Ciprodex Otic Suspension acts by combining the antibacterial effects of ciprofloxacin with the anti-inflammatory properties of dexamethasone. Ciprofloxacin works by inhibiting the DNA gyrase and topoisomerase IV, enzymes essential for bacterial DNA replication, transcription, repair, and recombination. Dexamethasone, on the other hand, reduces the production of substances in the body that cause inflammation and discomfort. The dual-action formula is designed to quickly alleviate symptoms such as pain, swelling, and redness, making it an effective option for treating bacterial ear infections.
