Clinical effects of flurbiprofen tooth patch on radiation-induced oral mucositis. A pilot study
Mucositis is an oral sequela of radiotherapy. In the development of mucositis several mechanisms play a role, such as inflammation and the effect of radiation on the high proliferation rate of oral basal epithelial cells. Therefore, administration of a drug with antiinflammatory and antiproliferative properties might delay the disorder and/or alleviate the severity of oral mucositis. The aim of this pilot study was to evaluate the effect of flurbiprofen in a tooth patch on the development, severity and duration of pseudomembranous mucositis in patients treated with curative head and neck radiotherapy.
The study group comprised 12 patients with a malignant tumor in the head and neck region to be treated with primary curative or postoperative radiotherapy. Patients applied once a day before sleep a flurbiprofen tooth patch to a natural tooth or upper denture during the full course of radiotherapy, starting 1 week before the onset of radiotherapy. Oral mucositis, pain, feeding, body weight and viability and maturation of epithelial cells were assessed. The results were compared with the findings in a historical control group.
No differences were found for severity and duration of pseudomembranous mucositis between the two groups. The onset of pseudomembranous/ulcerative mucositis occurred later in the flurbiprofen group (14.6±3.8 days, mean±SD) than in the historical control group (11±3.5 days; P<0.05).
This study shows that the flurbiprofen 15 mg tooth patch cannot prevent the development of pseudomembranous mucositis and has no influence on the duration of oral mucositis.
