Recent applications of electrochemical techniques to the analysis of pharmaceuticals.

The past decade has revealed a remarkable and renewed interest in the application of electrochemical techniques to the analysis of drugs and pharmaceuticals. In addition, several of these techniques are now being employed to elucidate electrode processes by studying the mechanisms involved in organic redox reactions. The renewed interest in electrochemical techniques can be attributed in part to more sophisticated instrumentation and to an increased understanding of the techniques themselves. This paper selectively reviews recent applications of the following electrochemical modes in the analysis of drugs and pharmaceuticals: amperometry, conductometry, coulometry, ion-selective electrodes, potentiometry, stripping voltammetry (anodic and cathodic) and voltammetry.
