Theta oscillations vary with local response rate and are moderated by the dopamine-depleting agent, tetrabenazine, during effort-based behavior.
(PubMed, Cogn Affect Behav Neurosci)
- "We determined that the behavioral effects of TBZ were correlated with these neurophysiological changes across animals. Taken together, these findings demonstrate how TBZ may affect both theta dynamics and effortful behavior and suggest that the amplitude and frequency of theta band may vary with exertion of effort in motivated behavior."

Refractory tardive dyskinesia in the critical care setting: A case report of successful use of phenobarbital.
(PubMed, SAGE Open Med Case Rep)
- "Despite withdrawal of antipsychotics, a trial of deutetrabenazine, and high-dose tetrabenazine (150 mg/day for several weeks), symptoms persisted and significantly impaired critical care management. Given phenobarbital's activity on Gamma Aminobutyric Acid B receptors, its mechanism may involve modulation of GABAergic pathways implicated in the pathophysiology of tardive dyskinesia. Further investigation in clinical studies is warranted."

The role of the vesicular monoamine transporter 2 in the inhibitory effect of tetrabenazine and valbenazine compared to reserpine on the vesicular release of monoamine transmitters.
(PubMed, Front Cell Neurosci)
- "TBZ and VBZ are compared to RSP in that they also inhibit the vesicular release of neurotransmitters and storage capacity; however, their activity is less effective and is of much shorter duration, leaving some time for vesicle refilling. The difference observed between the two types of VMAT-2 inhibitors might give some explanation of why, in response to TBZ or VBZ treatment, the occurrence of depression or Parkinsonism as side effects is seen very rarely or not at all, and in the case of RSP, it is relatively frequent."

Exploring the Healthcare Resource Utilization (HCRU) Associated With Chorea in Patients With Huntington's Disease (HD): A Systematic Literature Review (SLR)
(ISPOR-EU 2025)
- "Risperidone was the most prescribed (26%), tetrabenazine (17%), other (6%), risperidone + tetrabenazine (6%), and deutetrabenazine (2%). Chorea imposes a substantial HCRU burden on patients with HD, which increases with chorea severity. Chorea imposes a substantial HCRU burden on patients with HD, which increases with chorea severity. Patients with the most severe chorea require more healthcare resources and experience greater impairments in work/daily functioning. Despite VMAT2 inhibitors being the only approved treatments for chorea in HD, their use remains limited—potentially due to costs."

Molecular basis of vesicular monoamine transport and neurological drug interactions.
(PubMed, Cell Rep)
- "Here, we report cryo-electron microscopy structures of human VMAT2 capturing a cytoplasmic-open state with reserpine and lumenal-facing states with serotonin and histamine in open, amphetamine in less open, tetrabenazine in fully occluded, and unbound VMAT2 in partially occluded conformations. Liposome-based analyses demonstrate that amphetamine directly induces the release of a fluorescent monoamine analog via VMAT2, consistent with an exchange mechanism underlying psychostimulation. These findings reveal the molecular basis of monoamine storage and drug interactions by VMAT2, informing therapeutic development for neurological diseases and substance abuse."

Dopamine antagonist effects of the D2/D3 receptor partial agonist aripiprazole on effort-based choice tasks in male and female rats.
(PubMed, Cogn Affect Behav Neurosci)
- "Previous research has shown that D2 receptor antagonists, such as haloperidol and eticlopride, produce a low-effort bias in rodents tested on effort-based choice...Furthermore, when DA tone was reduced by administration of the DA storage inhibitor tetrabenazine, aripiprazole did not increase lever pressing, instead producing a further decrease in male rats...Aripiprazole also increased c-Fos immunoreactivity in nucleus accumbens. These results indicate that aripiprazole acts as a D2 family functional antagonist on rat models of effort-based choice."

A proposed mechanism for amphetamine-induced behavioral sensitization involving the vesicular monoamine transporter.
(PubMed, Brain Res)
- "Rats were pretreated with a VMAT blocker, tetrabenazine (TBZ), before 7 daily AMPH injections (Induction Phase). Significantly, TBZ pretreatment blocked the sensitization of both 1) AMPH- and 2) electrical stimulation-evoked turning. These behavioral results support the hypothesis that VMAT modulates AMPH-sensitization via a mechanism for redistributing intraneuronal DA pools."
