Orbifloxacin
Based on 1 publication(s) in Google Scholar
Orbifloxacin is an orally administrable Antibiotic. Orbifloxacin disrupts the replication and proliferation of Bacterial DNA, inhibits bacterial growth and exerts bactericidal activity. Orbifloxacin inhibits the growth of canine-derived E. coli and Pseudomonas aeruginosa isolates. Orbifloxacin is used in research related to bacterial infections.

Orbifloxacin (0.015-4.0 μg/mL; up to 7 days) inhibits the growth of Piscirickettsia salmonis LF-89 VR-1361, and its growth-inhibitory effect persists throughout the 7-day incubation period compared with the untreated control group[1].
Orbifloxacin (0.1×-4× MIC; 0-24 h) inhibits the growth of Staphylococcus aureus ATCC 29213 and ATCC 43300, with MIC values of 0.5 mg/L and 4 mg/L, respectively, and induces concentration-dependent post-antibiotic effect (PAE) and post-antibiotic sub-MIC effect (PA-SME)[2].
Orbifloxacin (at twice the MIC; 1 h) induces a post-antibiotic effect (PAE) with an average duration of 0.29 h in clinical canine isolates of E coli, and an average PAE duration of 0.37 h in clinical canine isolates of Pseudomonas aeruginosa[3].
Orbifloxacin (0.1×MIC-0.3×MIC) induces concentration-dependent PA-SMEs in canine clinical isolates of E coli (mean 0.55 to 2.03 h) and Pseudomonas aeruginosa (mean 1.04 to 2.47 h)[3].
Orbifloxacin (0.016-16 mg/L; 18 h) inhibits visible growth of clinical Staphylococcus intermedius strains isolated from canine skin and ear infections by 50% and 90% at concentrations of 0.5 mg/L and 1 mg/L, respectively[4].
Orbifloxacin (0.063-4 mg/L; 1-24 h) exhibits concentration-dependent bactericidal activity against Staphylococcus aureus ATCC 29213, and time-dependent bactericidal activity against Staphylococcus intermedius isolates from pyoderma[4].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
