Modafinil is an awakefulness enchancing drug that was created for treatment of daytime sleep related disorders such as Narcolepsy. It seems to have benefits for cognition via increasing levels of stimulatory neurotransmitters in the brain, and is used recreationally as a smart-drug.

What does modafinil do?
Modafinil is unique in that it induces wakefulness without causing stimulation. This is in contrast to classic stimulants like caffeine, adderall, and ritalin, which provide wakefulness as a result of stimulation. Its use has become more and more prevalent because of its relatively benign profile. It provides many benefits with little to no side effects. Modafinil is used to enhance cognition, improve ADHD, improve cognition during sleep-deprivation, augment antidepressants, and as a mood enhancer.
Its main mechanism of action is unknown but it is known to act as a potent, but weak dopamine reuptake inhibitor. It’s also an alpha-1 adrenoceptor agonist.
How Modafinil Works?
The exact mechanisms of action of Modafinil in the body are unknown. Research has shown that this medication has effects on various neurotransmitters in the brain and central nervous system including Histamine, Dopamine, Epinephrine (Adrenaline), Norepinephrine (Noradrenaline), Serotonin, and Orexin (Hypocretin).
Taking Modafinil has been seen to raise histamine levels and and locomotor activity in the central nervous system. Modafinil’s effects are shown to wear off once the natural neuronal histamine concentration has been depleted by a powerful inhibitor. This runs counter to a similar drug called methylphenidate, which does not react in the same manner to fluoromethylhistidine, a histidine decarboxylase inhibitor.Modafinil, the drug’s main active component of the same name, has not yet been fully researched to the extent that could reveal all the principles behind the way it operates. Several studies have discovered that it works by altering the CNS levels of histamine in the human body.
Controlled studies on mice revealed that the drug makes its way into the orexinergic system. Orexin is a peptide that acts as a neurotransmitter and is involved in the regulation of sleep/arousal states and the maintenance of vigilance. Test subjects that lacked the appropriate neuron failed to react as expected, pointing out the utmost importance of orexin in these processes.
In research Modafinil has been seen to affect Dopamine and its signalling pathways. In a study that looked at many different pathways and their neurotransmitters, Modafinil was seen to affect the Dopamine transporter, acting as a Dopamine reuptake inhibitor. An additional study using PET scans in human patients saw that by occupying the Dopamine transporter sites, Modafinil significantly increased levels of Dopamine in the brain.
The Benefits of modafinil
Often touted as the limitless pill or NZT-48, modafinil is a drug that acts in a similar manner to caffeine. It mainly increases energy and decreases sleepiness, but a lot of users have found it to also enhance their cognition, focus, and more. In particular, productivity is often reported to be dramatically enhanced by modafinil. In short, modafinil can:
Increased wakefulness
Increased motivation
Improved mood
Increased task enjoyment
Improved focus
Enhanced working memory
Decreased fatigue
Prevents detriments to cognition during sleep-deprivation
Prevents rebound sleep following sleep-deprivation
How to take modafinil powder?
Modafinil should be taken early in the morning with or without food. You can take it right after you wake up. If this is your first time taking modafinil, you should start with a low dose to determine how strongly it effects you. A lot of people find 200 mg to be the ideal dosage, but some find 100 mg or even 50 mg to be more than enough. Others find that they need more than 200 mg to reap its benefits.
Don’t take modafinil every day as it can disrupt your sleep and/or cause tolerance to form.
The dosage of modafinil powder?
Standard dosages are 100-200mg, or perhaps 4mg/kg bodyweight, either taken in a sleep deprived state (if the user desires to not fall asleep) or taken first thing in the morning if the user does not wish to impair sleep.
Modafinil Uses and Benefits:
Modafinil has been shown to help people stay awake and active, as well as make their mind much clearer if their memory has been previously worsened by the onset of sleep deprivation.Studies have successfully shown a correlation between the use of this drug and retaining cognitive function in a healthy state against factors like a lack of sleep. However, not all of them could connect Modafinil to an improvement in psychomotor function in human test subjects.
Narcolepsy, Shift-Work Sleep disorder, and Sleep Apnea
Narcolepsy is a neurological condition that affects control of wakefulness and sleep. The condition causes excessive daytime sleepiness, and can even cause people to randomly faint and fall asleep throughout the day. The exact cause of narcolepsy is unknown, although there are several possibilities, and a strong link with certain genetic factors. Part of the mechanism is due to a loss of orexin releasing neurons in the brain.
In multiple double-blind placebo-controlled research studies, Modafinil has been seen to be an effective treatment for reducing daytime sleepiness in people with narcolepsy. Scores on the Multiple Sleep Latency Test and the Maintenance of Wakefulness Test are greatly improved using Modafinil over placebo. Nighttime sleep monitored during trials using polysomnography has been found to not be negatively affected using Modafinil compared to placebo.
Upon discontinuation of treatment, symptoms of narcolepsy were seen to return in patients to their baseline levels when not receiving treatment. There have not been reports of people developing withdrawal symptoms seen with other stimulants like amphetamines, and development of dependence does not seem to be an issue either. The most commonly reported adverse effect in studies of Modafinil for narcolepsy has been headaches, and the levels were not significantly greater than what was reported with placebo.
Researchers have therefore concluded that Modafinil is a generally well-tolerated treatment option for managing narcolepsy, and it most commonly prescribed for this original treatment purpose. Usage for other sleep disorders has grown as well, especially shift-work sleep disorder and obstructive sleep apnea/hypopnea syndrome.
Shift-work sleep disorder is a circadian rhythm disorder that occurs when people have jobs that they work during normal nighttime sleep periods. This can be people who consistently work the night shift of various jobs or those that have a rotating schedule that causes them to intermittently work night shifts. This is also seen in some people who work very long shifts, such as doctors.
Like narcolepsy, people with shift-work sleep disorder experience excessive daytime sleepiness. Additionally, they may experience insomnia when trying to sleep outside of normal sleep hours (i.e. during the daytime). If people are able to return to normal sleep patterns than symptoms will resolve themselves, however this is not an option for most people.
In one study, patients with shift-work sleep disorder were given either 200 mg of Modafinil or placebo before their shifts. Patients treated with Modafinil were seen to have a reduction in frequency and duration of attention lapses when tested on a vigilance test. A modest improvement in latency to sleep time was also seen.
However despite these improvements, patients continued to have some excessive sleepiness and impaired performance at night. Researchers have said that because of this residual sleepiness that still occurs that the development of even more effective treatments is necessary.
Obstructive sleep apnea/hypopnea syndrome (OSAHS) is a potentially serious disorder that occurs when the muscles supporting the tongue and soft palate in the mouth relax and cause the airway to be partially or completely blocked. Apnea refers to periods of total blockage and no breathing, while hypopnea refers to slow or shallow breathing that occurs with partial airway obstruction.
Symptoms of sleep apnea include loud snoring, observed periods of breathing cessation while sleeping, waking up choking, awakening with dry mouth and sore throat, morning headaches, and excessive daytime sleepiness.
Modafinil is therefore sometimes used as an adjunct therapy for treating the symptoms of sleep apnea. Its use is not to try and cure the disorder, but rather to improve the daytime sleepiness that often occurs due to the disrupted sleep patterns caused by breathing troubles at night. Multiple double-blind placebo-controlled research studies have shown that Modafinil significantly improves daytime sleepiness compared to placebo.
Attention Deficit disorder & Attention-Deficit Hyperactivity disorder
One of the most common off-label uses of Modafinil is for Attention Deficit disorder (ADD) and Attention-deficit Hyperactivity disorder (ADHD). Many people use Modafinil for these conditions because of the stimulant effect it has. Many user reviews online state that using Modafinil for ADHD helps them stay motivated and focused on the task at hand.
Other review also mention that Modafinil use doesn’t have some of the more serious negative side effects (e.g. anxiety, depression) experienced with traditional medication such as Adderall, Ritalin, dextroamphetamine, and dexmethylphenidate.
Multiple research studies have tested using Modafinil to manage ADHD in adults. Some studies compared Modafinil to a placebo, while others compared both Modafinil and conventional medications to placebo.
One study tested the effectiveness of Modafinil compared to the conventional drug dextroamphetamine. Patients who took either of the active medications were seen to have significantly improved scores on the DSM-IV ADHD Checklist when compared to placebo. The researchers concluded that Modafinil pills are a viable alternative to conventional stimulants in adults with ADHD.
A double-blind, randomized, placebo-controlled crossover study found that a 200 mg dose of Modafinil was able to produce a similar pattern of cognitive enhancement in patients with ADHD compared to healthy patients. The researchers concluded that Modafinil has potential as an alternative treatment therapy for ADHD compared to traditional stimulants.
Use of Modafinil in children for ADHD is not recommended at this time. A study conducted using a specific high dose form of Modafinil called Sparlon in children with ADHD ended with some serious negative side effects in a small number of the participants.
Stevens-Johnson syndrome is a rare and serious disorder of the skin and mucous membranes. Its primary symptoms are fever, fatigue, widespread skin pain, a red or purple spreading rash, and blisters on the mucous membranes of the mouth, nose, eyes, and genitals.
Multiple studies since that time have shown the efficacy and safety of Modafinil use in children for ADHD, however it is not approved for use in this group. Additionally, Modafinil is currently not approved by the FDA as a drug to treat ADD or ADHD in adults, and more research is still needed to determine its full effects on these disorders.
Symptoms of Fatigue in Depression and Multiple Sclerosis (MS)
One of the most commonly reported symptoms associated with chronic depression is fatigue. Even in patients who are successfully being treated with conventional antidepressants like Selective Serotonin Reuptake Inhibitors (SSRIs) and having improvement in other symptoms associated with depression, fatigue and excessive sleepiness can still persist.
Additionally, some patients do not respond as well as wanted to conventional medications, and the combination of those antidepressants along with Modafinil has been seen work in some cases.
Multiple double-blind placebo-controlled studies have looked at the Modafinil augmentation in patients with fatigue and sleepiness who are only partially responding to traditional SSRI treatment for depression. In three separate but similar studies, Modafinil was used as an adjunct treatment with SSRI antidepressants in patients who were partial responders or nonresponders to the SSRIs alone.
In all three trials, Modafinil was seen to significantly improve fatigue and sleepiness in patients in the short term (less than 6 weeks). The researchers concluded that Modafinil may be a useful adjunct treatment for some patients with depression, especially those with fatigue issues.
As seen in patients with depression, one of the most common symptoms associated with Multiple Sclerosis is fatigue. Less research has been done on patients with this condition, however what has been done is promising.
One study was a single-blind, phase 2, two center study that compared Modafinil to placebo in improving fatigue severity in patients with MS. The patients were first given placebo for weeks 1-2, then 200 mg Modafinil pills for weeks 3-4, 400 mg Modafinil pills for weeks 5-6, and then placebo again for weeks 7-9.
The investigators were not blind to treatment to ensure safety of the participants. To ensure unbiased results, efficacy of treatment was evaluated using self rating scales, the primary test being the Fatigue Severity Scale (FSS).
It was found that fatigue and daytime sleepiness was significantly improved using the 200 mg dose of Modafinil, compared to both the 400 mg Modafinil dose and the placebo. The researchers said it was unclear why the higher 400 mg dosage did not maintain the improvements seen with the 200 mg dosage, concluding that it may have been due to tolerance or possible dose-related adverse effects that masked any possible benefits on fatigue.
Overall the researchers concluded that Modafinil may be a well tolerated and effective treatment for improving fatigue and sleepiness in people with MS.
Nootropic Cognitive Enhancement Effects
Some of the most common off-label uses of Modafinil are using the drug as a nootropic drug for cognitive enhancement. Various people from university students to Wall Street bankers to entrepreneurs use Modafinil to improve memory, learning, focus, and attention span.
One review study that examined the findings of previous research studies found that Modafinil specifically shows improvement in working and episodic memory following use.
Another review concluded that Modafinil primarily improves cognitive function in relation to executive function, especially when planning and executing difficult and complex tasks.
One double-blind between-subjects research study looked at the potential cognitive enhancing effects Modafinil had on healthy adult males.
It was found that Modafinil use significantly enhanced the participants performance on various neuropsychological tests including visual pattern recognition, spatial planning, and a stop-signal reaction test. Conversely, responding to certain tests was seen to be decreased, suggesting that Modafinil may help inhibit impulsivity and improve response accuracy.
Similarly to user reviews found in online nootropic forums, participants in the study reported feeling more alert and attentive on Modafinil, and having improved energy levels.
More research is needed in this area to full determine the effects Modafinil may have on healthy individuals to improve cognitive abilities.
