An HPLC method has been developed for the determination of pseudoephedrine in plasma using column switching. Preparation of the sample was simple in that only 1000 mL of water was added to 200 mL of plasma before injection. A 900 mL aliquot was injected onto the precolumn. Double distilled water was

Abstract
Melagatran is an active thrombin inhibitor showing oral and parenteral bioavailability for antithrombotic therapy. A simple and convenient liquid chromatographic method has been developed and applied to the analysis of melagatran in rabbit plasma. The clean‐up and separation of the sample solutions were performed by automated on‐line column switching HPLC. The method validation shows the suitability of the column switching liquid chromatographic system for the quantitation of melagatran in biological fluids. Copyright © 2003 John Wiley & Sons, Ltd.
