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

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.

The current research work involves preparation of fast dissolving tablets of Aceclofenac by direct compression method using different concentrations of Lepidium sativum mucilage as natural superdisintegrant. A two-factor three-level (32) factorial design is being used to optimize the formulation. Nine formulation batches (D1–D9) were prepared accordingly. Two factors as independent variables (X1-amount of β-cyclodextrin and X2-amount of Lepidium sativum mucilage) were taken with three levels (+1,0,-1). The levels of two factors were selected on the basis of preliminary experiments conducted and their effect on three dependent variables (disintegration time, wetting time, and in vitro drug release) was studied along with their % prediction error. All the active blends were evaluated for postcompression parameters (angle of repose, Carr’s index, Hausner ratio, etc.) and the tablets were evaluated for postcompression parameters (weight variation, hardness, and friability, wetting time, disintegration time, water absorption ratio, and in vitro drug release studies). The optimum batch was further used for SEM and stability studies. Formulation D5 was selected by the Design-Expert software which exhibited DT (15.5 sec), WT (18.94 sec), and in vitro drug release (100%) within 15 minutes.

Background: Moxifloxacin is a BCS class I drug used in the treatment of bacterial conjunctivitis and keratitis. Despite its high water solubility, it possesses limited bioavailability due to anatomical and physiological constraints associated with the eyes which required multiple administrations to achieve a therapeutic effect. Objective: In order to prolong drug release and to improve antibacterial efficacy for the treatment of bacterial keratitis and conjunctivitis, moxifloxacin loaded nanoemulsion was developed. Methods: The concentration of oil (oleic acid), surfactant (tween 80), and cosurfactant (propylene glycol) were optimized by employing a 3-level 2-factorial design of experiment for the development of nanoemulsion. The developed nanoemulsion was characterized by particle size distribution, viscosity, refractive index, pH, drug content and release, transmission electron microscopy (TEM), and antibacterial study. The compatibility of the drug with the excipients was accessed by Fourier transform infrared spectroscopy (FTIR). Result: The average globule size was found to be 198.20 nm. The TEM study reveals the globules were nearly spherical and are well distributed. In vitro drug release profile for nanoemulsion shown sustained drug release (60.12% at the end of 6 h) compared to drug solution, where complete drug released within 2 h. The antibacterial effectiveness of the drug-loaded nanoemulsion was improved against S. aureus compared with the marketed formulation. Conclusion: The formulated sustained release nanoemulsion could be a promising alternative to eye drop with improved patient compliance by minimizing dosing frequency with improved antibacterial activity.
