Studies on the Disposition of Fadrozole Hydrochloride (CGS 16949A) (I): Absorption, Distribution, Metabolism and Excretion after a Single Oral Administration to Rats.

Absorption, distribution, metabolism, and excretion of donepezil (Aricept) after a single oral administration to Rat.

Donepezil hydrochloride (Aricept) is a drug for the treatment of Alzheimer's disease. The absorption, distribution, metabolism, and excretion of donepezil were investigated in male Sprague-Dawley rats after a single oral administration. Orally administered (14)C-labeled donepezil was absorbed rapidly. The plasma level of unchanged donepezil declined more rapidly than that of radioactivity, and ...

Metabolism and disposition of dasatinib after oral administration to humans.

SPRYCEL (dasatinib, BMS-354825; Bristol-Myers Squibb, Princeton, NJ), a multiple kinase inhibitor, is currently approved to treat chronic myelogenous leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia tumors in patients who are resistant or intolerant to imatinib mesylate (Gleevec; Novartis, Basel, Switzerland). After a 100-mg single p.o. dose of [(14)C]dasatinib to heal...

Absorption and disposition of ginsenosides after oral administration of Panax notoginseng extract to rats.

Panax notoginseng (Sanqi) is a cardiovascular herb containing ginsenosides that are believed to be responsible for the therapeutic effects of Sanqi. The aim of this study was to evaluate rat exposure to ginsenosides after oral administration of Sanqi extract and to identify the key factors affecting their absorption and disposition. Ginsenosides were administered to rats, either in the form of ...

Disposition Kinetics of Amoxicillin in Healthy, Hepatopathic and Nephropathic Conditions in Chicken after Single Oral Administration

Fifteen broiler chickens (COBB 400) of 42 days of age weighing 1.8 to 2.0 kg were equally divided into 3 groups, each consisting of 5 birds. Hepatopathy was induced by oral administration of paracetamol while nephropathy was induced by intravenous administration of uranyl nitrate. Kinetic study was investigated in healthy, hepatopathic and nephropathic birds following single oral administration...
