A high performance liquid chromatographic assay for the quantitative determination of apomorphine in human plasma is described. Sample clean-up and concentration was optimised using solid-phase extraction on C18 cartridges, enabling rapid and sensitive determination of apomorphine and potential metabolites. The limit of apomorphine quantification, using fluorescence detection, was 0.5 ng/mL. The assay was stability-indicating, and allowed the detection of analytes in the presence of commonly co-administered anti-Parkinsonian drugs. Apomorphine was stable in frozen plasma containing 0.14% (w/v) ascorbic acid for 98 days, and through four freeze-thaw cycles. The assay has been used in clinical pharmacokinetic studies of apomorphine in patients with Parkinson's disease, and in preliminary studies of novel apomorphine delivery devices in volunteers.
