gatifloxacin + ketorolac + prednisolone acetate

This is a **combination ophthalmic medication** comprised of three active pharmaceutical ingredients: - **Gatifloxacin**: a fourth-generation fluoroquinolone antibiotic. It inhibits bacterial DNA gyrase and topoisomerase IV, enzymes crucial for DNA replication, transcription, repair, and recombination, resulting in bacterial cell death. Used primarily for the treatment of bacterial conjunctivitis and other ocular infections[1][2][3][5][6]. - **Ketorolac**: a nonsteroidal anti-inflammatory drug (NSAID) that works by inhibiting cyclooxygenase (COX-1 and COX-2) enzymes, thereby blocking prostaglandin synthesis. This leads to reduced inflammation, pain, and swelling. In ophthalmology, it is utilized to control postoperative ocular pain and inflammation. - **Prednisolone acetate**: a synthetic glucocorticoid corticosteroid that suppresses inflammatory responses by inhibiting phospholipase A2 and therefore the formation of inflammatory mediators like prostaglandins and leukotrienes. It is commonly used in the eye to treat inflammation following surgery or from allergic or autoimmune causes. The combination is designed to provide **anti-infective (antibiotic), anti-inflammatory (corticosteroid), and analgesic (NSAID) effects** for managing postsurgical or infectious/inflammatory conditions in the eye. The synergistic approach allows simultaneous control over infection, inflammation, and pain. Primary use is **ophthalmic administration (eye drops)** for indications such as postoperative inflammation, infectious conjunctivitis with associated inflammation, and pain.
