Eugeroic related to Adrafinil. Weak Dopamine Reuptake Inhibitor (DRI). Psychotonic.

CRL-40,941 (Fladrafinil) is a psychotonic and eurgeroic (wakefulness-promoting substance) that is related to Adrafinil and CRL-40,940, with similar but more potent effects demonstrated in animal models. Fladrafinil is the bis(p-fluoro) derivative of Adrafinil, and is, therefore, often referred to as “Fladrafinil”.
