What Is Adrafinil?
Adrafinil is a chemical that was first synthesized in the 1970s by French drug manufacturer Louis Lafon Laboratories . Adrafinil’s chemical name is diphenylmethyl sulfinyl-2-acetohydroxamic acid, and its proprietary name in France was Olmifon. Adrafinil was approved for sale as Olmifon in France in the 1980s and its intended use was to prevent sleepiness and improve vigilance and alertness in elderly patients .
As researchers continued to study adrafinil, they identified one of its main metabolites as modafinil . In one experiment where the effects of modafinil and adrafinil were compared, researchers concluded that modafinil was significantly more potent  and that adrafinil’s effect comes from modafinil. Scientists at Lafon ultimately pushed forward with research into this newly identified chemical.
Lafon Group eventually released modafinil under the proprietary name “Modiodal” In France in 1994. It proved to be extremely popular and quickly surpassed adrafinil in terms of popularity. In the battle between these wakefulness substances, modafinil ultimately prevailed and adrafinil fell into clinical disuse. The French medical authorities withdrew marketing permission for Olmifon citing safety concerns and its effects-to-benefits ratio, and the drug was voluntarily discontinued in 2011.
Although adrafinil is no longer commercially manufactured as a medicine, several companies continue to produce it as a research chemical. This leaves open the possibility for researchers to continue investigating adrafinil.
How Does Adrafinil Work?
As noted by Milgram et al., adrafinil’s mechanism of action is not yet fully understood but it is known to affect CNS function . It is composed of two main metabolites, CRL 40476 and modafinil, the latter of which has been extensively studied and is believed to account for many of the effects of adrafinil . Adrafinil is broken down (metabolized) into modafinil in the body , and the two chemicals have strikingly similar pharmacological effects .
Despite the amount of research, there is still also uncertainty around how modafinil works, but several theories have been put forth [5, 6, 7]. Given that modafinil is adrafinil’s main active metabolite, understanding this modafinil research is helpful in terms of understanding how adrafinil works.
Modafinil appears to upregulate dopamine
Dopamine is a neurotransmitter that is involved in feelings of pleasure and mood. Modafinil has a robust effect on upregulating dopamine [5, 6] and this may explain some of the effects that adrafinil has been shown to have with respect to reducing depression .
Modafinil appears to upregulate norepinephrine
Norepinephrine is a neurochemical that stimulates the sympathetic nervous system and increases arousal and alertness. It increases heart rate and triggers the release of glucose so your body has increased access to energy [6, 7].
Modafinil appears to influence other wakefulness chemicals
Modafinil appears to speed up the brain
Modafinil increases how quickly the brain uses energy, which helps create a sense of wakefulness and alertness .
In summary, while we do not yet have a full understanding of adrafinil’s mechanism of action, its clear efficacy as a vigilance-promoting agent likely comes from its active metabolite, modafinil .
We will now turn our attention to adrafinil's known benefits.
What Are Adrafinil’s Benefits?
Although adrafinil was synthesized before modafinil, it has been the focus of far less research. What little literature exists is mostly in French and is much more limited in scope and nature than modafinil research.
While adrafinil’s exact mechanism of action is not yet fully understood, modafinil is likely responsible for at least part of its effects . That’s why in this section, we will refer to modafinil research that we consider to be relevant.
Several research studies involving older French adults have found that adrafinil significantly improves alertness and vigilance [1, 8, 9]. Early research by Lafon found that Olmifon (adrafinil) increases wakefulness in elderly patients [8, 9]. Adarfinil’s main known benefit is that it acts as a vigilance-promoting agent and can help older adults who suffer from age-related difficulties related to alertness .
These findings are consistent with the modafinil research showing that the latter has a pronounced effect on alertness . A key difference between adrafinil and modafinil is that only modafinil has been tested in non-elderly populations, such as in one study involving sleep-deprived doctors .
Improved memory and learning
Adrafinil has been shown to have an effect on memory and learning in both animal and human studies. One study involving trained aged beagle dogs found that treatment with adrafinil produced “significant improvement in learning” compared with a placebo .
Several clinical trials in older adults demonstrated that adrafinil can improve performance on learning and memory tasks [8, 9]. The improvement was significantly greater than in control groups, suggesting that adrafinil was really responsible for the effect .
When Lafon released adrafinil as Olmifon in the late 1970s, the drug’s intended use was to reduce sleepiness in elderly patients, and it did so effectively [8, 9]. Several clinical studies have shown that adrafinil significantly improves self-reported ratings of fatigue compared to groups that took a placebo .
Some researchers have suggested that adrafinil may be a candidate treatment for depression because it seems to have a positive effect on mood in sleep-deprived elderly individuals . Participants in one study reported feeling less depressed, more sociable, and happier than control groups .
Having reviewed adrafinil’s main known benefits, let’s now examine what the literature says about the side effects and safety of this research nootropic.
Adrafinil Side Effects and Safety
If you’re curious about adrafinil’s side effects and wondering whether it is safe to use in your research, this is the section for you. As noted by Milgram et al., there have been six clinical trials involving adrafinil and they were all conducted in France and published in French. The collective result of these studies was that adrafinil was well-tolerated .
During the study conducted by Israel et al., three subjects suffered from nausea and dizziness but two were in the placebo group .
During the study by Kohler and Lubin, no mention was made of any secondary or side effects .
Milgram et al. cite another study by Defrance et al., involving 49 patients aged 65 or older, which found that three adrafinil treated subjects displayed increased agitation and aggression [16 in 1].
Another study by Fontan et al. found that two adrafinil patients reported dryness of the mouth [29 in 1].
Yet our best source of information about adrafinil’s side effects and safety comes from a Summary of Product Characteristics document published in French by Cephalon France (the company that acquired the Lafon Group) . This document states that the following groups should avoid taking Olmifon (adrafinil):
- Individuals who are pregnant or breastfeeding
- Children (individuals under 18 years old)
- Anyone using hormonal birth control
- Anyone at risk of conditions like diabetes or psychiatric disorders
- Anyone with a history of liver or kidney disease
The document also notes that some participants in clinical trials experienced the following adverse reactions as a result of taking adrafinil :
- Increased stress
- Irregular heartbeat
- Mouth dryness
- Stomach pain
- Skin irritation
- Liver issues
- Orofacial dyskinesia
Side effects appear to be dose-dependent, which means that the higher the dose of adrafinil ingested, the greater the risk of experiencing side effects. Choosing a lower dose range may help to reduce the chances of test subjects experiencing side effects.
In addition to the above, there are still two key considerations in relation to adrafinil’s side effects and safety:
1. Adrafinil has not been approved by the United States Food and Drug Administration. This means that the USFDA has not made a determination on its safety, and it cannot thus be marketed as a medicinal product in the United States.
2. The French medical authority (the National Agency for the Safety of Medicines and Health Products) had deemed Olmifon (adrafinil) to be safe for use as a prescription medication through 2011, at which point it withdrew marketing permission for Olmifon in France, citing a high risk-to-benefit ratio and the potential for adverse effects.
How Long Does Adrafinil Last?
According to the Cephalon France product summary, adrafinil is rapidly absorbed when taken on an empty stomach and has an absorption half-life of 12 min ± 3 min. Maximum plasma concentration is reached after 0.90 ± 0.2 h and adrafinil’s effects last between 6-12 hours, depending on the individual .
During the time when adrafinil was available as Olmifon, patients were prescribed 2-4 tablets per day (600-1,200 mg/d), and the dose could be divided with half taken in the morning and half at noon.
We’ll now turn our attention to the question of where adrafinil can best be sourced as a research chemical.

How To Take Adrafinil Properly
If you’re planning to conduct research involving adrafinil, you may want to know how best the nootropic should be administered to test subjects. According to Cephalon France’s product summary document, we know that elderly individuals were prescribed Olmifon for the treatment of alertness deficits . This document states that the recommended Olmifon dose was:
- 2 to 4 tablets (600 mg to 1200 mg) each day
- The total dose should be separated into two, with one taken in the morning and one taken at noon.
These instructions offer quite a lot of leeway so researchers can adjust the doses given to test subjects depending on how each individual responds to the drug. In fact, many informal reports list a starting adrafinil dose of 300 mg/day for cognitive enhancement effects.
Adrafinil holds potential as a nootropic, but we understand that not everyone reading this article is in a position to conduct adrafinil research. Here are two alternatives.
Curious about adrafinil alternatives? If so, this is the section for you.
If you’re researching nootropics or are designing an experiment involving adrafinil, you should be aware of two other nootropics known for their cognitive enhancement potential.
The most obvious adrafinil alternative is modafinil, which is arguably one of the most potent and well-researched nootropics in existence. Unlike adrafinil, there is plenty of research regarding modafinil’s effectiveness for wakefulness, increased attention, and cognitive enhancement [5, 6, 7]. However, modafinil is a prescription-only medication in the vast majority of countries, and should not be self-administered or used recreationally under any circumstances. Read here for more information about buying modafinil online.
Another powerful cognitive enhancer is called Neuro Peak, a widely available nootropic supplement. It’s made up of a blend of herbal supplements that each have nootropic benefits. Some of Neuro Peak’s ingredients include DMAE, Ginkgo biloba, and Bacopa monnieri. If you’re not a researcher and just a member of the general public looking for a daily-use nootropic, this is probably your best bet.
Beginner’s Guide to Adrafinil | Verdict
Adrafinil is a promising research chemical with an interesting history as a one-time prescription drug that has since fallen into clinical disuse. There is clear evidence that adrafinil offers vigilance-promoting benefits in elderly populations and may also have cognitive-enhancing potential.
