PURPOSE OF REVIEW: Statins are commonly prescribed lipid-lowering medications that significantly reduce the risk of cardiovascular events. However, they can have myotoxic effects ranging in severity from myalgias to rhabdomyolysis. This review focuses on recent progress in defining the clinical features and mechanism(s) of statin-induced myopathy.

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. 21 The antibody associated with immune mediated necrotizing myopathy frequently associated with prior statin use was first described by That was when I wrote my second book, Statin Drugs Side Effects and the Misguided War on Cholesterol.

6 Although myopathy can refer to any muscular disease, the recent clinical advisory on the use and safety of statins differentiated myalgia as muscle 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. The precise mechanisms underlying statin-associated myopathy are not well understood; however, theories do exist.

Pathological investigation of toxic myopathy reveals necrosis and regenerating muscle fibers, with a negative response to anti–HMG-CoA reductase autoantibodies. 34 The precise mechanisms behind toxic myopathy are unknown but have been suggested to be aggravated by conditions that increase statin levels in the blood, such as concomitant medications that interfere with statin metabolism via the CYPP450 enzymes, glucuronidation, or other processes. 19 This is particularly relevant as skeletal The mechanism for these adverse muscle reactions is unknown. That some patients receiving statins who experience muscle pain have normal creatine kinase levels suggests that muscle toxicity may Statins trigger overexpression of HMGCR in genetically susceptible patients, which propagates a positive bio feedback loop of autoimmune myopathy.

The mechanism for these adverse muscle reactions is unknown. Muscle biopsies showed myopathy during statin treatment with resolution five and one half months after treatment was halted.

Posted 21st October 2015 by Cyprotex. A recent paper by Schirris et al., 2015 has finally uncovered a mechanistic understanding of statin-induced myopathy. This type of toxicity is the most common side effect of the statins and severity ranges from muscle pain in up to 26% of patients to very In the sarcoplasma, statins activate MAPK and diminish the RhoA/AKT/mTOR/PGC-1α pathway. All these effects contribute to activate apoptosis, proteolysis, and muscle remodeling. Moreover, in the sarcoplasma, statins can reduce the resting chloride channel conductance, as well as lactate efflux.

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) .

The broad spectrum of statin myopathy Mechanism of apoptosis in statin-induced myopathy. Despite ongoing research efforts, the underlying pathology of statin induced myopathy remains largely speculative. Although the primary clinical use of statins is to lower cholesterol levels by inhibiting de novo cholesterol synthesis, evidence supports that a decreased cholesterol level likely is not a significant factor contributing to myopathy.

Symptoms of statin induced myopathy include fatigue, muscle pain, muscle tenderness, muscle weakness, nocturnal cramping, and tendon pain.
