Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood. It belongs to a class of drugs called statins [1]. According to the first source, there is no known interaction between Lipitor and muscle relaxants. However, it is always important to consult with a healthcare provider before taking any new medications, including muscle relaxants, while on Lipitor.

The second source is a research article that discusses the potential side effects of statins, including muscle pain and weakness. The article notes that while these side effects are relatively rare, they can be severe and may require discontinuation of the medication. The article also suggests that some patients may be more susceptible to these side effects than others, and that additional research is needed to better understand the mechanisms behind statin-related muscle problems [2].

The third source is a clinical trial that is currently recruiting participants to investigate the effects of atorvastatin on muscle function in patients with spinal cord injury. The trial aims to determine whether atorvastatin can improve muscle strength and reduce muscle wasting in this population. The trial is expected to be completed in 2022 [3].

In summary, while there is no known interaction between Lipitor and muscle relaxants, patients taking Lipitor should be aware of the potential for muscle pain and weakness as a side effect of the medication. It is important to discuss any concerns or questions about medication interactions or side effects with a healthcare provider.
