Modalert 100 mg

Modalert 100 mg is a popular brand of modafinil, a wakefulness promoting drug originally intended to treat excessive sleep disorders associated with Narcolepsy, Sleep Apnea and Shift Worker Sleep Disorder. Each tablet contains 100 mg of modafinil, an eugeroic that functions by changing some neurotransmitters in the brain. 

MECHANISM OF ACTION 

The mechanism of action of modafinil is not completely understood, but it functions by modulating several neurotransmitters in the brain: 

• Dopamine

Modafinil weakly binds and inhibits the dopamine transporter (DAT), increasing the extracellular dopamine levels without the intense rush of euphoria like the classic stimulants. 

• Norepinephrine

Modafinil increases norepinephrine levels in the hypothalamus and other sleep-regulating regions, boosting alertness. 

• Orexin 

Activates orexin-producing neurons in the hypothalamus which help stabilize wakefulness. 

• GABA 

Lowers the levels of GABA (gamma aminobutyric acid) that also lowers the brain’s primary inhibiting signals to facilitate wakefulness.
