Johnston8 & Amirhossein Sahebkar9,10,11 # The Author(s) 2020 Statins reduce hepatic cholesterol synthesis, lower levels of intracel-lular cholesterol, stimulate upregulation of the low-density lipopro-tein (LDL) receptor, and increase uptake of non-high-density lipo-protein particles from the systemic circulation. Further knowledge of the in vivo biodistribution of [18F]atorvastatin may help to better understand the origin of off-target effects and potentially allow to distinguish between statin-resistant and non-resistant patients. Statins are effective drugs to reduce cardiovascular events secondary to dyslipidemia; however, they cause frequent undesirable side effects.

Statins are a guideline-directed, first line therapy for prevention of primary and secondary cardiovascular disease (CVD), which is the leading cause of mortality worldwide [1,2]. Their major site of action is the liver, where they inhibit HMG-CoA (hydroxyl-methyl-glutaryl-coenzyme A) reductase, the rate-limiting step in cholesterol biosynthesis. Their major site of action is the liver, where they inhibit HMG-CoA (hydroxyl-methyl-glutaryl-coenzyme A) reductase, the rate-limiting step in cholesterol biosynthesis. Hepatocytes take up from the circulation ~ 50% of LDL cholesterol. endobj - Statins increase the … xref For authors For reviewers For editors Table of Contents. Download Pdf. These bio-molecular effects of fibrates are entirely due to their capacity to activate PPAR alpha and to induce the over expression of genes containing a PPRE in their promoter.

Although all statins share a common mechanism of action, they differ in terms of their chemical structures, pharmacokinetic profiles, and lipid-modifying efficacy. Add to favorites. Statins, among the most commonly prescribed drugs worldwide, are cholesterol-lowering agents used to manage and prevent cardiovascular and coronary heart diseases. Mechanism of Action, Antiviral drug promises and rule out against its treatment 4/20/20, 1744. Mauro Cimino. All these effects contribute to activate apoptosis, proteolysis, and muscle remodeling. Mechanism of Action Statins work by competitively blocking the active site of the first and key rate-limiting enzyme in the mevalonate pathway, HMG-CoA reductase. Article Metrics. Statins are directly associated with reducing the risk of cardiovascular events such as a heart attack and stroke by helping to reduce any cholesterol plaque that has built up in your arterial walls . Because statins are similar in structure to HMG-CoA on a molecular level, they will fit into the enzyme's active site and compete 0000013208 00000 n Export Citation. mechanism to the decreased incidence of stroke observed in patients on statins. These drugs differ with respect to mechanism of action and to the degree and type of lipid lowering. and other tumor-suppressor genes methylated in CRC - Statins induce differentiation in CRC cells in vitro and in a xenograft model in vivo and reduce stemness. REVIEW: Efficacy and mechanisms of action of statins in the treatment of diabetic dyslipidemia. One of the proposed mechanisms that has received a lot of attention is a statin-induced reduction of ubiquinone (coenzyme Q10) in myocytes.3-6 Coenzyme Q10 (CoQ10) is known to decrease oxidative stress through its antioxidant effects and participation in mitochondrial respiration (electron transport chain that generates the majority of the cell's ATP during aerobic metabolism).7-10 Early case reports … Statins, among the most commonly prescribed drugs worldwide, are cholesterol-lowering agents used to manage and prevent cardiovascular and coronary heart diseases. startxref Statins are among the most prescribed drugs in Western countries. Lipid altering agents encompass several classes of drugs that include hydroxymethylglutaryl (HMG) CoA reductase inhibitors or statins, fibric acid derivatives, bile acid sequestrants, cholesterol absorption inhibitors, and nicotinic acid. endobj >> Conventional dosing regimens and common adverse reactions are described in a table ( table 1 ) and the range of expected changes in the lipid profile are listed in a separate table ( table 2 ). In the present study, the pharmacology, mechanism of action, and metabolism of statins are reviewed, as well as their effects on tissues and numerous biological pro-cesses, such as those involved in the immune system, endothelia, smooth muscle, platelet function, in the me-tabolism, in the bone, and in the nervous system. 3 Schematic representation of statin mechanism of action. Published: 15 December 2015; The diabetogenic action of statins — mechanisms and clinical implications. The legend asserts that isolated alanine aminotransferase (ALT) elevations associated with statin therapy are harmful and must be avoided. Within the liver, this reduces hepatic cholesterol /MediaBox[0 0 595 842] Recently, a multifaceted action in different physiological and pathological conditions has been also proposed for statins, beyond anti-inflammation and neuroprotection. HMG-CoA reductase catalyses the conversion of HMG-CoA to L-mevalonate and coenzyme A via a four-electron reductive deacetylation (Figure 1). endobj Share. 3. Moreover, in the sarcoplasma, statins can reduce the resting chloride channel conductance, as well as lactate efflux. ... Possible mechanisms of statin action against influenza A virus pathogenesis in cellular and molecular structures. Pro-IL-1 is a 31 kDa protein that is secreted as an active 17 kDa form by caspase-1 following inflammasome activation. This mechanism may result in complete paralysis after very high statin doses, as noted in the first trials in Japan with very large doses of monacolin K . /ID[<991F9533F8BEC2E42BBC0FDD5AD1D28D>] The chemical structures of statins govern their water solubility, which in turn influences their absorption, distribution, metabolism and excretion.
