WebGrapefruit juice is a potent inhibitor of the intestinal cytochrome P-450 3A4 system (specifically: CYP3A4 - mediated drug metabolism) which is responsible for the first-pass metabolism of many medications. This interaction can lead to increases in bioavailability and corresponding increases in serum drug levels.

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, CYP3A5, and CYP3A7, which are located in a multigene locus (CYP3A), play crucial roles in drug metabolism. To understand the highly variable hepatic expression of CYP3As, regulatory network analyses have focused on transcription factors (TFs). Since long non-coding RNAs (lncRNAs) likely contribute to such networks, we assessed the …
WebCYP3A4 is the most important form of P450 expressed in normal adult human livers, metabolizing up to 50% of all clinically used drugs.
