Highlights for gefitinib

CYP2D6 Inhibitors Strong: May decrease the metabolism of CYP2D6 Substrates. These kinds of changes are very mild and as the treatment will end, the liver will become almost normal. Primary clearance of Gefitinib is done by liver, so in case of patients who are suffering from hepatic dysfunction exposure of Gefitinib is increased. Gefitinib may increase liver enzymes, which could be a sign of liver problems. Patient liver function should be monitored by doctor using blood tests periodically during treatment. How should I store TAGRISSO? What are the possible side effects of BARACLUDE? In patients with hepatic impairment, systemic exposure to gefitinib may be increased, since drug is cleared principally by liver. 1 However, in patients with moderate to severe elevations of hepatic enzymes and liver metastases, pharmacokinetic profile was similar to that in patients without hepatic abnormalities; 1 9 effect of hepatic impairment unrelated to cancer not evaluated to date. Accelerated phase: 600 mg orally once a day. Gefitinib has the potential to stimulate cell immunity against malignant cells: It has been reported that Gefitinib activates platelets and RANTES Regulated on Activation, Normal T- cells Expressed and Secreted is released from the activated platelets and chemokine secretion by monocytes in the inflammatory lesion is regulated by the activated platelets 54. Lymphocyte migration is commenced at the focal tissue and monocytes are also activated resulting in several immune responses to tumour cells at the focal tissue. The clinical efficacy of Gefitinib therapy may be brought by the reduction in the angiogenesis via blockade of EGFR and thus causing tumour necrosis. AUC ratios of approximately 2 following oral dosing.



General information about gefitinib

Worsening of lung diseases and also death has been reported in some patients receiving Gefitinib treatment. Patients receiving chemotherapy or radiation therapy are more prone to high risk for lung disease. Chances to occur such problems are only 1% but if short of breath, high temperature and cough are likely to occur then patient should contact to physician immediately.

Patients aged 65 years or older may experience more grade 3 or 4 adverse events when this drug is used in combination with other agents compared with younger patients.

BARACLUDE, alone or in combination with antiretrovirals. 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. Gefitinib has been found to have antitumor activity in those patients who have become resistant to other anticancer drugs 4. The epidermal growth factor receptor EGFR is one transmembrane receptor tyrosine kinase of the human epidermal growth factor receptor HER family, has an important role in proliferation and metastasis of cancer cells. It is frequently over expressed in common solid tumours and has become a favoured target for orally administered small molecule and antibody-based therapy 5. The orally administered EGFR inhibitor Gefitinib was considered as third line therapy for non-small-cell lung cancer and was approved by Food and Drug Administration for treatment of cancer in may 2003 6. It was found in studies during phase I clinical trials that Gefitinib was active against non-small-cell lung cancer across a broad range of doses and studies during phase II clinical trials showed that response rate obtained was found in between 9% to 19% with the doses of 250 or 500 mg per day 7-8.

Liver function tests transaminases, bilirubin, and alkaline phosphatase should be monitored at baseline and at monthly intervals or as clinically appropriate. Abnormal results may be managed by interrupting treatment or decreasing the dose. 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.
