Here, the Siroboon pills help to prevent the body from rejecting the newly transplanted kidney. This medicine helps to reduce the attacking activity of the immune cells on the new organ.

What Is The Mechanism Of Action Of Siroboon 5 Mg?

✓ How it Works:

When Sirolimus gets inside the cell, ll it attaches to a protein called FKBP-12. This Sirolimus and FKBP-12 then become a working team, a “drug-protein complex”.

✓ Stopping Cell Growth:

This team then blocks another protein called mTOR Complex 1 or mTORC1 for short. The mTORC1 protein usually tells cells to grow and divide, like a controller.

✓ Blocking immune proliferation:

The drug can stop the system from getting too strong. It does this by blocking the part that makes T-lymphocytes and B-lymphocytes multiply. These are types of blood cells that help fight off dreadful things in our bodies.

They multiply when they get a signal from things, like Interleukin-2.

✓ Cell Cycle Arrest:

The immune cells are stuck in a phase of their life. This phase is called the G1 to S phase. When they are stuck like this, they cannot.

Make more cells. This means they cannot attack an organ or anything else that is not supposed to be attacked by the immune system.

The drug puts the cells on hold so they cannot do any harm to the transplanted organ.
