Dyclonine is an local anesthetic used to provide topical anesthesia to mucous membranes through sodium channel inhibition. It is the active ingredient in Sucrets, an over-the-counter throat lozenge. It has been used as a local anesthetic agent prior to laryngoscopy, bronchoscopy, esophagoscopy, or endotracheal intubation. However, oral solutions no longer are commercially available in the US. Recently, additional activities of dyclonine have been discovered. Dyclonine represents a novel therapeutic strategy that can potentially be repurposed for the treatment of Friedreich's ataxia. Dyclonine enhances the cytotoxic effect of proteasome inhibitors on cancer and multiple myeloma cells.
