How does Modvigil 200 mg work?
Modvigil is an atypical dopamine reuptake inhibitor. It blocks the dopamine transporter and also prevents the reabsorption of dopamine into the neurons and thus it leads to increased focus, alertness. Modafinil also stimulates the orexin-hypocretin system in the hypothalamus which triggers the release of histamine, a neurotransmitter that dictates your sleep-wake cycle. The medication increases brain processing speed and fights fatigue by increasing the levels of excitatory glutamate and down-regulating inhibitory GABA. It also increases the levels of norepinephrine which contributes to overall arousal and vigilance.Â
