The wakefulness-inducing drug Armodafinil is the active component in the medicine Waklert 150mg. Armodafinil is thought to exert its effects via increasing the brain's supply of neurotransmitters like dopamine.

Although the specific method by which Armodafinil improves cognitive performance is not known, it is thought to include stimulation of the central nervous system to increase alertness and vigilance.

Armodafinil has been proven to enhance cognitive performance in healthy adults, specifically resulting in greater wakefulness, focus, and working memory. It has also been proven to improve things like planning, decision-making, and goal-directed behavior (all parts of the "executive function").
