Revolade - Uses | Dosage | Interactions
Revolade contains eltrombopag and belongs to the group of thrombopoietin receptor agonists. Thrombopoietin is a glycoprotein hormone that stimulates the production and differentiation of megakaryocytes, which are responsible for the production of blood platelets. Revolade binds to the thrombopoietin receptor, exhibits agonistic effects and imitates the physiological function of thrombopoietin.
It is used for the treatment of immune (idiopathic) thrombocytopenic purpura when corticosteroid treatment, splenectomy (spleen removal) or immunoglobulin therapy did not yield adequate results. Thrombocytopenic purpura is caused by a reduced number of platelets which leads to an increased risk of bleeding. Patients with low platelet count may have the following symptoms: bruising, epistaxis, bleeding gums, petechiae (round, red spots that appear on the skin and are caused by bleeding into the skin layers) and difficulty in controlling and stopping the bleeding.
It is also used in patients with hepatitis C to allow the initiation of therapy with interferon.
It is also used in patients who have a severe form of aplastic anemia that does not respond to therapy with immunosuppressive drugs.
Peak plasma concentrations are achieved after 2-6 hours after oral administration. The largest part of the drug is excreted through the feces (60%) and about 30% is excreted through the urine.
There are no known contraindications to this medicine.
Caution should be exercised in patients with impaired hepatic function, as well as in patients who have had a thrombotic event or have a history of thrombotic events in the family. Revolade increases the risk of blood clot (thrombus) formation. Patients taking oral contraceptives and patients with obesity have an increased risk of thrombus formation, and Revolade should be used with caution in such patients.
