Study Summary

The purpose of this study is to test whether a mouthwash made with a drug called doxepin can reduce the pain caused by mouth sores resulting from radiation therapy. A number of mouth rinse preparations exist for patients with treatment-related oral mucositis pain such as the DLA rinse, an over-the-counter medication. This study will evaluate the effects of doxepin compared to DLA (diphenhydramine, lidocaine and antacids) and placebo.Doxepin is approved by the Food and Drug Administration (FDA) for the treatment of depression, anxiety, long-term pain management, as well as management of rash.

Primary Outcome

Total pain reduction (mouth and throat) was measured by the numerical analogue scale of mouth pain on a scale of 0 to 10, with 0=no pain and 10=worst pain in the questionnaires taken at baseline, and 5, 15, 30, 60, 120, 240 minutes after assigned treatment for doxepin or DLA vs. placebo. The total pain reduction was calculated by the (average of mouth and throat) area under the curve (AUC) adjusting for baseline, with time scale (baseline, 5, 15, 30, 60, 120 and 240 minutes post treatment) repla
