Journal ArticleDOI
Preferential activation of capecitabine in tumor following oral administration to colorectal cancer patients.

TL;DR: Capecitabine is a novel fluoropyrimidine carbamate rationally designed to generate 5-fluorouracil preferentially in tumors, which is explained to a great extent by the activity of TP in colorectal tumor tissue, (the enzyme responsible for the conversion of 5′-DFUR to 5-FU), which is approximately four times that in adjacent healthy tissue.
Journal ArticleDOI
Clinical Pharmacokinetics of Capecitabine
TL;DR: As with other cytotoxic drugs, the interpatient variability of the pharmacokinetic parameters of cape citabine and its metabolites, 5′-deoxy-5-fluorocytidine and fluorouracil, is high and is likely to be primarily due to variability in the activity of the enzymes involved in capecitabine metabolism.
Journal Article
Effect of food on the pharmacokinetics of capecitabine and its metabolites following oral administration in cancer patients.
Bruno Reigner,Jaap Verweij,L.Y. Dirix,Jim Cassidy,Chris Twelves,David Allman,Erhard Weidekamm,Brigitte Roos,Ludger Banken,Masahiro Utoh,Osterwalder B +10 more
TL;DR: It is recommended that capecitabine be administered with food as this procedure was used in the clinical trials, and a profound influence on Cmax of cape citabine and most of its metabolites was found.
Journal ArticleDOI
Single-Ascending-Dose Pharmacokinetics and Safety of the Novel Broad-Spectrum Antifungal Triazole BAL4815 after Intravenous Infusions (50, 100, and 200 Milligrams) and Oral Administrations (100, 200, and 400 Milligrams) of Its Prodrug, BAL8557, in Healthy Volunteers
Anne Schmitt-Hoffmann,Brigitte Roos,Markus Heep,Michael Schleimer,Erhard Weidekamm,Tom Brown,Michael Roehrle,Christoph Beglinger +7 more
TL;DR: The pharmacokinetics of BAL8557 are well suited to maintaining concentrations of BAL4815 for a long period of time in the body and to enabling an effective treatment of systemic mycoses and based on the exposure data, oral bioavailability of BAL 4815 is assumed to be very high.
Journal Article
Effect of hepatic dysfunction due to liver metastases on the pharmacokinetics of capecitabine and its metabolites.
Chris Twelves,Robert Glynne-Jones,Jim Cassidy,Johannes Schüller,Timothy Goggin,Brigitte Roos,Ludger Banken,Masahiro Utoh,Erhard Weidekamm,Bruno Reigner +9 more
TL;DR: Mild to moderate hepatic dysfunction had no clinically significant influence on the pharmacokinetic parameters of capecitabine and its metabolites, and there is no need for, a priori, adjustment of the dose.
