Abstract
Purpose of the Review
The need to develop novel pharmacological approaches for TS is balanced by the necessity for interventions to be safe and tolerable. This review provides an overview of studies of medications for TS over the last 3 years.
Recent Findings
Four studies of deutetrabenazine and valbenazine in TS failed in their primary outcomes. Ecopipam was more effective than placebo in reducing tics in children. Preliminary evidence suggests that a new endocannabinoid modulator (ABX-1431) has an acute effect on tics in adults. Intravenous valproic acid was more effective than oral aripiprazole in children with severe tics. Taurine added to tiapride was superior to placebo added to tiapride in decreasing tics in children. The clonidine patch and vitamin D decreased tics in children compared with baseline assessment. Behavioral therapy was as effective as pharmacotherapy in decreasing tics in children.
Summary
There is emerging evidence for new treatments for tics, but more methodologically rigorous studies are needed to inform practice recommendations.
