Liquid chromatography/electrochemistry (LCEC) has become recognized as a powerful tool for the trace determination of easily oxidizable and reducible compounds. This is because detection of as little as 0.1 pmol of material is readily accomplished with relatively simple and inexpensive equipment. Initial interest in LCEC was generated by the determination of several aromatic metabolites of tyrosine in the central nervous system. However, the application of LCEC into other areas of analysis including pharmaceutical analysis and especially pharmacokinetic and pharmacodynamic studies has become common. ... 

The combination of a pharmacodynamic model with a modem technique such as microdialysis is an attractive solution to assess pharmacokinetic/pharmacodyamic (PK/PD) relationships. Two separate stndies supported this idea. Esterom Solution is derived from the esterification of benzoylmethylecgonine (cocaine) and contains a mixture of components (McDonald and Lunte, 2003). This solution is intended to be a topical analgesic to relieve pain and increase the range of motion in patients with acute inflammation. A pharmacodynamic model can only provide information about the qualitative reduction in pain as a result of topical application of complete mixture. The dermal microdialysis analysis of tins mixture revealed that the only component that penetrated the skin was hydroxypropyl braizoylecgonine (McDonald and Lunte, 2003). Thus, the analgesic activity of the I Lstcrom Solution was caused by one component. 

In addition to these qualitative studies, quantitative bioanalysis, e.g., in preclinical and clinical studies to provide pharmacokinetic and pharmacodynamic data, is an essential part of drug development. Quantitative bioanalysis is the most important application area of LC-MS, in terms of number of instruments applied and the number of analyses performed. Fast, high-throughput, and routine quantitative analysis by LC-MS also demands fast and automated sample pretreatment strategies and advanced data-processing software.
