Gatiquin Eye Drop contains Gatifloxacin 0.3% w/v, a broad-spectrum fluoroquinolone antibiotic effective against a wide range of gram-positive and gram-negative bacteria. It is indicated for the treatment of bacterial conjunctivitis and other superficial ocular infections caused by susceptible organisms. Gatifloxacin exerts its antibacterial effect by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for bacterial DNA replication, transcription, repair, and recombination, thereby leading to bacterial cell death. The ophthalmic formulation ensures targeted delivery to the infected site, minimizing systemic absorption and associated side effects. Gatiquin Eye Drop is typically administered as one or two drops into the affected eye(s) every two to four hours initially, followed by a reduced frequency as the infection resolves, according to the prescribing physician’s guidance. Patients should be advised to avoid contaminating the dropper tip and to discontinue use if hypersensitivity or severe irritation occurs. Gatiquin Eye Drop is contraindicated in individuals with known hypersensitivity to gatifloxacin or other quinolones. Caution is advised in patients with a history of ocular surface disorders. Proper diagnosis and susceptibility testing are recommended to ensure appropriate use and to reduce the risk of bacterial resistance.
