Cholesterol management is crucial for reducing the risk of atherosclerotic cardiovascular disease (ASCVD). While statins are the gold standard for lowering low-density lipoprotein cholesterol (LDL-C), some patients cannot tolerate them due to adverse effects. This has led to the development and use of non-statin cholesterol-lowering medications, which offer alternative or adjunctive options for managing cholesterol levels.
Ezetimibe is a non-statin medication that inhibits the absorption of cholesterol in the small intestine. It is often used in combination with statins to enhance cholesterol-lowering effects. Studies have shown that ezetimibe provides additional cardiovascular protection when combined with statin therapy, although its cholesterol-lowering effect is modest when used alone . Ezetimibe is generally well-tolerated, with a favorable safety profile compared to statins, making it a viable option for patients who experience statin-associated muscle symptoms (SAMS) or other adverse effects .
Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, such as evolocumab and bococizumab, have emerged as potent non-statin options for lowering LDL-C. Clinical trials like the FOURIER and SPIRE studies have demonstrated their efficacy in significantly reducing cardiovascular events in patients with ASCVD . PCSK9 inhibitors are particularly beneficial for patients who do not achieve their cholesterol goals with statins alone or who are statin-intolerant. These medications have shown a good safety profile in long-term studies, making them a safe alternative for cholesterol management .
Bempedoic acid (BDA) is a newer non-statin medication that has shown promising results in pre-clinical and clinical trials. It works by inhibiting ATP citrate lyase, an enzyme involved in cholesterol synthesis. BDA has demonstrated efficacy in lowering LDL-C levels and has a favorable safety profile, making it a potential option for patients who cannot tolerate statins.
Inclisiran is a small interfering RNA (siRNA) therapy that targets PCSK9 mRNA, leading to reduced PCSK9 protein levels and lower LDL-C. Clinical trials have shown that inclisiran effectively lowers LDL-C with a good safety profile. Its unique mechanism and biannual dosing schedule offer a convenient and effective alternative for cholesterol management.
For patients who cannot tolerate statins, non-statin cholesterol medications such as ezetimibe, PCSK9 inhibitors, bempedoic acid, and inclisiran provide effective and safe alternatives. Ezetimibe and PCSK9 inhibitors have well-established safety profiles and efficacy, while newer options like bempedoic acid and inclisiran show promising results in clinical trials. These medications offer valuable options for achieving cholesterol goals and reducing cardiovascular risk in statin-intolerant patients.
