Mechanism of Action

modafinil’s exact mechanism of action is not fully understood, but it is believed to involve several neurotransmitter systems, including dopamine, norepinephrine, and orexin. The drug enhances the release of these neurotransmitters in specific areas of the brain, promoting wakefulness and alertness without the jittery side effects typically associated with classic stimulants (Tanda et al., 2021).

Pharmacokinetics

Modafinil is administered orally and is rapidly absorbed in the gastrointestinal tract. It reaches peak plasma concentrations within 2 to 4 hours post-ingestion. The drug has a half-life of approximately 15 hours, allowing for once-daily dosing in many cases. It is metabolized primarily in the liver through the cytochrome P450 system, with several metabolites being produced, but only modafinil itself is believed to be pharmacologically active (Reith et al., 2015).

Indications and Usage

Modafinil is indicated for the following conditions:

• Narcolepsy: A chronic sleep disorder characterized by excessive daytime sleepiness, often accompanied by sudden sleep attacks.
• Obstructive Sleep Apnea: A condition where breathing repeatedly stops and starts during sleep, leading to disrupted sleep patterns.
• Shift Work Sleep Disorder: A condition affecting individuals who work non-traditional hours, leading to sleep disruptions.

The drug is sometimes prescribed off-label for conditions like attention-deficit/hyperactivity disorder (ADHD), depression, and chronic fatigue syndrome, though more research is needed to solidify these uses.
