What this trial studies

This clinical trial evaluates the effectiveness of a 0.08% tacrolimus nanoencapsulated aqueous solution spray versus a 0.1% free tacrolimus commercial ointment in treating oral lichen planus. Participants will apply one of the formulations twice daily for one month and attend clinic visits every two weeks for assessments. The study aims to determine which formulation leads to longer periods without lesions. The trial is designed to provide insights into the efficacy of different drug delivery methods for this condition.

Who should consider this trial

Good fit: Ideal candidates are individuals diagnosed with erosive or ulcerative oral lichen planus.

Not a fit: Patients with a history of oral cancer, allergic reactions to tacrolimus, or significant immunosuppression may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a more effective treatment option for patients suffering from oral lichen planus.

How similar studies have performed: Other studies have explored tacrolimus for oral lichen planus, but the nanoencapsulation approach is relatively novel.
