Modalert 200mg (Modafinil) is frequently called a "smart Pills" or nootropic because of its capacity to improve cognitive function, attention, and alertness.  It improves cognitive performance and alertness by activating the brain and raising dopamine and other neurotransmitter levels.  Although it is often prescribed to treat problems including shift work sleep disorder, narcolepsy, and sleep apnea, some healthy people take it off-label to improve their cognitive function, such as their ability to focus better for extended periods of work or study.
