Cinchona Overview
Cinchona is a genus of flowering plants belonging to the Rubiaceae family. It contains around 25 different species and is native to the Andes mountains of South America. One of the most well-known species is Cinchona calisaya. The bark of cinchona is a source of quinine, an alkaloid that has been used for centuries to treat malaria. Cinchona bark is also used in traditional medicine for a variety of other ailments, including muscle cramps, restless legs, fever, arthritis, and digestive disorders. As Cinchona contains quinine, it is sometimes used as a flavoring on tonic water and alcoholic drinks. Cinchona bark has been shown to contain, on average, 5% to 15% quinoline alkaloids.
Eltrombopag Overview
-
Eltrombopag is used to increase the number of platelets (cells that help the blood clot) to decrease the risk of bleeding in adults and children 1 year of age and older who have chronic immune thrombocytopenia (ITP; an ongoing condition that may cause unusual bruising or bleeding due to an abnormally low number of platelets in the blood) and who have not been helped or cannot be treated with other treatments, including medications or surgery to remove the spleen. Eltrombopag is also used to increase the number of platelets in people who have hepatitis C (a viral infection that may damage the liver) so that they can begin and continue treatment with interferon (Peginterferon, Pegintron, others) and ribavirin (Rebetol). Eltrombopag is also used in combination with other medications to treat aplastic anemia (condition in which the body does not make enough new blood cells) in adults and children 2 years of age and older. It is also used to treat aplastic anemia in adults who have not been helped with other medications. Eltrombopag is used to increase the number of platelets enough to decrease the risk of bleeding in people with ITP or aplastic anemia, or to allow treatment with interferon and ribavirin in people with hepatitis C. However it is not used to increase the number of platelets to a normal level. Eltrombopag should not be used to treat people who have low numbers of platelets due to conditions other than ITP, hepatitis C, or aplastic anemia. Eltrombopag is in a class of medications called thrombopoietin receptor agonists. It works by causing the cells in the bone marrow to produce more platelets.
