Overview
Eltrombopag tablets contain eltrombopag olamine, a small molecule thrombopoietin (TPO) receptor agonist for oral administration. Eltrombopag olamine is a biphenyl hydrazone. The chemical name for eltrombopag olamine is 3'-{(2Z)-2-[1-(3,4-dimethylphenyl)-3-methyl-5-oxo-1,5-dihydro-4H-pyrazol-4-ylidene]hydrazino}-2'-hydroxy-3-biphenylcarboxylic acid-2-aminoethanol (1:2). It has the molecular formula C 25 H 22 N 4 O 4 • 2(C 2 H 7 NO). The molecular weight is 564.65 g/mol for eltrombopag olamine and 442.48 g/mol for eltrombopag free acid. Eltrombopag olamine has the following structural formula: Eltrombopag olamine is a brown to red color solid, and is slightly soluble in methanol and practically insoluble in cyclohexane. Each eltrombopag tablet contains eltrombopag olamine in the amount of 15.95 mg, 31.90 mg, 63.80 mg or 95.70 mg equivalent to 12.5 mg, 25 mg, 50 mg or 75 mg of eltrombopag free acid respectively. The inactive ingredients of eltrombopag tablets are: Tablet Core: magnesium stearate, mannitol, microcrystalline cellulose, povidone and sodium starch glycolate. Coating: D&C red no. 27 (25 mg tablet), D&C yellow no. 10 (25 mg tablet), FD&C blue no. 1 (25 mg and 50 mg tablet), FD&C blue no. 2 (50 mg tablet), ferrosoferric oxide (75 mg tablet), hypromellose, iron oxide red (75 mg tablet), iron oxide yellow (75 mg tablet), polyethylene glycol, titanium dioxide. structure
How to use
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. ( 2.1 , 8.6 , 8.7 ) Chronic Hepatitis C-associated Thrombocytopenia: Initiate eltrombopag tablets at 25 mg orally once daily for all patients. Adjust to achieve target platelet count required to initiate antiviral therapy. Do not exceed a daily dose of 100 mg. ( 2.2 ) First-line Severe Aplastic Anemia: Initiate eltrombopag tablets orally once daily at 2.5 mg/kg (in pediatric patients aged 2 to 5 years old), 75 mg (pediatric patients aged 6 to 11 years old) or 150 mg for patients aged 12 years and older concurrently with standard immunosuppressive therapy. Reduce initial dose in patients of East-/Southeast-Asian ancestry. Modify dosage for toxicity or elevated platelet…
Side effects
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. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Amneal Pharmaceuticals LLC at 1-877-835-5472 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. Persistent or Chronic Immune Thrombocytopenia Adults In clinical trials, hemorrhage was the most common serious adverse reaction and most hemorrhagic reactions followed discontinuation of eltrombopag. Other serious adverse reactions…
Warnings
Important safety information
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) ] . WARNING: RISK FOR HEPATIC DECOMPENSATION IN PATIENTS WITH CHRONIC HEPATITIS C and RISK OF HEPATOTOXICITY See full prescribing information for complete boxed warning. In patients with chronic hepatitis C, eltrombopag in combination with interferon and ribavirin may increase the risk of hepatic decompensation. ( 5.1 ) Eltrombopag may increase the risk of severe and potentially life-threatening hepatotoxicity. Monitor hepatic function and discontinue dosing as recommended. ( 5.2 )
Interactions
Polyvalent Cations (Chelation) Eltrombopag chelates polyvalent cations (such as iron, calcium, aluminum, magnesium, selenium, and zinc) in foods, mineral supplements, and antacids. Take eltrombopag tablets 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) ] . 7.2 Transporters Use caution when concomitantly administering eltrombopag and drugs that are substrates of OATP1B1 (e.g., atorvastatin, bosentan, ezetimibe, fluvastatin, glyburide, olmesartan, pitavastatin, pravastatin, rosuvastatin, repaglinide, rifampin, simvastatin acid, SN-38 [active metabolite of irinotecan], valsartan) or breast cancer resistance protein (BCRP) (e.g., imatinib, irinotecan, lapatinib, methotrexate, mitoxantrone, rosuvastatin, sulfasalazine, topotecan). Monitor patients closely for signs and symptoms of excessive exposure to the drugs that are substrates of OATP1B1 or BCRP and consider reduction of the dose of these drugs, if appropriate. In clinical trials with eltrombopag, a dose reduction of rosuvastatin by 50% was recommended. 7.3 Protease Inhibitors HIV Protease Inhibitors: No dose adjustment is recommended when eltrombopag is co-administered with…
