Lyrica, also known as pregabalin, is a medication primarily used to treat epilepsy, neuropathic pain, and anxiety disorders. According to Drug Patent Watch [1], Lyrica was approved by the FDA in 2004, and its patent expired in 2018. However, the use of Lyrica for long-term endurance training is not supported by scientific evidence.

A study published in the Journal of Clinical Psychopharmacology [2] examined the effects of pregabalin on cognitive and psychomotor performance in healthy volunteers. The study found that pregabalin had no significant effect on cognitive or psychomotor performance, suggesting that it may not enhance endurance training.

Furthermore, the NHS [3] recommends physical therapy and occupational therapy as treatment options for ataxia, a condition that affects coordination and balance. While Lyrica may be used to treat ataxia, it is not recommended for long-term use as it can cause side effects such as dizziness, drowsiness, and blurred vision.

In conclusion, while Lyrica may be used to treat certain medical conditions, there is no scientific evidence to support its use for long-term endurance training. It is important to consult with a healthcare professional before using Lyrica or any other medication for off-label purposes.
