Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/25340832
Curator's Comment: description was created based on several sources, including https://www.drugs.com/history/ozenoxacin.html | https://clinicaltrials.gov/ct2/show/NCT02090764 | https://www.ncbi.nlm.nih.gov/pubmed/11864945

Ozenoxacin is an experimental quinolone antibiotic being developed for the treatment of impetigo and other dermatological bacterial infections. Ozenoxacin is active against some bacteria that have developed resistance to currently used quinolone and fluoroquinolone antibiotics. In two phase 3 studies, Ozenoxacin cream, 1%, applied topically twice daily for 5 days vs. placebo, demonstrated superiority on both clinical and bacteriological endpoints, according to the release. Superior bacteriological cure of Ozenoxacin compared to placebo was demonstrated as early as day 4. In both adults and a pediatric population aged 2 months and older, Ozenoxacin treatment was reported to be safe and well tolerated.

In Vivo Use Guide

1% cream was applied topically on affected area of 1–100 cm^2 twice dally for 5 days

Route of Administration: Topical

In Vitro Use Guide

In vitro development of resistance was carried out using a broth microdilution method by exposing bacteria to stepwise increasing concentrations of T-3912 (Ozenoxacin). Selection of drug-resistant derivatives was carried out by exposure of 5. aureus SA113 and P. ctcnes JCM6425 to stepwise increasing concentrations of T-3912. A series of microtitre wells containing two-fold serial dilutions of T-3912 was inoculated with a final concentration of 10^5 cfu/mL and then incubated for 24 h for S. aureus SA113 and for 48 h for P. acnes JCM6425. In the next step, the well with the highest T-3912 concentration still showing turbidity was used to inoculate a new series of microtitre tray. The procedure was repeated, and the MICs were determined for up to 28 passages.
