ποΈπ¦ π§ Ciprofloxacin 0.3% Eye/Ear Drops: Broad-Spectrum Antibiotic for Bacterial Infections
Ciprofloxacin 0.3% is a topical antibiotic solution widely used in the form of eye drops (ophthalmic) or ear drops (otic) for the treatment of various bacterial infections. It belongs to the fluoroquinolone class of antibiotics and works by killing or inhibiting the growth of bacteria causing infections in the eyes or ears. This medication is effective against a broad range of gram-positive and gram-negative bacteria, making it a go-to treatment for conjunctivitis, corneal ulcers, otitis externa, and post-surgical prophylaxis.
π¬ Mechanism of Action
Ciprofloxacin works by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes necessary for DNA replication, transcription, and repair. This inhibition prevents bacteria from multiplying, ultimately leading to bacterial death.
