Do Statins Really Cause Muscle Aches?

Many individuals who take the cholesterol-lowering statin medicine report that they trigger muscle ache, however a randomized trial means that the ache is not any totally different once they take a placebo capsule.

In uncommon instances, statins are recognized to trigger a extreme muscle situation referred to as rhabdomyolysis, during which skeletal muscle tissue is destroyed, resulting in critical problems. But far more continuously, folks complain that the medicine merely trigger muscle ache.

Whether statins are answerable for the muscle ache, nonetheless, stays unsure. Muscle ache has many causes and is frequent within the older age group utilizing statins, so figuring out whether or not statins are inflicting the ache is just not simple. Results from observational research, together with many media studies, might have led some to unnecessarily discontinue a therapy that’s probably lifesaving.

This new study, published in BMJ, concerned a sequence of what’s often known as n-of-1 medical trials, a strategy that permits researchers to look at the outcomes of therapy and placebo in particular person sufferers, fairly than learning them as a gaggle. In impact, every affected person serves as his or her personal management.

Researchers assembled 200 folks in England and Wales who had both stopped or deliberate to cease taking statins due to insupportable muscle ache. For a year, every affected person randomly took both a statin or a placebo capsule over six two-month durations. Half the time they acquired 20 milligrams of Lipitor, and the opposite half they acquired a look-alike dummy capsule. Until the tip of the examine, neither the researchers nor the sufferers knew once they had been taking the statin and once they had been taking the placebo.

During the final seven days of every two-month part, the researchers measured every affected person’s ache day by day utilizing a validated 10-point visible ache scale, with 10 indicating the worst potential ache. They additionally tracked different features of day by day life, together with the affected person’s normal exercise stage, temper, consolation in strolling, capability to pursue regular work actions, social relationships, sleep and delight of life.

The examine discovered no variations between the statin and placebo durations in both muscle ache or studies on day by day life actions and moods. Nine p.c withdrew due to ache whereas they had been on statins, however so did 7 p.c who had been taking placebos, an insignificant distinction.

“These studies are difficult to do,” mentioned Dr. Henry N. Ginsberg, a professor of drugs at Columbia who was not concerned within the work. “This one is done as well as you can, and it’s a nice one to talk about with patients. You can tell your patients, ‘They’ve done studies in people like you, and these people couldn’t tell the difference between placebo and medicine.’”

Three months after the ultimate therapy, when the sufferers had been knowledgeable of their outcomes, the researchers requested them whether or not they had restarted statins, or supposed to, and whether or not they discovered their very own trial consequence useful in making their resolution. Most of the sufferers mentioned that the trial was useful, and greater than two-thirds reported that they deliberate to start out taking statins once more.

The lead creator, Dr. Liam Smeeth, a main care doctor and professor of medical epidemiology on the London School of Hygiene and Tropical Medicine, mentioned that when folks cease statins due to muscle ache “they’re missing out on the huge benefits — reducing the risk of heart attack or stroke by about a third. What we’ve shown is that among these people who gave up their medicine because of pain — and their pain was real — it wasn’t made worse by statins.”
