Solubility Enhancement of a Poorly Water Soluble Drug by Forming Solid Dispersions using Mechanochemical Activation
Mechanochemical activation is a practical cogrinding operation used to obtain a solid dispersion of a poorly water soluble drug through changes in the solid state molecular aggregation of drug-carrier mixtures and the formation of noncovalent interactions (hydrogen bonds) between two crystalline solids such as a soluble carrier, lactose, and a poorly soluble drug, indomethacin, in order to impr...
متن کاملPreparation and characterization of celecoxib solid dispersions; comparison of poloxamer-188 and PVP-K30 as carriers
Objective(s):Solid dispersion formulation is the most promising strategy to improve oral bioavailability of poorly water soluble drugs. The aim of this study was to compare the effect of polyvinylpyrrolidone K30 (PVP) and poloxamer-188 (PLX) as carrier in solid dispersion formulations of celecoxib (CLX). Materials and Methods: Solid dispersions of CLX:PVP or CLX:PLX were prepared at different r...
متن کاملImproved dissolution of a poorly water soluble drug in solid dispersions with polymeric and non-polymeric hydrophilic additives.
Irbesartan (IBS) is a hydrophobic drug with poor aqueous solubility and dissolution rate. Solid dispersions (SDs) of IBS were prepared with both small molecules (tartaric acid and mannitol) and polymeric additives (polyvinyl-pyrrolidone, PVP, and hydroxypropyl methylcellulose, HPMC). A 9.5 and 7 folds enhancement in solubility over the crystalline form (14.6 microg mL-1) was observed for tartar...
متن کاملDissolution Behavior and Thermodynamic Stability of Fused-Sugar Dispersions of a Poorly Water-Soluble Drug
The current research was undertaken to develop and evaluate dissolution profiles of thermodynamically stabilized sugar dispersions of the poorly water-soluble, model drug etoricoxib (ETX). Fused-sugar dispersions were formulated using sorbitol, xylitol, and maltose separately, and the binary systems were stabilized by incorporation of the antiplasticizing agents poloxamer 407 and PVP K30 to obt...
متن کاملCharacterization of Olanzapine – Solid dispersions.
Aim: To enhance the aqueous solubility of olanzapine by using the Solid dispersion technique. Solid dispersions of Olanzapine were prepared by the dispersion method using using PGS and SSG as carriers. Drug:carrier ratios such as 1:1, 1:2, 1:4, 1:6, 1:8 and 1:10 were tried for optimization. Characterization was done by phase solubility, in vitro release, saturation solubility, permeation, wetta...
