Multicomponent cyclodextrin system for improvement of solubility and dissolution rate of poorly water soluble drug

Effect of Cyclodextrin Types and Co-Solvent on Solubility of a Poorly Water Soluble Drug

The aim of the study was to investigate the solubility of piroxicam (Prx) depending on the inclusion complexation with various cyclodextrins (CDs) and on ethanol as a co-solvent. The phase-solubility method was applied to determine drug solubility in binary and ternary systems. The results showed that in systems consisting of the drug dissolved in ethanol-water mixtures, the drug solubility inc...

Enhancement of Solubility and Dissolution Rate of Poorly Water Soluble Drug using Cosolvency and Solid Dispersion Techniques

The low aqueous solubility of celecoxib (CB) and thus its low bioavailability is a problem. Thus, it is suggested to improve the solubility using cosolvency and solid dispersions techniques. Pure CB has solubility of 6.26±0.23μg/ml in water but increased solubility of CB was observed with increasing concentration of cosolvents like PEG 400, ethanol and propylene glycol. Highest solubility (791....

Enhancement of Solubility and Dissolution Rate of a Poorly Water Soluble Drug Using Single and Double Hydrophilization Approach

The aim of present investigation was to improve the solubility and dissolution rate limited absorption of lornoxicam (LXM) by making solid complexes using single and double hydrophilization approaches. For this, effect of Polyvinylpyrrolidone K-30 (PVP K-30) and Poloxamer-407 (PXM407) auxiliary substances on complexation of drug with β-cyclodextrin was studied by investigating their interaction...

Dissolution rate and apparent solubility of poorly soluble drugs in biorelevant dissolution media.

A series of poorly soluble BCS class II compounds with "grease ball" characteristics were assessed for solubility and dissolution rate in biorelevant dissolution media (BDM) with the purpose of investigating which molecular structures gain most in solubility when dissolved under physiologically relevant conditions. The compounds were studied in four media (simulated intestinal fluid in fasted (...
