| Protein Function |
Involved in the ATP-dependent vesicular transport of biogenic amine neurotransmitters. Pumps cytosolic monoamines including dopamine, norepinephrine, serotonin, and histamine into synaptic vesicles (PubMed:23363473). Requisite for vesicular amine storage prior to secretion via exocytosis.

| Recommended Action | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| Management | Concomitant use of reserpine with either tetrabenazine or deutetrabenazine is considered contraindicated. Caution should be exercised when switching from reserpine to either medication. At least 20 days should elapse after stopping reserpine before initiating therapy with either tetrabenazine or deutetrabenazine. The physician is advised to wait for chorea to reemerge before administering tetrabenazine or deutetrabenazine to avoid monoamine over-depletion in the central nervous system. | ||||||||
