage, formulation, and evaluation of buccal mucoadhesive tablet containing extracted mucialge and venlafaxine, an commonly used antidepressant. Tablets were prepared using a formulation mixture of calcium phosphate, talc and magnesium stearate. Tablets were prepared by experimental factorial design software, using central composite design; where the concentration of chia seeds mucilage and that of magnesium stearates were independent variables. Drug release, friability and mucoadhesive strength were studied as dependent variables. Tablets were characterized for post compression profile. The optimized formulation showed the maximum drug release as 99.4% in 6 h, friability of 0.53% and mucoadhesive strength of 20.3 g. These features appear to be adequate for developing a buccal mucoadhesive drug delivery system for venlafaxine.

The aim was to determine the release-modifying effect of carboxymethyl xyloglucan for oral drug delivery. Sustained release matrix tablets of tramadol HCl were prepared by wet granulation method using carboxymethyl xyloglucan as matrix forming polymer. HPMC K100M was used in a small amount to control the burst effect which is most commonly seen with natural hydrophilic polymers. A simplex centroid design with three independent variables and two dependent variables was employed to systematically optimize drug release profile. Carboxymethyl xyloglucan , HPMC K100M , and dicalcium phosphate were taken as independent variables. The dependent variables selected were percent of drug release at 2nd hour and at 8th hour . Response surface plots were developed, and optimum formulations were selected on the basis of desirability. The formulated tablets showed anomalous release mechanism and followed matrix drug release kinetics, resulting in regulated and complete release from the tablets within 8 to 10 hours. The polymer carboxymethyl xyloglucan and HPMC K100M had significant effect on drug release from the tablet (). Polynomial mathematical models, generated for various response variables using multiple regression analysis, were found to be statistically significant (). The statistical models developed for optimization were found to be valid.
