Abstract
Purpose: Commercially available chlorhexidine gluconate (CHG) has a beyond-use date of 24 h. This study evaluated the stability and sterility of 0.05% CHG for 30 days after opening and compared its cost to povidone iodine (PI) for intravitreal injection antisepsis. Methods: 0.05% CHG was aliquoted into 1-mL syringes and stored at room temperature or refrigerated. Turbidity, pH, high-performance liquid chromatography (HPLC), and sterility testing were performed. A cost analysis was conducted. Results: 0.05% CHG remained stable for at least 30 days. All samples had measured turbidity <0.5 nephelometric turbidity units. The pH of all samples remained between 5.0 and 7.0. HPLC demonstrated CHG concentration at day 30 relative to day 0 of 98.52% ± 4.16% at room temperature and 99.99% ± 3.38% at 2°C -6°C. The cost per week to perform 150 injections using 0.05% CHG was $463.25 when opening a new bottle daily compared with $16.73 for 5% PI. This cost decreased to $23.16 when utilizing a bottle of CHG for 30 days. Conclusion: 0.05% CHG remains stable and sterile for at least 30 days after opening. The ability to use CHG for at least 30 days after its opening significantly decreases its utilization expense.
