Abstract

Scopolamine is an anticholinergic alkaloid that is widely used in the form of a transdermal system to manage nausea associated with motion sickness. Currently available methods to quantify scopolamine require large sample volumes and involve cumbersome sample preparation. In this work, a simple method for the rapid separation and sensitive quantification of scopolamine in human serum was developed. Scopolamine was extracted from 0.5 mL of human serum using solid-phase extraction. The extracted samples were injected onto Zorbax XDB-C18 column (4.6 × 50 mm, 1.8 μm, and 600 bar) on an Agilent 1200 series HPLC. The chromatographic separation involved gradient elution with water and acetonitrile containing 0.1% v/v formic acid as a mobile phase. The samples were quantified in positive ion mode using a TSQ Quantum triple quadrupole mass spectrometer. The assay was validated and found to be linear over a concentration range of 5–5000 pg/mL. The total assay precision and accuracy was 6.3% and 96%, respectively. The lower limit of quantification (LLOQ) of the assay was 5 pg/mL. The assay was used in a human pharmacokinetic study to measure the concentration of scopolamine in serum after an administering scopolamine as transdermal delivery system or as an intravenous bolus dose.
