The objective of the study was to develop HPMC matrix tablets for oral controlled/ sustained release of water soluble Diclofenac Potassium. Sustained release matrix tablets containing 100 mg of Diclofenac Potassium were developed using different drug polymer ratio of HPMC. Tablets were prepared by direct compression. Compressed tablets were evaluated for uniformity of weight, content of active ...

In present study an attempt was made to formulate and to evaluate the sustain release Carvedilol matrix tablets by using METHOCEL K100LV CR, METHOCEL K100M CR and Xanthum Gum polymer. The tablets were prepared by direct compression method. The granules were evaluated by angle of repose, bulk density, tapped density and compressibility index, surface P. The formulated tablets were evaluated by w...

OBJECTIVE To investigate and compare the amount of fluoride release of conventional, resin modified and nanofilled resin modified glass ionomer cements. MATERIALS AND METHODS Tablets of glass-ionomer cements were immersed in deionized water and incubated at 37°C. After 1, 2, 7, 15 and 30 days, fluoride ion was measured under normal atmospheric conditions by fluoride ion selective electrode. B...

We conducted a study of the safety of controlled-release (CR) oxycodone tablets (OxyContin Tablets) administered chronically to patients with cancer-related pain in a usual clinical setting. These patients had participated in 1 of 2 double-blind, active-control studies. Our study was an open, 3-month treatment study that included 87 patients. Patients received CR oxycodone tablets every 12 hr i...

Aim The angiotensin-converting enzyme inhibitor, enalapril, is considered a first-line treatment for chronic heart failure in children. However, there lack of an age-appropriate formulation and tablet splitting, although not recommended, common, attempt, to provide suitable doses paediatric use. An analysis currently available UK brands explored the accuracy splitting low-dose tablets enalapril...

Thanks to multi-compartment systems it is possible to modify drug release. Two types of mini tablets containing 12.5 mg of ketoprofen were made: mini tablets of immediate (IR) and sustained (SR) release. Some of the tablets of immediate release were coated with an enteric coating, thereby obtaining a delayed release effect (IRc). For each tablet type, release profiles were tested in three media...

The design and fabrication of sustained/controlled release dosage forms, employing new excipients capable of extending/controlling the release of drugs from the dosage forms over prolonged periods, has worked well in achieving optimally enhanced therapeutic levels of the drugs. In this sense, the objective of this study was to investigate the suitability of selected cellulose ether derivatives ...

in this study, the effects of various hydrophilic (hpmc and carbopol 971) and plastic (ethylcellulose and eudragit rl100) polymers on the release profile of diltiazem hcl from matrix tablets were evaluated in-vitro. for this purpose, tablets containing 60 mg of diltiazem hcl along with various amounts of the aforementioned polymers were prepared using the wet granulation technique. tablets prep...
