The objective of the present work was to develop Gastro retentive dosage forms which would remain in the stomach and upper part or GIT for a prolonged period of time thereby maximizing the drug release at desired site within the time before GRDFs left the stomach and upper part of the GIT, has provoked a great deal of increased interest in the formulation of such drug as floating drug delivery systems. Levofloxacin, (BCS class I) is a fluoroquinolone anti-bacterial agent. The rationale for the formulation of floating matrix tablet are acidic solubility of levofloxacin, residence of Halicobactor pylori mainly in sub region of stomach and the overdosing associated adverse effect due to continuous intake of drug in acute infection. A simple visible spectrophotometric method was employed for the estimation of levofloxacin at 294 nm and Beer’s law is obeyed in the concentration range of 2-10 μg /ml. Floating matrix tablet of levofloxacin was prepared by direct compression method using different polymers like hydroxyl propyl methyl cellulose (HPMC K4) and carbopol 934 as matrix formation polymers, sodium bicarbonate and citric acid was used as gas generating agents. The FTIR spectra of the levofloxacin and other excipients alone and in combination show the compatibility of the drug and excipients. Six formulations of different polymer percentages were formulated (F1-F6). Pre-compression parameters were evaluated. The influence of matrix forming agents and binary mixtures of them on levofloxacin release was investigated. The formulated tablets were characterized by hardness, friability, thickness, weight variation and in vitro drug release. The formulated tablets had acceptable physicochemical characters. The data obtained from the in-vitro dissolution studies of optimized batch F4were fitted in different models. The optimized formulation F4 showed 99.25% drug content and swelling index of 79.85 %. Drug release mechanism was found to be first order kinetics. Levofloxacin floating tablets exhibited increased gastric residence time, there by improved bioavailability and therapeutic effect of the drug.

Fast Disintegrating Tablet

Objective: The aim of the present investigation was to design and evaluate orally disintegrating tablet (ODT) of Ibuprofen, a NSAID drug used for the treatment of arthritis with a view to improve its oral bioavailability. The focus of the current study was to develop ODT of Ibuprofen using super disintegrants for ease of administration and its physicochemical characterization.Methods: Tablets were made from blends by direct compression method. All the ingredients were passed through mesh no. 80. All the ingredients were co-ground in a pestle motor. The resulting blend was lubricated with magnesium stearate and compressed into tablets using the Cadmach single punch (round shaped, 8 mm thick) machine.Results: Physicals parameters of the prepared tablets like Hardness, Weight variation, Friability, thickness, drug content etc. found within the limits. The disintegration time of prepared ODTs was in the range of 45 to 55 seconds. In vitro dispersion time was found to be 22 to 52 seconds which may be attributed to faster uptake of water due to the porous structure formed by super disintegrants. Short disintegration and faster release of ibuprofen were observed with Cross carmellose sodium as compared to sodium starch glycollate.Conclusion: It is concluded that F3 offered the relatively rapid release of Ibuprofen when compared with other formulations. The increase in the concentrations of super disintegrants may lead to increase in the drug release. The formulation prepared with cross carmellose sodium was offered the relatively rapid release of Ibuprofen when compared with other concentrations of both the super disintegrant.

The aim of the present work was to develop sustained release Lornoxicam matrix tablets with polymers like HPMC K15M, Ethyl cellulose, and Crospovidone as carriers in varying quantities. Direct compression was used to make matrix tablets. Various assessment parameters, such as hardness, friability, thickness, percent drug content, weight variation, and so on, were applied to the prepared formulations. In vitro dissolution studies were carried out for 24 hrs. The tablets were subjected to in-vitro drug release in (pH 1.2) for first 2 hrs. Then followed by (pH 6.8) phosphate buffer for next 22 hrs. And the results showed that among the six formulations FL3 showed good dissolution profile to control the drug release respectively. The drug and polymer compatibility were tested using FT-IR spectroscopy, which revealed that the drug was compatible with all polymers. It is also required to design an appropriate prolonged release formulation for Lornoxicam in order to maintain the drug's release. Hence by using the compatible polymers sustained release tablets were formulated and subjected for various types of evaluation parameters like friability, hardness, drug content and dissolution behaviour. Finally, the findings reveal that the prepared sustained release matrix tablets of lornoxicam have improved efficacy and patient compliance.

The objective of the present study was to develop a once-daily sustained release matrix tablet of Aceclofenac using hydroxypropyl methyl cellulose (Methocel K 100M CR) as release controlling factor and to  evaluate drug release parameters as per various release kinetic models. The tablets were prepared by direct  compression method. The powder blends were evaluated for angle of repose, loose bulk density, tapped bulk density,  compressibility index, total porosity and drug content etc. The tablets were subjected to thickness, weight variation test, drug content, hardness, friability and in vitro release studies. The in vitro dissolution study was carried out for 24  hours using United States Pharmacopoeia (USP) 22 paddle-type dissolution apparatus in phosphate buffer (pH 7.4). The powder blends showed satisfactory flow properties, compressibility index and drug content etc. All the tablet formulations showed acceptable pharmacotechnical properties and complied with pharmacopoeial specifications. The results of dissolution studies indicated that the formulation F-3 (40% Methocel K100M CR of total weight of tablet) could extend the drug release up to 24 hours and the total release pattern was very close to the theoretical release profile. By comparing the dissolution profiles with the originator brand of Arrestin SR, the formulation F-3 exhibited drug release profile like originator brand. From this study, a decrease in release kinetics of the drug was observed by  increasing the polymer concentration. Kinetic modeling of in vitro dissolution profiles revealed the drug release mechanism ranges from diffusion controlled or Fickian transport to anomalous type or non-Fickian transport, which  was only dependent on the type and amount of polymer used. The drug release followed both diffusion and erosion  mechanism in all cases. The drug release from the formulation (F-3) was satisfactory after 3 months storage in 400C  and 75% RH. Besides, this study explored both of the optimum concentration and effect of polymer(s) on  Aceclofenac release pattern from the tablet matrix for 24 hour period. The matrix tablet of Aceclofenac using HPMC  with molecular weight of K100M controlled the drug release effectively for 24 hours; hence the formulation can be  considered as a once daily sustained release tablet of Aceclofenac in order to improve patient compliance.

An attempt was to formulate the oral sustained release Metformin hydrochloride matrix tablets by using hydroxyl methyl cellulose polymer (HPMC) as rate controlling factor and to evaluate drug release parameters as per various release kinetic models. The tablets were prepared by direct compression method. The granules were evaluated for angle of repose, loose bulk density, tapped bulk density, compressibility index, total porosity, drug content etc. and showed satisfactory results. The tablets were subjected to thickness, weight variation test, drug content, hardness, friability and in vitro release studies. The in vitro dissolution study was carried out for 8 hours using United States Pharmacopoeia USP 2 (paddle-type dissolution apparatus) in phosphate buffer (pH 7.4) as dissolution media. All the tablet formulations showed acceptable pharmacotechnical properties and complied with pharmacopoeial specifications. The release mechanisms were explored and explained with zero order, first order, Higuchi, Korsmeyer and Hixson-Crowell equations. The results indicated that a decrease in release kinetics of the drug was observed by increasing the polymer concentration. Kinetic modeling of in vitro dissolution profiles revealed the drug release mechanism ranges from diffusion controlled or Fickian transport to anomalous type or non-Fickian transport, which was only dependent on the type and amount of polymer used. The drug release followed both diffusion and erosion mechanism in all cases. Besides, this study explored both of the optimum concentration and the effect of polymer on drug release pattern from the tablet matrix for 8 hours period.
