Description
Curator's Comment:: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/6226242 | https://www.ncbi.nlm.nih.gov/pubmed/8429114 | https://www.ncbi.nlm.nih.gov/pubmed/8494374

Enoxacin is an oral broad-spectrum fluoroquinolone antibacterial agent used in the treatment of urinary tract infections and gonorrhea. Enoxacin is bactericidal drugs, eradicating bacteria by interfering with DNA replication. Like other fluoroquinolones, enoxacin functions by inhibiting bacterial DNA gyrase and topoisomerase IV. The inhibition of these enzymes prevents bacterial DNA replication, transcription, repair and recombination. Enoxacin is active against many Gram-positive bacteria. After oral administration enoxacin is rapidly and well absorbed from the gastrointestinal tract. The antibiotic is widely distributed throughout the body and in the different biological tissues. Tissue concentrations often exceed serum concentrations. The binding of enoxacin to serum proteins is 35 to 40%. The serum elimination half-life, in subjects with normal renal function, is approximately 6 hours. Approximately 60% of an orally administered dose is excreted in the urine as unchanged drug within 24 hours. Enoxacin, like other fluoroquinolones, is known to trigger seizures or lower the seizure threshold. The compound should not be administered to patients with epilepsy or a personal history of previous convulsive attacks as may promote the onset of these disorders.

Originator

Curator's Comment:: Enoxacin is a new pyridonecarboxylic acid derivative synthesized by Matsumoto et al.

Sample Use Guides

Enoxacin should be taken at least one hour before or at least two hours after a meal. For treatment uncomplicated urethral or cervical gonorrhea: 400 mg single dose. For treatment uncomplicated urinary tract infections 200 mg q12h for 7 days. For treatment complicated urinary tract infections: 400 mg q12h for 14 days. Dosage should be adjusted in patients with a creatinine clearance value of 30 mL/min/1.73 m 2 or less.
Route of Administration: Oral
In Vitro Use Guide
The in vitro antibacterial activity of AT-2266 (Enoxacin ) was tested by the determination of minimal bactericidal concentrations (MBCs) and the reduction of viable cells during exposure to the drug for 24 h. MIC90s of AT-2266 for P. aeruginosa resistant to gentamicin and Enterobacteriaceae resistant to nalidixic acid were 3.13 and 12.5 mkg/ml, respectively
