Plasma pharmacokinetics and tissue penetration of a novel antifungal triazole, Bay R 3783, and its long-lasting active metabolite, Bay U 3625, in rabbits.

The plasma pharmacokinetics and tissue penetration of Bay R 3783 (BR), a new antifungal triazole, and one of its active metabolites, Bay U 3625 (BU), were studied in rabbits. Plasma levels of BR and BU were determined simultaneously in five rabbits for six days after a single oral dose of 20 or 40 mg/kg BR
