ABSTRACT
Routine parenteral administration by injection serves to deliver drugs to specific body tissues. The most important routes of injection of these sterile products are intramuscular (im), intravenous (iv) and subcutaneous (sc). Basic parenteral formulation involves the selection of appropriate bases (e.g. aqueous, oily and emulsions) to achieve the desired bioavailability following injection. The detailed description of
these areas of pharmaceutics lie outside the remit of this text and the reader is refered to information provided in the further reading section of Chapter 1. This chapter focuses on advanced drug delivery and targeting systems administered via the parenteral route and serves to provide the reader with a basic understanding of the principal approaches to drug targeting.
