The popular wakefulness-promoting medication Modalert 200, which contains the active component modafinil, is often used to treat shift work sleep disorder, narcolepsy, and sleep apnea. Modafinil, in contrast to conventional stimulants, increases attention and alertness without producing the jitteriness that is sometimes linked to amphetamines or caffeine. It promotes alertness and cognitive performance by acting on certain neurotransmitters in the brain.
