Gefitinib inhibits all tyrosine phosphorylation sites on EGFR expressing cell lines. Tyr1173 and Tyr992 are less sensitive phosphorylation sites which require higher concentrations of Gefitinib for inhibition. These events occurred within several days and up to several months after initiating therapy and, in a few cases, within one month after stopping therapy.

Netupitant: May increase the serum concentration of CYP3A4 Substrates. Gefitinib undergoes extensive hepatic metabolism in humans, predominantly by CYP3A4. Three sites have been identified for biotransformation of Gefitinib including metabolism of the N-propoxymorpholino-group, demethylation of the methoxy-substituent on the quinazoline, and oxidative defluorination of the halogenated phenyl group. In vitro and in vivo studies indicated that Gefitinib is mainly metabolized by cytochrome P450-dependent CYP activities, including CYP3A4, CYP3A5 and CYP2D6 in the liver 44-46. The main metabolic pathway characterized by using human liver microsomes include morpholine ring opening, O-demethylation of the methoxy-substituent on the quinazoline ring structure and oxidative defluorination of the halogenated phenyl group 47-48.

So the activation of the is inhibited which is the function of the EGFR tyrosine kinase. The phosphorylation of several tyrosine kinases inside the cells is inhibited by Gefitinib, although Gefitinib has a role in antitumor effect in the association of tyrosine kinase with the epidermal growth factor receptor.
