Statins May Be Linked To Muscle Damage

http://www.medicalnewstoday.com/articles/156545.php

A recent study published in the Canadian Medical Association Journal (CMAJ)

reports that patients taking statins with associated muscle complaints may have

structural muscle damage.

Because of their important role in reducing the risk of cardiovascular disease,

statins are one of the most widely prescribed medications worldwide. However,

many patients on statins develop muscle weakness and pain. In a number of cases,

muscle biopsies confirm underlying structural injury, even in patients who do

not show elevated levels of circulating creatine phosphokinase.

The study was the work of researchers from the University of Bern, Switzerland

and the Tufts-New England Medical Center in Boston, Massachusetts. They

evaluated muscle biopsies from eighty three patients. Twenty of them had never

taken statins. Results showed significant muscle injury in patients who had

taken statins, including several who had discontinued medication before the

biopsy.

Dr. Annette Draeger from the University of Bern and coauthors explain: " Although

in clinical practice, the majority of patients with muscle symptoms improve

rapidly after cessation of therapy, our findings support that a subgroup of

patients appears to be more susceptible to statin-associated myotoxicity,

suffering persistent structural injury. "

The researchers call for further evaluation of alternative treatment strategies

for patients with significant muscle symptoms.
