Mechanism of action

The therapy involves periodically filling the catheter lumen with a concentrated ethanol solution (typically 70-100%) that remains in contact with the catheter surface between uses. Ethanol exerts broad-spectrum antimicrobial activity against bacteria and fungi that colonize catheters and form biofilms, which are resistant to systemic antibiotics. This local approach reduces infection risk without systemic drug exposure.
