Georgetown University has selected Dr. Peretz to lead the MYSTICOL study for the Department of Neurology.

The MYSTICOL study tests the drug MYOBLOC, which already has been approved by the FDA for the treatment of cervical dystonia (abnormal, painful positioning of the head or neck). This multi-site study researches possible treatments for sialorrhea (drooling). The purpose of the study is to examine as to whether MYOBLOC can decrease the amount of saliva produced by the salivary glands, helping patients who suffer from conditions such as neurologic impairments, strokes, adult cerebral palsy, and diseases like Parkinson’s. Excessive salivation causes problems such as speech impairment, skin infections, and serious risks like choking or aspiration due to inhaling fluid.
