Abstract
A water-soluble three-layered oral mucosa-adhesive film made from hydroxypropyl cellulose containing dibucaine (0.25 mg of drug/cm(2)) was designed for alleviation of severe pain due to oral ulcers, caused by chemotherapy and/or radiotherapy. We report two patients with constant severe pain ulcers treated with the dibucaine film. Patients were asked to record the time that pain was relieved while chewing following first application of the film. Pain relief lasted for 2-5 h after application of the dibucaine film.
