Myoadenylate deaminase deficiency. Adenosine monophosphate. Adenosine monophosphate deaminase deficiency type 1 or AMPD1, is a human metabolic disorder in which the body consistently lacks the enzyme AMP deaminase, [ 1] in sufficient quantities. This may result in exercise intolerance, muscle pain and muscle cramping.
Rare. 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 ...
Lovastatin, a compound isolated from Aspergillus terreus, was the first statin to be marketed. Statins (or HMG-CoA reductase inhibitors) are a class of medications that reduce illness and mortality in people who are at high risk of cardiovascular disease. They are the most commonly prescribed cholesterol-lowering drugs.
Acquired non-inflammatory myopathy (ANIM) is a neuromuscular disorder primarily affecting skeletal muscle, most commonly in the limbs of humans, resulting in a weakness or dysfunction in the muscle. [1] A myopathy refers to a problem or abnormality with the myofibrils, which compose muscle tissue. In general, non-inflammatory myopathies are a ...
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 ...
Statin-induced rhabdomyolysis is rare; occurring in less than 0.1% of people who take statins. [63] [64] [65] Statin induced rhabdomyolysis, as with other statin associated muscle symptoms, occurs most commonly in the first year of treatment however can occur at any time during treatment. [63]
HMG-CoA reductase ( 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase, official symbol HMGCR) is the rate-controlling enzyme (NADH-dependent, EC 1.1.1.88; NADPH-dependent, EC 1.1.1.34) of the mevalonate pathway, the metabolic pathway that produces cholesterol and other isoprenoids. HMGCR catalyzes the conversion of HMG-CoA to mevalonic acid, a ...
Simvastatin. Simvastatin, sold under the brand name Zocor among others, is a statin, a type of lipid-lowering medication. [ 4] It is used along with exercise, diet, and weight loss to decrease elevated lipid levels. [ 4] It is also used to decrease the risk of heart problems in those at high risk. [ 4] It is taken by mouth.
