Interaction Details
There were no interactions found between Armodafinil and Arsenic. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Arsenic Overview
Arsenic is a trace element naturally present in the diet, with organic forms being generally non-toxic in low amounts, while inorganic forms can be harmful. It is found in foods such as seafood, poultry, grains (especially rice), bread, cereal products, mushrooms, and dairy. The estimated daily intake of organic arsenic is 12-50 mcg, with a suggested requirement of 12-25 mcg daily, while inorganic arsenic intake is estimated at 3.5-10 mcg daily. Arsenic plays a potential role in metabolism, the recycling of methionine, taurine function, and the regulation of gene expression in the body. In traditional Chinese medicine, arsenic has been used to treat various inflammatory disorders, but it is generally only found in homeopathic preparations.
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.
