High-performance liquid chromatography assay for moxifloxacin in brain tissue and plasma: validation in a pharmacokinetic study in a murine model of cerebral listeriosis.

Moxifloxacin is a broad-spectrum antibacterial 8-methoxy-fluoroquinolone. In order to evaluate the pharmacokinetic properties of moxifloxacin in mouse plasma and brain tissue, we developed a high-performance liquid chromatography (HPLC) method. This study was based on single-drug delivery, intravenously dosed in a central listeriosis murine model.

Rapid eradication of Listeria monocytogenes by moxifloxacin in a murine model of central nervous system listeriosis.

Listeriosis is a rare but life-threatening infection. A favorable outcome is greatly aided by early administration of antibiotics with rapid bactericidal activity against Listeria monocytogenes. Moxifloxacin, a new-generation fluoroquinolone with extended activity against gram-positive bacteria, has proved its effectiveness in vitro against intracellular reservoirs of bacteria.

Evaluation of pharmacokinetic interactions after oral administration of mycophenolate mofetil and valaciclovir or aciclovir to healthy subjects.

Objective: To investigate a potential pharmacokinetic interaction between mycophenolate mofetil (MMF) and aciclovir or valaciclovir.

Study Design And Participants: Fifteen healthy subjects were enrolled in a prospective, randomised, open-label, single-dose, cross-over study conducted at a single centre. Subjects received each of the following five oral treatments: (i) aciclovir 800 mg alone; (ii) valaciclovir 2 g alone; (iii) MMF 1 g alone; (iv) valaciclovir 2 g + MMF 1 g; and (v) aciclovir 800 mg + MMF 1 g.

Glucocorticoid pharmacokinetics and growth retardation in children with renal transplants.

Long-term glucocorticoid treatment contributes to the growth retardation in children after renal transplantation. We investigated whether determination of prednisone (PN) and prednisolone (PL) in plasma and PN, PL, and 6-beta-hydroxyprednisolone (betaOH-PL) in urine could help to predict growth. PN and PL pharmacokinetics were studied in 36 children, from 5 to 15 years of age, receiving daily (D) or alternate-day (AD) oral PN treatment.
