It has the molecular formula C 25 H 22 N 4 O 4 • 2(C 2 H 7 NO).
Uses
1 INDICATIONS AND USAGE Eltrombopag tablets are a thrombopoietin receptor agonist indicated: for the treatment of thrombocytopenia in adult and pediatric patients 1 year and older with persistent or chronic immune thrombocytopenia (ITP) who have had an insufficient response to corticosteroids, immunoglobulins, or splenectomy. Eltrombopag tablets should be used only in patients with ITP whose degree of thrombocytopenia and clinical condition increase the risk for bleeding. ( 1.1 ) for the treatment of thrombocytopenia in patients with chronic hepatitis C to allow the initiation and maintenance of interferon-based therapy.
Dosage
2 DOSAGE AND ADMINISTRATION Take eltrombopag tablets without a meal or with a meal low in calcium (≤ 50 mg). Take eltrombopag tablets at least 2 hours before or 4 hours after any medications or products containing polyvalent cations, such as antacids, calcium-rich foods, and mineral supplements. ( 2.4 , 7.1 , 12.3 ) Persistent or Chronic ITP: Initiate eltrombopag tablets at 50 mg orally once daily for most adult and pediatric patients 6 years and older, and at 25 mg orally once daily for pediatric patients aged 1 to 5 years. Dose reductions are needed for patients with hepatic impairment and some patients of East-/Southeast-Asian ancestry. Adjust to maintain platelet count greater than or equal to 50 x 10 9 /L. Do not exceed 75 mg per day.
Side Effects
6 ADVERSE REACTIONS The following clinically significant adverse reactions associated with eltrombopag are described in other sections. • Hepatic Decompensation in Patients with Chronic Hepatitis C [see Warnings and Precautions ( 5.1 )] • Hepatotoxicity [see Warnings and Precautions ( 5.2 )] • Increased Risk of Death and Progression of Myelodysplastic Syndromes to Acute Myeloid Leukemia [see Warnings and Precautions ( 5.3 )] • Thrombotic/Thromboembolic Complications [see Warnings and Precautions ( 5.4 )] • Cataracts [see Warnings and Precautions ( 5.5 )] Across all indications, the most common adverse reactions (≥ 20% in any indication) were: anemia, nausea, pyrexia, alanine aminotransferase increased, cough, fatigue, headache, and diarrhea.
Interactions
7 DRUG INTERACTIONS 7.1 Polyvalent Cations (Chelation) Eltrombopag chelates polyvalent cations (such as iron, calcium, aluminum, magnesium, selenium, and zinc) in foods, mineral supplements, and antacids. Take eltrombopag at least 2 hours before or 4 hours after any medications or products containing polyvalent cations, such as antacids, dairy products, and mineral supplements to avoid significant reduction in absorption of eltrombopag due to chelation [see Dosage and Administration ( 2.4 ), Clinical Pharmacology ( 12.3 )].
Warnings
WARNING: RISK FOR HEPATIC DECOMPENSATION IN PATIENTS WITH CHRONIC HEPATITIS C and RISK OF HEPATOTOXICITY In patients with chronic hepatitis C, eltrombopag in combination with interferon and ribavirin may increase the risk of hepatic decompensation [see Warnings and Precautions ( 5.1 )] . Eltrombopag may increase the risk of severe and potentially life-threatening hepatotoxicity. Monitor hepatic function and discontinue dosing as recommended [see Warnings and Precautions ( 5.2 )] . 5 WARNINGS AND PRECAUTIONS Hepatotoxicity: Monitor liver function before and during therapy. ( 5.2 ) Increased Risk of Death and Progression of Myelodysplastic Syndromes to Acute Myeloid Leukemia. ( 5.3 ) Thrombotic/Thromboembolic Complications: Portal vein thrombosis has been reported in patients with chronic liver disease receiving eltrombopag. Monitor platelet counts regularly. ( 5.4 ) 5.1 Hepatic Decompensation in Patients With Chronic Hepatitis C In patients with chronic hepatitis C, eltrombopag in combination with interferon and ribavirin may increase the risk of hepatic decompensation. 4 CONTRAINDICATIONS None. None. ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary Available data from a small number of published case reports and postmarketing experience with eltrombopag use in pregnant women are insufficient to assess any drug-associated risks for major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction and developmental toxicity studies, oral administration of eltrombopag to pregnant rats during organogenesis resulted in embryolethality and reduced fetal weights at maternally toxic doses.
