• Description: Ofloxacin is an antibacterial agent with increased potency in comparison to the prototype third generation quinolone, norfloxacin. It has a broad spectrum of activity against gram-positive and gram-negative bacteria and is useful in the treatment of kidney, genitourinary, and upper respiratory tract infections. Ofloxacin is a broad-spectrum fluoroquinolone antibiotic that prevents supercoiling of bacterial chromosomes by DNA gyrase. It is active against Gram-positive and Gram-negative bacteria with MIC90s ranging from 0.39 to 3.13 μg/ml for clinical isolates of S. aureus, S. epidermidis, S. pyogenes, and S. faecalis and ≤0.78 μg/ml for N. gonorrhoeae and various species of Enterobacteriaceae. Ofloxacin is active in vivo, with ED50 values ranging from 0.7 to 75.1 mg/kg in infected mice. Formulations containing ofloxacin have been used to treat urinary tract infections, gonorrhea, prostatitis, and gastroenteritis.
• Uses: Fluorinated quinolone antibacterial Ofloxacin is a fluorinated quinolone antibacterial.This compound is a contaminant of emerging concern (CECs).
• Indications: Ofloxacin also possesses a broad spectrum of antimicrobial action. It is highly active with respect to Gram-negative microorganisms, such as blue-pus bacillus, hemophilic and colon bacillus, shigella, salmonella, and chlamydia. It is used for infections of the respiratory tract, ears, throat, nose, skin, soft tissue, bones, joints, infective-inflammatory diseases of the abdominal cavity organs (kidneys, urinary tract), and organs of the pelvis minor (genitalia), and for gonorrhea. Synonyms of this drug are tarivid, flobacin, and others.
• Therapeutic Function: Antibacterial
• Clinical Use: 9-Fluoro-2,3-dihydro-3-methyl-10(4-methyl-1-piperazin-yl)-7-oxo-7H-pyrido[1,2,3-de]-1,4,-benzoxazine-6-carboxylicacid (Floxin, Floxin IV) is a member of the quinolone class of antibacterial drugs wherein the 1- and 8-positions are joined in the form of a 1,4-oxazine ring.Ofloxacin has been approved for the treatment of infectionsof the lower respiratory tract, including chronic bronchitisand pneumonia, caused by Gram-negative bacilli. It isalso used for the treatment of pelvic inflammatory diseaseand is highly active against both gonococci and chlamydia.In common with other fluoroquinolones, ofloxacin is not effectivein the treatment of syphilis. A single 400-mg oraldose of ofloxacin in combination with the tetracycline antibioticdoxycycline is recommended by the Centers forDisease Control and Prevention (CDC) for the outpatienttreatment of acute gonococcal urethritis. Ofloxacin is alsoused for the treatment of urinary tract infections caused byGram-negative bacilli and for prostatitis caused by E. coli.Infections of the skin and soft tissues caused by staphylococci,streptococci, and Gram-negative bacilli may also betreated with ofloxacin. Complicated and uncomplicated infections of the urinary tract, chronic prostatitis Uncomplicated urogenital and anorectal gonorrhea (single-dose), chancroid (3-day course), genital chlamydial infections (7-day course) Lower respiratory tract infections, including bronchopneumonia, community-acquired pneumonia (except pneumococcal pneumonia), acute bacterial exacerbations of chronic bronchitis (unless pneumococci are involved) and bronchiectasis Enteric fever, including the chronic carrier state; gastroenteritis caused by enterotoxigenic Escherichia coli, Salmonella, Shigella and Campylobacter spp. Ocular infections (ophthalmic preparation)
• Drug interactions: Potentially hazardous interactions with other drugs Aminophylline: possibly increased risk of convulsions, increased levels of aminophylline. Analgesics: increased risk of convulsions with NSAIDs. Anticoagulants: anticoagulant effect of coumarins enhanced. Antimalarials: manufacturer of artemether with lumefantrine advises avoid. Ciclosporin: increased risk of nephrotoxicity. Theophylline: possibly increased risk of convulsions.
