The aim of this study was to design orally disintegrating tablet (ODT) of Lamotrigine. It is an Antiepileptic drug which is widely used in epilepsy. It is also used in simple and complex partial seizures and secondary generalized tonic-clonic seizures. It is poorly water soluble drug (0.46 mg/ml). Thus, an attempt was made to enhance the water solubility by complexation with β-cyclodextrin (1:1 molar ratios). The orally disintegrating tablet of lamotrigine was prepared by direct compression method using different concentration of superdisintegrants such as Sodium starch glycollate, croscarmellose sodium by sublimating agent such as camphor. The formulations were evaluated for weight variation, hardness, friability, drug content, wetting time, in vitro disintegration time and in vitro dissolution studies. The prepared tablets were characterized by Fourier transform infrared spectroscopy and differential scanning calorimetry. The disintegration time for the complexed tablets prepared by different concentration of superdisintegrants was found to be in range of 32.54 ± 0.50 to 55.12 ± 0.57 sec and wetting time of the formulations was found to be in range of 28.47 ± 0.67 to 52.19 ± 0.72 sec. All the formulation showed almost 100 percent of drug release within 15 min. Among all the formulation F6 and F7 prepared with 18% croscarmellose sodium and camphor shows faster drug release, respectively 10 min, F6 gives good result for disintegration time, drug release, wetting time and friability. Further formulations were subjected to stability testing for 30 days at temperature of 40 ± 5 ºC/75 ± 5 %RH. Tablets showed no appreciable changes with respect to physical appearance, drug content, disintegration time and dissolution profiles. Results were statistically analyzed by one-way ANOVA at a p < 0.05. It was found that, the data at any point of time are significant at p < 0.05.

Twenty three different tablet formulations of alprazolam were prepared using Polymer like hydroxypropylmethyl cellulose (HPMC K4M, HPMC K15M and HPMC K100M) in the concentration of 5 – 50 % of total weight of tablets and combination of HPMC K15M and HPMC K100M with ethyl cellulose (EC) was formulated by using wet granulation method. Drug formulation containing 1.0 mg, 1.5 mg, 5 mg, 10 mg and 15 mg alprazolam per tablet maintaining constant HPMC K15M concentration was also developed.The in-vitro dissolution studies of the formulated and marketed product in USP type II apparatus showed that the drug release is dependent upon the drug: polymer ratio; also molecular weight of the polymer and solubility of loaded drug. With increasing concentration and molecular weight of polymer, drug release was found to be decreased. When formulating the tablets the method used whether direct compression or wet granulations also affect the release of the drug from matrix. Wet granulation method by using 40 % HPMC K15M in combination with 5 % EC was found to be most suitable controlled release alprazolam tablet as drug release was found to be appreciable in this formulation. When loading dose of alprazolam was increased, drug release was found to be tremendously decreased because of the poor solubility of alprazolam in water. When one-way ANOVA was applied for various formulated and marketed tablets it was found that there is no significant difference (p > 0.05) in drug release rate among formulation similarly model independent methods was also applied such as similarity and dissimilarity factor and found that there is no significant difference between these formulations.DOI: http://dx.doi.org/10.3126/jmmihs.v1i1.9896 Journal of Manmohan Memorial Institute of Health Sciences Vol.1(1) 2011; 8-23

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.

Current study is to develop the colon targeted matrix tablet using the natural polysaccharide sterculia gum as carrier and model drug ciprofloxacin HCl. The matrix tablets were prepared by wet granulation technology using the various proportions of sterculia gum with carbopol 934 P, sterculia gum and ethyl cellulose polymer blends. Granules of all formulations were evaluated for rheological, post compressional properties and in vitro dissolution study in different pH buffers of pH 1.2 , pH 7.4 , pH 6.8 (saline phosphate buffer) without and with 4% rat cecal content in order to mimic GIT condition . Formulation SGC2 to SGC4 and SGE7 to SGE9 has released 13.6% to 38.9% in the initial 5h and released more amount of drug in stomach and small intestine than colon. Formulation SGC5 containing 45% of sterculia gum and 25% carbopol 934 p and Formulation SGE10 containing 45% of sterculia gum and 25% ethyl cellulose has released minimum 10.91 % to 13.04 % in the initial 5h and sustained the drug release up to 24 h and at the end of study released 75% to 79.99%. Formulations with 4% rat cecal content at the end of 24 h study drug released is 90.44% to 95.33% indicating higher amount of drug release is due to enzymatic break down of sterculia gum in the matrix tablet. Hence the above results conclude that the formulation SGC5 and SGE10 are potential in targeting the drug to colon to treat irritable bowel disease.DOI: http://dx.doi.org/10.3329/icpj.v1i11.12064 International Current Pharmaceutical Journal 2012, 1(11): 376-383

The purpose of this research was to develop a matrix-type transdermal therapeutic system containing drug Glimepride with different ratios of hydrophilic and hydrophobic polymeric systems by the solvent evaporation technique. Different concentrations of oleic acid and isopropyle myristate were used to enhance the transdermal permeation of glimipride. Matrix type transdermal patches prepared by using different ratio of Eudragit RS100, HPMC100M, by using solvent evaporation techniques. All the prepared formulation were subjected to evaluation studies i.e., weight variation, thickness, drug content, moisture content, moisture uptake, flatness and in-vitro drug release. The physicochemical compatibility of the drug and the polymers studied by differential scanning calorimetry and infrared spectroscopy suggested absence of any incompatibility. Compatibility study between drug and polymer can be done by FTIR. From the all formulation batch F3 was optimized formula. Shows linear zero order release for 24 hrs with cumulative % drug diffusion of 88.34% from 4cm2 patches. It is concluded that concentration of polymer (HPMC100M) when increases into primary layer, then In-vitro diffusion rate also increases and concentration of Eudragit Rs100 when increases, the drug diffusion decreases. It provides better controlled drug release for patch.
