Interactions between your drugs

Major

omacetaxine betrixaban

Applies to: Synribo (omacetaxine) and betrixaban

GENERALLY AVOID: Coadministration of omacetaxine and drugs that interfere with platelet function or coagulation may potentiate the risk of bleeding complications. Treatment with omacetaxine is associated with a high frequency of thrombocytopenia. In one study, the overall incidence of grade 3 and 4 thrombocytopenia was 85% and 88%. Fatal cerebral hemorrhages occurred in 2% of patients receiving omacetaxine and nonfatal gastrointestinal hemorrhages occurred in 2%.

MANAGEMENT: Concomitant use of other medications that interfere with platelet function or coagulation should be avoided if the patient's platelet count is less than 50,000 per microliter. Close clinical and laboratory observation for bleeding complications is recommended during therapy. The CBC and platelet count should be monitored according to the manufacturer's recommendations. Patients should be advised to immediately report signs of hemorrhage including unusual bleeding, bruising, blood in the urine or feces, confusion, blurry vision, or slurred speech.

Drug and food interactions

Moderate

betrixaban food

Applies to: betrixaban

ADJUST DOSING INTERVAL: Food reduces the oral bioavailability of betrixaban. When administered with a low-fat (900 calories; 20% fat) or high-fat (900 calories; 60% fat) meal, betrixaban peak plasma concentration (Cmax) and systemic exposure (AUC) decreased relative to administration in the fasting state by an average of 70% and 61%, respectively, with the low-fat meal and 50% and 48%, respectively, with the high-fat meal. The effect of food on betrixaban pharmacokinetics could be observed for up to 6 hours after meal intake.

MANAGEMENT: The manufacturer recommends taking betrixaban at the same time each day with food.

Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
