How PROMACTA treats chronic ITP in children

PROMACTA® (eltrombopag) is a platelet booster (aka, a “TPO-receptor agonist” or “platelet growth factor”). This means that it boosts the number of platelets your child’s body makes.


PROMACTA is the only platelet booster that is available as a tablet and an oral suspension. It is also the only oral platelet booster approved to treat chronic immune thrombocytopenia (ITP) in children 1 year and older.

How does PROMACTA work?

In some people with chronic ITP, the bone marrow isn’t making enough platelets to replace the ones the body destroys. To combat this, the person takes PROMACTA.

Instead of suppressing the immune system, like some other ITP treatments do, PROMACTA acts like a protein called thrombopoietin, which tells bone marrow cells to make more platelets.

Now that the body is making more platelets, platelet levels are boosted to a safe and stable level.
