A new nanocarrier is developed for the passage of gatifloxacin through the blood-brain barrier to treat central nervous system tuberculosis. Gatifloxacin nanoparticles were prepared by nanoprecipitation using poly(lactic-co-glycolic acid) (PLGA) 502 and polysorbate 80 or Labrafil as surface modifiers. The evaluation of in vivo blood-brain barrier transport was carried out in male Wistar rats us...
Biofilms can be defined as communities of microorganisms attached to a surface. Those bacterial biofilms cause serious problems, such as antibiotic resistance and medical device-related infections. Nontypeable Haemophilus influenzae (NTHi) is an important pathogen in respiratory infections, as it forms biofilms both in vitro and in vivo such as human middle ear. Recent reports indicate that oti...
This study developed a method for analysis of nineteen quinolone and fluoroquinolone antibiotics (FQs) in sludge samples, and investigated the occurrence and fate of the FQs in a municipal sewage treatment plant (STP) with anaerobic, anoxic, and aerobic treatment processes. Eleven compounds, including pipemidic acid, fleroxacin, ofloxacin, norfloxacin, ciprofloxacin, enrofloxacin, lomefloxacin,...
A case of Gatifloxacin-induced severe and recurrent hypoglycemia in 62-year-old type 2 diabetic patient is presented. Possible mechanisms responsible for hypoglycemia are discussed and the literature on the subject is reviewed.
Fluoroquinolones (FQs) are extensively used in bacterial keratitis and other intraocular infections. Since eye is constantly exposed to light, incidence of ocular phototoxicity due to commonly used FQs is of great interest for their safe use. Phototoxicity of commonly used FQs (ciprofloxacin, lomefloxacin, pefloxacin, ofloxacin, sparfloxacin and gatifloxacin), has been evaluated by using HET-CA...
In recent years, the level of resistance of S. pneumoniae to beta-lactam and/or macrolides has increased around the world including some countries in South America. Because of this resistance, it is necessary to test the therapeutic alternatives for treating this pathogen, including the newer quinolones. This study was carried out in order to compare the in vitro activity of fluoroquinolones ga...
Drug-plasma protein binding is one of the many factors which influence bioavailability of a drug. Efficacy, distribution and elimination of a drug can be affected by the reversible binding of the drug to plasma proteins, such as albumin and acid glycoprotein. The purpose of the study was to study the relative in vitro protein binding characteristics of various drugs like diclofenac sodium, pant...
We made an open label, multicenter, non-comparative study to assess the efficacy and safety of oral gatifloxacin, 400 mg PO given once-daily during 7 to 14 days for the treatment of adult outpatients with community-acquired pneumonia at five Brazilian medical facilities. Among the 86 subjects available for clinical evaluation, 84 (98%) were cured. The bacteriological eradication and presumed er...
The interplay between bacterial antimicrobial susceptibility, phylogenetics and patient outcome is poorly understood. During a typhoid clinical treatment trial in Nepal, we observed several treatment failures and isolated highly fluoroquinolone-resistant Salmonella Typhi (S. Typhi). Seventy-eight S. Typhi isolates were genome sequenced and clinical observations, treatment failures and fever cle...
