Oxpentifylline is not effective for symptomatic oral lichen planus

BACKGROUND

There are no reliably effective therapies for oral lichen planus (OLP). The aim of the present work was to determine the potential efficacy of oxpentifylline in the management of OLP.

METHODS

Fifteen patients (six males, median age for the group 52 years, ranging from 33 to 72) with clinically and histopathologically confirmed OLP were treated with oxpentifylline at a dose of 400 mg three times daily.

RESULTS

Only 10 patients completed an 8 week course, the other five having to stop therapy because of adverse effects. Only three patients had any relief of their signs and symptoms of OLP.

CONCLUSION

The results indicate that oxpentifylline is unlikely to be of benefit for the treatment of OLP.

New and emerging therapies for diseases of the oral cavity

It is obvious from the review of the literature that most treatments for oral diseases such as lichen planus, pemphigoid, and pemphigus are based on case reports, anecdotes, and small uncontrolled studies. Efforts must be made to perform more controlled studies to evaluate the efficacy of new treatments. Small numbers of patients at each site and multiple-drug therapy make this task difficult. Dermatologists should familiarize themselves with the newer immunosuppressive agents available. Use of these drugs requires knowledge of their pharmacokinetics and potential side effects, so that they may be used effectively and safely. Relatively low doses of azathioprine, cyclophosphamide, and cyclosporine should then be added to the dermatologist's armamentarium for the treatment of severe or recalcitrant diseases. Old drugs are resurfacing with new (but often off-label) uses as the underlying mechanisms of disease become understood. Thalidomide and mycophenolate mofetil are two examples of promising drugs for the future of dermatology.
