Floating Alginate Beads: Studies on Formulation Factors for Improved Drug Entrapment Efficiency and in Vitro Release

Floating calcium alginate beads based on gas-generation technique often suffer from poor drug encapsulation and rapid drug release in the acidic environment of the stomach. To overcome the above mentioned demerits, in the present study we have evaluated the influence of formulation factors such as incorporation of mixtures of gasgenerating agents (NaHCO3 and CaCO3), incorporation of gelatin typ...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Alginate-diltiazem hydrochloride beads: optimization of formulation factors, in vitro and in vivo availability.

Alginate beads containing diltiazem hydrochloride (DTZ) were prepared by the ionotropic gelation method. The effects of various factors (alginate concentration, additives type, calcium chloride concentration and curing time) on the efficiency of drug loading were investigated. The formulation containing a mixture of 0.8% methylcellulose (MC) and 4% alginate cured in 2% calcium chloride for 6 h ...

construction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers

the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...

Zinc-Alginate Beads for the Controlled Release of Rifampicin

The present study describes the preparation of a carrier system based on zinc-alginate beads and to evaluate its potential for the controlled release of rifampicin, the poorly water soluble drug using ionic gelation technique. The surface topology of the developed beads were analyzed by Scanning Electron Microscopy and the crosslinking process was investigated by Fourier Transform. Infrared spe...
