Enoxacin (ENX)

Enoxacin is an oral broad-spectrum fluoroquinolone antibacterial agent used in the treatment of urinary tract infections and gonorrhea. Insomnia is a common adverse effect. Enoxacin is a new fluoroquinolone compound structurally related to nalidixic acid. Its antimicrobial spectrum and activity are comparable to those of the fluoroquinolones norfloxacin and ciprofloxacin. It has a broad spectrum of activity against gram-negative and gram-positive microorganisms, but like the other fluoroquinolones it is less active against gram-positive micro-organisms. Anaerobic organisms are generally resistant to enoxacin. It is rapidly and nearly completely absorbed after oral administration and is distributed widely in body fluids and tissues. The drug is predominantly excreted via the kidney, with a relatively long serum elimination half-life of approximately five hours.
