This study aimed to produce a gastroretentive floating tablet of Metoprolol succinate and examine the effects release retardant on in vitro drug release. is β1 selective antagonist used as an Anti-hypertensive, Antiarrhythmic, Anti Angina. has 48% oral bioavailability due limited absorption from lower gastrointestinal tract. The tablets were designed increase stomach retention, prolong release,...

The objective of the study was to formulate controlled release matrix tablets of losartan Potassium by using a combination of hydrophilic synthetic polymer like poly (ethylene oxides) and natural gums like xanthan gum, karaya gum and guar gum. A combination of synthetic hydrophobic polymers like methacrylates with synthetic hydrophilic polymer like poly (ethylene oxide) was also used in the pre...

Objective: Focus of the study was to formulate Design expert Software assisted floating tablet Bisoprolol Fumarate. Fumarate is a Beta adrenergic blocking agent, used treat cardiac diseases favorable characters be formulated as sustained release Gastro retentive tablets.
 Methods: Floating Tablets were prepared by using polymers such Polyox N 12 K and Carbapol 940 P. Formulations direct co...

The aim of this study was to develop a derivative of chitosan as pharmaceutical excipient used in sustained-release matrix tablets of poorly soluble drugs. A water-soluble quaternary ammonium carboxymethylchitosan was synthesized by a two-step reaction with carboxymethylchitosan (CMCTS), decylalkyl dimethyl ammonium and epichlorohydrin. The elemental analysis showed that the target product with...

The study was aimed at developing extended release matrix tablets of poorly water-soluble diclofenac sodium and highly water-soluble metformin hydrochloride by direct compression using cashew gum, xanthan gum and hydroxypropylmethylcellulose (HPMC) as release retardants. The suitability of light grade cashew gum as a direct compression excipient was studied using the SeDeM Diagram Expert System...

The aim of the present investigation was to formulate thermally sintered floating tablets of propranolol HCl, and to study the effect of sintering conditions on drug release, as well as their in vitro buoyancy properties. A hydrophilic polymer, polyethylene oxide, was selected as a sintered polymer to retard the drug release. The formulations were prepared by a direct compression method and wer...

starch could used as ingredient fillers, binders and crushers in tablet manufacture. Amylum is also defined carbohydrates from plant, results photosynthesis, which stored part certain plant backup food mixture two type structure different polysaccharides that contains (17-20) % amylose (80-83) amylopectin. Destination study this for know the formulation of mucoadhesive tablets with fully gelati...

Oral controlled release matrix tablets of zidovudine were prepared using different proportions and different viscosity grades of hydroxypropyl methylcellulose. The effect of various formulation factors like polymer proportion, polymer viscosity and compression force on the in vitro release of drug were studied. In vitro release studies were carried out using United States Pharmacopeia (USP) typ...

Background and purpose of study: In the present investigation, an attempt was made to increase therapeutic effectiveness, reduce dose frequency and improvement in patient compliance, by developing sustained release matrix tablets of Diclofenac sodium using tamarind gum as release modifier. Methods: Six batches of sustained release matrix tablets of Diclofenac sodium were prepared by using diffe...
