How Provigil causes the desired effect in promoting wakefulness?
The primary working mechanism of Provigil is centered on the hypothalamic region. In fact, Provigil increases the levels of hypothalamic histamine considerably. It obstructs the action that takes place in the dopamine transporter. The resultant effect of which there is an increase in the synaptic concentrations of dopamine. In fact, it also acts on the monoamine. This action, in fact, highlights the fact that Provigil affects and impact the dopamine levels in the nucleus accumbens and striatum regions. It is supposedly believed that Provigil’s mechanism of action is dependent on Orexins. Orexins are nothing but brain peptides, which is otherwise known as hypocretins. Orexin neurons are generally found within the hypothalamus region. But then it is also scattered across other parts of the brain too. Provigil causes an impact in the levels of Orexins when it is attached to certain parts of the brain that are involved in regulating the wakefulness in the body. When these neurons get activated, there is an increase in the dopamine and norepinephrine levels. This, in turn, increases the histamine levels in the histaminergic tuberomammillary neurons. Provigil 200mg tablets are highly potent in a sense that it is known to elevate the levels histamine to a far greater extent upon administration of a single dose.
Why is Provigil called as a cognitive enhancer?

Provigil improves the performance ability of an individual while performing long and complex tasks. It also enhances the planning and decision-making skills.

In fact, many students opt to buy Provigil without prescription during their time of examination and consume so as to remain focused and attentive. Its brain enhancing effect removes fatigue and improves the cognitive functioning of the brain. Persons affected by schizophrenia can be well benefitted from this medication, as it enhances the cognitive functioning.

How Provigil offers relief from ADHD symptoms?
The potential of Provigil to treat ADHD has only been discovered in the recent past. Its working mechanism is in a way similar to other medications that treat ADHD. It stimulates the release of dopamine and norepinephrine into the brain.

How is Provigil absorbed in the body? What is the half-life of the medication?
Provigil is basically a 1:1 racemic compound, wherein its enantiomers exhibits varied pharmacokinetics. However, the enantiomers don’t interconvert. The elimination half-life of Provigil taken in multiple doses is 15 hours. Upon consuming 200-600 mg of Provigil in a day, its enantiomers exhibit linear kinetics. The steady states of R-modafinil and total modafinil are reached after two days of dosing. Provigil is absorbed right immediately from the body upon oral consumption. The bioavailability of oral administration and aqueous suspension is almost the same. The bioavailability of Provigil is not in any ways affected by food intake. However, it is said that the time taken to attain peak concentration might get delayed by an hour. In short, the bioavailability of Provigil is 80% greater than the consumed dose. Provigil is primarily eliminated through metabolism. It has been found that less than 10% of the consumed dose is excreted in an unchanged manner. The half-life range of Provigil is somewhere between 10-12 hours.
