Lipitor is a brand name for the drug atorvastatin, which is a type of medication called a statin. Statins are commonly used to lower cholesterol levels in the blood and reduce the risk of heart disease and stroke. According to Drug Patent Watch [1], the patent for Lipitor expired in 2011, which means that generic versions of atorvastatin are now available.

Regarding the long-term use of atorvastatin, a review of the drug's safety and efficacy published in the National Library of Medicine [2] states that atorvastatin is generally well-tolerated and safe for long-term use. However, like all medications, it may cause side effects in some people. The most common side effects of atorvastatin include muscle pain, liver problems, and gastrointestinal issues.

When it comes to stroke treatment, the use of statins like atorvastatin is recommended in certain cases. According to UpToDate [3], statins are typically used to lower cholesterol levels and reduce the risk of recurrent stroke in people who have had an ischemic stroke (a type of stroke caused by a blood clot in the brain). However, the decision to use statins for stroke prevention should be made on a case-by-case basis, taking into account the individual's medical history and other factors.

In conclusion, atorvastatin (Lipitor) can be used long-term for recovery, as it is generally well-tolerated and safe for long-term use. However, like all medications, it may cause side effects in some people. The use of atorvastatin in stroke treatment is recommended in certain cases, but the decision to use it should be made on a case-by-case basis.
