Gatifax-HS Eye Drop contains Gatifloxacin 0.5% w/v, a broad-spectrum fluoroquinolone antibiotic indicated for the treatment of bacterial infections of the eye. 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. This ophthalmic solution is effective against a wide range of Gram-positive and Gram-negative pathogens commonly implicated in ocular infections such as conjunctivitis and keratitis. Gatifax-HS Eye Drop is indicated for the treatment of bacterial conjunctivitis caused by susceptible strains of Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, and other relevant pathogens. The formulation is designed for topical application, ensuring high local drug concentration with minimal systemic absorption, reducing the risk of systemic side effects. It is generally well tolerated, with mild and transient adverse effects such as eye irritation, burning sensation, or dryness occasionally reported. Gatifax-HS Eye Drop should be used as prescribed by a healthcare professional, with adherence to recommended dosage and duration to prevent the development of antibiotic resistance. Patients should avoid contact lens use during treatment unless otherwise advised by their physician.
