Fluoxetine The present study further confirms the in vitro inhibitory potential of this herb. Several herbal products have been known to modulate cytochrome P450 (CYP) enzymes and P-glycoprotein (P-gp) which are recognized as representative drug metabolizing enzymes and drug transporter, respectively. Since HIV protease inhibitors, macrolide antibiotics and azole antifungals along with many herbal agents are substrates of the same CYP3A4, these compounds can affect oral bioavailability of therapeutic agents indicated in the treatment of immunosuppression, cancer, AIDS and other opportunistic infections. The activity of this enzyme varies up to 40-fold and is affected by health, environment (smoking, diet, and co-medication), hormones, and genetics [3]. Tyrosine kinase inhibitors such as imatinib, osimertinib, and lapatinib, as a group, are also major CYP3A4 substrates. Therefore coffee should NOT be used as a CYP1A2 inhibitor.
