title: Determination of (E)-5-(2-bromovinyl)-2'-deoxyuridine in plasma and urine by capillary electrophoresis.
abstract: (E)-5-(2-Bromovinyl)-2'-deoxyuridine is an antiviral drug used for treatment of infections with Herpes simplex virus type 1 as well as Varicella zoster virus. Two fast methods for the determination of the drug and its metabolite in plasma and urine by capillary electrophoresis have been developed. The plasma method can be used for measurement of total as well as unbound drug and metabolite. Plasma and urine samples are prepared for measuring by liquid/liquid extraction resulting in a limit of quantification of 40 ng/ml for total and 10 ng/ml for free BVdU in plasma and 170 ng/ml in urine. Inter- as well as intra-day precision were found to be better than 10% and both methods have been used for drug monitoring of patients.
