Researchers Uncover Cause of Muscle Pain from Statins

A Discovery That Could Transform Statin Therapy

Researchers at Columbia University have found that certain cholesterol inhibitors, known as statins, can cause muscle pain through a leakage of calcium into muscle cells. This issue has been encountered by many patients, leading them to abandon treatments due to muscle discomfort.

The recent study suggests that statins may bind to a critical protein, the ryanodine receptor, causing a leakage of calcium ions that disrupts normal muscle function. "While this explanation may not apply to all patients experiencing muscular side effects, even for a small segment, it represents a considerable number of people we could potentially help," stated Andrew Marks, Chair of the Department of Physiology and Cellular Biophysics at the Vagelos College of Physicians and Surgeons.

The good news is that these findings could pave the way for a new type of statin that protects muscles while improving cholesterol control. Marks is working with chemists to develop statin models that avoid this undesirable interaction.

Additionally, research has shown that it may be possible to stop calcium leaks using experimental drugs that are already being tested on patients with rare muscle diseases. If these trials prove effective, they could also be applied to patients suffering from statin-induced myopathies.
