Keytruda (Pembrolizumab) is used to treat certain types of cancers (skin cancer, non-small cell lung cancer). It works by changing the action of your own immune system, directing it to attack cancer cells. Keytruda (Pembrolizumab) belongs to a class of drugs known as monoclonal antibodies.
Mechanism of action:
Keytruda (Pembrolizumab) is an antibody drug that targets the cell surface receptor programmed cell death protein 1 (PD-1) found on T cells. By preventing the binding of its ligands (PD-L1 and PD-L2), Keytruda (Pembrolizumab) induces an antitumor immune response. Upregulation of PD-1 ligands is a mechanism for tumours to evade antitumor immune response; when PD-1 binds its ligand, the T cell receives an inhibitory signal leading to T cell anergy and blockade of anti tumour immune response. Instead of directly targeting tumor tissue to induce tumor cell death, Keytruda (Pembrolizumab) acts as a checkpoint inhibitor to stimulate immune responses to eliminate cancer cells.
Dosage and Administration:
Keytruda (Pembrolizumab) is given as an intravenous injection through a vein (IV) over 30 minutes every 3 weeks.
You may receive medications before the infusion to reduce allergic reactions.
The amount of Keytruda (Pembrolizumab) that you will receive depends on many factors, including your weight, your general health or other health problems, and the type of cancer or condition being treated. Your doctor will determine your dose and schedule.
