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.

Using melt extrusion to prepare glass solutions of poorly water-soluble drugs with hydrophilic excipients offers an exciting and advantageous alternative to existing formulation methods such as spray-drying and co-melting. Investigating potential methods to increase water solubility begins early in drug development. Techniques described in this paper show how only a small quantity of drug can be used to determine its suitability for melt extrusion, allowing the method to be considered at the same time as salt screening and particle size reduction work, and could speed up the formulation process.
