The aim of this investigation was to develop and optimize bisoprolol fumarate matrix tablets for sustained release application by response surface methodology based on 2(3) factorial design. The effects of the amounts of calcium alginate, HPMC K4M, and Carbopol 943 in bisoprolol fumarate matrix tablets on the properties of bisoprolol fumarate sustained release matrix tablets like drug release a...

The purpose of our study was to achieve the gastro-retentive delivery Clarithromycin by producing floating pellets get a better therapeutic effect against gastrointestinal ulcers mostly caused Hedyotis pylori. Thereby were prepared utilizing blending polymers such as Sodium (Na) Alginate and Hydroxy Propyl Methyl Cellulose (HPMCK4M & HPMC K100LV). HPMC-alginate blend containing produced hyd...

The objective of this study is to design and evaluate Ziprasidone Floating pellets, which prolongs the release rate drug while extending residence time within body environment without causing undeliterious effects subject. controlled matrix polymer granules were prepared by different granulation techniques in ratio 1:1, 1:1.5 1:2.Ziprasidone multi unit formulations comprising cellulose polymers...

Floating matrix tablets are designed to prolong the gastric residence time after oral administration, at a particular site and controlling the release of drug especially useful for achieving controlled plasma level as well as improving bioavailability. With this objective, floating dosage form containing clarithromycin as drug was designed for the treatment of Helicobacter pylori. Tablets conta...

Oral drug administration has been the predominant route for drug delivery due to the ease of administration, patient convenience and flexibility in formulations. Mucoadhesive tablets of Cephalexin monohydrate were prepared with an objective to increase the bioavailability by minimizing the first pass metabolism and also to reduce the frequency of administration. Carbopol 934p as a primary polym...

INTRODUCTION Pulsatile Drug delivery systems are gaining a lot of interest as they deliver the drug at the right site of action at the right time and in the right amount, thus providing spatial and temporal delivery and increasing patient compliance. Pulsatile Drug Delivery systems are basically time-controlled drug delivery systems in which the system controls the lag time independent of envir...

Polysaccharide mucilage derived from the seeds of Plantago major L. (family Plantaginaceae) was investigated for use in matrix formulations containing propranolol hydrochloride. HPMC K4M and tragacanth were used as standards for comparison. The hardness, tensile strength, and friability of tablets increased as the concentration of mucilage increased, indicating good compactibility of mucilage p...

The most common approach for achieving sustained drug release is by the use of hydrophilic polymeric excipients directly compressed with active ingredients into tablets. Hydrophilic polymers swell in the presence of water to form hydrogel structures from which drugs are released by slow diffusion. The purpose of this study was to prepare a floating drug delivery system of levofloxacin, a fluoro...
