Later on investigators ended up ready to exhibit that The shortcoming to metabolize these drugs was a recessive trait [24]; was present in close to 5-10% of Europeans; and that the inability to oxidize sparteine was affiliated with The lack to hydroxylate debrisoquine [25], suggesting that metabolism of these two drugs was by exactly the same enzyme.
