We have previously reported that human total body clearance (CL) and steady-state volume of distribution (Vss) of monoclonal antibodies (mAbs) could be predicted reasonably well from monkey data alone using simple allometry with scaling exponents of 0.79 and 1.12 (for soluble targets), and 0.96 and 1.00 (for membrane-bound targets). In the present study, to predict the plasma concentration-time...
The functionality of the correction factors, maximum life-span potential (MLP), and brain weight (BrW) used in allometry is mathematically described. Correction by MLP or BrW is equivalent to a multiplication of some constants by the predicted values in humans from simple allometry, but they have no relationship to measured pharmacokinetic parameters in the animal species. The values of these c...
BACKGROUND Estimation of pharmacokinetic parameters after intermittent intravenous infusion (III) of antibiotics, such as aminoglycosides or vancomycin, has traditionally been a difficult subject for students in clinical pharmacology or pharmacokinetic courses. Additionally, samples taken at different intervals during repeated dose therapy require manipulation of sampling times before accurate ...
Voriconazole is an antifungal triazole, approved for management of invasive fungal diseases in patients. It is absorbed during two hours and its serum levels will be above 90%, based on the underlying factors, when the drug is administered orally. Voriconazole shows a propotional increase in an area under the plasma concentration-time curve (AUC), with increasing dose. Plasma protein binding of...
A comparative pharmacokinetic study of berberine and palmatine after oral administration of Rhizoma Coptidis extract (96 mg/kg, containing berberine 22 mg/kg and palmatine 5 mg/kg based on body weight) was performed in normal and postinflammation irritable bowel syndrome (PI-IBS) rats, induced by intracolonic instillation of acetic acid and restraint stress. Quantification of berberine and palm...
OBJECTIVES The discovery and development of TB drugs has met limited success, with two new drugs approved over the last 40 years. Part of the difficulty resides in the lack of well-established in vitro or in vivo targets of potency and physicochemical and pharmacokinetic parameters. In an attempt to benchmark and compare such properties for anti-TB agents, we have experimentally determined and ...
The pharmacokinetic profile of gallocatechin-7-gallate (J10688) was studied in rats after intravenous administration. Male and female Sprague-Dawley (SD) rats received 1, 3, and 10 mg/kg (i.v.) of J10688 and plasma drug concentrations were determined by a high performance liquid chromatography-mass spectrometry (LC-MS) method. The pharmacokinetic software Data Analysis System (Version 3.0) was ...
