What is Adrafinil ?

Adrafinil , aka CRL-40028, is a mild stimulant affecting the central nervous system. It is commonly used without a prescription by people who need to stay awake and alert for long periods of time. This nootropic is the prodrug to Modafinil. Because of this, CRL-40028 and Modafinil have almost identical pharmacological effects.

CRL-40028 was discovered in the late 1970’s by scientists working for the pharmaceutical company, Lafon. Lafon is the same company that later developed Modafinil. One huge difference between these two nootropics is that Modafinil is classified as a controlled substance in the United States while CRL-40028 is not.

How Does Adrafinil Work?

Adrafinil(CRL-40028) is the prodrug to Modafinil. This means that CRL-40028 is administered in an inactive form. Once ingested, this inactive form is metabolized into an active metabolite. In this case, CRL-40028 is metabolized to Modafinil.

Once metabolized to Modafinil, it works in a similar fashion. Recent studies suggest that Modafinil affects dopamine transporters by inhibiting the breakdown of dopamine. This means that your body is not absorbing dopamine leading to much greater dopamine levels. Greatly elevated dopamine levels result in CRL-40028 having many nootropic properties.
