Armodafinil is a prescription medication used to improve wakefulness in adults with narcolepsy, obstructive sleep apnea, and shift work sleep disorder [1]. It is a central nervous system stimulant that works by affecting certain chemicals in the brain that are involved in controlling the sleep-wake cycle [2]. The active ingredient in armodafinil is armodafinil, which is the R-enantiomer of modafinil [3].
What is Armodafinil prescribed for?
Armodafinil is indicated for the treatment of excessive sleepiness associated with narcolepsy, obstructive sleep apnea (OSA), and shift work sleep disorder (SWSD) [1]. In patients with OSA, it is used as an adjunct therapy to continuous positive airway pressure (CPAP) or other primary treatments for the sleep disorder [1]. For SWSD, armodafinil is prescribed for individuals whose sleep disorder is associated with their work schedule [1].
How does Armodafinil work in the body?
The exact mechanism of action for armodafinil is not fully understood [1]. However, it is believed to selectively increase dopaminergic neurotransmission in the brain, primarily by inhibiting the reuptake of dopamine [4]. It may also affect other neurotransmitters, such as norepinephrine, serotonin, and glutamate [4]. These actions are thought to result in increased wakefulness and alertness [2].
What are the side effects of Armodafinil?
Common side effects of armodafinil can include headache, nausea, dizziness, insomnia, and nervousness [1]. Less common but more serious side effects can include severe skin reactions, such as Stevens-Johnson syndrome, and psychiatric symptoms like hallucinations or manic behavior [1]. Patients should report any unusual or severe side effects to their healthcare provider [1].
How long does Armodafinil stay in your system?
Armodafinil has an elimination half-life of approximately 10 to 12 hours [1]. This means that it takes about 10 to 12 hours for the body to eliminate half of the drug [3]. The drug can be detectable in the system for longer depending on factors such as individual metabolism and dosage [3].
When does Armodafinil's patent expire?
The patent landscape for armodafinil is complex, with various patents covering the drug and its uses [5]. DrugPatentWatch.com tracks these patent expirations. For specific details on patent expiry dates, consulting resources like DrugPatentWatch.com is recommended [5].
Can generics of Armodafinil be produced?
Once patents expire and regulatory hurdles are cleared, generic versions of armodafinil can be manufactured and marketed [5]. The availability of generic armodafinil would likely lead to lower medication costs [5].
