Objective To assess the effectiveness and safety of prulifloxacin in the treatment of urinary tract infection. Methods The double-blind, double dummy and randomized controlled method was adopted. One hundred and forty-four patients were randomized to the treatment group (prulifloxacin , 4 tablets, bid) and the control group (levofloxacin, 4 tablets, bid). The randomization code was produced by computer. The treatment duration for both groups was from 7 to 10 days. Results Data were analyzed on the basis of full analysis sets (FAS) and per-protocol (PP) analysis. The total improvement rates of the trial and control groups were 85.07% and 88.52% respectively by FAS analysis, and 90.48% and 91.53% respectively by PP analysis. There was no significant difference between the two groups in improvement rates (Pgt;0.05). Bacterial negative rates in the trial and control groups were 93.75% and 93.88% respectively by FAS analysis and 97.83% and 97.87% respectively by PP analysis. The results showed no statistical significance difference between the two groups in bacterial negative rates (Pgt;0.05). The adverse events in the prulifloxacin and levofloxacin groups were 2.80% and 5.60% respectively. Conclusion Prulifloxacin has the same clinical effectiveness as levofloxacin with a few toxic adverse effects in the treatment of urinary tract infection.

Methods From January 2004 to December 2009, the clinical data from 54 cases of SBP after cirrhosis were analyzed. The patients underwent the treatment of cefoperazone sulbactam combined with levofloxacin. The therapeutic effect was observed. Results The main clinical manifestations were fever and abdominal pain, and about half of the patients had the typical peritoneal irritation. Only a few patients had elevated peripheral white blood cells (WBC). The WBC count, abdominal effusion polymorphonuclearcyte count and bacteria cultivation were the indexes of diagnosis of SBP. Conclusion The clinical features of post-hepatitis cirrhosis complicated with SBP are not typical. The main pathogenic bacteria is G- bacilli. In the early diagnosis and treatment, cefoperazone sulbactam combined with levofloxacin is effective.
This research was aimed to find the skin irritation and burns treatment effect of wound dressing with microspheres containing levofloxacin. We used reference GB/T16886.10-2005 to evaluate the dressing skin irritation. We prepared rabbit models divided into three groups. The control group was rapped with Vaseline gauze bandage, while the positive control group was rapped with the wounds of nano-silver paste bandage. The experimental sample group was rapped with wound dressing with microspheres containing levofloxacin. We measured the wound without healing area and the hydroxyproline content at the ends of 3 d, 6 d, 9 d, 14 d, 21 d, 28 d. and meanwhile performed histopathological examination. The experimental results showed that the dressing primary irritation index was 0. The nonhealing wound area of theexperimental sample group and positive control group at the ends of 6 d, 9 d, 14 d, 21 d were less than that of the control group (P<0.05). The nonhealing wound area of the experimental sample group at the ends of 9 d and 14 d was significantly lower than that of the positive control group (P<0.05). The hydroxyproline content of the experimental sample group at the ends of 6 d, 9 d and 14 d was significantly higher than that of the positive control group and blank control group (P<0.05). The pathology observed of the experimental sample group at 21 d were the earliest appendages. The wound dressing with microspheres containing levofloxacin has minimal skin irritation, effectively promote wound healing of burn.
Objective To access the effectiveness and safety of levofloxacin in controlling multidrug resistant tuberculosis (MDR-TB). Methods The electronic searches in databases of PubMed, EMbase, The Cochrane Library, CNKI, CBM and VIP, handsearches and other searches were conducted from the date of their establishment to April 2011 for collecting randomized controlled trials (RCTs) on levofloxacin treating MDR-TB. Two researchers independently screened the literature according to the inclusive and exclusive criteria, extracted the data, assessed the quality of the included studies by adopting the Jadad scale, and performed Meta-analysis by using RevMan 5.0 software. Results A total of 31 RCTs involving 2836 cases were included. The results of meta-analysis showed: a) Compared with the placebo group, levofloxacin could increase the sputum negative conversion rate after 3-month taking and at the end of the treatment period; b) Compared with the ofloxacin group, levofloxacin could increase the sputum negative conversion rate after 3 months and at the end of the treatment period; c) levofloxacin replacing either ethambutol or streptomycin could increase the sputum negative conversion rate after 3 months and at the end of the treatment period; d) Compared with the levofloxacin group, gatifloxacin and moxifloxacin could increase the sputum negative conversion rate after 3 months and at the end of the treatment period; e) There was no significant difference in the adverse reaction rate between each of the medication regimens (P=0.19). Conclusion Levofloxacin is more effective for MDR-TB than ofloxacin, ethambutol and streptomycin, but it is inferior to gatifloxacin or moxifloxacin. Its adverse reaction rate is equivalent to other medicines’.
Objective To assess the effectiveness and safety of moxifloxacin versus levofloxacin for the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods Such databases as PubMed, EMbase, The Cochrane Library, CBM, CNKI and VIP were electronically searched, and the relevant conference proceedings were also hand-searched. The search time was up to July, 2011. Randomized controlled trials (RCTs) on moxifloxacin versus levofloxacin for AECOPD were included. Literature was screened according to inclusive and exclusive criteria, data were extracted, quality was assessed, and then meta-analysis was performed using RevMan 5.0. Results A total of 6 RCTs involving 482 patients with AECOPD were included. The results of meta-analysis showed that moxifloxacin group was significantly superior to levofloxacin group in the effective rate (OR=3.15, 95%CI 1.80 to 5.49, Plt;0.000 1). The bacterial clearance rate in moxifloxacin group was also higher than that in the levofloxacin group (OR=2.79, 95%CI 1.30 to 5.97, P=0.008). In addition, adverse effects of moxifloxacin group were less than levofloxacin (OR=0.48, 95%CI 0.24 to 0.98, P=0.04). Conclusion Based on current studies, moxifloxacin is superior to levofloxacin in improving effective rate and bacterial clearance rate, and in lowering side effects when treating AECOPD. Hence it is considerable to use moxifloxacin instead of levofloxacin in the treatment of AECOPD if necessary. Due to the limitation of both quantity and quality of included studies, this conclusion should be further confirmed with more high quality and large sample studies.
Objective To evaluate the clinical efficacy and safety of pazufloxacin for the treatment of moderate and severe acute bacterial respiratory infections.Methods A multicenter randomized controlled trial was conducted to compare the efficacy and safety of pazufloxacin versus levofloxacin. Patients in the pazufloxacin group were treated with pazufloxacin (500 mg twice daily for 7 to 10 days), and patients in the levofloxacin group were treated with levofloxacin (300 mg twice daily for 7 to 10 days). Results A total of 134 patients were enrolled in the study, 68 cases in pazufloxacin group and 66 cases in levofloxacin group were assessable for clinical efficacy by full analysis set(FAS). At the end of the treatment, in FAS analysis the total cure rates and effective rates were 52.9% and 86.7% in pazufloxacin group, 57.6% and 87.9% in levofloxacin group, in PPS analysis the total cure rats and effective rates were 57.1% and 93.7% in pazufloxacin group respectively, 61.3% and 93.6% in levofloxacin group. The bacterial clearance rates were 92.5% and 94.3% respectively. There were no statistically significant differences between the two groups. Adverse reactions were observed in 16.2% of patients in the pazufloxacin group and in 16.7% of patients in the levofloxacin group. These reactions were mainly local stimulation, nausea and diarrhea. No serious adverse event was reported in either group. Conclusion Pazufloxacin is as effective and safe as levofloxacin for the treatment of moderate to severe acute respiratory infections.
