Gemifloxacin is a new quinolone and, like moxifloxacin, trovafloxacin, grepafloxacin and clinafloxacin, is more potent in vitro than ciprofloxacin or ofloxacin against Gram-positive aerobes. Gemifloxacin was the most potent of the quinolones tested against streptococci and most ciprofloxacin-resistant pneumococci were susceptible to gemifloxacin. Gemifloxacin, like moxifloxacin, trovafloxacin, ...
Although gemifloxacin has low in vitro activity against Mycobacterium tuberculosis, the effect of gemifloxacin on the delay of tuberculosis (TB) treatment has not been validated in a clinical setting. The study group included patients with culture-confirmed pulmonary TB who initially received gemifloxacin for suspected community-acquired pneumonia (CAP). Two control groups contained patients tr...
OBJECTIVES The rapid emergence of methicillin-resistant Staphylococcus aureus from the community (CA-MRSA) presents difficulties in making treatment choices. We evaluated whether combining another orally available agent commonly used to treat CA-MRSA with gemifloxacin would enhance gemifloxacin activity against CA-MRSA. METHODS Fifty strains of SCCmec IV, agr group 1, Panton-Valentine leucoci...
The in vivo efficacy of the novel quinolone gemifloxacin (SB-265805) was examined in a rat respiratory tract infection (RTI) model against four strains of Streptococcus pneumoniae and two strains of Haemophilus influenzae with varying susceptibilities to standard antimicrobial agents. Animals were infected intrabronchially to produce pneumonia and therapy with oral gemifloxacin, amoxycillin-cla...
Probenecid interacts with transport processes of drugs at several sites in the body. For most quinolones, renal clearance is reduced by concomitant administration of probenecid. The interaction between gemifloxacin and probenecid has not yet been studied. We studied the extent, time course, site(s), and mechanism of this interaction. Seventeen healthy volunteers participated in a randomized, tw...
The intracellular penetration and activity of gemifloxacin in human polymorphonuclear leukocytes (PMN) were evaluated. Gemifloxacin reached intracellular concentrations eight times higher than extracellular concentrations. The uptake was rapid, reversible, and nonsaturable and was affected by environmental temperature, cell viability, and membrane stimuli. At therapeutic extracellular concentra...
Free gemifloxacin concentrations in the interstitial space fluid of skeletal muscle and subcutaneous adipose tissue were measured by means of in vivo microdialysis to characterize the ability of gemifloxacin to penetrate human soft tissues. Twelve healthy volunteers received a single oral dose of 320 mg of gemifloxacin. The mean areas under the concentration-time curves from 0 to 10 h (AUC(0-10...
The cost-effectiveness of treatment with oral gemifloxacin versus oral clarithromycin for acute exacerbations of chronic bronchitis (AECB) was evaluated. Economic outcomes were assessed for the Gemifloxacin Long-term Outcomes in Bronchitis Exacerbations study. This prospective double-blind, controlled, health outcomes study compared health, economic, and clinical outcomes after randomized treat...
Gemifloxacin mesylate is a synthetic fluoroquinolone derived antimicrobial agent. Two metal complexes of gemifloxacin were synthesized viz. gemifloxacin-Fe and gemifloxacin-Zn. The formed characterized by using TLC, TGA FT-IR spectra analyses. then evaluated for activity. newly two assessed against nine bacterial one fungal strain, where (30 µg/disc) was used as reference standard. new showed b...
The newest generation of fluoroquinolones have proven efficacy against bacterial organisms associated with acute exacerbation of chronic bronchitis (AECB). Gemifloxacin, as one of the quinolones in this class, exhibits many of the pharmacokinetic and pharmacodynamic characteristics of the class with a few notable differences. Against Streptococccus pneumoniae it has a lower minimal inhibitory c...
