How does statin cause myopathy?
Any factor that increases the serum concentration of a statin has the potential to increase the risk of myopathy. Therefore, factors that affect the pharma- cokinetics of statins, leading to increased concentra- tions of the drugs in blood or tissue, may predispose to myopathy.
Why does statin cause myalgia?
According to the study, statins don’t just prevent the production of cholesterol in the cell, but also inhibit the production of energy in the mitochondria. This lower energy causes myalgia in muscle cells, the study authors noted.
Why does statin cause rhabdomyolysis?
Rhabdomyolysis is a well-documented side effect of statin therapy. This risk is increased with concurrent use of medications that inhibit cytochrome p450-3A4 (CYP3A4), such as macrolide antibiotics.
How do statins cause muscle weakness?
New research suggests that muscle weakness and related side effects that can arise from statin use is likely due to the drug’s effect on the energy production centers, or mitochondria, of muscle cells.
Which statin causes the most myopathy?
Certain statins are associated with a higher incidence of myopathy. Bruckert et al used pravastatin as a reference and demonstrated that atorvastatin and simvastatin were associated with higher incidences of myopathy, whereas fluvastatin XL was associated with a lower incidence.
How is statin induced myopathy diagnosed?
If you begin to show symptoms of muscle myopathy after starting statin therapy, talk to your doctor or physician as soon as possible. A blood test is usually ordered to measure creatine kinase levels and rule out rhabdomyolysis. If rhabdomyolysis is the culprit, statin treatment will be stopped immediately.
How is statin induced myopathy treated?
Currently, the only effective treatment of statin-induced myopathy is the discontinuation of statin use in patients affected by muscle aches, pains and elevated CK levels.
How is statin-induced myopathy treated?
How do you manage statin myopathy?
Coenzyme Q10 and vitamin D have been used to prevent and treat statin myopathy; however, clinical trial evidence demonstrating their efficacy is limited. Statin-intolerant patients may be successfully treated with either low-dose statins, alternate-day dosing, or using twice-weekly dosing with longer half-life statins.
Which statin has the lowest risk of myopathy?
These can be especially useful in patients with symptoms or risk of myopathy. Pravastatin has been considered by many as the only safe statin with regard to myopathy. Evidence in the scientific literature, however, is actually stronger for fluvastatin as having the lowest myopathy risk.
How is statin myopathy treated?
What does statin myopathy feel like?
SAMS can vary in frequency and severity. The following are the three most common forms of statin-related muscle pain: Myalgia: This type of muscle pain usually feels like mild soreness in the shoulders, arms, hips or thighs. Myalgia also often comes with mild feelings of weakness.
