		Gene Name		SLC18A2
		Uniprot ID		VMAT2_HUMAN
		KEGG Pathway		hsa:6571
		Protein Family		Major facilitator superfamily
		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. Click to Show/Hide

		Gene Name		DRD2
		Uniprot ID		DRD2_HUMAN
		KEGG Pathway		hsa:1813
		Protein Family		G-protein coupled receptor 1 family
		Protein Function		Dopamine receptor whose activity is mediated by G proteins which inhibit adenylyl cyclase (PubMed:21645528). Positively regulates postnatal regression of retinal hyaloid vessels via suppression of VEGFR2/KDR activity, downstream of OPN5 (By similarity). Click to Show/Hide
Mechanism Description		Additive hypotensive effects by the combination of Deserpidine and Aripiprazole

Recommended Action
Management		Close clinical monitoring for development of hypotension is recommended if phenothiazines or neuroleptic agents are used in patients receiving antihypertensive medications or vasodilators. A lower starting dosage and slower titration of the phenothiazine or neuroleptic may be appropriate, especially in the elderly. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia. Patients should also avoid driving or operating hazardous machinery.
