Disease interactions

9 potential interactions Applies to: 9 conditions, including Heart Failure, Seizures, Anemia, Head Injury, and Liver Disease.

Anemia

Moderate:

macitentan

Macitentan has a moderate potential interaction with Anemia.

Clinical studies have shown that most endothelin receptor antagonists decrease hemoglobin concentration and hematocrit levels. There are some postmarketing reports of anemia cases which needed blood transfusion. Hemoglobin and hematocrit levels should be measured prior to treatment initiation and should be monitored periodically thereafter. Initiation of therapy is not recommended in patients with clinically significant anemia.

Brain Tumor

Moderate:

enzalutamide

Enzalutamide has a moderate potential interaction with Brain Tumor.

Seizures occurred in 0.5% of patients receiving enzalutamide in clinical trials. Patients with predisposing factors for seizures were generally excluded. Caution is advised if using in patients with possible predisposing factors such as history of seizures, history of trauma or head injury, cerebrovascular accident or transient ischemic attack, Alzheimer's disease, meningioma or brain tumor or infection, and any unexplained loss of consciousness in the past 12 months. Enzalutamide should be discontinued permanently in any patient who develops a seizure during treatment.

CNS Infection

Moderate:

enzalutamide

Enzalutamide has a moderate potential interaction with CNS Infection.

Seizures occurred in 0.5% of patients receiving enzalutamide in clinical trials. Patients with predisposing factors for seizures were generally excluded. Caution is advised if using in patients with possible predisposing factors such as history of seizures, history of trauma or head injury, cerebrovascular accident or transient ischemic attack, Alzheimer's disease, meningioma or brain tumor or infection, and any unexplained loss of consciousness in the past 12 months. Enzalutamide should be discontinued permanently in any patient who develops a seizure during treatment.

Head Injury

Moderate:

enzalutamide

Enzalutamide has a moderate potential interaction with Head Injury.

Seizures occurred in 0.5% of patients receiving enzalutamide in clinical trials. Patients with predisposing factors for seizures were generally excluded. Caution is advised if using in patients with possible predisposing factors such as history of seizures, history of trauma or head injury, cerebrovascular accident or transient ischemic attack, Alzheimer's disease, meningioma or brain tumor or infection, and any unexplained loss of consciousness in the past 12 months. Enzalutamide should be discontinued permanently in any patient who develops a seizure during treatment.

Heart Failure

Moderate:

macitentan

Macitentan has a moderate potential interaction with Heart Failure.

Peripheral edema and fluid retention are known clinical consequences of pulmonary hypertension and also known effects of endothelin receptor antagonists. Caution and monitoring is recommended if these agents are used in patients with underlying left ventricular dysfunction or underlying heart failure, as they have an increased risk for developing significant fluid retention that may need treatment or require discontinuation.

History - Cerebrovascular Disease

Moderate:

enzalutamide

Enzalutamide has a moderate potential interaction with History - Cerebrovascular Disease.

Seizures occurred in 0.5% of patients receiving enzalutamide in clinical trials. Patients with predisposing factors for seizures were generally excluded. Caution is advised if using in patients with possible predisposing factors such as history of seizures, history of trauma or head injury, cerebrovascular accident or transient ischemic attack, Alzheimer's disease, meningioma or brain tumor or infection, and any unexplained loss of consciousness in the past 12 months. Enzalutamide should be discontinued permanently in any patient who develops a seizure during treatment.

Liver Disease

Major:

macitentan

Macitentan has a major potential interaction with Liver Disease.

Endothelin receptor antagonists (ERAs) have been associated with aminotransferase elevations, hepatotoxicity, and cases of liver failure. Hepatic function should be assessed before treatment initiation and closely monitored during treatment. Therapy should be discontinued if aminotransferase elevations are accompanied by increases in bilirubin, or clinical symptoms of hepatotoxicity such as nausea, vomiting, fever, abdominal pain or jaundice. Treatment should be avoided in patients with elevated aminotransferases at baseline as monitoring for hepatotoxicity may be more difficult. In general, the use of ERAs is not recommended for patients with moderate to severe hepatic impairment.

Renal Dysfunction

Moderate:

enzalutamide

Enzalutamide has a moderate potential interaction with Renal Dysfunction.

Enzalutamide has not been assessed in patients with severe renal impairment or end-stage renal disease. Caution is advised if used on these patients. No initial dosage adjustment is required on patients with mild to moderate renal impairment.

Seizures

Moderate:

enzalutamide

Enzalutamide has a moderate potential interaction with Seizures.

Seizures occurred in 0.5% of patients receiving enzalutamide in clinical trials. Patients with predisposing factors for seizures were generally excluded. Caution is advised if using in patients with possible predisposing factors such as history of seizures, history of trauma or head injury, cerebrovascular accident or transient ischemic attack, Alzheimer's disease, meningioma or brain tumor or infection, and any unexplained loss of consciousness in the past 12 months. Enzalutamide should be discontinued permanently in any patient who develops a seizure during treatment.
