Vilafinil 200 mg

Vilafinil 200 mg contains modafinil, a wakefulness-promoting drug that helps to decrease excessive daytime sleepiness. It is often used for conditions where it is difficult to stay awake such as narcolepsy, sleepiness related to obstructive sleep apnea and shift work sleep disorder. This is a tablet that’s designed to help you stay awake during the day but it’s not a traditional stimulant. Usually taken once a day, as directed by your healthcare professional. It acts on the pathways in the brain that regulate sleep and wakefulness. It also keeps you awake and decreases your need for sleep on important tasks. Use only under the supervision of a physician. 

Mechanism of action

• Vilafinil 200 mg helps maintain a balance between brain signals by slightly increasing stimulating activity and reducing calming (GABA) signals that promote sleep.
• It also activates orexin neurons in the brain. These are critical for keeping the body awake and regulating the sleep wake cycle.
• The medicine may cause histamine release which further promotes wakefulness and decreases the desire to sleep.
• In addition, it works by slowing the reabsorption of certain brain chemicals like dopamine and norepinephrine. This helps to lift their levels which can help to improve alertness and concentration.
