Abstract : A normal-phase HPLC method utilizing ion-pair extraction for the quantitation of pyridostigmine in plasma is described. The limit of quantitation was 2 ng/ml plasma; intra-day precision with coefficient of variation (CV) of 1.4% (50 ng/ml) and inter-day precision of 2.6% (50 ng/ml) were obtained. The method was designed for use in pharmacokinetic studies with the Rhesus monkey, but has been successfully adapted and applied to the analysis of plasma from rats dosed with pyridostigmine in the feed. Keywords: Blood plasma; Acetycholinesterase, Pharmicokinetics.
