Provigil 200 mg

Modafinil is very much similar to armodafinil drug (Nuvigil). Apart from this, it is also supplied as Provigil 100 mg pills.

Like other amphetamines, Modafinil promotes wakefulness by stimulating the brain. It tends to work by increasing the amount of dopamine, a chemical neurotransmitter present in the brain by reducing the reuptake of dopamine into nerves. Modafinil drug was approved by the FDA for public after much analysis.
