Extended release liphophilic microspheres of indomethacin were prepared using cetostearyl alcohol (CsA), stearyl alcohol (SA) and cetyl alcohol (CA) in the various drug-lipid ratios. The release of indometacin was studied on the basis of USP criteria and the effects of drug-lipid ratio, the size of microspheres and carboxymethylcellulose sodium (CMC-Na) added as a hydrophilic polymer on the drug release were investigated. In vitro dissolution studies were performed using USP XXIII apparatus I… Expand

Span 60 as a Microsphere Matrix: Preparation and in Vitro Characterization of Novel Ibuprofen-Span 60 Microspheres
Microspheres are a potential delivery system for controlled and sustained drug release. Polymeric microspheres are commonly prepared by the solvent evaporation technique whereas waxy microspheres byExpand
Evaluation of ibuprofen-loaded microspheres prepared from novel copolyesters.
Ibuprofen solubility appeared to play a dominant role in controlling release, although both encapsulation efficiency and microsphere morphology were also contributing factors. Expand
Development and comparative evaluation of extended release indomethacin capsules
The aim of this study was to develop a new extended release capsules of indomethacin. The formulation has been prepared to enhance its dissolution which could provide better oral absorption ofExpand
PEG-derivative effectively modifies the characteristics of indomethacin-PLGA microspheres destined to intra-articular administration
Preliminary cytotoxicity studies performed in rat splenocytes showed an adequate cell viability and a dose of 20–50 mg of this formulation could be appropriate to achieve both anti-angiogenic and anti-inflammatory effects. Expand
Optimization and evaluation of gastroretentive ranitidine HCl microspheres by using design expert software.
The observed responses of drug entrapment and ex vivo bioadhesion of multiunit chitosan based floating system containing Ranitidine HCl by ionotropic gelation method for gastroretentive delivery coincided well with the predicted values given by the optimization technique. Expand

In Vitro Characterization of Carbamazepine-Loaded Precifac Lipospheres
The higher the sphere size and the ratio of Precifac®, the slower is in vitro drug release, and the incorporation efficiency was found to be high at all loadings. Expand


Indomethacin sustained release from alginate-gelatin or pectin-gelatin coacervates
Abstract Gastrointestinal side effects may interrupt essential therapy with indomethacin, a non-steroidal anti-inflammatory drug. Formulation of this drug into sustained release form may reduce someExpand
Dissolution behaviour of sustained release formulations of indomethacin with Eudragit RS.
The kinetics of the release of indomethacin from Eudragit RS polymer was found to be best described by the Higuchi square root of time equation and the first order equation indicating that the release process is diffusion controlled and dependent on the initial drug concentration. Expand
Processing factors affecting particle size and in vitro drug release of sustained-release ibuprofen microspheres
Abstract Ibuprofen microspheres were prepared using an aqueous dispersion method. The method was adapted so that two processing factors, cooling time and stirring rate, could be altered. TheExpand
Calcium pectinate gel beads for controlled release drug delivery : I. Preparation and in vitro release studies
Calcium pectinate gel (CPG) beads of indomethacin, a poorly soluble drug, were prepared by dispersing indomethacin in a solution of pectin and then dropping the dispersion into calcium chlorideExpand

The use of dissolution rate data to account for differences in the absorption profiles of two controlled/modified-release capsule dosage forms of indomethacin in human volunteers
Abstract Reliance on in vitro-in vivo correlations using in vitro data obtained from a single dissolution test has frequently been shown to be misleading. The purpose of this study was to investigateExpand
