Combined phenotypic assessment of cytochrome P450 1A2, 2C9, 2C19, 2D6, and 3A, N-acetyltransferase-2, and xanthine oxidase activities with the “Cooperstown 5+1 cocktail”

Previously, we have validated a 4-drug phenotyping cocktail, the "Cooperstown cocktail," using caffeine (cytochrome p450 [CYP] 1A2, N-acetyltransferase-2 [NAT2], and xanthine oxidase [XO]), dextromethorphan (CYP2D6), omeprazole (CYP2C19), and intravenous midazolam (hepatic CYP3A). Data suggest that ... View More
