The purpose of this clinical trial is to study the therapeutic effect of tetrabenazine MR in children with Tourette's Syndrome, as measured by the improvement in total tic score of the Yale Global Tic Severity Scale (YGTSS).
Tourette's Syndrome (TS) is typically diagnosed in early childhood (6-7 years) or before the age of 21 years and is characterized by chronic, intermittent motor and phonic tics. There is a body of evidence, mostly from the clinical experience data, suggesting the efficacy of tetrabenazine in TS patients with tics, including patients who were unresponsive to other treatment options. These publications consistently report the usefulness of tetrabenazine as an alternative to conventional neuroleptics for the treatment of TS.

Although antipsychotics are used to treat Tourette syndrome, there have been reports of paradoxical induction of tics by first- and second-generation antipsychotics.
To describe recent advances regarding the disease spectrum in Tourette syndrome, offer new mechanistic insights into tic generation and provide clues for personalized treatments in this disorder.
While previous studies have investigated the effect of repetitive transcranial magnetic stimulation (rTMS) in treating Tourette syndrome (TS), the results remain inconclusive.
Tourette syndrome (TS) is a neuropsychiatric disorder characterized by childhood onset motor and phonic tics. In refractory cases, deep brain stimulation (DBS) with different targets including anterom...

A drug formerly used as an antipsychotic and treatment of various movement disorders. Tetrabenazine blocks neurotransmitter uptake into adrenergic storage vesicles and has been used as a high affinity label for the vesicle transport system.
A diphenylbutylpiperidine that is effective as an antipsychotic agent and as an alternative to HALOPERIDOL for the suppression of vocal and motor tics in patients with Tourette syndrome. Although the precise mechanism of action is unknown, blockade of postsynaptic dopamine receptors has been postulated. (From AMA Drug Evaluations Annual, 1994, p403)
Drugs that bind to but do not activate DOPAMINE RECEPTORS, thereby blocking the actions of dopamine or exogenous agonists. Many drugs used in the treatment of psychotic disorders (ANTIPSYCHOTIC AGENTS) are dopamine antagonists, although their therapeutic effects may be due to long-term adjustments of the brain rather than to the acute effects of blocking dopamine receptors. Dopamine antagonists have been used for several other clinical purposes including as ANTIEMETICS, in the treatment of Tourette syndrome, and for hiccup. Dopamine receptor blockade is associated with NEUROLEPTIC MALIGNANT SYNDROME.
A phenyl-piperidinyl-butyrophenone that is used primarily to treat SCHIZOPHRENIA and other PSYCHOSES. It is also used in schizoaffective disorder, DELUSIONAL DISORDERS, ballism, and TOURETTE SYNDROME (a drug of choice) and occasionally as adjunctive therapy in MENTAL RETARDATION and the chorea of HUNTINGTON DISEASE. It is a potent antiemetic and is used in the treatment of intractable HICCUPS. (From AMA Drug Evaluations Annual, 1994, p279)
Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
