Use of Botulinum Toxin to Treat Psoriasis
|ClinicalTrials.gov Identifier: NCT00816517|
Recruitment Status : Completed
First Posted : January 1, 2009

Psoriasis vulgaris is a chronic disease in which psoriatic plaques may appear on the knees, elbows, scalp and trunk. Evidence suggests the role of neurogenic inflammation in the pathogenesis of psoriasis. Botulinum toxin has been shown to have an effect on inhibiting neurogenic inflammation.
Recently, it was reported that patients who suffered from dystonia and had concomitant psoriasis, when treated with botulinum toxin for dystonia noted a dramatic improvement of their psoriatic lesions.
This pilot study will determine the safety and efficacy of botulinum toxin in the management of psoriasis vulgaris.
