 Cetuximab Brand name:- Erbitux , Lupitux  Cetuximab is a monoclonal antibody that specifically binds to receptors on cancer cells. Thus it flags the cancer cells for destruction by the body's immune system. Pharmacodynamic:- Cetuximab is an anticancer agent that works by inhibiting the growth and survival of epidermal growth factor receptor (EGFR)-expressing tumour cells with high specificity and higher affinity than epidermal growth factor (EGF) and transforming growth factor-alpha (TGF-α), which are natural ligands of EGFR. Cetuximab works by inhibiting the growth and survival of EGFR-positive tumours. In vitro, it promotes antibody-dependent cellular cytotoxicity (ADCC) against certain human tumour types. On the contrary, cetuximab does not exert its anti-tumour effects on human tumour xenografts lacking EGFR expression. Cetuximab potentiates the cytotoxic effects of chemotherapeutics and radiation therapy when used in combination. In human tumour xenograft models in mice,...
