Interaction Details

Armodafinil is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, tree turmeric might increase the levels and clinical effects of drugs that are substrates of CYP3A4.
In vitro research and preliminary clinical evidence suggest that berberine, a constituent of tree turmeric, moderately inhibits CYP3A4.

Armodafinil Overview

• Armodafinil is used to treat excessive sleepiness caused by narcolepsy (a condition that causes excessive daytime sleepiness) or shift work sleep disorder (sleepiness during scheduled waking hours and difficulty falling asleep or staying asleep during scheduled sleeping hours in people who work at night or on rotating shifts). Armodafinil is also used along with breathing devices or other treatments to prevent excessive sleepiness caused by obstructive sleep apnea/hypopnea syndrome (OSAHS; a sleep disorder in which the patient briefly stops breathing or breathes shallowly many times during sleep and therefore does not get enough restful sleep). Armodafinil is in a class of medications called wakefulness-promoting agents. It works by changing the amounts of certain natural substances in the area of the brain that controls sleep and wakefulness.
