Efficacy of Dronabinol for the Treatment of Cervical Dystonia

Summary

Cervical dystonia (CD) is characterized by abnormal, involuntary sustained cervical muscles contractions associated with twisting movements and abnormal postures of the neck that can be quite disabling. Currently there are no good oral medications for the treatment of CD. While botulinum toxin injections are effective in most, they require repeat injections and there are some patients who either stop responding or who never respond at all. Therefore, better treatments are needed. While the underlying mechanisms of dystonia are not entirely known, there is some information suggesting that it is ude to an underactivity of a chemical compound, GABA, that is located in the basal ganglia. Cannabinoids are a compound than can enhance transmission of GABA, and thus, may alleviate the symptoms of dystonia. Dronabinol, one such cannabinoid, has been widely used to treat anorexia and nausea in chemotherapeutic patients. The aim of this study, therefore, is to study the effect of dronabinol on cervical dystonia
