Nine eligible studies published between 2002 and 2008 were identified, eight of which are presented. The five in-vitro studies demonstrated that moxifloxacin and gatifloxacin are statistically more potent than levofloxacin against Gram-positive organisms and similar in potency in most cases of Gram-negative bacteria. In-vivo animal models testing moxifloxacin or gatifloxacin against levofloxacin 0.5% (no clinical trials testing the efficacy of levofloxacin 1.5% have yet been published) demonstrated that fourth-generation agents were superior to third-generation levofloxacin 0.5% for prophylaxis of Gram-positive bacteria-induced infections and were equal to, or better than, levofloxacin 0.5% for the treatment of Gram-negative infections.

This study was conducted to detect and analyse the presence of plasmid-mediated quinolone resistance (PMQR) determinants [qnr, aac(6')-Ib-cr and qepA] among Citrobacter freundii isolates from patients in Anhui province, PR China. During 2009-2010, 31 C. freundii strains were collected from various hospital units and patient specimens. Using PCR, qnr genes were detected in eight isolates, but aac(6')-Ib-cr and qepA genes were not found. The genes qnrA1, qnrB1, qnrB2, qnrB4, qnrB10 and qnrB24 were present in 6.5, 3.2, 6.5, 3.2, 3.2 and 3.2% of C. freundii isolates, respectively. A new subgene of qnrB variant (qnrB24) was found and identified for what we believe to be the first time. PFGE after XbaI digestion of genomic DNA indicated that qnr-positive strains were not clonally related. Conjugation experiments were conducted to determine whether the qnr-carrying plasmids were self-transferable, and plasmids of transconjugants were extracted and analysed. The qnr genes were transferred from three clinical isolates to their transconjugants. Two qnrA1 genes transferred quinolone resistance with a plasmid of ~11 kb, whilst the size of the plasmid carrying the qnrB4 gene was ~64 kb. The susceptibility of positive isolates and transconjugants was tested using an agar dilution method according to Clinical and Laboratory Standards Institute guidelines, and the MICs of ciprofloxacin and levofloxacin were determined using Etest strips. Most isolates with qnr genes were resistant to fluoroquinolones and other antimicrobial agents. The MICs of transconjugants showed reduced susceptibility to fluoroquinolones.

levaquin 500mg dosage

Extensive pharmacologic and clinical development of quinolone antimicrobial agents has resulted in improved antimicrobial activity, pharmacokinetic features, toxicity, and drug-drug interaction profiles. Nalidixic acid and other early quinolones had limited use due to poor pharmacokinetics, relatively narrow antimicrobial spectrum of activity, and frequent adverse effects. Beginning with the development of fluoroquinolones, such as norfloxacin and ciprofloxacin, in the 1980s, the agents assumed a greatly expanded clinical role because of their broad antimicrobial spectrum of action, improved pharmacokinetic properties, and more acceptable safety profile. Although the pharmacokinetics and efficacy of the drugs have improved significantly, a major area of continued emphasis is to further reduce the frequency and severity of adverse events and drug-drug interactions. Older agents such as ciprofloxacin and ofloxacin are still extensively prescribed, but the focus of this article is on the newer fluoroquinolones (levofloxacin and other drugs that have been approved or have been under investigation since approximately 1997).

As part of the SENTRY antimicrobial resistance surveillance program, a total of 1100 clinically significant respiratory tract isolates of Streptococcus pneumoniae were tested for susceptibility to six fluoroquinolone antimicrobial agents: ciprofloxacin, levofloxacin, gatifloxacin, grepafloxacin, sparfloxacin, and trovafloxacin. Isolates were obtained during the 5-month period, February to June, 1997 from 27 United States medical center laboratories and seven laboratories in Canadian health care institutions. All testing was performed in a single center. Of 1100 test strains, 3 (0.3%), all from different U.S. centers, were fluoroquinolone resistant. Among the remaining 1097 fluoroquinolone-susceptible isolates, the rank order of activity among the six agents tested in this study was grepafloxacin (modal MIC = 0.25 microgram/mL) = trovafloxacin (modal MIC = 0.25 microgram/mL) = sparfloxacin (0.25 microgram/mL) > gatifloxacin (0.5 microgram/mL) > levofloxacin (1 microgram/mL) = ciprofloxacin (1 microgram/mL). Fluoroquinolone resistance is currently uncommon among respiratory tract isolates of S. pneumoniae in North America, but there exist clear differences between the in vitro activities of different fluoroquinolones for this organism.

A sensitive fluorescence (FL) technique is proposed for the determination of levofloxacin (LVX). The method is based on the fact that the weak FL signal of the Tb(III)-LVX system is strongly enhanced in the presence of gold nanoparticles. Gold nanoparticles were prepared by the citrate reduction of HAuCl(4) and characterized by transmission electron microscopy (TEM). Levofloxacin and Tb(III) ion form a fluorescence complex in aqueous solution, and its maximum emission wavelength was found at 545 nm. Optimal conditions for the formation of the levofloxacin-Tb(III) complexes were studied. Levofloxacin was detected by measuring the FL intensity, which increases linearly with the concentration of LVX in the range 6.2 × 10(-10)-2.6 × 10(-8) mol/L. Recovery of the target analytes was > 96% with good quality parameters: linearity (r(2) > 0.996), limit of detection (LOD) and limit of quantification (LOQ) values 2.1 × 10(-10) mol/L and 7.2 × 10(-10) mol/L, and run-to-run and day-to-day precisions with relative standard deviations (RSDs) around 3%. Thus, the proposed method can be successfully applied to the routine determination of levofloxacin in pharmaceutical preparations.

Fluoroquinolone development from 1985 to the present was reviewed. Severe drug adverse events were noted for enoxacin, pefloxacin and fleroxacin, which were phototoxic. Temafloxacin was associated with severe hemolytic-uremic syndrome, lomefloxacin caused phototoxicity and central nervous system (CNS) effects, and sparfloxacin was associated with phototoxicity and QTc prolongation. Tosufloxacin caused severe thrombocytopenia and nephritis, and hepatotoxicity was reported for trovafloxacin. Grepafloxacin was withdrawn due to cardiovascular effects, and clinafloxacin was associated with phototoxicity and hypoglycaemia. The structure of the quinolones directly relates to both their activity and side-effect profiles. The relationship among specific substituents attached to the quinolone nucleus are clarified. The incidence of specific adverse events associated with individual fluoroquinolones was reviewed in a five-year post-marketing surveillance (PMS) study in Japan, in which a total adverse drug reaction (ADR) rate of 1.3% was found for levofloxacin, compared to total ADR rates of 3.3% for pazufloxacin, 3.6% for tosufloxacin, 4.5% for gatifloxacin and 5.4% for balofloxacin. Gastrointestinal effects were the most common adverse events for all fluoroquinolones. Levofloxacin had the lowest rate of CNS effects and skin adverse events among the agents listed.

To evaluate the resistance for major oral antimicrobial agents, mainly new quinolones, we carried out a drug susceptibility surveillance of 3,050 strains of 11 microbial species clinically isolated at 8 institutions such as general hospitals and examination centers in Hiroshima city. 10 antimicrobial agents were used: 3 new quinolone drugs, 5 beta-lactam drugs, minocycline and clarithromycin. Among Gram-positive bacteria, methicillin resistant Staphylococcus aureus (MRSA) and Enterococcus faecalis showed low susceptibility to the new quinolone drugs, while methicillin susceptible Staphylococcus aureus (MSSA) and Streptococcus pneumoniae were highly sensitive to these drugs. Among Gram-negative bacteria, Pseudomonas aeruginosa showed high resistance for the new quinolone drugs, but enteric bacteria and Haemophilus influenzae did not show marked resistance, maintaining almost good sensitivity to these drugs. To reduce the appearance of resistant bacteria, appropriate antimicrobial agents should be selected. Drug susceptibility surveillance in the community will be also important in the future.

Data on the tolerance and effectiveness of rifampicin-levofloxacin combination therapy (RLCT) in patients treated for prosthetic joint infections (PJIs) according to daily dosage are lacking. A review of the clinical data from patients treated with RLCT for PJIs in a French referent center for PJIs was conducted. A total of 154 patients (75 F/79 M), with a median age of 64.1 years and median body weight of 83.1 kg, were included. The median daily dosages of rifampicin and levofloxacin were, respectively, 1,200 mg (range 300-2,100) and 750 mg (range 500-1,500), corresponding to a mean daily dose per kg of, respectively, 16.2 ± 4.3 mg/kg and 10.1 ± 3.0 mg/kg. After a mean follow-up period of 55.6 ± 27.1 months (range 24-236), 127 patients (82.5 %) were in remission. Adverse events attributable to rifampicin and levofloxacin were reported in 48 (31.2 %) and 13 (8.4 %) patients (p < 0.001), respectively. Patients who experienced rifampicin-related adverse events had been given higher rifampicin daily doses than the other patients (p = 0.04). The rifampicin daily dosage did not influence patient outcome and nor did the levofloxacin daily dosage on both tolerance and patient outcome. Our results suggest that adjusting rifampicin daily doses to the patient total body weight when combined with levofloxacin for the treatment of PJIs is associated with a poor tolerance. High daily doses of rifampicin (>600 mg) and levofloxacin (750 mg) do not improve patient outcome when compared to lower daily doses in this setting.

The antimicrobial susceptibility of 339 isolates from the otorhinolaryngological infections at the otorhinolaryngological departments at 27 universities in buy levaquin Japan, as well as their 108 affiliated hospitals and practitioners during January 2007 to June 2007 was determined to garenoxacin (GRNX), levofloxacin, moxifloxacin, azithromycin, cefditoren, and cefcapene applicable for otorhinolaryngological infections. The in vitro activities of these drugs against the isolates were compared. The quinolones including GRNX were potently active against Streptococcus pneumoniae including penicillin-intermediate and -resistant strains (PISP and PRSP), Streptococcus pyogenes and methicillin-susceptible Staphylococcus aureus, except for MRSA, a major causative pathogens for otorhinolaryngological infection. When MIC ranges, MIC50, MIC80 and MIC90 of three quinolones were compared, it was considered that GRNX was the most active of them. GRNX was potently active against Haemophilus influenzae and Moraxella catarrhalis same as that of other quinolones tested. In conclusion, GRNX exhibits a potently active against fresh isolates from otorhinolaryngological infections, and has an effective potential in the treatment of otorhinolaryngological infections.

There are a number of potential drugs for the treatment of cystic fibrosis (CF) currently undergoing clinical studies. A number of antibacterials formulated for delivery by inhalation are at various stages of buy levaquin study; these include dry-powder inhaler versions of colistin, tobramycin and ciprofloxacin, and formulations of azteonam, amikacin, levofloxacin, ciprofloxacin and fosfomycin/tobramycin for nebulization. Clinical trials of anti-inflammatory agents, including glutathione, phosphodiesterase-5 inhibitors such as sildenafil, oral acetylcysteine, simvastatin, methotrexate, docosahexaenoic acid, hydroxychloroquine, pioglitazone and alpha1-antitrypsin, are ongoing. Ion channel modulating agents, such as lancovutide (Moli1901, duramycin) and denufosol, which activate alternate (non-CF transmembrane regulator [CFTR]) chloride channels, and GS 9411, a sodium channel antagonist, are now at the stages of clinical study and if successful, will offer a new category of therapeutic agent for the treatment of CF. Correction of the underlying gene effect, either by agents that help to correct the dysfunctional CFTR, such as ataluren, VX-770 and VX-809, or by gene transfer (gene therapy), is a particularly exciting prospect as a new therapy for CF and clinical studies are ongoing. This article reviews the exciting potential drug treatments for CF currently being evaluated in clinical studies, and also highlights some of the challenges faced by research and clinical teams in assessing the efficacy of potential new therapies for CF.

Resistant clones/phenotypes are putting into question the activity of commonly used beta-lactams, thus prompting the need for alternative options. A 500 mg levofloxacin vs. azithromycin once daily pharmacodynamic simulation was performed against 10(8) cfu/ml of four Streptococcus pneumoniae strains (exhibiting higher amoxicillin than penicillin MIC) and four Haemophilus influenzae strains: beta-lactamase producing, BLNAR (beta-lactamase-negative ampicillin-resistant) and BLPACR (beta-lactamase-positive amoxicillin/clavulanate-resistant). High levofloxacin AUC/MIC values for H. influenzae, and values of 50-100 for S. pneumoniae produced a >5 log(10) reduction at 24h for all strains. Azithromycin AUC/MIC values of approximately 10 were needed to obtain a 2-3 log(10) reduction of S. pneumoniae initial inocula, but lower AUC/MIC values (of approximately 6) obtained > or =3 log(10) reduction against all strains of H. influenzae. While in vitro simulated serum concentrations of levofloxacin were bactericidal at the end of the dosing interval against all S. pneumoniae strains and azithromycin against the susceptible ones, both buy levaquin antimicrobials achieved this endpoint against the BLNAR and BLPACR strains.

The objective of this study was to determine: (i) the prevalence of resistance in current clinical isolates of Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Moraxella catarrhalis and Klebsiella pneumoniae; (ii) the prevalence of production of extended-spectrum beta-lactamases (ESBLs) and methicillin resistance in S. aureus; and (iii) regional differences in the prevalence of ESBL production and clonality of K. pneumoniae isolates. Pathogens causing respiratory tract infections in hospitalised patients were prospectively collected from all over Germany. Drugs tested by Etest included moxifloxacin, levofloxacin, amoxicillin/clavulanic acid, cefuroxime, clarithromycin and penicillin G. ESBL production by K. pneumoniae was determined using cefotaxime/ceftazidime +/- clavulanic acid. Deutsches Institut für Normung (German Institute for Standardisation)/European Committee on Antimicrobial Susceptibility Testing (DIN/EUCAST) breakpoints were used where applicable. Overall, 1859 pathogens were analysed. For all species tested the fluoroquinolones achieved the highest overall susceptibility rate (92.8%) compared with clarithromycin (60.5%), amoxicillin/clavulanic acid (85.7%) and cefuroxime (89.6%). From 438 K. pneumoniae isolates, 13.0% produced an ESBL. Neurontin Mg The ESBL prevalence was 38.8% in Eastern Germany with a trend towards clonality in some centres, but ranged from 4.7% to 7.1% in Southern, Northern and Western Germany. Among the methicillin-susceptible S. aureus isolates, 10.1% were moxifloxacin- and levofloxacin-resistant. Of the S. pneumoniae isolates, 99.3% were moxifloxacin- and levofloxacin-susceptible, 93.9% were penicillin G-susceptible and 85.7% were clarithromycin-susceptible. With a MIC90 value (minimal inhibitory concentration for 90% of the isolates) of 0.19 mg/L, moxifloxacin was more potent than levofloxacin (MIC90 = 1 mg/L) against S. pneumoniae. Haemophilus influenzae and M. catarrhalis were almost 100% susceptible to the quinolones; 100% of the M. catarrhalis but only 4.5% of the H. influenzae strains were clarithromycin-susceptible. Moxifloxacin was the most active agent amongst the drugs tested, in particular against Gram-positive pathogens.

Dalbavancin is a long acting, bactericidal lipoglycopeptide. Its in vitro activity was compared with that of vancomycin, daptomycin, linezolid, trimethoprim/sulfamethoxazole (TMP/SMX) and levofloxacin against 241 Gram-positive organisms isolated from cancer patients. The rank order of potency for the glycopeptides based on MIC90 (μg ml(-1)), that is, the concentration of antimicrobial agent required to inhibit 90% of isolates tested was dalbavancin (0.12 μg ml(-1))>daptomycin (1.0 μg ml(-1))>vancomycin (2.0 μg ml(-1)) for coagulase-negative staphylococci and Staphylococcus aureus isolates (including methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) strains). Dalbavancin had potent activity against staphylococcal isolates with vancomycin MICs⩾1.0 μg ml(-1). TMP/SMX also had potent activity against staphylococci including methicillin-resistant strains, whereas levofloxacin had moderate to poor anti-staphylococcal activity. Dalbavancin also exhibited more potent activity than vancomycin and daptomycin against Bacillus spp., Corynebacterium spp., Micrococcus spp. and various streptococci (including Streptococcus pneumoniae, viridans group streptococci (VGS), Nizoral Pills beta-hemolytic streptococci and gamma-hemolytic streptococci). MBC determinations showed that dalbavancin had potent bactericidal activity against MRSA with no tolerance being detected. These data suggest that dalbavancin may be considered as an alternative to vancomycin, especially in institutions wherein a substantial proportion of infections are caused by organisms with vancomycin MICs⩾1.0 μg ml(-1).

The initial bactericidal activity of quinolones against Streptococcus pneumoniae at the concentration equivalent to their respective peak serum concentration (C(max)) and free drug fraction of C(max) (fC(max)) were investigated. The bactericidal activity of sitafloxacin (STFX), levofloxacin (LVFX), moxifloxacin (MFLX), and garenoxacin (GRNX) were compared by determining the actual killing of bacteria at C(max) and fC(max) for 1 and 2 hours based on the Japanese maximum dose per administration (100, 500, 400 Buspar Usual Dosage , and 400 mg, respectively). Against 4 quinolone-susceptible clinical isolates (wild-type), STFX with C(max) and fC(max) exhibited the most rapid bactericidal activity resulting in an average reduction of > or = 3.0 log10 colony forming units (CFU)/ mL in 1 hour. STFX with C(max) and fC(max) also showed the most rapid and potent bactericidal activity against 9 clinical isolates with single par (C/E) mutation, resulting in > or = 3.0 log10 CFU/mL average reduction in viable cells in 1 hour. STFX showed a statistically significant advantage in initial bactericidal activity over other quinolones for single mutants (P < 0.001). The propensity that the difference in the initial bactericidal activity between STFX and other quinolones was higher in single mutants than wild-type strains, was confirmed using S. pneumoniae ATCC49619 (wild-type) and its laboratory single parC mutant. As a result, STFX showed a similar rapid and potent initial bactericidal activity against both strains, while initial bactericidal activity for other quinolones was significantly reduced in the single mutant (P < 0.05). In conclusion, STFX has the most rapid and potent initial bactericidal activity against wild-type and single mutants of S. pneumoniae and its bactericidal activity is not affected by the presence of a single par mutation compared to LVFX, MFLX, and GRNX.

The chronic course and evolution of chronic obstructive pulmonary disease (COPD) is often characterized by periods of exacerbation of symptoms, which have a negative impact on the quality of life of patients, as well as on the evolution of COPD, and represent a significant cause of medical intervention and hospitalization. Very few data are available on the efficacy of rescue antibiotics in patients with acute exacerbation of COPD (AECOPD) unresponsive to previous treatment. The aim of this study was to evaluate the efficacy of two fluoroquinolones in AECOPD previously treated without success. The FADOI-FLOR study is a randomized, single-blind, non-inferiority comparison between levofloxacin and prulifloxacin. Primary end-point was "therapeutic success" at Day 10 of treatment, defined as disappearance of signs/symptoms or decrease of at least three points of a global score of symptomatology (maximum score = 15). 258 patients were enrolled (128 levofloxacin and 130 prulifloxacin), in 25 centers. A very high proportion of patients in the two groups had therapeutic success at Day-10 (levofloxacin 93.0% vs prulifloxacin 96.7%, population intention-to-treat; 94.6% vs 99.1%, population per-protocol). Earlier therapeutic success (within 7 days) Urispas Capsule was achieved in 32.0% and 36.2% of patients receiving levofloxacin or prulifloxacin, respectively. At 3-month follow-up, re-exacerbations occurred in 17.8% of patients treated with levofloxacin and 14.2% of those receiving prulifloxacin (p = 0.44). In conclusion, fluoroquinolones are very effective in the treatment of AECOPD resistant to other antibiotics.

The aim of this study was to examine mutations in the quinolone-resistance-determining region (QRDR) of gyrA and parC genes in Pseudomonas aeruginosa isolates. A total of 100 clinical P. aeruginosa isolates were collected from different university-affiliated hospitals in Tabriz, Iran. Minimum inhibitory concentrations (MICs) of ciprofloxacin and levofloxacin were evaluated by agar dilution assay. DNA sequences of the QRDR of gyrA and parC were determined by the dideoxy chain termination method. Of the total 100 isolates, 64 were resistant to ciprofloxacin. No amino acid alterations were detected in gyrA or parC genes of the ciprofloxacin susceptible or ciprofloxacin intermediate isolates. Thr-83 → Ile substitution in gyrA was found in all 64 ciprofloxacin resistant isolates. Forty-four (68.75%) of them had additional substitution in parC. A correlation was found between the number of the amino acid alterations in the QRDR of gyrA and parC and the level of ciprofloxacin and levofloxacin resistance of the P. aeruginosa isolates. Ala-88 → Pro alteration in Tegretol High Dose parC was generally found in high level ciprofloxacin resistant isolates, which were suggested to be responsible for fluoroquinolone resistance. These findings showed that in P. aeruginosa, gyrA was the primary target for fluoroquinolone and additional mutation in parC led to highly resistant isolates.
