WebNov 6, 2014 · Metabolism of codeine to norcodeine via CYP3A4 is normally a minor pathway, but under certain circumstances CYP3A4 can play a role. In a person with normal CYP2D6 activity, giving CYP3A4 inhibitors has little effect because of the small percentage of codeine sthat is metabolized in this manner. WebCYP3A4, which it induces, is also responsible for its clearance (Acocella, 1978). The prediction of in vivo phenomena in humans may be attempted with in vitro experiments. To establish valid in vitro models, reliable in vitro-in vivo correlations must be established with laboratory animal models. Rat orthologs of human CYP3A4 are CYP3A1, -3A2,
