Artvigil 150 mg vs. Modafinil – Which Works Better? Artvigil 150 mg and Modafinil are both wakefulness-promoting agents prescribed to treat sleep disorders such as narcolepsy, obstructive sleep apnea, and shift work disorder. Artvigil has Armodafinil, the R-enantiomer of Modafinil, which has a longer effect and possibly smoother energy levels during the day. Modafinil, however, has a faster onset and is usually used for short-term focus enhancement. Both are effective, though Artvigil is usually stronger at smaller doses because of its advanced formula. The best option will be determined by individual response, tolerance level, and wakefulness required. visit : https://lifecarepills.com/artvigil-150-mg/
