When is Keytruda 50 mg Injection prescribed ?

• unresectable or metastatic melanoma.

How Does Keytruda (Pembrolizumab) Injection Work ?

In the body, there is a type of white blood cell that watches out for signs of infection or disease and can also assault cancer cells. These white blood cells are called T cells. On the surface of these T cells are certain proteins known as programmed cell death receptors (PD-1). So that T cells don’t destroy healthy cells, they use these surface proteins, or PD-1, to bind to and communicate with PD-L1 and PD-L2, proteins that permit cells to escape attack from the body’s immune system.

In other words, when the PD-1 protein on T cells comes in contact with PD-L1 and PD-L2 proteins, they are given the signal to allow that cell to live and spread. By blocking PD-1, Pembrolizumab increases the ability of your immune system to attack melanoma cells and tumors. This cancer medicine can release T cells so that it can penetrate melanoma anywhere in your body.
