摘要
This article describes a rapid isocratic high-performance liquid chromatographic (HPLC) method for the simultaneous measurement of the anticonvulsants levetiracetam and zonisamide. Monitoring these drugs is important for detecting potentially toxic concentrations, particularly in patients with renal impairment, but no commercial assays are currently available. Following a liquid-liquid extraction, levetiracetam (5-150 mu g/mL) and zonisamide (5-80 mu g/mL) are quantitated by HPLC-UV. The assay's limit of quantitation, linearity, imprecision, and accuracy adequately cover the therapeutic range of these drugs. The assay should be attractive to clinical laboratories because the run time for quantification of both drugs is approximately 5 min per sample, and no interferences are currently known.
