Product Overview
Modvigil 200 mg is a wakefulness-promoting agent indicated for the treatment of excessive daytime sleepiness. It contains Modafinil, a eugeroic (wakefulness enhancer) that is commonly used to improve alertness and reduce fatigue in individuals affected by specific sleep disorders. Modvigil is recognized for its milder stimulant properties and lower risk of dependency compared to traditional stimulants like amphetamines.
Indications
Modvigil 200 is prescribed for the treatment of:
- Narcolepsy – sudden and uncontrollable episodes of sleep
- Obstructive Sleep Apnea (OSA) – as an adjunct to continuous positive airway pressure (CPAP) therapy
- Shift Work Sleep Disorder (SWSD) – for individuals experiencing excessive sleepiness during work hours
Mechanism of Action
Modafinil promotes wakefulness by selectively influencing several neurotransmitter systems in the brain. Its primary action involves inhibiting the reuptake of dopamine, thereby increasing dopamine levels in the central nervous system. It also modulates norepinephrine, serotonin, histamine, and orexin—contributing to heightened alertness, improved mood, and enhanced cognitive performance.
Dosage and Administration
- Standard Dose: 200 mg once daily
- For Narcolepsy & OSA: Taken in the morning
- For SWSD: Taken about 1 hour before the work shift
- Route: Oral, with or without food
- Hepatic Impairment: Recommended dose reduction (100 mg/day)
Always follow your physician’s instructions for dosage and duration.
