Stir bar sorptive extraction for central nervous system drugs from biological fluids

A review with 75 references is presented that deals with the reported methods for analysis of some important central nervous system (CNS) drugs in biological fluids utilizing stir bar sorptive extraction (SBSE) technique covering the years from 2000 to 2008. The theoretical aspects of SBSE, as well as an significant number of applications have been published, showing the advantages of this technique over the classical extraction techniques (liquid–liquid extraction (LLE) and solid-phase extraction (SFE). In this review, recent SBSE developments and a focus on the development of new instrumental approaches and sorbent phases are presented.
