How Modafinil by AA Pharma Inc. works

Nuvigil (armodafinil) is a single-isomer of modafini. The exact mechanism of action is unknown. Modafinil by AA Pharma Inc. belongs to a class of drugs known as eugeroics, which are stimulants that provide long-lasting mental arousal. Pharmacologically, armodafinil does not bind to or inhibit several receptors and enzymes potentially relevant for sleep/wake regulation. Modafinil by AA Pharma Inc. is not a direct- or indirect-acting dopamine receptor agonist. However, in vitro, both armodafinil and modafinil bind to the dopamine transporter and inhibit dopamine reuptake. [Medilexicon]
