1 Brain/blood ratios of methadone and ABCB1 polymorphisms in methadone-related deaths. Methadone ATP binding cassette subfamily B member 1 Homo sapiens
2 The aims of this study were (1) to determine whether brain/blood ratios can assist in the interpretation of methadone findings in fatalities; (2) to examine whether polymorphisms in the gene encoding the P-glycoprotein (also known as multidrug resistance protein 1 (MDR1) or ATP-binding cassette sub-family B member 1 (ABCB1)), which functions as a multispecific efflux pump in the blood-brain barrier, affect brain/blood ratios of methadone. Methadone ATP binding cassette subfamily B member 1 Homo sapiens

Methadone ATP binding cassette subfamily B member 1 Homo sapiens
4 Our results suggest that the rs1045642 polymorphisms in ABCB1 may affect methadone concentrations in the brain and its site of action and may be an additional factor influencing methadone toxicity. Methadone ATP binding cassette subfamily B member 1 Homo sapiens
5 Our results suggest that the rs1045642 polymorphisms in ABCB1 may affect methadone concentrations in the brain and its site of action and may be an additional factor influencing methadone toxicity. Methadone ATP binding cassette subfamily B member 1 Homo sapiens
