PURPOSE To examine the in vitro resistance to ofloxacin of preoperative bacterial isolates from the conjunctival sac of Japanese patients. METHODS The database of bacterial flora cultured preoperatively from the conjunctival sac of 1455 Japanese patients (1455 eyes) between 1995 and 1999 was reviewed retrospectively. RESULTS The incidence of resistance of isolates to ofloxacin in vitro incr...

The efficacy and tolerance of ofloxacin and doxycycline were compared in patients with lower respiratory tract infections. Doses used were 200 or 400mg twice daily for ofloxacin and 100mg twice daily for doxycycline. Of 230 patients treated, 219 could be assessed for effectiveness. 88 patients were treated for exacerbations of chronic bronchitis and 131 for pneumonia. Clinical cure was achieved...

A patient accidentally received approximately 3 g of ofloxacin intravenously. She experienced only moderately severe central nervous system symptoms, which resolved within 9 h. The peak serum ofloxacin level was 39.3 micrograms/ml, approximately seven times the usual peak level. Ofloxacin may possess a considerable safety margin in humans.

For the simultaneous determination of Nitazoxanide and Ofloxacin in tablet dosage form, a simple reverse phase liquid chromatographic method was developed validated. A mobile containing acetonitrile, methanol, 0.4 M citric acid (60:30:10, v/v/v) used for separation. Thermo C18 (4.6mm*250 mm, 5 ) column used, with flow rate 1 mL/min UV detection at 300 nm. ofloxacin had retention times 3.071 12....

Background: Pathogenic micro-organisms are the most commonly involved etiologic agents in causing external ocular diseases. Conjunctiva, lid and cornea are the most commonly affected parts of the eye. Ofloxacin is exceptionally potent against a wide range of Gram-positive and Gram-negative bacteria and obligate anaerobes. It is also reported to be effective against ocular pathogens. The action ...

Aims—To assess the subretinal fluid (SRF) levels of ofloxacin following topical, oral or combined administration. Methods—31 patients undergoing conventional retinal reattachment surgery were randomly assigned to three groups. Nine patients received topical ofloxacin, 11 patients received oral ofloxacin, and the other 11 patients received combined administration. Collected SRF samples were anal...

Background Ofloxacin is a second-generation fluoroquinolone that frequently has been prescribed against various bacterial infections. Serious hypersensitivity reactions will increase with high worldwide consumption. There have been few case reports of ofloxacin induced anaphylaxis and its pathogenic mechanism is not well understood. In this study, we investigated pathogenic mechanisms in a 20-y...

The mechanism of action of the quinolone analogs ofloxacin and S-25930, which are unusual because of the presence of a third ring with an asymmetric carbon, was studied. Drug-resistant strains of Escherichia coli were selected by serial passage in the presence of ofloxacin, and a mutation was mapped near the gyrA gene of DNA gyrase. DNA gyrase containing the A subunit purified from this strain ...

A novel, rapid and sensitive analytical method is described for determination of ofloxacin and levofloxacin by enhanced chemiluminescence (CL) with flow-injection sampling. The method is based on the CL reaction of the Ce(IV)-Na2S2O4-ofloxacin/levofloxacin-H2SO2 system. The enhanced CL mechanism was developed and the optimum conditions for CL emission were investigated. The CL intensity was cor...
