Linezolid is the first antibacterial to be approved from the oxazolidinone class. The drug has substantial antimicrobial activity against Gram-positive organisms such as streptococci, staphylococci and enterococci, including species resistant to conventional antibacterial treatment. Linezolid is fully bioavailable following oral administration when compared(More)
The impact of age on linezolid disposition during the first few months of life has not been previously investigated. We characterized linezolid pharmacokinetics after a single, 10.0-mg/kg intravenous dose in 42 infants stratified as follows: group 1 (n = 9), gestational age <34 weeks and postnatal age <8 days; group 2 (n = 7), gestational age <34 weeks and(More)
Linezolid is a member of a new, unique class of synthetic antibacterial agents called oxazolidinones that are effective against gram-positive bacteria, including vancomycin-resistant organisms. We tested the hypothesis that the linezolid clearance would not be altered in subjects with renal dysfunction. Twenty-four subjects with renal function that ranged(More)
AIMS To determine the pharmacokinetics and tolerance of oral and intravenous linezolid, an oxazolidinone antibiotic, in healthy volunteers following single- and multiple-dose administration. METHODS In two randomized, double-blind, placebo-controlled, dose-escalating trials, subjects were exposed either to oral (375, 500 or 625 mg) or intravenous (500 or(More)
BACKGROUND There are a number of physiologic and developmental differences between children and adults that can influence the absorption, distribution, metabolism and elimination of a drug. Therefore it is important to determine the specific pharmacokinetic characteristics for individual drugs in pediatric patients so that appropriate age-specific dosage(More)
OBJECTIVE To evaluate the possible effects of age and sex on the pharmacokinetics of linezolid in healthy volunteers. METHODS A single 600-mg dose of linezolid was administered orally to young (18-40 years) and elderly (> or =65 years) healthy males and females. Blood and urine samples were collected until 48 h after dosing and assayed for linezolid(More)
OBJECTIVE To determine the effects of lifibrol on serum lipids in adult patients with primary hypercholesterolemia. METHODS These were two double-blind, randomized placebo-controlled studies. Each patient in each study had an 8-week dietary lead-in period on the American Heart Association Step I diet before administration of lifibrol or placebo. The first(More)
Linezolid, a new oxazolidinone antimicrobial agent, has a spectrum of activity encompassing a wide variety of Grampositive bacteria. The purpose of this study was to evaluate the pharmacokinetics of linezolid and aztreonam, an antimicrobial agent with selective activity against Gram-negative bacteria, when given alone and in combination. Healthy subjects(More)
Linezolid is a novel oxazolidinone antibiotic that has a spectrum of activity encompassing a variety of Gram-positive bacteria. The objectives of this study were twofold: (1) to compare the absorption of linezolid tablets given immediately following a high-fat meal with the absorption of tablets administered while fasting, and (2) to assess the(More)
SD0006 is a diarylpyrazole that was prepared as an inhibitor of p38 kinase-alpha (p38alpha). In vitro, SD0006 was selective for p38alpha kinase over 50 other kinases screened (including p38gamma and p38delta with modest selectivity over p38beta). Crystal structures with p38alpha show binding at the ATP site with additional residue interactions outside the(More)
