Modafinil is a medication renowned for its remarkable ability to enhance wakefulness and cognitive function. It is predominantly prescribed to address excessive daytime sleepiness associated with conditions such as narcolepsy, obstructive sleep apnea, and shift work sleep disorder. Distinguishing itself from traditional stimulants like amphetamines, Modafinil operates by selectively targeting neurotransmitters in the brain, such as dopamine and norepinephrine. This targeted approach enhances alertness without inducing the jittery sensations often linked with stimulant use.
