I'm sorry, but based on the sources provided, I cannot answer your question as there is no information regarding the impact of Lipitor on yoga practice. The sources you provided are about Lipitor's patent expiration, its effectiveness in reducing cholesterol levels, and its potential side effects. None of these sources mention any impact of Lipitor on yoga practice.

Lipitor is a medication that belongs to a class of drugs called statins, which are used to lower cholesterol levels in the blood. It works by inhibiting an enzyme in the liver that is responsible for producing cholesterol. According to a study published in the Journal of Clinical Lipidology [2], Lipitor was found to be effective in reducing LDL cholesterol levels by up to 60%. However, like any medication, Lipitor may cause side effects such as muscle pain, weakness, and liver damage [3].

In conclusion, based on the sources provided, there is no information about how Lipitor impacts yoga practice. It is always recommended to consult with a healthcare professional before starting or stopping any medication.
