Treats respiratory infections (including pneumonia and bronchitis), urinary tract infections, sinusitis, and gonorrhea. May also be used for skin and soft tissue infections when caused by susceptible bacteria.
As a fluoroquinolone, gatifloxacin inhibits two key bacterial enzymes: DNA gyrase and topoisomerase IV. These enzymes are essential for bacterial DNA replication, transcription, and repair. By blocking these enzymes, the medication prevents bacterial growth and reproduction.
Common side effects include nausea, diarrhea, headache, and dizziness. Fluoroquinolones may increase risk of tendon damage, especially in patients over 60 or those on corticosteroid therapy. Should be avoided in patients with known quinolone hypersensitivity. Not recommended for children or pregnant women unless no alternatives exist.
