CHEMOFIT 250MG contains gefitinib which has a place with a class of prescriptions called kinase inhibitors. It hinders a protein called 'epidermal development factor receptor' (EGFR). This protein is associated with development and spread of the malignant growth cells. It is utilized to treat with non-little cell cellular breakdown in the lungs. This malignant growth is a sickness where the threatening (disease) cells structure in tissues of the lung. Gefitinib acts by restraining 'epidermal development factor receptor' (EGFR) signal transduction pathways. EGFR is found on the outer layer of numerous malignant growth as well as should be expected cells which gets signal from different cells and sends it into the phone by causing a synthetic response that changes different proteins. By obstructing these signs, it hinders the development and increase of the cells.
