High-performance liquid chromatographic method for the enantioselective analysis of mefloquine in plasma and urine.
An HPLC method for analysis of the enantiomers of the antimalarial drug mefloquine is presented. A complete resolution of (-)-(11S,2'R) and (+)-(11R,2'S) erythro-mefloquine from plasma and urine was obtained on a commercial AGP column. Mefloquine enantiomers were detected by UV at 222 nm. The separation factor (alpha) at +20 degrees C was 1.50. The limit of determination (coefficient of variation 4.0%) for the enantiomeric ratio (11S,2'R)/(11R,2'S) is 15:1 at a total mefloquine concentration of 1.6 mM.
