The present study involves in the formulation and evaluation of sustained release tablets of Voriconazole (250mg). The objective of the present study was to formulate Voriconazole sustained release tablets by wet granulation method by using natural (Xanthan gum, Karaya gum) and semi synthetic polymers (HPMC K100M). Lactose was used as diluting agent, Magnesium stearate was used as a lubricant and Talc was used as a glident. These sustained release tablets can release the drug up to 12 hours in predetermined rate. The formulated powder blend was evaluated for bulk density, tapped density, compressibility index and angle of repose. The formulated tablets were evaluated for physical characteristics of sustained release tablets such as thickness, hardness, friability, weight variation and drug content. The results of the formulations found to be within the limits specified in official books. The tablets were evaluated for In-vitro drug release studies by using USP type I dissolution test apparatus. The dissolution test was performed in 0.1 N HCL for 2 hr and phosphate buffer pH 6.8 for 10hrs. The in-vitro cumulative drug release profile of all formulations F1-F10 at 12 hours showed 84.25% to 99.82% drug release, respectively. From the data it was clear that by increasing the amount of polymer in the formulation the amount of drug release was decreased. Hence, Formulation F9 was the most promising formulation as it gives satisfactory release (99.82%) for 12 hours and F9 found to be the best formulation.DOI: http://dx.doi.org/10.3329/icpj.v2i10.16410 International Current Pharmaceutical Journal, September 2013, 2(10): 165-169

This work aims at the design of a sustained release formulation of glimepiride which is currently available in the treatment of type 2 diabetes mellitus and to investigate the effect of polymers on the release profile of glimepiride. Glimepiride sustained release tablets were prepared by direct compression method using different ratios of various release retarding polymers such as carbopol, ethyl cellulose, methocel K4 MCR, methocel K15 MCR, methocel K100 MCR and xanthum gum. These formulations were also compared with glimepiride immediate release tablets. The prepared tablets were subjected to various physical parameter tests including weight variation, friability, hardness, thickness, diameter, etc. In vitro dissolution studies of the formulations were done at pH 6.8 in phosphate buffer using USP apparatus 2 (paddle method) at 50 rpm. The percent releases of all the formulations (30) were 73.11%- 98.76% after 8 hours. The release pattern followed zero order kinetics and the release of the drug was hindered by the polymers used in the study. On the other hand, 100% drug was released within 1 hour from the immediate release tablet of glimepiride. The study reveals that the polymers used have the capacity to retard the release of the drug from the sustained release tablets and the more is the amount of the polymer in the formulation the less is the release of drug showing more retardation of drug release.Bangladesh Pharmaceutical Journal 18(2): 157-162, 2015

INTRODUCTION Domperidone is a unique compound with gastro kinetic and antiemetic effects. It is used in the management of disorder by impaired motility like gastroesophageal reflux (in some instances), gastroparesis, dyspepsia, heartburn, epigastric pain, nausea, vomiting, and colonic inertia. The sustained release system is a widely accepted approach for slow drug release over an extended period to address the challenges of conventional oral delivery, including dosing frequency, drug safety, and efficacy. The study aims to formulate a domperidone sustained release tablet and compare the dissolution rate with the marketed formulations. MATERIAL AND METHODS Sustained release matrix tablets of domperidone were prepared by wet granulation method using different polymers such as HPMC K4M, ethyl cellulose, Gum acacia. Pre-compression studies like angle of repose, bulk density, tapped density, Carr's index, and Hausner’s ratio, and post-compression studies like weight variation, thickness, hardness, friability, drug content, and in-vitro drug release were evaluated.   RESULTS The release profile of domperidone sustained-release tablets was studied spectrophotometrically. The in-vitro dissolution study suggests the minimum %-cumulative drug release with 98.33% in F5. The %-cumulative drug release was maximum in F3 with 99.69%. The in-vitro drug release of all the formulations was non-significant compared to the marketed formulation (p<0.05), exhibiting the sustained-release property by all the formulations. CONCLUSION The pre-compression study concludes the better flow property of the granules of different formulations. The sustained release domperidone tablets were prepared successfully by the wet granulation method. The post-compression parameters of different formulations were within the acceptable range.

Diospyros melonoxylon Roxb is a small tree with rather slender stem and smooth grey bark belonging to family Ebenaceae found widely in Chhattisgarh. The present investigation reports the isolation of mucilage from Diospyros melonoxylon seeds as per AOAC guideline and evaluating it as mucoadhesive agent. Physiochemical characteristics of mucilage, such as appearance, solubility, swelling index, microbial count, loss on drying, viscosity, hydration capacity, flow property, hausner ratio and pH were studied. The mucilage was evaluated for its mucoadhesive properties in compressed tablet, using Losartan Potassium as model drug. Granules were prepared by wet granulation process using polyvinylpirroli-done as binding agent. Mucilage was used in four different concentrations i.e. 20, 40 and 60 % w/w. The prepared granules were evaluated for micrometrics property. The tablet were prepared and evaluated for weight variation, thickness diameter, hardness, percent friability, in vitro dissolution and degree of swelling. The property of bioadhesive strength of isolated mucilage was compared with Guar Gum and HPMC E5LV, which was used as standard mucoadhesive agent concentration. Bioadhesive strength of the tablet was measured on the modified physical balance. The tablets had good physiochemical properties, and drug release was retarded as concentration of mucilage was increased. The force of adhesion was obtained 0.2063N, 0.3837N, 0.5175N, 0.8679N and 0.3983N respectively for F1, F2, F3, F4 and F5. Formulations were subjected for study of effect of intensity of agitation at different rpm (50 and 150) and electrolyte (NaCl and CaCl2), and formulation showed relative effect on release of drug from formulation. All the formulations were subjected to stability studies for three months all formulation showed stability with respect to release pattern.
