id="_BempedoicAcid_OVERVIEW_">OVERVIEW</h2><div id="BempedoicAcid.Introduction"><h3>Introduction</h3><p>Bempedoic acid is a small molecule inhibitor of adenosine triphosphate-citrate lyase that is used as a cholesterol lowering agent in patients with hypercholesterolemia and high risk or with known atherosclerotic cardiovascular disease who fail to have an adequate response or are intolerant of conventional statin therapy. Bempedoic acid is associated with a low rate of mild, asymptomatic and self-limited serum aminotransferase elevations during therapy and to rare instances of clinically apparent acute liver injury.</p></div><div id="BempedoicAcid.Background"><h3>Background</h3><p>Bempedoic (bem&#x0201d; pe doe&#x02019; ik) acid is an orally available, small molecule inhibitor of adenosine triphosphate-citrate lyase (ACL), a hepatic enzyme involved in cholesterol synthesis. Inhibition of ACL results in a lowering of intrahepatic cholesterol levels which leads to an increase in LDL cholesterol (LDL-C) receptors on hepatocytes and increased uptake of LDL-C from serum resulting in lower serum levels. In large, randomized placebo-controlled trials, bempedoic acid resulted in a 17% to 24% decrease in LDL cholesterol levels. Bempedoic acid was approved for use in the United States in 2020 as an adjunct to diet and statins for control of LDL cholesterol levels in patients with heterozygous familial hypercholesterolemia or patients with established atherosclerotic cardiovascular disease who fail to have an adequate response or are intolerant of conventional statin therapy. Bempedoic acid has been shown to decrease the risk of morbidity and mortality from atherosclerotic cardiovascular disease but with less efficacy than statins, for which reason it is generally reserved for patients who have an inadequate response to maximal tolerated doses of statins. Bempedoic acid is available under the brand name Nexletol in tablets of 180 mg and the recommended dose is 180 mg once daily. Common side effects include symptoms of upper respiratory infection, muscle cramps and pain, back pain, abdominal pain, hyperuricemia, bronchitis, headache, nausea, and weakness. Rare but potentially severe adverse events include severe hyperuricemia and tendon rupture.</p></div><div id="BempedoicAcid.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>Bempedoic acid is associated with low rate of mild, asymptomatic and typically transient serum aminotransferase elevations during therapy. In prelicensure controlled trials, elevations in either ALT or AST arose in 2% of treated patients compared to less than 1% of placebo recipients. ALT elevations above 3 times the upper limit of normal (ULN) arise in less than 1% of bempedoic treated patients, a rate similar to that in placebo recipients (most of the participants were taking other cholesterol lowering agents such as statins or ezetimibe). There were no instances of serum ALT elevations associated with symptoms or jaundice in the prelicensure trials. Since the approval and more widespread use of bempedoic acid, there have been no published reports of clinically apparent liver injury attributed to its use.</p><p>Likelihood score: E (unlikely cause of clinically apparent liver injury).</p></div><div id="BempedoicAcid.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The potential cause of hepatic injury from bempedoic acid is unknown. It is metabolized in the liver (via CYP 2C9). The mild, self-limited ALT elevations may be due to a toxic intermediate of drug metabolism and the reversal of these elevations due to adaptation.</p></div><div id="BempedoicAcid.Outcome_and_Management"><h3>Outcome and Management</h3><p>The serum enzyme elevations that sometimes arise in patients taking bempedoic acid generally resolve even without dose modification or discontinuation. There is no evidence for cross sensitivity to hepatic injury among the various cholesterol lowering drugs.</p><p>Drug Class: <a href="/books/n/livertox/Lipid-LoweringAgents/?report=reader">Antilipemic Agents</a></p><p>Other Drugs in the Subclass, <a href="/books/n/livertox/Statins/?report=reader">Statins</a>: <a href="/books/n/livertox/Atorvastatin/?report=reader">Atorvastatin</a>, <a href="/books/n/livertox/Ezetimibe/?report=reader">Ezetimibe [used in combination]</a></p></div></div><div id="BempedoicAcid.PRODUCT_INFORMATION"><h2 id="_BempedoicAcid_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
