From the Guidelines
Ofloxacin is not considered a "higher antibiotic" but rather a second-generation fluoroquinolone antibiotic with broad-spectrum activity. It works by inhibiting bacterial DNA gyrase and topoisomerase IV, which are essential enzymes for bacterial DNA replication, transcription, repair, and recombination. Ofloxacin is effective against many gram-positive and gram-negative bacteria, including some respiratory pathogens, urinary tract infection-causing organisms, and certain sexually transmitted infections. The typical adult dosage ranges from 200-400 mg twice daily, with adjustments needed for patients with renal impairment. Treatment duration varies by infection type, usually 3-14 days. Common side effects include nausea, diarrhea, headache, and dizziness. Serious adverse effects may include tendon damage, peripheral neuropathy, and QT interval prolongation. Ofloxacin should be used cautiously in elderly patients and those with seizure disorders, and it interacts with antacids, iron, and certain other medications that can reduce its absorption.
Some key points to consider when using ofloxacin include:
- It is effective against a wide range of bacteria, including some resistant strains 1
- It can be used to treat various infections, including respiratory, urinary tract, and sexually transmitted infections 1
- It has a broad spectrum of activity, but its use should be guided by susceptibility testing and clinical judgment 1
- It can interact with other medications and has potential side effects, so patients should be closely monitored 1
In terms of morbidity, mortality, and quality of life, ofloxacin can be an effective treatment option for various infections, but its use should be balanced with the potential risks and benefits. The most recent and highest quality study available should guide treatment decisions 1. Overall, ofloxacin is a valuable antibiotic option, but its use should be judicious and guided by clinical expertise and evidence-based guidelines.

From the Research
Antibiotic Properties
- Ofloxacin is a fluoroquinolone antibiotic with a broad spectrum of activity against aerobic Gram-negative and Gram-positive bacteria, although it is poorly active against anaerobes 2.
- It has rapid bactericidal activity against a wide variety of organisms, with its proposed mechanism of activity being interference with DNA gyrase, an enzyme essential for the replication of bacterial DNA 3.
- Ofloxacin is active against most Gram-negative bacteria, many Gram-positive bacteria, and some anaerobes, with ciprofloxacin being the only other quinolone with superior in vitro antibacterial activity 4.
Comparison with Other Antibiotics
- Ofloxacin has a superior pharmacokinetic profile compared to ciprofloxacin, with more rapid absorption and a peak serum concentration several times higher 4.
- Ciprofloxacin is a broad spectrum fluoroquinolone antibacterial agent that is effective in the treatment of a wide variety of infections, particularly those caused by Gram-negative pathogens 5.
- Ofloxacin and ciprofloxacin are both broad spectrum antibacterials available in both intravenous and oral formulations, offering the potential for cost savings with sequential intravenous and oral therapy in appropriately selected patients 2, 5.
Clinical Efficacy
- Clinical trials have confirmed the potential of ofloxacin for use in a wide range of infections, where it has generally proved as effective as standard treatments 2.
- Ofloxacin has been shown to be effective in the treatment of lower respiratory tract infections, urinary tract infections, and sexually transmitted diseases 6.
- Ciprofloxacin is effective in the treatment of a wide variety of infections, including complicated urinary tract infections, sexually transmitted diseases, skin and bone infections, and lower respiratory tract infections 5.
