A drug used to treat
thrombocytopenia (low platelet levels) in patients with
immune thrombocytopenic purpura (ITP) that did not get
better with other treatment. ITP is a condition in which
platelets are destroyed by the immune system.
AMG 531 binds to the
thrombopoietin receptor, which causes the bone marrow to
make more platelets. It is a type of thrombopoietin
receptor agonist. Also called Nplate and romiplostim.
