    CONTRAINDICATIONS / PRECAUTIONS

    Fish hypersensitivity

    Icosapent ethyl contains ethyl esters of the omega-3 fatty acid, eicosapentaenoic acid (EPA), obtained from the oil of fish. According to the manufacturer, it is unknown whether patients with fish hypersensitivity are at increased risk of an allergic reaction to icosapent ethyl. Therefore, the drug should be used with caution in patients with known hypersensitivity to fish and/or shellfish.

    Anticoagulant therapy, bleeding, thrombolytic therapy

    Because omega-3 fatty acids inhibit platelet aggregation, bleeding time may be prolonged in patients receiving icosapent ethyl. In published studies with omega-3 fatty acids, the prolongation of bleeding time did not exceed normal limits and no clinically significant bleeding episodes were reported. However, caution is advised when icosapent ethyl is used concurrently with anticoagulant therapy or thrombolytic therapy.

    Pregnancy

    Icosapent ethyl is classified in FDA pregnancy risk category C. There are no adequate and well-controlled studies in pregnant women. According to the manufacturer, it is not known whether administration of icosapent ethyl during pregnancy can cause fetal harm or affect reproductive capacity. Therefore, icosapent ethyl should only be administered during pregnancy if the potential benefit justifies the potential risk to the fetus.

    Breast-feeding

    According to the manufacturer, omega-3-acid ethyl esters are excreted in human milk; however, the effect of this excretion is unknown. During breast-feeding, omega-3 fatty acids do not appear to be harmful to the infant at levels approximating normal maternal dietary intakes (i.e., via fish in the maternal diet). Until more data are available, caution should be exercised when icosapent ethyl is administered to a nursing mother.

    Children, infants, neonates

    The safety and efficacy of icosapent ethyl have not been established in neonates, infants, children, or adolescents.

    Hepatic disease

    Monitor alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels periodically in patients with hepatic disease who are receiving icosapent ethyl.

    DRUG INTERACTIONS

    Abciximab: (Moderate) Icosapent ethyl is an ethyl ester of the omega-3 fatty acid eicosapentaenoic acid (EPA). Because omega-3 fatty acids inhibit platelet aggregation, caution is advised when icosapent ethyl is used concurrently with anticoagulants, platelet inhibitors, or thrombolytic agents. Theoretically, the risk of bleeding may be increased, but some studies that combined these agents did not produce clinically significant bleeding events. In one placebo-controlled, randomized, double-blinded, parallel study, patients receiving stable, chronic warfarin therapy were administered various doses of fish oil supplements to determine the effect on INR determinations. Patients were randomized to receive a 4-week treatment period of either placebo or 3 or 6 grams of fish oil daily. Patients were followed on a twice-weekly basis for INR determinations and adverse reactions. There was no statistically significant difference in INRs between the placebo or treatment period within each group. There was also no difference in INRs found between groups. One episode of ecchymosis was reported, but no major bleeding episodes occurred. The authors concluded that fish oil supplementation in doses of 36 grams per day does not have a statistically significant effect on the INR of patients receiving chronic warfarin therapy. However, an increase in INR from 2.8 to 4.3 in a patient stable on warfarin therapy has been reported when increasing the dose of fish oil, omega-3 fatty acids from 1 gram/day to 2 grams/day. The INR decreased once the patient decreased her dose of fish oil to 1 gram/day. This implies that a dose-related effect of fish oil on warfarin may be possible. Patients receiving warfarin that initiate concomitant icosapent ethyl therapy should have their INR monitored more closely and the dose of warfarin adjusted accordingly.

However, an increase in INR from 2.8 to 4.3 in a patient stable on warfarin therapy has been reported when increasing the dose of fish oil, omega-3 fatty acids from 1 gram/day to 2 grams/day. The INR decreased once the patient decreased her dose of fish oil to 1 gram/day. This implies that a dose-related effect of fish oil on warfarin may be possible. Patients receiving warfarin that initiate concomitant icosapent ethyl therapy should have their INR monitored more closely and the dose of warfarin adjusted accordingly.
    Danaparoid: (Moderate) Icosapent ethyl is an ethyl ester of the omega-3 fatty acid eicosapentaenoic acid (EPA). Because omega-3 fatty acids inhibit platelet aggregation, caution is advised when icosapent ethyl is used concurrently with anticoagulants, platelet inhibitors, or thrombolytic agents. Theoretically, the risk of bleeding may be increased, but some studies that combined these agents did not produce clinically significant bleeding events. In one placebo-controlled, randomized, double-blinded, parallel study, patients receiving stable, chronic warfarin therapy were administered various doses of fish oil supplements to determine the effect on INR determinations. Patients were randomized to receive a 4-week treatment period of either placebo or 3 or 6 grams of fish oil daily. Patients were followed on a twice-weekly basis for INR determinations and adverse reactions. There was no statistically significant difference in INRs between the placebo or treatment period within each group. There was also no difference in INRs found between groups.

Because omega-3 fatty acids inhibit platelet aggregation, caution is advised when icosapent ethyl is used concurrently with anticoagulants, platelet inhibitors, or thrombolytic agents. Theoretically, the risk of bleeding may be increased, but some studies that combined these agents did not produce clinically significant bleeding events. In one placebo-controlled, randomized, double-blinded, parallel study, patients receiving stable, chronic warfarin therapy were administered various doses of fish oil supplements to determine the effect on INR determinations. Patients were randomized to receive a 4-week treatment period of either placebo or 3 or 6 grams of fish oil daily. Patients were followed on a twice-weekly basis for INR determinations and adverse reactions. There was no statistically significant difference in INRs between the placebo or treatment period within each group. There was also no difference in INRs found between groups. One episode of ecchymosis was reported, but no major bleeding episodes occurred. The authors concluded that fish oil supplementation in doses of 36 grams per day does not have a statistically significant effect on the INR of patients receiving chronic warfarin therapy. However, an increase in INR from 2.8 to 4.3 in a patient stable on warfarin therapy has been reported when increasing the dose of fish oil, omega-3 fatty acids from 1 gram/day to 2 grams/day. The INR decreased once the patient decreased her dose of fish oil to 1 gram/day. This implies that a dose-related effect of fish oil on warfarin may be possible. Patients receiving warfarin that initiate concomitant icosapent ethyl therapy should have their INR monitored more closely and the dose of warfarin adjusted accordingly.

    PREGNANCY AND LACTATION

    Pregnancy

    Icosapent ethyl is classified in FDA pregnancy risk category C. There are no adequate and well-controlled studies in pregnant women. According to the manufacturer, it is not known whether administration of icosapent ethyl during pregnancy can cause fetal harm or affect reproductive capacity. Therefore, icosapent ethyl should only be administered during pregnancy if the potential benefit justifies the potential risk to the fetus.

    According to the manufacturer, omega-3-acid ethyl esters are excreted in human milk; however, the effect of this excretion is unknown. During breast-feeding, omega-3 fatty acids do not appear to be harmful to the infant at levels approximating normal maternal dietary intakes (i.e., via fish in the maternal diet). Until more data are available, caution should be exercised when icosapent ethyl is administered to a nursing mother.

    MECHANISM OF ACTION

    Icosapent ethyl is an ethyl ester of eicosapentaenoic acid (EPA). EPA is thought to inhibit hepatic very low-density lipoprotein (VLDL) triglycerides synthesis and/or secretion and enhance the clearance of triglycerides from circulating VLDL particles. Other potential mechanisms of action include increased beta-oxidation, inhibition of acyl-CoA:1,2-diacylglycerol acyltransferase (DGAT), decreased hepatic lipogenesis, and increased plasma lipoprotein lipase activity.

    PHARMACOKINETICS

    Icosapent ethyl is administered orally. Icosapent ethyl is de-esterified during absorption to the active metabolite eicosapentaenoic acid (EPA). The majority of EPA circulating in plasma is incorporated in phospholipids, triglycerides and cholesteryl esters, and < 1% is present as the unesterified fatty acid. Unesterified EPA is > 99% bound to plasma proteins. Like dietary fatty acids, EPA is metabolized mainly by the liver via beta-oxidation. Cytochrome P450-mediated metabolism is a minor elimination pathway of EPA. Icosapent ethyl does not undergo renal elimination. The plasma-elimination half-life of EPA is approximately 89 hours.

    Oral Route

    After oral administration of icosapent ethyl, peak plasma concentrations of EPA are reached in approximately 5 hours. The effect of food on the absorption of icosapent ethyl has not been studied. In all clinical studies, the drug was administered with or following a meal, and therefore, it is recommended that icosapent ethyl be given with food or following a meal.
