This four year study quantified the risk of myositis (myositis cases were defined as creatine kinase levels more than 10x upper limit of normal and a myopathy (muscle disease) diagnosis) associated with statin and fibrate drug use within a managed care organization population.
The study found:
(a) Statin users had a 180% increased risk of myositis compared to non-users.
(b) Statin-fibrate combination users had a 810% increased risk of myositis compared to non-users.
The results from this study show that statins, with or without fibrates, were significantly associated with increased myositis risk.
