Meloxicam is a poorly water soluble non steroidal anti-inflammatory drug and antipyretic agent. The aim of the present work was to investigate the effect of different types of carriers on in vitro dissolution of meloxicam. Meloxicam solid dispersions were prepared by physical mixing, co-grinding and solvent evaporation methods with polyethylene glycol (PEG) 6000. The effect of solubilization by...

Naproxen is a poor water soluble, non-steroidal analgesic and anti-inflammatory drug. The enhancement of oral bioavailability of poor water soluble drugs remains one of the most challenging aspects of drug development. Although salt formation, solubilization and particle size reduction have commonly been used to increase dissolution rate and thereby oral absorption and bioavailability of low wa...

the present study investigates the possibility of using poloxamers as solubility and dissolution rate enhancing agents of poorly water soluble bioactive constituent patchouli alcohol (pa) that can be used for the preparation of immediate release pellets formulation. two commercially available grades poloxamer 188 (p 188) and poloxamer 407 (p 407) were selected, and solid dispersions (sds) conta...

diosmin, a vascular-protecting agent, is practically insoluble in water, and its oral absorption is limited by its extremely low dissolution rate. in this study, β-cyclodextrin (βcd) and 2-hydroxypropyl-β-cyclodextrin (hpβcd) were obtained to improve the solubility and dissolution rate of diosmin. phase solubility studies of diosmin with βcd and hpβcd in distilled water were conducted to charac...

PURPOSE The aim of this work was to evaluate the influence of crystal habit on the dissolution and in vitro antibacterial and anitiprotozoal activity of sulfadimidine:4-aminosalicylic acid cocrystals. METHODS Cocrystals were produced via milling or solvent mediated processes. In vitro dissolution was carried out in the flow-through apparatus, with shadowgraph imaging and mechanistic mathemati...

A good correlation should be obtained between data derived from in vitro dissolution and bioavailability studies on drug delivery systems if bioavailability parameters are to be reliably predicted from the in vitro dissolution variables. This study compares the in vivo absorption with the in vitro dissolution profiles into various dissolution media of a novel controlled release theophylline cap...

Rapid and consistent in-vivo drug dissolution is critical for drug absorption. In-vitro dissolutions tests are used to predict in-vivo disintegration and dissolution properties of drug products. The in-vitro disintegration and dissolution times of tablets and capsules can vary significantly based on their composition and processing. Though small differences in-vitro dissolution are not expected...

A dry process induced phase transited, non disintegrating, controlled release, in situ formed asymmetric membrane capsular system for poorly water soluble drug, ketoprofen, was developed and evaluated both in vitro and in vivo for osmotic and controlled release of the drug. In situ formed asymmetric membrane capsules were prepared using fabricated glass capsule holders via dry, phase inversion ...

The objectives of present investigations were to optimize concentration of oil, surfactant and cosurfactant by pseudoternary phase diagrams and to develop a stable formulation of self emulsifying drug delivery system (SEDDS) in order to enhance the dissolution rate of poorly soluble Irbesartan (IBS) by SEDDS. Pseudoternary phase diagrams were constructed to identify the self emulsifying region....
