CODEINE FOR DUMMIES

Grapefruit Juice (GFJ)- I had toyed with the idea of making use of grapefruit juice for years but have read combined studies. Not long ago I browse that it does not inhibit CYP2D6 but rahter 3A4 which can be liable for conversion of codeine into norcodeine. In principle by inhibiting 3A4 you permit additional codeine for 2D6 to turn into morphine.
