ANALYSIS OF BASIC PSYCHOTROPIC DRUGS IN BIOLOGICAL FLUIDS AND TISSUES BY REVERSED-PHASE HIGH PERFORMANCE LIQUID CHROMATOGRAPHY

Acta Pol Pharm. 2017 Mar;74(2):331-346.

Abstract

The review of the RP HPLC analysis of basic psychotropic drugs is presented. It contains sample preparation methods with centrifugation, protein precipitation, liquid-liquid extraction (LLE), dispersive liquid-liquid microextraction (DLLME), solid-phase extraction (SPE), solid-phase microextraction (SPME), microwave-assisted extraction (MAE) and RP-HPLC analysis. Chromatographic behavior of basic drugs in aqueous media - eluents used in reversed phase systems is discussed. Methods of blocking of residue surface silanols' interaction are mentioned. Analytical methods used for the analysis are divided into parts according with the above methods: the use of low-pH eluents, the use of high-pH eluents, the use of silanol blockers, special stationary phases for basic analytes. Literature connected with the sample preparation methods and analytical systems for the drug analysis are cited in details and presented also in Table 1.
