The purpose of this pilot study was to assess the magnitude of effect for a new topical rinse that may impact oral soreness and function in ulcerative oral mucosal lesions. Twenty-five consecutive patients with ulcerative/erosion lesion and moderate pain visual analogue pain score (≥4) rated their mouth and throat soreness and oral symptoms at baseline and at 24, 48, and 72 hours after open-label use of a chitosan-based, nonanesthetic oral rinse (Synvaza) at least twice a day. No changes in prior therapy, including analgesics, were allowed during the trial. All measures of oral soreness decreased in severity from baseline to 72 hours, and overall oral soreness decreased by 28% (P < .01). Oral soreness associated with talking decreased by 67% (P < .01), drinking by 62% (P < .01), swallowing by 56% (P = .04), sleeping by 51% (P = .02) and eating by 50% (P < .01). The product was rated favorably for texture, flavor, soothing relief, mouth feel, and burning/stinging with use. Oral rinsing with the study product reduced mucosal pain without anesthetic effect and improved oral function.
