Gatiquin 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 DNA replication, transcription, repair, and recombination, 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 corneal ulcers. Gatiquin HS Eye Drop is typically administered as one to two drops in the affected eye(s) every 12 hours or as prescribed by a healthcare professional. It is well-tolerated with minimal systemic absorption, reducing the risk of systemic side effects. Patients should avoid contact lens use during treatment and adhere strictly to the prescribed dosage to prevent resistance development. Common adverse effects may include mild ocular irritation, burning sensation, or transient blurred vision. This medication is contraindicated in individuals with known hypersensitivity to gatifloxacin or other fluoroquinolones. Proper storage and handling are essential to maintain sterility and efficacy. Gatiquin HS Eye Drop offers an effective therapeutic option for managing bacterial ocular infections, ensuring rapid resolution and prevention of complications.
