These studies produced no effects to the fetus. Developmental toxicity studies were performed in rats and rabbits. 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.

ABSTRACT: Gefitinib is an epidermal growth factor receptor tyrosine kinase inhibitor, a promising anticancer agent for the treatment of locally advanced or metastatic non-small cell lung cancer NSCLC especially in EGFR mutated patients. It acts by interfering with the proliferation and survival of cancer cells and other host dependent process promoting cancer cell growth by blocking signal transduction pathways. The major advantage of Gefitinib over standard chemotherapy is that it selectively inhibit cellular pathways involved in tumour survival with minimal effect on normal cells. Gefitinib was the first agent to be tested in clinical trials among tyrosine kinase inhibitors class of anticancer drugs. Gefitinib is a very slightly soluble novel anticancer drug whose solubility and dissolution can be improved by its complexation with cyclodextrins. Gefitinib is a generally well tolerated treatment, with skin rash and diarrhoea being the most common treatment adverse effects. Gefitinib has the potential of stimulating cell immunity against malignant cells. Binding of Gefitinib to human plasma protein is extensive. This article reviews the safety and efficacy of Gefitinib along with chemistry, mechanism, pharmacokinetics, drug interactions and special precautions to be taken in special cases like Geriatrics, Paediatrics, Pregnant women and nursing women during treatment with Gefitinib. Gefitinib showed no enzyme induction effects in animal studies. Human liver microsome studies demonstrated that in vitro Gefitinib was not a potent inhibitor of any human CYP enzyme activities. At the highest concentration studies, it produced approximately 50% inhibition of CYP2D6 77. When Gefitinib was co-administered with metoprolol a CYP2D6 substrate 35% increase in exposure to metoprolol was observed. Gefitinib is used in the treatment of non-small cell lung cancer.

The inhibition of in vitro EGFR activity, inhibition of EGF-stimulated tumour cell growth and blockage of autophosphorylation stimulated by EGF in tumour cells are the main functions of Gefitinib. Gefitinib restricts the EGF-stimulated growth of human umbilical vein endothelial cellsin comparison with FGF- or VEGF-stimulated growth. It has been found that Gefitinib is much more selective for EGFR than HER2. There is a major role of Gefitinib in inhibition of growth and phosphorylation of HER2 in numerous HER2-overexpressing cell lines 21-22. The EGFR is a 170-kd plasma membrane glycoprotein composing an extracellular ligand-binding domain and an intracellular protein tyrosine kinase domain. Extracellular ligand-binding domain is a transmembrane lipophillic segment and an intracellular protein tyrosine kinase TK domain has a regulatory carboxyl terminal segment 23-24.
