Interactions between Darolutamide and 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.

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).

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.

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.

Darolutamide has a moderate potential interaction with Liver Disease.

Patients with moderate hepatic impairment (Child-Pugh Class B) have a higher exposure to darolutamide and reduction of the dose is recommended (see manufacturer package insert for recommended dose). No dose reduction is needed for patients with mild hepatic impairment. The effect of severe hepatic impairment (Child-Pugh C) on darolutamide pharmacokinetics is unknown.

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).

Darolutamide has a moderate potential interaction with Renal Dysfunction.

Patients with severe renal impairment (eGFR 15-29 mL/min/1.73 m2) who are not receiving hemodialysis have a higher exposure to darolutamide and reduction of the dose is recommended (see manufacturer package insert for recommended dose). No dose reduction is needed for patients with mild or moderate renal impairment. The effect of end stage renal disease (eGFR <15 mL/min/1.73 m2) on darolutamide pharmacokinetics is unknown.

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).
