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.

      Mechanism Description
  • Antagonize the effect of Zonisamide when combined with Ginkgo biloba 

Recommended Action
      Management Patients should consult a healthcare provider before taking any herbal or alternative medicine. Because of inconsistencies in formulation and potency of commercial herbal preparations, there is no way to verify without laboratory testing if and in what quantity 4'-O-methylpyridoxine may be present in a given ginkgo preparation. Patients treated with anticonvulsants should preferably avoid the use of products containing ginkgo biloba.
