Targeted liposomes can be categorized as either immunoliposomes or ligand-targeted liposomes. The author provides a brief review of tumour-specific and liver-targeted cationic liposomes and strategies for the development of liposome?ligand complexes.

This article describes the use of a one-pot processor for the cleaning and cleaning validation of two drug compounds - water-soluble theophylline and water-insoluble mebendazole. Both substances were produced using wet granulation and microwave drying, after which the processor was cleaned using its clean-in-place (CIP) system. Swab samples were taken from areas considered critical during processing and analysed for remains of active ingredient. It was concluded from the results that the processor's CIP system is capable of removing both moieties to a level well within accepted regulations.
