Modvigil 200mg

Modvigil 200 mg is a medicine that is used to help adults who are very sleepy because of certain sleep related conditions. Modvigil 200 mg contains the active ingredient modafinil. It is used to help reduce daytime sleepiness. It may help you have increased alertness while under medical supervision. Modafinil works in a more targeted way than stimulants that act on the central nervous system broadly. It is often chosen when a physician wants to treat sleepiness without producing strong sedation-rebound patterns or marked mental stimulation in many patients. 

Mechanism of action

• Modvigil 200 mg works by slowing the reabsorption of certain brain chemicals like dopamine and norepinephrine. This helps increase their levels which can improve alertness and focus.
• It also activates orexin (hypocretin) neurons in the brain. These play an important role in keeping the body awake and regulating the sleep-wake cycle.
• The medicine may increase histamine release, which further supports wakefulness and reduces the tendency to feel sleepy.
• In addition, it helps maintain a balance between brain signals by slightly increasing stimulating (glutamate) activity and reducing calming (GABA) signals that promote sleep.
