Metabolism of patupilone in patients with advanced solid tumor malignancies.

A phase 1, open-label, non-randomized, single center study was conducted to determine the pharmacokinetics, distribution, metabolism, elimination, and mass balance of patupilone in patients with advanced solid tumors. Five patients with advanced solid tumors received 10 mg/m(2) (1.1 MBq) of (14) C-radiolabeled patupilone at cycle 1 as a 20-minute intravenous infusion every 3 weeks until disease progression.

Metabolism and disposition of the oral absorption enhancer 14C-radiolabeled 8-(N-2-hydroxy-5-chlorobenzoyl)-amino-caprylic acid (5-CNAC) in healthy postmenopausal women and supplementary investigations in vitro.

8-(N-2-hydroxy-5-chlorobenzoyl)-amino-caprylic acid (5-CNAC), a compound lacking pharmacological activity enhances the absorption of salmon calcitonin, when co-administered. Disposition and biotransformation of 5-CNAC was studied in six healthy postmenopausal women following a single oral dose of 200mg (14)C-radiolabeled 5-CNAC (as disodium monohydrate salt). Blood, plasma, urine and feces collected over 7 days were analyzed for radioactivity.

Safety and pharmacokinetics of a single 1500-mg dose of famciclovir in adolescents with recurrent herpes labialis.

An open-label study evaluated the safety (n = 53) and pharmacokinetics (n = 8) of single-dose therapy with 1500 mg famciclovir (prodrug of penciclovir) for recurrent herpes labialis in adolescents. Mean Cmax, mean AUC0-∞, and clearance for penciclovir were 9.37 μg/mL, 31.

Percutaneous absorption of pimecrolimus is not increased in patients with moderate to severe atopic dermatitis when pimecrolimus cream 1% is applied under occlusion.

Aim: To evaluate the systemic exposure of pimecrolimus cream 1% applied under occlusion in atopic dermatitis (AD) patients.

Methods: A noncomparative, open-label study conducted in 3 groups of moderate to severe AD patients: A (adults, n = 9), B (adolescents, n = 4) and C (children, n = 6). Pimecrolimus cream 1% was applied twice daily for 8.

Pharmacokinetics, metabolism, and disposition of deferasirox in beta-thalassemic patients with transfusion-dependent iron overload who are at pharmacokinetic steady state.

Deferasirox (ICL670) is a novel once-daily, orally administered iron chelator to treat chronic iron overload in patients with transfusion-dependent anemias. Absorption, distribution, metabolism, and excretion of [14C]deferasirox at pharmacokinetic steady state was investigated in five adult beta-thalassemic patients. Deferasirox (1000 mg) was given orally once daily for 6 days to achieve steady state.
