Actions and spectrum:Â
Cetuximab is a recombinant and humanized monoclonal antibody. It specifically binds to EGFR, c-ErB-1, and HER1 receptors over the surface of both tumor and normal cells. Moreover, cetuximab reduces the synthesis of matrix metalloproteinase and VEGF (vascular endothelial growth factor) and causes cell apoptosis. Cetuximab has been demonstrated to prevent tumor angiogenesis in vitro. EGFR expression is generally downregulated when cetuximab binds to EGFR and causes the antibody-receptor complex to internalize.Â

Pharmacology:Â
Cetuximab is a monoclonal antibody used for the treatment of a specific type of squamous cell carcinoma. Â
Pharmacodynamics:Â
An anticancer drug called cetuximab functions by selectively and more strongly suppressing the growth and survival of tumor cells that express the EGFR (epidermal growth factor receptor) than do EGF and TGF-α, which are EGFR’s natural ligands. Cetuximab functions by preventing EGFR-positive tumors from proliferating and from surviving. It encourages ADCC (antibody-dependent cellular cytotoxicity) against specific types of human tumors in vitro. Cetuximab, on the other hand, does not have any anti-tumor effects on human tumor xenografts that do not express EGFR.Â
Pharmacokinetics:Â
AbsorptionÂ
The area under the curve for cetuximab increases in a dose-dependent manner.Â
DistributionÂ
Volume of distribution of cetuximab is 2-3L/m2Â
MetabolismÂ
Cetuximab is known to undergo lysosomal degradation and protein catabolism.Â
Half-life:Â
112 hours.Â
Administration:Â
Cetuximab is administered as an intravenous injection. It is usually administered once a week or two weeks.Â
Before giving cetuximab, another drug can be given to lower specific side effects.Â

Pronunciation: se-tux-i-mabÂ
Cetuximab is an anti-cancer agent used to treat certain kinds of gastrointestinal cancer, including the colon or the rectum.
It is also used to treat neck and head cancer.
They are effective in retarding and cessing cancerous growth by binding with the EFGR protein receptor (epidermal growth factor receptor).
The medicine is given through the IV route once a week or two weeks.
Side effects may occur during the treatment, like vomiting, nausea, loss of appetite, redness in the eyes, flushing, and pain at the injection site.
You should inform your doctor about any side effects that get worsen.
Any previous or present allergy needs to be put forth before the doctor.
Avoid contact with the person who has recently been injected with a live vaccine.
You should inform your doctor about your current medication of cetuximab if you are undergoing any surgery or planning to conceive.
If you miss a dose, tell your healthcare professional to reschedule it.
There are no storage conditions provided as this medication is only administered in hospitals and is not to be stored or utilized at home.
