The physiological disposition of adriamycin and daunomycin has been studied in several animal species. Both drugs were rapidly cleared from plasma, deposited in tissues, and then excreted slowly. Drug and metabolites were excreted via the bile and urine. Daunomycin was extensively metabolized by mice, rats, dogs, and hamsters, whereas no evidence was(More)
OBJECTIVES To compare the absorption of a lysophosphatidylcholine, monoglyceride, and fatty acid matrix (organized lipid matrix, OLM) with that of a triacylglycerol (TG)-based fat meal in patients with cystic fibrosis (CF). STUDY DESIGN Five adolescents with CF and 3 control patients were given fat meals supplemented with retinyl palmitate of either OLM(More)
PURPOSE Fenretinide [N-(4-hydroxyphenyl)retinamide (4-HPR)] is a cytotoxic retinoid that suffers from a wide interpatient variation in bioavailability when delivered orally in a corn oil capsule. The poor bioavailability of the capsule formulation may have limited responses in clinical trials, and the large capsules are not suitable for young children. To(More)
Daunomycin (D1) was quantitatively converted to a metabolite, D2 (> 98% conversion), by an aerobic, cell-free system containing nicotinamide adenine dinucleotide phosphate, reduced form (NADPH) and the 100,000 x g supernatant fluid of rat kidneys. Under lowered oxygen concentrations, cell homogenates plus NADPH converted D, quantitatively to an unknown(More)
The human disposition of caffeine, theophylline, and theobromine is essentially characterized by rapid and complete gastrointestinal absorption; minimal first pass metabolism; distribution throughout the total body water; extensive and, in the case of caffeine almost complete, biotransformation in the liver; and elimination of metabolites from the body via(More)
