Disease interactions

8 potential interactions Applies to: 7 conditions, including Cataract, Thrombotic/Thromboembolic Disorder, Liver Disease, Renal Dysfunction, and History, Thrombotic/Thromboembolic Disorder.

Cataract

Moderate:

Promacta Kit

The eltrombopag in Promacta Kit has a moderate potential interaction with Cataract.

In clinical trials, eltrombopag developed or worsened cataracts in 7% of the patients receiving treatment. A baseline ocular examination prior to administration of eltrombopag is recommended, and regular monitoring for signs and symptoms of cataracts should be performed regularly during treatment.

History, Thrombotic/Thromboembolic Disorder

Moderate:

Promacta Kit

The eltrombopag in Promacta Kit has a moderate potential interaction with History, Thrombotic/Thromboembolic Disorder.

Thromboembolic complications may result from increases in platelet counts with TPO receptor agonists such as avatrombopag, lusutrombopag, and eltrombopag. Consider the potential for increased risk of thromboembolism when administering these medications to patients with known risk factors for thromboembolism, including genetic prothrombotic conditions (Factor V Leiden, Prothrombin 20210 A, Antithrombin deficiency or Protein C or S deficiency).

Infectious Hepatitis

Major:

Promacta Kit

The eltrombopag in Promacta Kit has a major potential interaction with Infectious Hepatitis.

Eltrombopag has shown to increase the risk of hepatic decompensation in patients with chronic hepatitis C in treatment with interferon and ribavirin. Clinical trials reported that ascites and encephalopathy occurred more frequently on these patients than in the placebo arm. Patients with chronic hepatitis and receiving antiviral treatment should be closely monitored. The manufacturers also recommend to discontinue eltrombopag if the antiviral therapy is discontinued.

Liver Disease

Major:

Promacta Kit

The eltrombopag in Promacta Kit has a major potential interaction with Liver Disease.

Eltrombopag can cause liver enzyme elevations. Monitor ALT, AST and bilirubin prior to treatment initiation, and every 2 weeks during dose adjustment phase and then monthly. If abnormalities are confirmed, monitor serum liver tests weekly until resolved or stabilized. Treatment should be discontinued if ALT levels increase to greater than or equal to 3 x ULN in patients with normal liver function, or greater or equal to 3 x baseline in patients with pretreatment transaminase elevations that are progressively increasing, persist for 4 weeks or more, also have an increase in bilirubin, or also have clinical symptoms of liver injury or hepatic decompensation.

Hepatic impairment influences the exposure to eltrombopag. The initial dose should be reduced in patients with chronic ITP or severe aplastic anemia who have hepatic impairment. No dose adjustment is required on patients with chronic hepatitis C and hepatic impairment.

Moderate:

maribavir

Maribavir has a moderate potential interaction with Liver Disease.

No dose adjustment of maribavir is required in patients with mild (Child-Pugh A) or moderate (Child-Pugh B) liver dysfunction. Maribavir has not been studied in patients with severe liver dysfunction; caution is recommended.

Protein C Deficiency

Moderate:

Promacta Kit

The eltrombopag in Promacta Kit has a moderate potential interaction with Protein C Deficiency.

Thromboembolic complications may result from increases in platelet counts with TPO receptor agonists such as avatrombopag, lusutrombopag, and eltrombopag. Consider the potential for increased risk of thromboembolism when administering these medications to patients with known risk factors for thromboembolism, including genetic prothrombotic conditions (Factor V Leiden, Prothrombin 20210 A, Antithrombin deficiency or Protein C or S deficiency).

Renal Dysfunction

Moderate:

maribavir

Maribavir has a moderate potential interaction with Renal Dysfunction.

No dose adjustment of maribavir is required in patients with mild, moderate, or severe renal dysfunction. Maribavir has not been studied in patients with end-stage renal disease, including those on dialysis; caution is recommended.

Thrombotic/Thromboembolic Disorder

Moderate:

Promacta Kit

The eltrombopag in Promacta Kit has a moderate potential interaction with Thrombotic/Thromboembolic Disorder.

Thromboembolic complications may result from increases in platelet counts with TPO receptor agonists such as avatrombopag, lusutrombopag, and eltrombopag. Consider the potential for increased risk of thromboembolism when administering these medications to patients with known risk factors for thromboembolism, including genetic prothrombotic conditions (Factor V Leiden, Prothrombin 20210 A, Antithrombin deficiency or Protein C or S deficiency).
