These treatments require prolonged use, however, and are not always effective. Methods. In a double-blind trial, 16 patients with symptomatic oral lichen planus were randomly assigned to receive either topical cyclosporine or its vehicle. The patients swished and expectorated 5 ml of medication (containing 100 mg of cyclosporine per milliliter) three times daily. Results. After eight weeks, the eight recipients of cyclosporine had marked improvement in erythema (P = 0.003), erosion (P = 0.02), reticulation (presence of white lace-like lesions; P = 0.007), and pain (P = 0.002), whereas the eight recipients of vehicle had no change or minimal improvement. After a switch to cyclosporine for eight weeks, the vehicle-treated patients had improvement similar to that seen in the patients who initially received cyclosporin...
