		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 Linagliptin due to the transporter inhibition by Glasdegib

Recommended Action
Management		Caution is advised if glasdegib is coadministered with drugs that are substrates of P-gp and/or BCRP, particularly those with a narrow therapeutic range. Clinical and laboratory monitoring should be considered whenever glasdegib is added to or withdrawn from therapy with these drugs, and dosages adjusted as necessary. Patients should be monitored for the development of adverse effects.
