		Gene Name		ABCB1
		Uniprot ID		MDR1_HUMAN
		KEGG Pathway		hsa:5243
		Protein Family		ABC transporter superfamily
		Protein Function		Translocates drugs and phospholipids across the membrane (PubMed:8898203, PubMed:2897240, PubMed:9038218). Catalyzes the flop of phospholipids from the cytoplasmic to the exoplasmic leaflet of the apical membrane. Participates mainly to the flop of phosphatidylcholine, phosphatidylethanolamine, beta-D-glucosylceramides and sphingomyelins (PubMed:8898203). Energy-dependent efflux pump responsible for decreased drug accumulation in multidrug-resistant cells (PubMed:2897240, PubMed:9038218). Click to Show/Hide
Mechanism Description		Decreased clearance of Ubrogepant due to the transporter inhibition by Velpatasvir

Recommended Action
Management		The manufacturer recommends an initial ubrogepant dose of 50 mg when coadministered with BCRP and/or P-gp only inhibitors. If needed, a second 50 mg dose of ubrogepant may be administered at least 2 hours after the initial dose.
