Lipid-lowering agent

The several classes of lipid lowering drugs may differ in both their impact on the cholesterol profile and adverse effects. For example, some may lower low density lipoprotein (LDL) levels more so than others, while others may preferentially increase high density lipoprotein (HDL). Clinically, the choice of an agent depends on the patient's cholesterol profile, [https://web.archive.org/web/20060511202743/http://hp2010.nhlbihin.net/atpiii/calculator.asp?usertype=prof cardiovascular risk], and the liver and kidney functions of the patient, evaluated against the balancing of risks and benefits of the medications. In the United States, this is guided by the evidence-based guideline most recently updated in 2018 by the American College of Cardiology & American Heart Association.{{cite journal|last1=Alenghat|first1=Francis J.|last2=Davis|first2=Andrew M.|title=Management of Blood Cholesterol|journal=JAMA|year=2019|issn=0098-7484|doi=10.1001/jama.2019.0015|pmid=30715135|volume=321|issue=8|pages=800–801|pmc=6679800}}

• Statins (HMG-CoA reductase inhibitors) are particularly well suited for lowering LDL, the cholesterol with the strongest links to vascular diseases. In studies using standard doses, statins have been found to lower LDL-C by 18% to 55%, depending on the specific statin being used. A risk exists of muscle damage (myopathy and rhabdomyolysis) with statins. Hypercholesterolemia is not a risk factor for mortality in persons older than 70 years and risks from statin drugs are more increased after age 85.{{Citation |author1 = AMDA – The Society for Post-Acute and Long-Term Care Medicine |author1-link = AMDA – The Society for Post-Acute and Long-Term Care Medicine |date = February 2014 |title = Ten Things Physicians and Patients Should Question |publisher = AMDA – The Society for Post-Acute and Long-Term Care Medicine |work = Choosing Wisely: an initiative of the ABIM Foundation |url = http://www.choosingwisely.org/doctor-patient-lists/amda/ |access-date = 20 April 2015}}.
• Fibrates are indicated for hypertriglyceridemia. Fibrates typically lower triglycerides by 20% to 50%. Level of the good cholesterol HDL is also increased. Fibrates may decrease LDL, though generally to a lesser degree than statins. Similar to statins, the risk of muscle damage exists.
• Nicotinic acid, like fibrates, is also well suited for lowering triglycerides by 20–50%. It may also lower LDL by 5–25% and increase HDL by 15–35%. Niacin may cause hyperglycemia and may also cause liver damage. The niacin derivative acipimox is also associated with a modest decrease in LDL. Introduced in 1955.
• Bile acid sequestrants (resins, e.g. cholestyramine) are particularly effective for lowering LDL-C by sequestering the cholesterol-containing bile acids released into the intestine and preventing their reabsorption from the intestine. It decreases LDL by 15–30% and raises HDL by 3–5%, with little effect on triglycerides, but can cause a slight increase. Bile acid sequestrants may cause gastrointestinal problems and may also reduce the absorption of other drugs and vitamins from the gut.
• Ezetimibe is a selective inhibitor of dietary cholesterol absorption.
• Lomitapide is a microsomal triglyceride transfer protein inhibitor.
• PCSK9 inhibitorsKoren MJ, Scott R, Kim JB et al Lancet 2012; 380:1995-2006Gugliano RP, Desai NR, Kohli P et al Lancet 2012; 380:2007-17 are monoclonal antibodies for refractory cases. (e.g. Evolocumab, Inclisiran) They are used in combination with statins.
• Probucol decreases LDL independently of the LDL receptor, and decreases HDL-C by enhancing its liver receptor and reducing ABCA1-dependent transport. The reduction of HDL-C, combined with early uncertainties around its mechanism of action, has historically lead to its discontinuation and replacement by statins in Western countries. However, instead of lowering reverse cholesterol transport by HDL particles, probucol seems to increase it. Introduced in the 1970s.{{cite journal |vauthors=Yamashita S, Masuda D, Matsuzawa Y |title=Did we abandon probucol too soon? |journal=Current Opinion in Lipidology |volume=26 |issue=4 |pages=304–16 |date=August 2015 |pmid=26125504 |doi=10.1097/MOL.0000000000000199 |quote=Probucol has been used as a lipid-lowering drug for a long time especially in Japan, although Western countries quitted its use because of the reduction in serum HDL-cholesterol (HDL-C).}} It predated the statins by about a decade.{{cite journal |vauthors=Yamashita S, Masuda D, Matsuzawa Y |title=New Horizons for Probucol, an Old, Mysterious Drug |journal=Journal of Atherosclerosis and Thrombosis |volume=28 |issue=2 |pages=100–102 |date=February 2021 |pmid=32507832 |pmc=7957029 |doi=10.5551/jat.ED132}}

• Phytosterols may be found naturally in plants. Similar to ezetimibe, phytosterols reduce the absorption of cholesterol in the gut, so they are most effective when consumed with meals. However, their precise mechanism of action differs from ezetimibe.
• Omega-3 supplements taken at high doses can reduce levels of triglycerides.{{Cite web|url=https://www.nccih.nih.gov/health/omega3-supplements-in-depth|title=Omega-3 Supplements: In Depth|date=2018-05-01|website=NCCIH|language=en|access-date=2021-02-02}} They are associated with a very modest increase in LDL (~5%).
