Fluocinonide in an adhesive base for treatment of oral lichen planus. A double-blind, placebo-controlled clinical study

Abstract

Patients with symptomatic oral lichen planus frequently require therapy to reduce signs and symptoms. For this purpose, corticosteroids are often applied topically. In a randomized, double-blind, placebo-controlled study, the efficacy of the topical application of 0.025% fluocinonide was evaluated. Forty consecutive patients with oral lichen planus diagnosed on the basis of histopathologic and immunofluorescence findings participated in this study. All patients were followed for 3 to 17 months. No adverse effects were noted during follow-up period. In the group of 20 patients that received the drug, 4 patients (20%) showed a complete remission, and 12 patients (60%) had a good or partial response to topical treatment. In the placebo-group, these figures were 0 and 6 (30%), respectively. The majority of the placebo-group (70%) did not respond at all with regard to signs (Xt2 = 10.4; p = 0.0013) and symptoms (Xt2 = 6.97, p = 0.008). The results from this study suggest that topical application of fluocinonide in an adhesive base is a safe and effective drug to reduce signs and symptoms in oral lichen planus.
