Romiplostim
Novel biologic agent that activates the thrombopoietin receptor, approved for idiopathic thrombocytopenic purpura
Romiplostim is a type of medication used to treat low platelet count in individuals with chronic immune thrombocytopenia (ITP), a condition in which the body’s immune system attacks and destroys platelets. Romiplostim is a synthetic protein that mimics the action of a hormone called thrombopoietin (TPO), which is responsible for stimulating the production of platelets in the bone marrow.
By binding to the TPO receptor on the surface of platelet progenitor cells, romiplostim stimulates the production of new platelets, which can increase platelet counts and reduce the risk of bleeding in individuals with ITP. Romiplostim is given as a subcutaneous injection once a week, with the dosage adjusted based on the individual’s platelet count response.
When using romiplostim, it is important to monitor platelet counts regularly and adjust the dosage as needed to achieve optimal results. Possible side effects of romiplostim include headache, fatigue, muscle aches, nausea, and allergic reactions. It is important to inform your healthcare provider of any medications or supplements you are taking before starting romiplostim, as it may interact with other drugs. Regular monitoring of liver function is also recommended while using romiplostim.
