Mechanism of Geftinat


Geftinat 250mg containing Gefitinib expels anti-tumor activity.

Gefitinib works by prohibiting tyrosine kinase phosphorylation occurs intracellularly which is related to cell surface receptors.

Gefitinib acts on cell surface of tumors by interfering with signal transduction by epidermal growth factor receptor.

This signal transfer is responsible for tumor cell division, blockade of apoptosis & elevating the production of angiogenic factors which is inducing metastasis.

Finally the inhibition of signal transduction stops all these functions of tumor cells leads to lyses.

Drug - drug interaction of Geftinat

Geftinat 250mg combined with strong CYP3A4 inducers like rifampicin, anti-convulsants causes elevating the Gefitinib metabolism and depletes the Gefitinib concentration.

To avoid this problem, the dose of Geftinat 250mg should be increased to 500mg then continue the therapy with 250mg as a single dose after the discontinuation of CYP3A4 inducers drugs.

Geftinat 250mg tablets co administered with strong CYP3A4 inhibitors causes diminishing the Gefitinib metabolism leads to increase the plasma concentration.

Geftinat 250mg should not be co administered with gastric regulator drugs, causes reduction in plasma concentration of Gefitinib.
