Modvigil 200 mg (a generic form of modafinil) raises dopamine levels in the brain by inhibiting dopamine transporters, preventing reuptake. This leads to increased extracellular dopamine concentrations, which promotes alertness, mood improvement, and attention. Modvigil 200, unlike typical stimulants, is less likely to cause addiction due to its gentler action on dopamine pathways. It is commonly used to treat narcolepsy, sleep apnea, and shift work sleep disorder. Although effective, long-term usage may disrupt natural dopamine balance, thus it should only be taken under medical supervision to avoid reliance or negative effects.
