Subcutaneous injections are widely utilised as a delivery route for compounds with limited oral bioavailability or as a means to modify or extend the release profile. In this review, factors affecting absorption from the subcutaneous space are discussed with particular emphasis on differential drug absorption into either the underlying blood or lymphatic capillaries. Formulation and targeted delivery approaches, which utilise the subcutaneous administration route, are reviewed with reference to associated technologies and future challenges. © 2005 Elsevier Ltd.
