Description

Armodafinil is the enantiopure of the wakefulness-promoting agent modafinil (Provigil), and is indicated to improve wakefulness in adult patients with excessive sleepiness associated with obstructive sleep apnea (OSA), narcolepsy, or shift work disorder (SWD). Research has shown that armodafinil significantly improves driving simulator performance in patients with SWD. Armodafinil consists of the (−)-R-enantiomer of the racemic modafinil. Armodafinil is produced by the pharmaceutical company Cephalon Inc. (a wholly owned subsidiary of Teva Pharmaceutical Industries Ltd.) and was approved by the U.S. Food and Drug Administration (FDA) in June 2007.

Pharmacology

Indication

Investigated for use/treatment in sleep disorders, obstructive sleep apnea, schizophrenia and schizoaffective disorders, depression, and bipolar disorders.

Structured Indications
Pharmacodynamics
Not Available
Mechanism of action

Nuvigil (armodafinil) is a single-isomer of modafini. The exact mechanism of action is unknown. Armodafinil 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. Armodafinil 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]

TargetActionsOrganism
ASodium-dependent dopamine transporter
antagonist
inhibitor
Human
Absorption

Peak plasma concentrations are attained at approximately 2 hours when fasted, and can be delayed approximately 2-4 hours in a fed state. Since the delay in tmax is also associated with elevated plasma concentrations later in time, food can potentially affect the onset and time course of pharmacologic action for armodafinil.

Volume of distribution

Apparent volume of distribution: 42L.

Protein binding

Specific data unavailable. Similar to modafinil: approximately 60%, primarily to albumin.

Metabolism

In vitro and in vivo data show that armodafinil undergoes hydrolytic deamidation, S-oxidation, and aromatic ring hydroxylation, with subsequent glucuronide conjugation of the hydroxylated products. Amide hydrolysis is the single most prominent metabolic pathway, with sulfone formation by cytochrome P450 (CYP) 3A4/5 being next in importance. The other oxidative products are formed too slowly in vitro to enable identification of the enzyme(s) responsible. Only two metabolites reach appreciable concentrations in plasma (i.e., R-modafinil acid and modafinil sulfone). Data specific to armodafinil disposition are not available.

Route of elimination
Not Available
Half life

Terminal half-life is approximately 15 hours.

Clearance

The oral clearance of armodafinil is approximately 33 mL/min.
