Aims To investigate the efficiency of triclosan, ethylenediaminetetraacetic acid (EDTA) and cranberry alone or in combinations against Escherichia coli strains as urinary catheter lock solutions to reduce catheter‐associated urinary tract infections. Methods and Results Viable counting was used to assess antibiofilm activities for triclosan, EDTA and cranberry alone or in combinations against E. coli strains embedded in biofilm onto all‐silicon Foley catheter surface. The results revealed that combination of triclosan (10 mg ml −1 /EDTA 30 mg ml −1 ) when filling the catheter balloon was able to eradicate and prevent biofilm formation among all tested E. coli including the resistant strains, whereas triclosan (8·5 mg ml −1 )/ cranberry (103 mg ml −1 ) combination was a successful catheter lock solution by preventing all tested strains from adhering onto catheter surface when filled via the eye hole. Conclusions The combinations of triclosan/EDTA and triclosan/cranberry were significantly effective in eradicating and preventing biofilm formation of the tested E. coli strains on Foley catheters. Significance and Impact of the Study Combinations of triclosan/EDTA and triclosan/cranberry have a promising application as nonantibiotic catheter lock solution.
