Investigations on Differences in Atorvastatin Metabolite Ratios as a Diagnostic Tool in Detecting Atorvastatin Induced Myotoxicity

The primary objective of the study is to investigate whether differences in atorvastatin metabolite ratios might have a positive or negative predictive value in diagnosing atorvastatin muscle toxicity. A muscle biopsy is also collected and investigated.
