How does Modafinil work?
There are multiple theories explaining the working of Modafinil, however, the exact mechanism is not completely understood. What is known is that it does not have the same effect as other stimulants or ‘uppers’ like amphetamines or Ritalin. These substances, which directly stimulate the central nervous system, always have side effects like increased blood pressure, heart rate and nervousness. In the case of Modafinil, these side effects are less, which make it much more safe to be used regularly. Quitting Modafinil does not have any withdrawal effects, in contrast to amphetamines, Ritalin and even caffeine. The most widely accepted theory today is that Modafinil stimulates the blood flow to parts of the brain that is responsible for focus and cognition.
