Grepafloxacin and levofloxacin transport by Caco-2 cell monolayers was examined to characterize the intestinal behavior of these quinolones. The levels of transcellular transport of [(14)C]grepafloxacin and [(14)C]levofloxacin from the basolateral to the apical side were greater than those in the opposite direction. The unidirectional transport was inhibited by the presence of excess unlabeled ...
BACKGROUND We have evaluated the therapeutic efficacy of AIGIV when given in combination with levofloxacin and the effective window of treatment to assess the added benefit provided by AIGIV over standard antibiotic treatment alone in a New Zealand white rabbit model of inhalational anthrax. METHODS Rabbits were exposed to lethal dose of aerosolized spores of Bacillus anthracis (Ames strain) ...
An in-vitro pharmacokinetic model was used to compare the pharmacodynamics of levofloxacin and ciprofloxacin against four penicillin-susceptible and four penicillin-resistant Streptococcus pneumoniae. Logarithmic-phase cultures were exposed to the peak concentrations of levofloxacin or ciprofloxacin observed in human serum after 500 mg and 750 mg oral doses, human elimination pharmacokinetics w...
An attempt was made to develop a single, rapid, specific, and sensitive gradient reversed-phase ultra-performance liquid chromatographic method for quantitative analysis of levofloxacin. The single method thus developed is applied for the quantification of levofloxacin both in aqueous humour as well as pharmaceutical dosage forms (i.e., tablets and eye drops). The newly developed method is appl...
BACKGROUND Dystonia is a hyperkinetic movement disorder related to dysfunction of inhibitory basal ganglia and cortical circuits. GABA is the major inhibitory neurotransmitter in the central nervous system. Quinolones can rarely produce serious neurologic effects, which have been attributed to impaired inhibition through GABA antagonism. We report a case of reversible craniocervical dystonia as...
Clinical antimicrobial susceptibility breakpoints are used to predict the clinical outcome of antimicrobial treatment. In contrast, microbiologic breakpoints are used to identify isolates that may be categorized as susceptible when applying clinical breakpoints but harbor resistance mechanisms that result in their reduced susceptibility to the agent being tested. Currently, the National Committ...
Objective: The study aimed at obtaining and characterizing levofloxacin-loaded, poly(ε-caprolactone) electrospun nanofiber formulations to be used as antibacterial wound dressings. Methods: Drug-loaded nanofibers were obtained by the electrospinning process and their morphology was determined using scanning electron microscopy. Structural analysis of the prepared nanofibers was carried out usin...
Five hundred ninety patients were enrolled in a prospective, multicenter, randomized trial comparing the efficacy and safety of 7 to 14 days of levofloxacin treatment with that of ceftriaxone and/or cefuroxime axetil in the management of community-acquired pneumonia in adults. Patients received either intravenous and/or oral levofloxacin (500 mg once daily) or the comparative agents, parenteral...
BACKGROUND The role that inflammation plays in the development of prostate cancer is unknown. We aimed to assess whether an anti-inflammatory drug or antibiotic, or both, could prevent prostate cancer occurrence and delay transformation to castration-resistant prostate cancer. METHODS This open-label, randomised, controlled trial recruited participants who had undergone a prostate biopsy in W...
