Vilafinil 200 is a generic modafinil 200mg tablet developed to promote sustained wakefulness in individuals suffering from excessive daytime sleepiness (EDS) related to narcolepsy, obstructive sleep apnea (OSA), and shift work sleep disorder (SWSD). As a eugeroic (wakefulness-promoting) agent, Vilafinil 200 acts on the central nervous system to enhance alertness and cognitive endurance without the overstimulation or addiction potential seen with amphetamine-based stimulants. It works by targeting neurochemical pathways responsible for regulating the sleep-wake cycle, making it particularly effective for people whose quality of life or job performance is affected by fatigue, disrupted sleep, or circadian rhythm disturbances. Vilafinil 200 supports not only daytime functionality but also mood balance and sustained focus, offering a safe, long-duration energy boost. Its popularity extends beyond clinical settings, as it is often favored by shift workers, students, and professionals for its clean, long-lasting stimulation and minimal side effects when used responsibly under medical supervision.

- Sleep & Mental Health > Narcolepsy / Sleep Disorders Indicated for the treatment of narcolepsy, OSA, and shift work-related EDS. Enhances mental clarity, improves wakefulness, and helps restore cognitive efficiency without causing dependency or rebound sleepiness.

Modafinil’s primary mechanism involves selective inhibition of dopamine reuptake, resulting in higher dopamine availability in brain regions linked to motivation, vigilance, and memory. It also affects the hypothalamic wake-promoting system by stimulating orexin pathways, which are essential for maintaining alertness and regulating circadian rhythm. Unlike traditional stimulants that act indiscriminately on the nervous system, Vilafinil 200 delivers a smooth and focused cognitive lift, making it suitable for patients with medical sleep conditions as well as high-functioning individuals needing extended mental performance. The drug’s action is well-balanced, offering wakefulness without a crash or excessive stimulation.

Usual Adult Dose for Narcolepsy: → 200 mg orally once daily in the morning Although doses up to 400 mg/day have been tolerated, most clinical data show no significant benefit beyond 200 mg. In elderly patients, start with lower doses and monitor closely. Usual Adult Dose for Obstructive Sleep Apnea: → 200 mg orally once daily in the morning Used as adjunct therapy to manage residual sleepiness alongside CPAP or other OSA treatments. Avoid dosing late in the day. Usual Adult Dose for Shift Work Sleep Disorder: → 200 mg orally 1 hour before work shift Improves alertness and mental readiness for those working night shifts or rotating schedules.
