Study summary

The investigators want to study the effect of clobetasol in symptomatic oral lichen planus. The investigators will include 90 patients and randomly allocate them in three groups. The first group will receive active treatment both in the morning an evening. Group two receives placebo in the morning and active treatment in the evening. Group three will get placebo both in the morning and in the evening. All Groups will follow the same protocol with rinsing twice daily with test substance in conjunction with antifungal treatment. The patients will be controlled after two weeks and and again after another two weeks. A biopsy will be performed at inclusion and another biopsy will be taken at the end of the test period. Smears for candida will also be evaluated. The patients will be examined for changes in clinical appearance and will answer questions to note changes in symptoms. Our hypotheses: #Patients receiving clobetasol will have a better resolution af symptoms than those who got placebo. #Patients treated with clobetasol twice daily will have a faster relief of symptoms than patients just treated once daily. #The clinical signs of oral lichen planus will diminish more pronounced in the two groups given active treatment. #A majority of the OLP lesions were infected by candida. #Specific histological changes can be seen in the biopsies taken after clobetasol treatment compared to those taken before treatment.

Study arms

  • Active comparator
    Active/active

    The one bottle for use in the morning has clobetasol-oral gel, and so does the bottle fore use in the evening. The oral cavity will be rinsed with 5ml oral gel during 1 minute. Nystatin will be taken 1ml 4 times daily.

    Drug: Clobetasol Propionate

  • Active comparator
    Placebo/active

    The bottle for use in the morning contains placebo and one for use in the evening contains clobetasol oral gel. The oral cavity will be rinsed with 5ml oral gel during 1 minute. Nystatin will be taken 1ml 4 times daily.

    Drug: Placebo/Klobetasol APL oral gel 0.025%

  • Placebo comparator
    Placebo/placebo

    Both bottles, the one for the morning and the one for use in the evening, contains placebo. The oral cavity will be rinsed with 5ml oral gel during 1 minute. Nystatin will be taken 1ml 4 times daily.

    Drug: Placebo
