It is approved to decrease the uncontrolled movements caused by Huntington’s disease.

Class of Drugs – Dopamine Depleter

Molecular Formula – C₁₉H₂₇NO₃

Molecular Weight – 317.4 g/mol

Working: This is an active component, which is dopamine deplete medicine. This active component Tetrabenazine works by inhibiting the vesicular monoamine transporter 2. Neurons are connected to each other by synapses and able to communicate via chemical signals called neurotransmitters. VMAT2 is responsible for regulating the neurotransmitters and its released across the synapse.

Uses: Given active medication is indicated to reduce the uncontrollable movements like chorea caused by Huntington’s disease. This is not a cure for the disease.

This medication belongs to a group of drugs called monoamine depletors.
