Modafinil is a unique medication used to treat sleep disorders and improve alertness. It works differently from other stimulants and has specific brand and generic versions available.

Mechanism of Action

Modafinil affects cognitive processes by interacting with brain chemicals. It boosts dopamine levels by blocking dopamine transporters. This increases alertness and wakefulness.

Modafinil also impacts other neurotransmitters like norepinephrine and serotonin. It may enhance glutamate and decrease GABA activity in the brain.

Unlike amphetamines, modafinil doesn’t cause a large dopamine surge. This leads to lower abuse potential and fewer side effects.

Drug Classification and Pharmacology

Modafinil is classified as a central nervous system stimulant. It’s a Schedule IV controlled substance in the United States. This means it has accepted medical uses but some potential for abuse.

The drug has a complex pharmacological profile. It’s absorbed quickly when taken orally. Peak blood levels occur 2-4 hours after ingestion.

Modafinil is broken down in the liver. Its main metabolites are modafinil acid and modafinil sulfone. These can be detected in plasma.

The half-life of modafinil is about 15 hours. This allows for once-daily dosing in most cases.

Brand and Generic Names

Modafinil is sold under several brand names. The most common is Provigil. Other brands include Alertec, Modavigil, and Modalert.

Generic modafinil became available in 2012 after Provigil’s patent expired. Generic versions are typically cheaper than brand-name Provigil.

Some countries have approved armodafinil. This is the R-enantiomer of modafinil. It’s sold under brand names like Nuvigil and Waklert.

Both brand and generic forms contain the same active ingredient. They should have similar effects when taken as prescribed.

Indications and Uses
