Overview of prescription omega-3 fatty acid products for hypertriglyceridemia.

Prescription Omega-3 Fatty Acids and Their Lipid …



In preregistration clinical trials in patients with hypertriglyceridemia, liver test abnormalities were no more frequent among patients receiving omega-3 carboxylic acids than in those on placebo, and there were no reports of clinically apparent liver injury. In a pooled analysis of studies, mild elevations in ALT (up to 2 times the upper limit of normal) occurred in less than 1% of omega-3 carboxylic acid treated subjects and a similar proportion of those on placebo. There were no elevations above 5 times the upper limit of normal and no patient developed jaundice or symptoms and the abnormalities apparently resolved without dose adjustment. Since its approval and more widespread clinical use, there have been no published reports of hepatotoxicity attributable to Epanova. Nevertheless, the product labels of all prescription omega-3 fatty acid products recommend monitoring aminotransferase levels in patients with pre-existing hepatic impairment.

(Among 42 patients with hypertriglyceridemia treated with omega-3 acid ethyl esters [4 g daily] or placebo for 4 months, triglyceride levels decreased by 45% with omega-3 fatty acid therapy vs no effect of placebo and there were no severe adverse events or discontinuations, and therapy had “no impact on any of the safety panel parameters measured, including…liver enzymes”).

An omega-3 polyunsaturated fatty acid concentrate administered for one year decreased triglycerides in simvastatin treated patients with coronary heart disease and persisting hypertriglyceridaemia.

In preregistration clinical trials in patients with hypertriglyceridemia, liver test abnormalities were no more frequent among patients receiving icosapent than in those on placebo, and there were no reports of clinically apparent liver injury. In a pooled analysis of studies, mild elevations in ALT (up to 2 times the upper limit of normal) occurred in 12.8% of icosapent- compared to 10.3% of placebo treated subjects. However, no patient developed jaundice or symptoms and the abnormalities apparently resolved without dose adjustment. Since its approval and more widespread clinical use, there have been no published reports of hepatotoxicity attributable to icosapent. Nevertheless, the product labels of all prescription omega-3 fatty acid products recommend monitoring aminotransferase levels in patients with preexisting hepatic impairment.

(Among 12,513 adults with cardiovascular risk factors treated with omega-3 fatty acids or placebo daily for a median of 5 years, there were no significant differences in rates of cardiovascular endpoints or death nor in adverse event rates; no mention of ALT levels or hepatotoxicity).

In preregistration clinical trials, omega-3 acid ethyl esters were associated with uncommon and mild increases in serum ALT levels without changes in alkaline phosphatase or bilirubin levels. These abnormalities were asymptomatic and transient, but led to a recommendation of monitoring routine liver tests periodically during therapy with Lovaza. Since approval and wide scale use of this product, however, there have been no reports of liver injury attributable to the omega-3 acid esters and subsequent trials of these products have not mentioned serum aminotransferase elevations or hepatotoxicity in discussions of adverse events. The product label now recommends monitoring ALT and AST levels periodically only in patients with preexisting hepatic impairment, a recommendation added to product labels of all prescription omega-3 fatty acids.
