and is the primary mechanism of glucose uptake via the GLUT transporters. Statins (e.g., atorvastatin) competitively and reversibly inhibit HMG-CoA reductase. Hepatotoxicity (up LFTs), myopathy (esp. when used with fibrates or niacin).

https Risk Factors and Drug Interactions Predisposing to Statin-Induced Myopathy Implications for Risk Assessment, Prevention and Treatment Yiannis S. Chatzizisis,1,2 Konstantinos C. Koskinas,2 Gesthimani Misirli,1 Christos Vaklavas,3 We revealed a mechanism by which statin treatment can make skeletal muscles susceptible to myopathy—dissociation of the FK506 binding protein (FKBP12) from the sarcoplasmic reticulum (SR) Ca 2+ release channel, the ryanodine receptor 1 (RyR1), which is accompanied by numerous spontaneous Ca 2+ release events (i.e., Ca 2+ sparks) . RECENT FINDINGS: The fundamental mechanism of statin myopathy remains elusive but is believed to be a class effect. The most common explanation for the cause of toxic muscle injury invokes the deficiency of one of three main synthetic products in the 3-hydroxy-3-methylglutaryl-coenzyme A reductase pathway. Statin-associated myopathy (SAM) represents one of the most significant and frequent side effects of these drugs, and it is estimated that up to two thirds of all statin-related side effects involve muscle tissue (Raju et al. 2013). Observational studies suggest that 10-15 % of statin users develop some type of muscle problem The current proposed mechanism involves damage to muscle cells by autoantibodies directed against HMG-CoA reductase, an enzyme present in muscle cells to which statins are directed. 4 HMG-CoA reductase is increased in muscle cells exposed to statins.

Myopathy is a condition in which the muscles become inflamed or do not function normally, states WebMD. Se hela listan på hindawi.com thy observed with statins; however, most cases of myopathy can be avoided or minimized if the clinician has a good knowledge of the pharma-cokinetic and pharmacodynamic properties of statins, the mechanism of statin–drug inter-actions and is aware of the populations at risk for statin myopathy. In this article, we discuss The mechanism by which statins cause myopathy is not completely understood. However, the association appears to be dose dependent, and the risk is known to increase when statins are prescribed in combination with agents that are also myotoxic when used as monotherapy or increase the serum concentration of the statin. Drug-induced myopathy (DIM) is a rare side effect; however, the consequence could be fatal. There are few reports to systematically assess the underlying mechanism of DIM. In this study, we curated the comprehensive DIM drug list based on structured labeling products (SPLs) and carried out the analysis based on chemical structure space, drug protein interaction, side effect space, and Although the mechanism for ezetimibe myopathy is unclear, the similar muscle biopsy findings of these patients to statin myopathy, may also suggest an underlying mitochondrial dysfunction [34, 35]. Mitochondrial dysfunction with mitochondrial‐mediated apoptosis appears to be the common underlying pathophysiology of myopathy in patients treated with statins, fibrates, and ezetimibe.

The mechanisms causing statin-induced myopathy have not been elucidated; however, research efforts suggest that apoptosis of myofibers may contribute.

In this study, we curated the comprehensive DIM drug list based on structured labeling products (SPLs) and carried out the analysis based on chemical structure space, drug protein interaction, side effect space, and Immunologically induced inflammatory myopathy – The myopathy associated with D-penicillamine is an example of this mechanism. Statin-associated autoimmune myopathy demonstrates that a single agent may cause myopathy by more than one mechanism.

The most common explanation for the cause of toxic muscle injury invokes the deficiency of one of three main synthetic products in the 3-hydroxy-3-methylglutaryl-coenzyme A reductase pathway. 2020-06-06 The impact of statins on skeletal myocytes may occur via insertion of the statin molecule into the cell membrane, which in turn may potentiate membrane instability under exercise stress. Exposure of skeletal muscle to statins and their metabolites equally involves effects on muscle metabolism independently of exercise. Multiple pathophysiological mechanisms may contribute to statin myotoxicity. This review focuses on a number of them. The prevention of statin-related myopathy involves using the lowest statin dose required to achieve therapeutic goals and avoiding polytherapy with drugs known to increase systemic exposure and myopathy risk.

Coenzyme Q10 (ubiquinone) levels are decreased in statin use; CoQ10 supplements are sometimes used to treat statin-associated myopathy, though evidence of their efficacy is lacking as of 2017.

The underlying mechanism is still unknown. Mitochondrial dysfunction related to coenzyme Q10 decline is one of the proposed theories. The present study aimed to investigate the mechanism of atorvastatin-induced myopathy in rats. The precise mechanisms underlying statin-associated myopathy are not well understood; however, theories do exist. One proposed mechanism suggests that decreased cholesterol concentrations secondary The exact mechanism for statin-associated myopathy is not fully known and may be multifactorial. Historically myopathy is attributed to the statins' ability to decrease ubiquinone (coenzyme Q10; CoQ10) formation because of a secondary decrease in mevalonate formation at the level of HMG-CoA reductase.
