<!-- Definition and medical uses -->
'''Statins''' (or '''HMG-CoA reductase inhibitors''') are a [[Drug class|class]] of medications that lower [[cholesterol]]. They are prescribed typically to people who are at high risk of [[cardiovascular disease]].<ref name="Cardiovascular Media">{{cite web |title=Cholesterol Drugs |url=https://watchlearnlive.heart.org/?moduleSelect=chldrg |access-date=24 December 2019 |website=[[American Heart Association]] |archive-date=12 August 2020 |archive-url=https://web.archive.org/web/20200812143713/https://watchlearnlive.heart.org/?moduleSelect=chldrg |url-status=live }}</ref>

[[Low-density lipoprotein]] (LDL) carriers of [[cholesterol]] play a key role in the development of [[atherosclerosis]] and [[coronary heart disease]] via the mechanisms described by the [[lipid hypothesis]].

In this latter group, statin assignment was not automatic, but was recommended to occur only after a clinician-patient risk discussion with shared decision making where other risk factors and lifestyle are addressed, the potential for benefit from a statin is weighed against the potential for adverse effects or drug interactions and informed patient preference is elicited. Moreover, if a risk decision was uncertain, factors such as family history, coronary calcium score, [[Ankle-brachial pressure index|ankle-brachial index]], and an inflammation test ([[C-reactive protein|hs-CRP]] ≥ 2.0&nbsp;mg/L) were suggested to inform the risk decision.

[[File:HMG-CoA reductase pathway.svg|thumb|546x546px|class=skin-invert-image|The HMG-CoA reductase pathway, which is blocked by statins via inhibiting the rate limiting enzyme [[HMG-CoA reductase]].]]

Statins act by [[competitive inhibitor|competitively inhibiting]] [[HMG-CoA reductase]], the rate-limiting [[enzyme]] of the [[mevalonate pathway]]. Because statins are similar in structure to [[HMG-CoA]] on a molecular level, they will fit into the enzyme's active site and compete with the native substrate (HMG-CoA). This competition reduces the rate by which [[HMG-CoA reductase]] is able to produce [[mevalonate]], the next molecule in the [[mevalonate pathway|cascade that eventually produces cholesterol]]. A variety of natural statins are produced by ''[[Penicillium]]'' and ''[[Aspergillus]]'' fungi as [[secondary metabolites]]. These natural statins probably function to inhibit HMG-CoA reductase enzymes in bacteria and fungi that compete with the producer.<ref name="Endo1992">{{cite journal | vauthors = Endo A | title = The discovery and development of HMG-CoA reductase inhibitors | journal = Journal of Lipid Research | volume = 33 | issue = 11 | pages = 1569–1582 | date = November 1992 | pmid = 1464741 | doi = 10.1016/S0022-2275(20)41379-3 | doi-access = free | title-link = doi }}</ref>

===Inhibiting cholesterol synthesis===
By inhibiting HMG-CoA reductase, statins block the pathway for synthesizing cholesterol in the liver. This is significant because most circulating cholesterol comes from internal manufacture rather than the diet. When the liver can no longer produce cholesterol, levels of cholesterol in the blood will fall. Cholesterol synthesis appears to occur mostly at night,<ref>{{cite journal | vauthors = Miettinen TA | title = Diurnal variation of cholesterol precursors squalene and methyl sterols in human plasma lipoproteins | journal = Journal of Lipid Research | volume = 23 | issue = 3 | pages = 466–473 | date = March 1982 | pmid = 7200504 | doi = 10.1016/S0022-2275(20)38144-X | doi-access = free | title-link = doi }}</ref> so statins with short [[half-life|half-lives]] are usually taken at night to maximize their effect.

In rabbits, [[hepatocyte|liver cells]] sense the reduced levels of liver cholesterol and seek to compensate by synthesizing [[LDL receptor]]s to draw cholesterol out of the circulation.<ref name="Ma1986">{{cite journal | vauthors = Ma PT, Gil G, Südhof TC, Bilheimer DW, Goldstein JL, Brown MS | title = Mevinolin, an inhibitor of cholesterol synthesis, induces mRNA for low density lipoprotein receptor in livers of hamsters and rabbits | journal = Proceedings of the National Academy of Sciences of the United States of America | volume = 83 | issue = 21 | pages = 8370–8374 | date = November 1986 | pmid = 3464957 | pmc = 386930 | doi = 10.1073/pnas.83.21.8370 | doi-access = free | title-link = doi | bibcode = 1986PNAS...83.8370M }}</ref> This is accomplished via [[protease]]s that cleave membrane-bound [[sterol regulatory element binding protein]]s, which then migrate to the [[cell nucleus|nucleus]] and bind to the sterol response elements. The sterol response elements then facilitate increased transcription of various other proteins, most notably, [[LDL receptor]]. The LDL receptor is transported to the liver [[cell membrane]] and binds to passing [[low density lipoprotein|LDL]] and [[very low density lipoprotein|VLDL]] particles, mediating their uptake into the liver, where the cholesterol is reprocessed into bile salts and other byproducts. This results in a net effect of less LDL circulating in blood.{{cn|date=May 2024}}

===Decreasing of specific protein prenylation===
Statins, by inhibiting the HMG CoA reductase pathway, inhibit downstream synthesis of isoprenoids, such as [[farnesyl pyrophosphate]] and [[geranylgeranyl pyrophosphate]]. Inhibition of protein [[prenylation]] for proteins such as [[Transforming protein RhoA|RhoA]] (and subsequent inhibition of [[Rho-associated protein kinase]]) may be involved, at least partially, in the improvement of endothelial function, modulation of immune function, and other [[Pleiotropy|pleiotropic]] cardiovascular benefits of statins,<ref>{{cite journal | vauthors = Laufs U, Custodis F, Böhm M | title = HMG-CoA reductase inhibitors in chronic heart failure: potential mechanisms of benefit and risk | journal = Drugs | volume = 66 | issue = 2 | pages = 145–154 | year = 2006 | pmid = 16451090 | doi = 10.2165/00003495-200666020-00002 | s2cid = 46985044 }}</ref><ref>{{cite journal | vauthors = Greenwood J, Steinman L, Zamvil SS | title = Statin therapy and autoimmune disease: from protein prenylation to immunomodulation | journal = Nature Reviews.

As the target of statins, the HMG-CoA reductase, is highly similar between [[eukaryota]] and [[archaea]], statins also act as antibiotics against archaea by inhibiting archaeal mevalonate biosynthesis.

The longer the half-life of the statin, the longer the inhibition of reductase and thus a greater reduction in LDL cholesterol. However, the impact of inhibiting cholesterol synthesis persists even with statins that have a relatively short half-life. This is due to their ability to reduce blood levels of lipoproteins, which have a half-life of approximately 2 to 3 days. Because of this, all statins may be dosed once daily. The preferable time of administration is in the evening just before the peak in cholesterol synthesis. }}</ref>

{{Main|Statin development}}

The role of cholesterol in the development of cardiovascular disease was elucidated in the second half of the 20th century.<ref>{{cite journal | vauthors = Goldstein JL, Brown MS | title = A century of cholesterol and coronaries: from plaques to genes to statins | journal = Cell | volume = 161 | issue = 1 | pages = 161–172 | date = March 2015 | pmid = 25815993 | pmc = 4525717 | doi = 10.1016/j.cell.2015.01.036 }}</ref> This [[lipid hypothesis]] prompted attempts to reduce cardiovascular disease burden by lowering cholesterol. Treatment consisted mainly of [[Diet (nutrition)|dietary measures]], such as a [[low-fat diet]], and poorly tolerated medicines, such as [[clofibrate]], [[cholestyramine]], and [[nicotinic acid]]. Cholesterol researcher Daniel Steinberg writes that while the Coronary Primary Prevention Trial of 1984 demonstrated cholesterol lowering could significantly reduce the risk of heart attacks and angina, physicians, including cardiologists, remained largely unconvinced.<ref>{{cite book | vauthors = Steinberg D | title=The cholesterol wars: the skeptics vs. the preponderance of evidence | publisher=Academic Press | year=2007 | isbn=978-0-12-373979-7 | pages=6–9}}</ref> Scientists in academic settings and the pharmaceutical industry began trying to develop a drug to reduce cholesterol more effectively.

In 1971, [[Akira Endo (biochemist)|Akira Endo]], a Japanese biochemist working for the pharmaceutical company [[Daiichi Sankyo|Sankyo]], began to investigate this problem. Research had already shown cholesterol is mostly manufactured by the body in the liver with the enzyme HMG-CoA reductase.<ref name=Simons/> Endo and his team reasoned that certain microorganisms may produce inhibitors of the enzyme to defend themselves against other organisms, as [[mevalonate]] is a precursor of many substances required by organisms for the maintenance of their cell walls or [[cytoskeleton]] ([[isoprenoid]]s).<ref name="Endo1992"/> The first agent they identified was [[mevastatin]] (ML-236B), a molecule produced by the fungus ''[[Penicillium citrinum]]''.{{cn|date=May 2024}}

A British group isolated the same compound from ''Penicillium brevicompactum'', named it [[compactin]], and published their report in 1976.<ref>{{cite journal | vauthors = Brown AG, Smale TC, King TJ, Hasenkamp R, Thompson RH | title = Crystal and molecular structure of compactin, a new antifungal metabolite from Penicillium brevicompactum | journal = Journal of the Chemical Society, Perkin Transactions 1 | issue = 11 | pages = 1165–1170 | year = 1976 | pmid = 945291 | doi = 10.1039/P19760001165 }}</ref> The British group mentions antifungal properties, with no mention of HMG-CoA reductase inhibition.<ref>{{Cite journal |last1=Ko |first1=Humphrey H.T. |last2=Lareu |first2=Ricky R. |last3=Dix |first3=Brett R. |last4=Hughes |first4=Jeffery D. |date=24 October 2017 |title=Statins: antimicrobial resistance breakers or makers? |journal=PeerJ  |volume=5 |pages=e3952 |doi=10.7717/peerj.3952 | doi-access = free | title-link = doi |issn=2167-8359 |pmc=5659212 |pmid=29085751}}</ref><ref>{{Cite journal |last1=Gesto |first1=Diana S. |last2=Pereira |first2=Carlos M.

By 1978, Merck had isolated [[lovastatin]] (mevinolin, MK803) from the fungus ''[[Aspergillus terreus]]'', first marketed in 1987 as Mevacor.<ref name="Simons">{{cite journal |vauthors=Simons J |date=January 2003 |title=The $10 billion pill |url=https://money.cnn.com/magazines/fortune/fortune_archive/2003/01/20/335643/index.htm |journal=[[Fortune (magazine)|Fortune]] |volume=147 |issue=1 |pages=58–62, 66, 68 |pmid=12602122}}</ref>

In the 1990s, as a result of public campaigns, people in the United States became familiar with their cholesterol numbers and the difference between HDL and LDL cholesterol, and various pharmaceutical companies began producing their own statins, such as pravastatin (Pravachol), manufactured by Sankyo and [[Bristol-Myers Squibb]]. In April 1994, the results of a Merck-sponsored study, the [[Scandinavian Simvastatin Survival Study]], were announced. Researchers tested [[simvastatin]], later sold by Merck as Zocor, on 4,444 patients with high cholesterol and heart disease. After five years, the study concluded the patients saw a 35% reduction in their cholesterol, and their chances of dying of a heart attack were reduced by 42%.<ref name=Simons/><ref name="4S">{{cite journal | title = Randomised trial of cholesterol lowering in 4444 patients with coronary heart disease: the Scandinavian Simvastatin Survival Study (4S) | journal = Lancet | volume = 344 | issue = 8934 | pages = 1383–1389 | date = November 1994 | pmid = 7968073 | doi = 10.1016/S0140-6736(94)90566-5 | s2cid = 5965882 | last1 = Scandinaviansimvastatinsurvival }}</ref> In 1995, Zocor and Mevacor both made Merck over {{US$|1 billion}}.<ref name=Simons/>

They estimated that there could be up to 2,000 extra heart attacks or strokes over the following 10 years as a consequence.<ref>{{cite news | vauthors=Boseley S | title=Statins prevent 80,000 heart attacks and strokes a year in UK, study finds | work=[[The Guardian]] | date=8 September 2016 | url=https://www.theguardian.com/society/2016/sep/08/statins-prevent-80000-heart-attacks-and-strokes-a-year-in-uk-study-finds | access-date=29 December 2017 | archive-date=8 August 2017 | archive-url=https://web.archive.org/web/20170808234418/https://www.theguardian.com/society/2016/sep/08/statins-prevent-80000-heart-attacks-and-strokes-a-year-in-uk-study-finds | url-status=live }}</ref> An unintended effect of the academic statin controversy has been the spread of scientifically questionable [[Alternative medicine|alternative therapies]].
