Survey responses indicate that bio/pharma faces tariff-driven rising costs and supply strain, with firms aiming to boost compliance and diversification and seeking stable trade and R&D support.
X-ray Microtomography of Solid Dosage Forms
April 1st 2005X-ray microtomography has great potential for improving the understanding of the structural features of solid dosage forms and the changes in those features during manufacturing, handling, and storage. This article describes the basic principles of the technique and provides examples of its potential applications.
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.
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.
Milling Made Easy: Nanoindentation as a Predictor of Bulk Properties
December 1st 2004Size reduction of materials through comminution is employed in many industries, including agrochemicals, minerals, ceramics and pharmaceuticals. The reasons for particle size reduction depend on the industry in question. Within the pharmaceutical industry, a large percentage of products are formed from powders and undergo processing to improve dosage form properties. Particle size reduction prior to compacting to tablets can aid with dissolution and homogeneity. Such processing of powders is, in part, dependent on their mechanical properties and balancing these properties is crucial in achieving desired manufacturing performance. Generally, pilot-scale milling trials are run to determine the most effective and efficient mill and operating conditions for each material. These trials, however, require relatively large quantities of material as well as time, and are normally run in early development when sufficient material becomes available. Hence, it would be highly beneficial to identify a physical property..
Aseptic Processing: A Review of Current Industry Practice
October 2nd 2004The authors review current industry practices and regulatory expectations for the aseptic processing of sterile drugs. They compare and outline critical issues in current manufacturing technology and capabilities with regulatory requirements.
