🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes that are essential for bacterial DNA replication, transcription, repair, and recombination. By blocking these enzymes, it prevents the supercoiling and relaxation of bacterial DNA, leading to disruption of DNA synthesis and ultimately bacterial cell death. This medicine is bactericidal against susceptible organisms.

Dosage Information
| Adult Dosage | The usual adult dose of this medicine for uncomplicated urinary tract infections is 400 mg taken orally twice daily for 3 to 7 days, depending on the severity of the infection and clinical response. For other infections, the dose and duration may vary. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.

If you experience pain, swelling, or rupture of a tendon, stop the medicine and seek medical attention immediately.
