Vilafinil 400 mg

Vilafinil 400 mg contains modafinil. This medication is a central nervous system stimulant / wakefulness-promoting agent. It is used to manage excessive daytime sleepiness associated with sleep-related disorders such as narcolepsy, obstructive sleep apnea-hypopnea syndrome (OSAHS), and shift work sleep disorder (SWSD). This helps you to improve concentration, cognitive performance, and alertness without causing typical amphetamine-like stimulation. This develops energy, and you feel energetic in your work all day. 

MECHANISM OF ACTION 

Modafinil 400 mg influences the central nervous system by targeting several neurotransmitters (such as dopamine, serotonin, norepinephrine, gamma-aminobutyric acid, and glutamate). This medication increases the concentration of dopamine in the synaptic cleft by blocking the dopamine transporter (DAT). This enhances stimulation of postsynaptic dopamine receptors. This increase in dopaminergic activity is thought to be crucial for the wake-promoting effects of modafinil. As a result, people feel wakefulness in the daytime. 

KEY FEATURES

USES

• Narcolepsy: This is a type of sleep disorder that causes excessive daytime drowsiness. The affected person experiences excessive sleepiness, sleep paralysis, and hallucinations. In some cases, patients feel episodes of cataplexy, which is known as partial or total loss of muscle control. Vilafinil 400 mg stimulates the brain, keeping you fully awake and alert.  
• Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS): People experience physical airway blockage in OSAHS. It also relieves these abnormal symptoms and regulates the sleep cycle. After taking this medication, patients feel more energetic and will be able to perform better in their daytime activities. 
• Shift Work Sleep Disorder (SWSD): Circadian rhythms are physical, mental, and behavioral changes that follow a 24-hour cycle. SWSD is caused by circadian rhythm disorder. This medication improves cognitive functions, such as mental clarity, enhancement of memory, and problem-solving abilities.
