AIM The aim of this study was to investigate the activity of the drug-metabolizing enzyme cytochrome P450 (CYP) 2B6 before and after in vivo induction by rifampin (INN, rifampicin) in white subjects and Chinese subjects by use of the probe drug bupropion (INN, amfebutamone). METHODS Healthy male white subjects (n = 9) and Chinese subjects (n = 9) (age(More)
BACKGROUND We aimed to investigate whether the addition of non-steroidal anti-inflammatory drugs or spinal manipulative therapy, or both, would result in faster recovery for patients with acute low back pain receiving recommended first-line care. METHODS 240 patients with acute low back pain who had seen their general practitioner and had been given(More)
1. The disposition of warfarin enantiomers and metabolites has been studied in 36 patients receiving chronic rac-warfarin therapy, titrated to approximately the same anticoagulant response. 2. A stereoselective h.p.l.c. assay was employed to determine the concentrations of (R)- and (S)-warfarin, (R,S)-warfarin alcohol and (S)-7-hydroxywarfarin in plasma and(More)
The clinical presentation of a hot swollen joint is common and has wide differential diagnosis. The most serious is septic arthritis, with a case fatality of 11%. Delayed or inadequate treatment leads to joint damage. These guidelines focus on the diagnosis and management of septic arthritis. Hot swollen joints commonly have other underlying diagnoses,(More)
Allopurinol is the drug most widely used to lower the blood concentrations of urate and, therefore, to decrease the number of repeated attacks of gout. Allopurinol is rapidly and extensively metabolised to oxypurinol (oxipurinol), and the hypouricaemic efficacy of allopurinol is due very largely to this metabolite. The pharmacokinetic parameters of(More)
OBJECTIVE To apply a combined pharmacokinetic-pharmacodynamic model to data from warfarin drug interaction studies. METHODS The pharmacokinetic model for warfarin enantiomers combined a common first-order absorption process with individual clearance and volume of distribution values and is based on unbound drug. The complete pharmacodynamic model(More)
Celecoxib, a nonsteroidal anti-inflammatory drug (NSAID), is the first specific inhibitor of cyclo-oxygenase-2 (COX-2) approved to treat patients with rheumatism and osteoarthritis. Preliminary data suggest that celecoxib also has analgesic and anticancer properties. The selective inhibition of COX-2 is thought to lead to a reduction in the unwanted effects(More)
OBJECTIVES To examine the hemodynamic effects of milrinone given prophylactically to very preterm infants at high risk of low superior vena cava (SVC) flow and to investigate the preliminary efficacy and safety of an optimal dose. STUDY DESIGN This was a prospective, open-label study in two stages. The first involved dose escalation in two cohorts.(More)
OBJECTIVE This study aimed to determine an optimal discriminating number of concomitant medications associated with geriatric syndromes, functional outcomes, and mortality in community-dwelling older men. STUDY DESIGN AND SETTING Older men aged ≥ 70 years (n=1,705), enrolled in the Concord Health and Aging in Men Project were studied. Receiver operating(More)
The major site of action for nonsteroidal anti-inflammatory drugs (NSAIDs) in the treatment of rheumatic diseases is probably within the synovial compartment. There has been little work on the disposition of NSAIDs in the synovium and most studies have involved the measurement of their concentrations in synovial fluid. The concentrations of NSAIDs are more(More)
