🩺 Clinical
Eltrombopag is used to treat thrombocytopenia (a low number of platelets [type of blood cell needed for blood clotting]) and aplastic anemia (condition in which the body does not make enough new blood cells). 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.

⏳ Availability & generic status
The FDA lists approved generic versions of this medicine, but that does not always mean a pharmacy can get one today. Patent rules, launch agreements, supply and pricing can affect when generics actually arrive.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Take PROMACTA without a meal or with a meal low in calcium (≤ 50 mg). Take PROMACTA 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 PROMACTA 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 PROMACTA 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 PROMACTA 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 counts.
( 2.3 , 8.7 ) Refractory Severe Aplastic Anemia: Initiate PROMACTA orally at 50 mg once daily. Reduce initial dose in patients with hepatic impairment or patients of East-/Southeast-Asian ancestry. Adjust to maintain platelet count greater than 50 x 10 9 /L.
Do not exceed 150 mg per day. ( 2.3 , 8.6 , 8.7 )
2.1Persistent or Chronic Immune Thrombocytopenia Use the lowest dose of PROMACTA to achieve and maintain a platelet count greater than or equal to 50 x 10 9 /L as necessary to reduce the risk for bleeding. Dose adjustments are based upon the platelet count response. Do not use PROMACTA to normalize platelet counts [see Warnings and Precautions (5.4)].
In clinical trials, platelet counts generally increased within 1 to 2 weeks after starting PROMACTA and decreased within 1 to 2 weeks after discontinuing PROMACTA [see Clinical Studies (14.1)] . Initial Dose Regimen: Adult and Pediatric Patients 6 Years and Older with ITP: Initiate PROMACTA at a dose of 50 mg orally once daily, except in patients who are of East-/Southeast-Asian ancestry or who have mild to severe hepatic impairment (Child-Pugh class A, B, C). For patients of East-/Southeast-Asian ancestry with ITP, initiate PROMACTA at a reduced dose of 25 mg orally once daily [see Use in Specific Populations (8.7), Clinical Pharmacology (12.3)].
For patients with ITP and mild, moderate, or severe hepatic impairment (Child-Pugh class A, B, C), initiate PROMACTA at a reduced dose of 25 mg orally once daily [see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)] . For patients of East-/Southeast-Asian ancestry with ITP and hepatic impairment (Child-Pugh class A, B, C), consider initiating PROMACTA at a reduced dose of 12.5 mg orally once daily [see Clinical Pharmacology (12.3)] . Pediatric Patients with ITP Aged 1 to 5 Years: Initiate PROMACTA at a dose of 25 mg orally once daily [see Use in Specific Populations (8.7), Clinical Pharmacology (12.3)] .
Monitoring and Dose Adjustment: After initiating PROMACTA, adjust the dose to achieve and maintain a platelet count greater than or equal to 50 x 10 9 /L as necessary to reduce the risk for bleeding. Do not exceed a dose of 75 mg daily. Monitor clinical hematology and liver tests regularly throughout therapy with PROMACTA and modify the dosage regimen of PROMACTA based on platelet counts as outlined in Table 1.
During therapy with PROMACTA, assess complete blood counts (CBCs) with differentials, including platelet counts, weekly until a stable platelet count has been achieved. Obtain CBCs with differentials, including platelet counts, monthly thereafter. When swi…

⚠️ Warnings and Cautions ▾
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 PROMACTA. Monitor platelet counts regularly. ( 5.4 )
5.1Hepatic Decompensation in Patients With Chronic Hepatitis C In patients with chronic hepatitis C, PROMACTA in combination with interferon and ribavirin may increase the risk of hepatic decompensation. In two controlled clinical trials in patients with chronic hepatitis C and thrombocytopenia, ascites and encephalopathy occurred more frequently on the arm receiving treatment with PROMACTA plus antivirals (7%) than the placebo plus antivirals arm (4%). Patients with low albumin levels (less than 3.5 g/dL) or Model for End-Stage Liver Disease (MELD) score greater than or equal to 10 at baseline had a greater risk for hepatic decompensation on the arm receiving treatment with PROMACTA plus antivirals.
Discontinue PROMACTA if antiviral therapy is discontinued.
5.2Hepatotoxicity PROMACTA may increase the risk of severe and potentially life-threatening hepatotoxicity [see Adverse Reactions (6.1)] . One patient (< 1%) with ITP treated with PROMACTA in clinical trials experienced drug-induced liver injury. Eleven patients (1%) with chronic hepatitis C treated with PROMACTA in clinical trials experienced drug-induced liver injury.
Treatment of ITP, Chronic Hepatitis C-associated Thrombocytopenia, and Refractory Severe Aplastic Anemia Measure serum ALT, AST, and bilirubin prior to initiation of PROMACTA, every 2 weeks during the dose adjustment phase, and monthly following establishment of a stable dose [see Drug Interactions (7.5)] . PROMACTA inhibits UDP-glucuronosyltransferase (UGT)1A1 and organic anion-transporting polypeptide (OATP)1B1, which may lead to indirect hyperbilirubinemia. If bilirubin is elevated, perform fractionation.
Evaluate abnormal serum liver tests with repeat testing within 3 to 5 days. If the abnormalities are confirmed, monitor serum liver tests weekly until resolved or stabilized. Discontinue PROMACTA if ALT levels increase to greater than or equal to 3 x ULN in patients with normal liver function or greater than or equal to 3 x baseline (or greater than 5 x ULN, whichever is the lower) in patients with pre-treatment elevations in transaminases and are: progressively increasing, or persistent for greater than or equal to 4 weeks, or accompanied by increased direct bilirubin, or accompanied by clinical symptoms of liver injury or evidence for hepatic decompensation.
If the potential benefit for reinitiating treatment with PROMACTA is considered to outweigh the risk for hepatotoxicity, then consider cautiously reintroducing PROMACTA and measure serum liver tests weekly during the dose adjustment phase. Hepatotoxicity may reoccur if PROMACTA is reinitiated. If liver test abnormalities persist, worsen, or recur, then permanently discontinue PROMACTA.
First-Line Treatment of Severe Aplastic Anemia Measure ALT, AST, and bilirubin prior to initiation of PROMACTA, every other day while hospitalized for h-ATG therapy, and then every 2 weeks during treatment. During treatment, manage increases in ALT or AST levels as recommended in Table 6.
5.3Increased Risk of Death and Progression of Myelodysplastic Syndromes to Acute Myeloid Leukemia A randomized, double-blind, placebo-controlled, multicenter trial in patients with International Prognostic Scoring System (IPSS) intermediate-1, intermediate-2 or high risk MDS with thrombocytopenia, receiving azacitidine in combination with either PROMACTA (n = 179) or placebo (n = 177) was terminated due to lack of efficacy and safety reasons, including increased progression to acute myeloid leukemia (AML). Patients received PROMACTA or placebo at a starting dose of 200 mg once daily, up to a maxim…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following clinically significant adverse reactions associated with PROMACTA 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.

6.1Clinical 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 PROMACTA. Other serious adverse reactions included thrombotic/thromboembolic complications [see Warnings and Precautions (5.4)] .
The data described below reflect exposure of PROMACTA to patients with persistent or chronic ITP aged 18 to 85 years, of whom 66% were female, in three placebo-controlled trials and one open-label extension trial [see Clinical Studies (14.1)] . PROMACTA was administered to 330 patients for at least 6 months and 218 patients for at least 1 year. Table 8 presents the most common adverse drug reactions (experienced by greater than or equal to 3% of patients receiving PROMACTA) from the three placebo-controlled trials, with a higher incidence in PROMACTA versus placebo.
Table 8. Adverse Reactions (≥ 3%) From Three Placebo-controlled Trials in Adults With Persistent or Chronic Immune Thrombocytopenia Abbreviations: ALT, alanine aminotransferase; AST, aspartate aminotransferase. a Includes PTs of urinary tract infection, cystitis, urinary tract infection bacterial, and bacteriuria. Adverse reaction PROMACTA 50 mg n = 241 (%) Placebo n = 128 (%) Nausea 9 3 Diarrhea 9 7 Upper respiratory tract infection 7 6 Vomiting 6 < 1 Urinary tract infection a 5 4 Increased ALT 5 3 Myalgia 5 2 Oropharyngeal pain 4 3 Increased AST 4 2 Pharyngitis 4 2 Back pain 3 2 Influenza 3 2 Paresthesia 3 2 Rash 3 2 In the three controlled clinical persistent or chronic ITP trials, alopecia, musculoskeletal pain, blood alkaline phosphatase increased, and dry mouth were the adverse reactions reported in 2% of patients treated with PROMACTA and in no patients who received placebo.
Among 302 patients with persistent or chronic ITP who received PROMACTA in the single-arm extension trial, the adverse reactions occurred in a pattern similar to that seen in the placebo-controlled trials. Table 9 presents the most common treatment-related adverse reactions (experienced by greater than or equal to 3% of patients receiving PROMACTA) from the extension trial. Table 9.

7 DRUG INTERACTIONS
7.1Polyvalent Cations (Chelation) Eltrombopag chelates polyvalent cations (such as iron, calcium, aluminum, magnesium, selenium, and zinc) in foods, mineral supplements, and antacids. Take PROMACTA 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 PROMACTA due to chelation [see Dosage and Administration (2.4), Clinical Pharmacology (12.3)] .
7.2Transporters Use caution when concomitantly administering PROMACTA 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 PROMACTA, a dose reduction of rosuvastatin by 50% was recommended.
7.3Protease Inhibitors HIV Protease Inhibitors: No dose adjustment is recommended when PROMACTA is coadministered with lopinavir/ritonavir (LPV/RTV). Drug interactions with other HIV protease inhibitors have not been evaluated. Hepatitis C Virus Protease Inhibitors: No dose adjustments are recommended when PROMACTA is coadministered with boceprevir or telaprevir.
Drug interactions with other hepatitis C virus (HCV) protease inhibitors have not been evaluated.
7.4Peginterferon Alfa-2a/b Therapy No dose adjustments are recommended when PROMACTA is coadministered with peginterferon alfa-2a (PEGASYS ® ) or -2b (PEGINTRON ® ).
7.5Interference with Clinical Laboratory Tests Eltrombopag (PROMACTA) is highly colored and can cause patient sample discoloration, which is reported to interfere with some clinical laboratory tests, including, but not limited to bilirubin and creatinine. Bilirubin Testing : Eltrombopag can cause both positive and negative interference with bilirubin assays. If the laboratory results for bilirubin are inconsistent with clinical observations, further evaluation of liver function should be performed to clarify the clinical status of the patient.
Evaluating contemporaneous aminotransferase values (AST, ALT) may help determine the validity of normal total bilirubin levels in the presence of clinical jaundice. Creatinine Testing : Eltrombopag can cause positive interference with creatinine measurements, leading to falsely elevated creatinine levels. In the event of an unexpected serum creatinine test result, further evaluation of renal function should be performed.
Blood urea should be evaluated if serum creatinine is unexpectedly high. Communicate to the lab conducting testing if the patient is taking PROMACTA. Re-testing using other methods may also help in determining the validity of the test results.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Advise women not to breastfeed during treatment. ( 8.2 )
8.1Pregnancy Risk Summary Available data from a small number of published case reports and postmarketing experience with PROMACTA 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. These effects were observed at doses resulting in exposures that were six times the human clinical exposure based on area under the curve (AUC) in patients with persistent or chronic ITP at 75 mg/day, and three times the AUC in patients with chronic hepatitis C at 100 mg/day (see Data).
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and of miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Data Animal Data In an early embryonic development study, female rats received oral eltrombopag at doses of 10, 20, or 60 mg/kg/day (0.8, 2, and 6 times, respectively, the human clinical exposure based on AUC in patients with ITP at 75 mg/day and 0.3, 1, and 3 times, respectively, the human clinical exposure based on AUC in patients with chronic hepatitis C at 100 mg/day). Increased pre- and post-implantation loss and reduced fetal weight were observed at the highest dose which also caused maternal toxicity. In an embryo-fetal development study eltrombopag was administered orally to pregnant rats during the period of organogenesis at doses of 10, 20, or 60 mg/kg/day (0.8, 2, and 6 times, respectively, the human clinical exposure based on AUC in patients with ITP at 75 mg/day and 0.3, 1, and 3 times, respectively, the human clinical exposure based on AUC in patients with chronic hepatitis C at 100 mg/day).
Decreased fetal weights (6% to 7%) and a slight increase in the presence of cervical ribs were observed at the highest dose which also caused maternal toxicity. However, no evidence of major structural malformations was observed. In an embryo-fetal development study eltrombopag was administered orally to pregnant rabbits during the period of organogenesis at doses of 30, 80, or 150 mg/kg/day (0.04, 0.3, and 0.5 times, respectively, the human clinical exposure based on AUC in patients with ITP at 75 mg/day and 0.02, 0.1, and 0.3 times, respectively, the human clinical exposure based on AUC in patients with chronic hepatitis C at 100 mg/day).
No evidence of fetotoxicity, embryolethality, or teratogenicity was observed. In a pre- and post-natal developmental toxicity study in pregnant rats (F0), oral eltrombopag was administered from gestation Day 6 through lactation Day 20. No adverse effects on maternal reproductive function or on the development of the offspring (F1) were observed at doses up to 20 mg/kg/day (2 times the human clinical exposure based on AUC in patients with ITP at 75 mg/day and similar to the human clinical exposure based on AUC in patients with chronic hepatitis C at 100 mg/day).
Eltrombopag was detected in the plasma of offspring (F1). The plasma concentrations in pups increased with dose following administration of drug to the F0 dams.
8.2Lactation Risk Summary There are no data regarding the presence of eltrombopag or its metabolites in human milk, the effects on the breastfed child, or the effects on milk production. However, eltrombopag was detected in the pups of lactating rats 10 days postpartum suggesting the potential for transfer during lactation. Due to the potential for serious adverse reactions in a breastfed child from PROMACTA, breastfeeding is not reco…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and efficacy of PROMACTA have been established in pediatric patients 1 year and older with persistent or chronic ITP and in pediatric patients 2 years and older with IST-naïve severe aplastic anemia (in combination with h-ATG and cyclosporine). Safety and efficacy in pediatric patients below the age of 1 year with ITP have not been established. Safety and efficacy in pediatric patients with thrombocytopenia associated with chronic hepatitis C and refractory severe aplastic anemia have not been established.
The safety and efficacy of PROMACTA in pediatric patients 1 year and older with persistent or chronic ITP were evaluated in two double-blind, placebo-controlled trials [see Adverse Reactions (6.1), Clinical Studies (14.1)] . The pharmacokinetics of eltrombopag have been evaluated in 168 pediatric patients 1 year and older with ITP dosed once daily [see Clinical Pharmacology (12.3)] . See Dosage and Administration (2.1) for dosing recommendations for pediatric patients 1 year and older.
The safety and efficacy of PROMACTA in combination with h-ATG and cyclosporine for the first-line treatment of severe aplastic anemia in pediatric patients 2 years and older were evaluated in a single-arm, open-label trial [see Adverse Reactions (6.1), Clinical Studies (14.3)] . A total of 26 pediatric patients (ages 2 to < 17 years) were evaluated; 12 children (aged 2 to < 12 years) and 14 adolescents (aged 12 to < 17). See Dosage and Administration (2.3) for dosing recommendations for pediatric patients 2 years and older.
The safety and efficacy of PROMACTA in combination with h-ATG and cyclosporine in pediatric patients younger than 2 years for the first-line treatment of severe aplastic anemia have not yet been established. In patients 2 to 16 years of age, 69% of patients experienced serious adverse events compared to 42% in patients 17 years and older. Among the 12 patients who were 2 to 11 years of age in the PROMACTA D1-M6 cohort and reached the 6-month assessment or withdrew earlier, the complete response rate at Month 6 was 8% versus 46% in patients age 12 to 16 years and 50% in patients 17 years of age and older.
🧓 Geriatric Use ▾
8.5Geriatric Use Of the 106 patients in two randomized clinical trials of PROMACTA 50 mg in persistent or chronic ITP, 22% were 65 years of age and over, while 9% were 75 years of age and over. Of the 1439 patients in two randomized clinical trials of PROMACTA in patients with chronic hepatitis C and thrombocytopenia, 7% were 65 years of age and over, while < 1% were 75 years of age and over. Of the 196 patients who received PROMACTA for the treatment of severe aplastic anemia, 18% were 65 years of age and over, while 3% were 75 years of age and over.
No overall differences in safety or effectiveness were observed between these patients and younger patients.
🆘 Overdosage ▾
10 OVERDOSAGE In the event of overdose, platelet counts may increase excessively and result in thrombotic/thromboembolic complications. In one report, a subject who ingested 5000 mg of PROMACTA had a platelet count increase to a maximum of 929 x 10 9 /L at 13 days following the ingestion. The patient also experienced rash, bradycardia, ALT/AST elevations, and fatigue.
The patient was treated with gastric lavage, oral lactulose, intravenous fluids, omeprazole, atropine, furosemide, calcium, dexamethasone, and plasmapheresis; however, the abnormal platelet count and liver test abnormalities persisted for 3 weeks. After 2 months’ follow-up, all events had resolved without sequelae. In case of an overdose, consider oral administration of a metal cation-containing preparation, such as calcium, aluminum, or magnesium preparations to chelate eltrombopag and thus limit absorption.
Closely monitor platelet counts. Reinitiate treatment with PROMACTA in accordance with dosing and administration recommendations [see Dosage and Administration (2.1, 2.2)] . Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Eltrombopag is a TPO-receptor agonist that interacts with the transmembrane domain of the human TPO-receptor (also known as cMpl) and initiates signaling cascades that induce proliferation and differentiation of megakaryocytes leading to increased platelet production.
12.2Pharmacodynamics In clinical trials, treatment with PROMACTA resulted in dose-dependent increases in platelet counts following repeated (daily) dosing. The increase in platelet counts reached a maximum approximately two weeks after the initiation of dosing, and returned to baseline within approximately two weeks after the last dose of PROMACTA. Cardiac Electrophysiology At doses up to 150 mg (the maximum recommended dose) daily for 5 days, PROMACTA did not prolong the QT/QTc interval to any relevant extent.
12.3Pharmacokinetics Eltrombopag demonstrated a dose-proportional increase in exposure between doses of 50 to 150 mg/day in healthy adult subjects. Eltrombopag AUC was approximately 1.7-fold higher in patients with persistent or chronic ITP and approximately 2.8-fold higher in patients with HCV compared to healthy subjects. Steady-state was achieved after approximately 1 week of once daily treatment, with geometric mean accumulation ratio of 1.56 (90% confidence interval 1.20, 1.63) at 75 mg/day.
Eltrombopag AUC was approximately 3.2-fold higher in patients with definitive immunosuppressive therapy-naïve severe aplastic anemia compared to healthy subjects suggesting higher relative exposure compared to healthy subjects or patients with ITP and similar exposure compared to patients with chronic hepatitis C. Eltrombopag for oral suspension delivered 22% higher plasma AUC 0-INF than the tablet formulation. Absorption Eltrombopag is absorbed with a peak concentration occurring 2 to 6 hours after oral administration.
Oral absorption of drug-related material following administration of a single 75-mg solution dose was estimated to be at least 52%. Effect of Food A standard high-fat breakfast (876 calories, 52 g fat, 71 g carbohydrate, 34 g protein, and 427 mg calcium) significantly decreased plasma eltrombopag AUC 0-INF by approximately 59% and C max by 65% and delayed T max by 1 hour. The decrease in exposure is primarily due to the high calcium content.
A meal low in calcium (≤ 50 mg calcium) did not significantly impact plasma eltrombopag exposure, regardless of calorie and fat content. The effect of administration of a single 25-mg dose of eltrombopag for oral suspension with a high-calcium, moderate-fat, moderate calorie meal on AUC 0-INF and C max in healthy adult subjects is presented in Table 14. Table 14.
Effect on Plasma Eltrombopag Pharmacokinetic Parameters After Administration of a Single 25-mg Dose of Eltrombopag for Oral Suspension With a High Calcium Meal a in Healthy Adult Subjects a 372 calories, 9 g fat, and 448 mg calcium. Timing of eltrombopag for oral suspension dose Mean (90% CI) reduction in plasma eltrombopag AUC 0-INF Mean (90% CI) reduction in plasma eltrombopag C max With a high-calcium, moderate-fat, moderate-calorie meal 75% (71%, 88%) 79% (76%, 82%) 2 hours after the high-calcium, moderate-fat, moderate-calorie meal 47% (40%, 53%) 48% (40%, 54%) 2 hours before the high-calcium, moderate-fat, moderate-calorie meal 20% (9%, 29%) 14% (2%, 25%) Distribution The concentration of eltrombopag in blood cells is approximately 50% to 79% of plasma concentrations based on a radiolabel study.
In vitro studies suggest that eltrombopag is highly bound to human plasma proteins (greater than 99%). Eltrombopag is a substrate of BCRP, but is not a substrate for P-glycoprotein (P-gp) or OATP1B1. Elimination The plasma elimination half-life of eltrombopag is approximately 21 to 32 hours in healthy subjects and 26 to 35 hours in patients with ITP.
Metabolism: Absorbed eltrombopag is extensively metabolized, predominantly through pathways, including cleavage, oxidation, and conjugation with glucuronic…

PROMACTA can cause serious side effects, including: Liver problems: If you have chronic hepatitis C virus and take PROMACTA with interferon and ribavirin treatment, PROMACTA may increase your risk of liver problems.
If your healthcare provider tells you to stop your treatment with interferon and ribavirin, you will also need to stop taking PROMACTA. PROMACTA may increase your risk of liver problems that may be severe and possibly life threatening. Your healthcare provider will do blood tests to check your liver function before you start taking PROMACTA and during your treatment.
Your healthcare provider may stop your treatment with PROMACTA if you have changes in your liver function blood tests. Tell your healthcare provider right away if you have any of these signs and symptoms of liver problems: yellowing of the skin or the whites of the eyes (jaundice) unusual darkening of the urine unusual tiredness right upper stomach area (abdomen) pain confusion swelling of the stomach area (abdomen) See “What are the possible side effects of PROMACTA?” for other side effects of PROMACTA. What is PROMACTA?
PROMACTA is a prescription medicine used to treat adults and children 1 year of age and older with low blood platelet counts due to persistent or chronic immune thrombocytopenia (ITP), when other medicines to treat ITP or surgery to remove the spleen have not worked well enough. PROMACTA is also used to treat people with: low blood platelet counts due to chronic hepatitis C virus (HCV) infection before and during treatment with interferon. severe aplastic anemia (SAA) in combination with other medicines to treat SAA, as the first treatment for adults and children 2 years of age and older. severe aplastic anemia (SAA) when other medicines to treat SAA have not worked well enough.
PROMACTA is used to try to raise platelet counts in order to lower your risk for bleeding. PROMACTA is not used to make platelet counts normal. PROMACTA is not for use in people with a pre-cancerous condition called myelodysplastic syndrome (MDS), or in people with low platelet counts caused by certain other medical conditions or diseases.
It is not known if PROMACTA is safe and effective when used with other antiviral medicines to treat chronic hepatitis C. It is not known if PROMACTA is safe and effective in children: younger than 1 year with ITP with low blood platelet counts due to chronic hepatitis C whose severe aplastic anemia (SAA) has not improved after previous treatments younger than 2 years when used in combination with other medicines to treat SAA as the first treatment for SAA Before you take PROMACTA, tell your healthcare provider about all of your medical conditions, including if you: have liver problems have a precancerous condition called MDS or a blood cancer have or had a blood clot have a history of cataracts have had surgery to remove your spleen (splenectomy) have bleeding problems are of East-/Southeast-Asian ancestry.
You may need a lower dose of PROMACTA are pregnant or plan to become pregnant. It is not known if PROMACTA will harm an unborn baby. Tell your healthcare provider if you become pregnant or think you may be pregnant during treatment with PROMACTA.
Females who are able to become pregnant, should use effective birth control (contraception) during treatment with PROMACTA and for at least 7 days after stopping treatment with PROMACTA.
