Modafinil affects brain chemicals including dopamine, norepinephrine, and histamine to enhance wakefulness. Increases these hormones, which control sleep-wake cycles, improving alertness and cognition. Modafinil increases wakefulness and attentiveness by inhibiting dopamine reuptake. Unlike typical stimulants, it has less adverse effects and dependency risk. It may cure sleep problems including narcolepsy and sleep apnea and boost daytime alertness without the jitteriness of other stimulants.
