Abstract: PURPOSE: To assess the effects of DICLORAL’s alleviation of pain caused by radiation-induced oral mucositis. METHODS:With compound borax solution as a comparative drugs, the solution of DICLORAL was adopted for patients with radiation-induced oral mucositis due to radiotherapy for nasal NK/T cell lymphoma. All 59 patients were randomly divided into 2 groups: experimental group (using DICLORAL) and control group (using Compound Borax Solution). During the treatment, we observed drugs’ ability of alleviate oral pain or pain on swallowing, when it worked and how long it could sustain in controlling pain. Statistical analysis was performed using SPSS 16.0 software package. RESULTS: Drugs’ ability of alleviate oral pain or pain on swallowing and the onset time was not significantly different between the 2 groups (P>0.05). Effective duration in experimental group was longer than that in control group (P<0.05). CONCLUSIONS: DICORAL can alleviate and cease pain caused by radiation-induced oral mucositis effectively.
