The work aimed at studying a new mucoadhesive prolonged release tablet containing 24 μg clobetasol-17 propionate (CP) suitable for the management of oral lichen planus. Low swellable dosage forms were designed by combining a mucoadhesive polymer, i.e. poly(sodium methacrylate, methylmethacrylate), with hydroxypropylmethylcellulose and MgCl₂. This formulation was selected to modify the tablet erosion rate in order to obtain a release of CP over a 6-h period. A double-blind, controlled study was performed using three groups of patient (n=16) who received three applications-a-day over 4 weeks of the developed CP tablets (group CP-T), placebo tablets (group CP-P) or commercial CP ointment for cutaneous application (123 μg/application) extemporary mixed with Orabase™ (group CP-O). At the end of the study, pain and ulceration resolved in 13/16 and 11/16 patients of group CP-T and group CP-O, respectively. In the group CP-O, a transient acute hyperaemic candidosis (n=2) and taste alteration (n=4) were also observed. No changes in clinical signs of patients in the group CP-P were evident. The application of mucoadhesive tablet containing 24 μg CP 3 times a day appeared to be effective, avoiding the side effects of the generally used treatment.
