The exact mechanism of action is not known yet. However, scientific data and studies have revealed that the Modafinil works on neurotransmitters which are responsible for the regulation of sleep and wake cycle. Modafinil buy online acts on certain neurotransmitters especially Dopamine and prevents its re-absorption back into the nerve cells that have produced it. This results in accumulation of dopamine within the brain region for longer time span. As long as the chemical stays in your brain, you stay awake and alert for that period of time.

For cognitive enhancement, the nootropic medicine works in the similar fashion along with nourishing the nerve cells. People buy Modafinil online to stay ahead of everyone and to achieve personal and professional.

You will be interested to know a little about the history of modafinil’s development and licensing, as well as how it influenced working people and students all over the world. The famous french neuroscientist and novator in healthcare and pharmaceutics, Michel Valentin Marcel Jouvet, invented this medicinal drug in cooperation with Lafon Laboratories. France approved Modafinil and allowed its prescription under the name Modiodal in 1994, and four years later the American Food and Drug Administration (FDA) gave a license to the new preparation to treat narcolepsy. Such sleeping ailments as obstructive sleep apnea/hypopnea and shift work sleep disorder, were approved by the FDA for modafinil treatment in 2003.

Modafinil is a dopamine increasing agent, and due to this mechanism of action, it is used off-label by students and white-collar workers as the nootropic drug. It was shown to improve memory, learning capacities, and executive functions. Modafinil was trialed for many purposes. Transhumanists tried to use this smart drug to widen the horizons of a human’s intellect. Military medics tested modafinil as an attention, concentration, and motivation enhancer. It was supposed to elevate such characteristics as alert reaction time, active attention to details, and the ability to make correct judgments and decisions in situations where a person has a lack of sleep.

Many sportsmen used Nuvigil as a drug that improved their energy and performance. In 2004, it was prohibited by the World Anti-Doping Agency. It was reported that modafinil increased the maximum time of exercising as well as decreases the perceived exertion. Other not licensed uses of modafinil include for attention deficit hyperactivity disorder, schizophrenia, weight loss, and cognitive impairments in patients who take chemotherapy. It did not show any effects in mood stabilization, appetite, or metabolism. Though the results in cognitive enhancement were more significant, the possible negative consequences, like adverse reactions and interactions with other drugs, did not allow medical authorities to approve those indications. Wakefulness promotion remains the only legal usage of modafinil.

Modafinil is subject to control as a schedule IV (C-IV) drug.

Produces psychoactive and euphoric effects, and alterations in mood, perception, thinking, and feelings similar to those observed with other CNS stimulants (e.g., amphetamines, methylphenidate), but current evidence indicates risk of abuse or misuse is lower with modafinil than with schedule II CNS stimulants (e.g., amphetamine, methylphenidate). (See Actions.)

Monitor patients closely during treatment for possible signs of misuse or abuse (e.g., incrementation of doses, drug-seeking behavior), particularly in those with history of drug or stimulant abuse (e.g., amphetamine, cocaine, methylphenidate).

You should not use modafinil if you have ever had an allergic reaction or skin rash while taking modafinil or armodafinil (Nuvigil).

Modafinil can cause skin reactions that may be severe enough to need treatment in a hospital. Stop taking this medicine and get emergency medical help if you have a skin rash or hives, blisters or peeling, mouth sores, trouble breathing or swallowing, fever, swelling in your legs, dark urine, yellowing of your skin or eyes, or swelling in your face.
