Statins (prescription drugs to lower cholesterol) are considered a small risk. [9] Some people have inherited muscle conditions that increase the risk of rhabdomyolysis. [3] The diagnosis is supported by a urine test strip which is positive for "blood" but the urine contains no red blood cells when examined with a microscope. [3]
Common types of myopathy due to statins include myalgia, myositis, and rhabdomyolysis. Statins induce myopathy by inhibiting protein synthesis within the muscle. [6] Statin therapy tends to not show any histopathological differences, and thus a biopsy does not reveal too much about the damage. Often, the damage is found within the mitochondria.
Clinical presentations of rhabdomyolysis. While statins are generally well-tolerated, severe adverse effects such as hepatotoxicity and myotoxicity may occur in rarity. Statin-induced hepatotoxicity can cause autoimmune hepatitis and an elevation in serum levels of hepatic enzymes such as alanine aminotransferase, impairing liver function. [20]
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 ...
Combining any statin with a fibrate or niacin (other categories of lipid-lowering drugs) increases the risks for rhabdomyolysis to almost 6.0 per 10,000 person-years. [99] Monitoring liver enzymes and creatine kinase is especially prudent in those on high-dose statins or in those on statin/fibrate combinations, and mandatory in the case of ...
Statin-induced rhabdomyolysis is rare, occurring in less than 0.1% of people who take statins. [ 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 ]
There is an increased risk that statin (cholesterol-reducing drugs) will cause myopathy (muscle weakness) in individuals with MADD. [10] Anesthesia has the potential to cause malignant hyperthermia, an uncontrolled increase in body temperature, and permanent muscle damage in patients with MADD. Individuals with MADD are advised to notify their ...
In studies using standard doses, statins have been found to lower LDL-C by 18% to 55%, depending on the specific statin being used. A risk exists of muscle damage (myopathy and rhabdomyolysis) with statins. Hypercholesterolemia is not a risk factor for mortality in persons older than 70 years and risks from statin drugs are more increased after ...
