Ciprofloxacin in Otitis Externa Management: Efficacy, Safety, and Future Directions

Ciprofloxacin, a fluoroquinolone antibiotic, plays a crucial role in treating otitis externa, which is a com- mon inflammatory disorder of the outer ear canal. This review examines the effectiveness and safety of ciprofloxacin in managing otitis externa, with a focus on its pharmacological properties, antibacterial effects, and outcomes. This review highlights the potent activity of ciprofloxacin against the primary pathogens Pseudomonas aeruginosa and Staphylococcus aureus and its ability to penetrate the auditory canal, making it ideal for treating ear infections. The use of oral ciprofloxacin in severe cases, particularly in malignant otitis externa, is also discussed. This review ex- plores the benefits and drawbacks of topical and oral ciprofloxacin formulations and the rationale for combining these routes in complex cases. Special attention should be given to prescribing ciprofloxacin to vulnerable popu- lations, such as children, the elderly, and pregnant women. The increasing prevalence of ciprofloxacin-resistant bacteria and the importance of antimicrobial stewardship programs in combating resistance are emphasized. This review addresses drug interactions and monitoring strategies. Future directions in otitis externa treatment are discussed, including the development of safer quinolones, advancements in targeted drug delivery systems, and progress in diagnostic tools for antibiotic selection. This review underscores the significance of ciprofloxacin in managing otitis externa while highlighting the need for judicious use and research to optimize outcomes and miti- gate resistance risk.
