Appraisal of the Laser Diffraction Particle-Sizing Technique
March 2nd 2005Some published articles purport to demonstrate the difficulties and problems of the laser diffraction technique without mentioning that these apparent problems are inherent in all particle-sizing techniques. This article discusses some of the advantages of using laser diffraction for particle sizing-including repeatability, ease of verification, and speed of measurement-and why it has become the preferred technique in a range of industries.
Using Extrusion-Spheronization to Develop Controlled-Release Formulations of Azithromycin
February 2nd 2005Extrusion-spheronization and pellet compression are effective means of developing first-order kinetic, controlled-release drug delivery systems of azithromycin (AZI). The authors prepared, evaluated, and optimized AZI formulations and assessed the stability of the selected formulation under accelerated storage conditions.
Toward a Generic Approach for Stress Testing of Drug Substances and Drug Products
February 2nd 2005The Impurity Profiling Group reviews stress testing according to regulatory guidance documents. The authors emphasize what should be considered for late clinical phases and for registration application dossiers.
The Preparation and Evaluation of Albendazole Microspheres for Colonic Delivery
December 2nd 2004Microspheres of Eudragit RL were developed for colonic delivery of albendazole. The effects of polymer concentration, stirring rate, and concentration of emulsifier on particle size and drug loading were studied. A comparative in vitro drug release study of the optimized formulation was carried out.
Integrated Information Management Approach to Drug Substance and Drug Product Scale-Up
November 1st 2004This article describes a novel approach to a scale-up management system, based on a holistic view of the scale-up lifecycle and an accompanying electronic development record of the information created.
