Generic Name: lomitapide (loe-MI-ta-pide)
Lomitapide mesylate can cause elevations in transaminases. Measure ALT, AST, alkaline phosphatase, and total bilirubin before initiating treatment and then ALT and AST regularly as recommended. During treatment, adjust the dose of lomitapide mesylate if the ALT or AST is 3 times the ULN or greater. Discontinue lomitapide mesylate for clinically significant liver toxicity. Lomitapide mesylate increases hepatic fat (hepatic steatosis) with or without concomitant increases in transaminases. Hepatic steatosis associated with lomitapide mesylate may be a risk factor for progressive liver disease, including steatohepatitis and cirrhosis. Because of the risk of hepatotoxicity, lomitapide mesylate is available only through a restricted program called the Juxtapid(R) REMS Program. Prescribe lomitapide mesylate only to patients with a clinical or laboratory diagnosis consistent with homozygous familial hypercholesterolemia (HoFH). The safety and effectiveness of lomitapide mesylate have not been established in patients with hypercholesterolemia who do not have HoFH .
