Vilafinil 400 mg

Vilafinil 400 mg is a wakefulness medication that is used to treat excessive sleepiness associated with certain sleep disorders. The medication consists of 400 mg of Modafinil, a Central Nervous System Stimulant. The medication can be taken with or without food. 

MECHANISM OF ACTION

Modafinil works by inhibiting the dopamine transporter, thereby increasing extracellular dopamine levels and indirectly activating noradrenaline pathways and other neurotransmitters in the brain. It also enhances brain signaling in the orexin, histamine, and glutamate pathways and decreases GABA activity, leading to improved alertness and cognitive performance without the significant euphoric effects typically associated with other stimulants.
