The bioavailability of some insoluble drugs is enhanced when they are dissolved in the solubilizing agent macrogol 400, although conventional hard capsules cannot tolerate the agent. This article investigates a PVA copolymer, which has been developed by the authors, examining its properties and its suitability as a material in capsule formulations.

Erythritol is a bulk sweetener polyol that is suitable for a variety of reduced-calorie and sugar-free foods. It has been part of the human diet for thousands of years because of its presence in foods such as fruit, mushrooms and fermentation-derived products including wine, soy sauce and cheese. This article investigates the properties of erythritol and describes how it can be used as a pharmaceutical excipient.

The tabletting properties of a new coprocessed excipient for direct compression were compared with a physical mixture of its components (separately and with drugs) and the individual constituents. The compaction properties were also investigated. Results indicated that the new excipient has excellent flow properties and demonstrates enhanced compressibility.

Medicines and excipients are inseparable, with few exceptions - one cannot exist without the other. The Pharmaceutical Quality Group and other international bodies have developed good manufacturing practice (GMP) standards and guidelines to facilitate the effective supply of excipients. This article discusses the definition and significance of excipients, and highlights the importance of implementing the correct excipient manufacturing controls and standards.
