Statin-associated autoimmune myopathy (SAAM), also known as anti-HMGCR myopathy, is a very rare form of muscle damage caused by the immune system in people who take statin medications. [1] However, there are cases of SAAM in patients who have not taken statin medication, and this can be explained by the exposure to natural sources of statin ...
As with all statins, there is a concern of rhabdomyolysis, a severe undesired side effect. The U.S. Food and Drug Administration (FDA) has indicated that "it does not appear that the risk [of rhabdomyolysis] is greater with Crestor than with other marketed statins", but has mandated that a warning about this side-effect, as well as a kidney ...
Rhabdomyolysis may cause kidney failure by several mechanisms. The most important is the accumulation of myoglobin in the kidney tubules . [ 10 ] [ 11 ] [ 13 ] Normally, the blood protein haptoglobin binds circulating myoglobin and other heme-containing substances, but in rhabdomyolysis the quantity of myoglobin exceeds the binding capacity of ...
[64] [65] [66] Statin induced rhabdomyolysis, as with other statin associated muscle symptoms, occurs most commonly in the first year of treatment but can occur at any time during treatment. [64] Risk factors for statin induced rhabdomyolysis include older age, renal impairment, high dose statins and use of medications that reduce the breakdown ...
The incidence of rhabdomyolysis was 0.44 per 10,000 patients treated with statins other than cerivastatin. However, the risk was over 10-fold greater if cerivastatin was used, or if the standard statins (atorvastatin, fluvastatin, lovastatin, pravastatin, or simvastatin) were combined with a fibrate ( fenofibrate or gemfibrozil ) treatment.
Cerivastatin (INN, [1] brand names: Baycol, Lipobay) is a synthetic member of the class of statins used to lower cholesterol and prevent cardiovascular disease.It was marketed by the pharmaceutical company Bayer A.G. in the late 1990s, competing with Pfizer's highly successful atorvastatin (Lipitor).
After multiple hospitalizations for myoglobinuria and rhabdomyolysis, many misdiagnoses, and many different doctors and tests that were unable to give an explanation for her symptoms, through the assistance of the show genetic sequencing confirmed that she had CPT-II deficiency (a fatty-acid metabolism disorder).
Serious side effects may include rhabdomyolysis, liver problems, and diabetes. [5] Use during pregnancy may harm the fetus. [5] Like all statins, pravastatin works by inhibiting HMG-CoA reductase, an enzyme found in liver that plays a role in producing cholesterol. [5] Pravastatin was patented in 1980 and approved for medical use in 1989. [6]
