BACKGROUND AND OBJECTIVE Moxifloxacin 400 mg is a widely used positive control in thorough QT (TQT) studies, but its QT-prolonging effects in Korean subjects have not been studied. The present study was conducted to collect pilot data in Korean subjects after moxifloxacin administration to evaluate the adequacy of moxifloxacin as a positive control. METHODS Thirty-eight, healthy, Korean, male...

BACKGROUND The long duration of the current tuberculosis (TB) treatment is demanding and warrants the development of new drugs. Moxifloxacin shows promising results and may be combined with rifampicin to shorten the duration of TB treatment. Rifampicin induces the phase II metabolic enzymes that are involved in the biotransformation of moxifloxacin. Therefore, the interaction between rifampicin...

Lowering the gut exposure to antibiotics during treatments can prevent microbiota disruption. We evaluated the effects of an activated charcoal-based adsorbent, DAV131A, on the fecal free moxifloxacin concentration and mortality in a hamster model of moxifloxacin-induced Clostridium difficile infection. A total of 215 hamsters receiving moxifloxacin subcutaneously (day 1 [D1] to D5) were orally...

Belgian data on the treatment of respiratory tract infections with antibiotics in ambulatory care showed that fluoroquinolone use remains well controlled. Belgian guidelines have recommended moxifloxacin for CAP outpatients with comorbid conditions or outpatients in whom infection with atypical pathogens needs to be considered. Moxifloxacin is recommended in case of IgE-mediated ß-lactam allerg...

PURPOSE To report endophthalmitis rates after cataract surgery and the incidence of complications after intracameral moxifloxacin injection. SETTING Nineteen clinics in Japanese institutions. DESIGN Retrospective survey cohort study. METHODS The number of surgeries and endophthalmitis cases in the past 4 years before and after the introduction of intracameral moxifloxacin was evaluated. T...

Moxifloxacin penetrates well into oromaxillary tissue and covers the causative pathogens that show an increasing resistance to standard antibiotics. Clinical reports suggest that moxifloxacin may be effective for the treatment of odontogenic infections that can lead to serious complications. The objective of this prospective, randomized, double-blind, multicenter study was to compare the effica...

The absence of the Holliday-junction Ruv resolvase of Mycobacterium smegmatis increased the bacteriostatic and bactericidal activities of the fluoroquinolone moxifloxacin, an important antituberculosis agent. The treatment of ruvAB-deficient cells with thiourea and 2,2'-bipyridyl lowered moxifloxacin lethality to wild-type levels, indicating that the absence of ruvAB stimulates a lethal pathway...

PURPOSE Postsurgical endophthalmitis is a sight-threatening problem. We introduce a simple approach by using a single application of thermoresponsive controlled-release microspheres, loaded with moxifloxacin, to prevent bacterial endophthalmitis in a rabbit endophthalmitis prevention model. METHODS We separated 24 rabbits into 3 treatment groups in which topical drop treatment was placed onto...

INTRODUCTION The QT interval prolongation is an adverse effect associated with moxifloxacin. This adverse effect can lead to potentially life-threatening arrhythmias such as Torsades de pointes. We describe a case of severe QT interval prolongation associated with moxifloxacin which may cause the development of Torsades de pointes. There have been no reported case of severe corrected QT interva...

A single 400 mg dose of moxifloxacin has been the standard positive control for thorough QT (TQT) studies. However, it is not clearly known whether a 400 mg dose is also applicable to TQT studies in Asian subjects, including Koreans. Thus, we aimed to develop a pharmacokinetic (PK)-pharmacodynamic (PD) model for moxifloxacin, to evaluate the time course of its effect on QT intervals in Koreans....
