This work evaluates the physical properties affecting the flowability of the commercial rice flour. This flour/ powder were selected because of the flow issues encountered by the mills/ industries during bulk handling. A number of powder physical properties, including moisture content, particle size distribution, bulk density, compressibility index, angle of repose and co-efficient of friction ...

A series of placebo powders for inhalation was characterized regarding bulk density and powder flowability using different techniques. The powders were of the ordered mixture type and were prepared by mixing a pharmaceutical carrier grade of lactose with different fractions of intermediate sized and fine (i.e., micronized) lactose. A modified Hausner Ratio was obtained by measurement of the pou...

The present study was conducted to formulate controlled release dosage forms containing Ibuprofen with Eudragit® S 100 polymer. The tablets were formulated at three different ratios with the polymer to investigate the effect of different concentrations of polymer on in vitro drug release patterns/kinetics and in vivo absorption/pharmacokinetics. Pre-formulation studies were conducted including ...
