Objective: To test the antibacterial properties of three commercially available nasal corticosteroid preparations containing Mometasone Furoate (MF), Fluticasone Propionate (FP) and Fluticasone Furoate (FF) against S. pneumoniae, S. viridans, S. aureus, H. influenza, P. aeruginosa and E. coli.
Methods:
Study Design: Experimental in vitro study using the disc diffusion method.
Clinical isolates of Streptococcus pneumoniae, Hemophilus influenzae, Streptococcus viridans, Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli were inoculated on separate plates. 0.15 ml of nasal corticosteroid preparations containing MF, FP and FF were applied to blank paper discs, then placed on the plates, including an empty disc. Following 24 and 48 hours of incubation, the inhibition zones were measured to the nearest mm from the point of abrupt inhibition of growth.
Results: After 24 and 48 hours of incubation, S. pneumoniae, S. viridans, and S. aureus showed inhibition zones to all three preparations. S. aureus and S. viridans show the largest zones of inhibition at 24 and 48 hours respectively. H. influenza, P. aeruginosa and E. coli were negative. The inhibition zones of each bacteria were shown to be statistically different. The preparation containing FP had the largest zone of inhibition at 24 and 48 hours, although post hoc tests showed their difference was not significant.
Conclusion: The present study demonstrates possible antimicrobial properties of commercially-available nasal corticosteroid preparations. However, it is unclear whether these can be attributed to the steroids, their excipients, or both. Further studies testing each component may offer better insights into their therapeutic use.
