By enhancing stability and in vitro drug-release characteristics, limonene enantiomers are a natural-source alternative for developing and characterizing self-nanoemulsified drug delivery systems.

The process of extrusion/spheronization used to produce spherical granules frequently relies on formulations containing microcrystalline cellulose (MCC). This excipient can hold water, even when pressure is applied, and form "pastes" that have suitable rheological properties, which allow both extrusion and subsequent spheronization to produce uniform spherical granules. This article describes a new approach to providing paste systems with appropriate characteristics. This can be achieved by incorporating glyceryl monostearate (GMS) into the formulation. It was found that the inclusion of GMS in formulations provides a useful alternative to MCC as an effective excipient to aid the preparation of spherical granules, allowing the incorporation of drug loads as high as 90%.

Previous articles have presented a general review of the different types of spheres that can be obtained with a rotary fluidized bed process.1,2 This two-part study focusses on lipid spheres that can be prepared using hydrogenated castor oil, as well as examining the feasibility of the process and the main characteristics of the spheres obtained.

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.
