Flmodafinil Vs. Modafinil : A Comparative Analysis

Last updated on 25 Jun, 2024

In the comparative analysis of Flmodafinil Vs. Modafinil, Modafinil is the most preferred option by individuals, as Flmodafinil is not clinically approved and lacks research and clinical trials.

Flmodafinil and Modafinil both enhance cognitive functions and are well-known for their ability to treat daytime sleepiness associated with narcolepsy, obstructive sleep apnea, and shift work sleep disorders. 

This blog gives us a detailed comparison between both nootropics and helps you choose the best option for you. 

What Is Modafinil?

Modafinil is a novel wakefulness promoting drug that helps in treating excessive  daytime sleepiness associated with narcolepsy, obstructive sleep apnea, and shift work sleep disorder. It was developed in 1970 in France by neuroscientists Michel Jouvet and L. Lafon. 

The nootropic primarily works in the hypothalamus of the brain by increasing chemical neurotransmitters such as orexin, histamine, dopamine and serotonin and helps in increasing cognition and focus. Modafinil belongs to the Schedule IV controlled substance and was approved by the FDA in 1998. 

The standard recommended dosage of Modafinil is 200mg/day for adults above 17 years old. The nootropic starts working within 30 minutes after administration. 

Flmodafinil: An Overview

CRL-40,940 or Flmodafinil, is a newer and modified version of Modafinil. It is manufactured by the same company but with a modification that enhances its effectiveness. Flmodafinil contains additional features such as fluoride groups, increasing it’s efficiency in smaller groups. However, the use of Flmodafinil is not approved clinically due to lack of clinical trials and research. 

The nootropic was patented in 2013, and pre-clinical trials have been underway since December 2015.

Efficacy In Enhancing Focus And Productivity


There are many users and studies that significantly report that Modfainil helps in enhancing focus, motivation and energy, making it a popular choice among students, professionals, and individuals with cognitively demanding lifestyles. 

A study by  M. Alexandra Kredlow in 2019 stated Modafinil as an effective cognitive enhancer for sleep deprived individuals. 

Flmodafinil is less researched, but some users suggested that it enhances bioavailability and might decrease the chances of side effects associated with Modafinil, such as headaches, nausea, or vomiting. 

Comparison Between the Pharmacological Profiles 

Both the nootropics  Modafinil and Flmodafinil share a common working mechanism that involves the inhibition of dopamine reuptake, which helps to increase the concentration of  orexin, histamine, serotonin and dopamine in the brain. These neurotransmitters are vital for regulating sleep-wake cycles and enhancing cognitive alertness. 

However, Flmodafinil is believed to have a higher bioavailability, which  theoretically results in more pronounced effects with a lower dosage.

Legal Considerations

Modafinil is a prescription medication and its legal status is quite established, belonging to the schedule IV controlled substance. It is approved in countries such as the United States, Australia, UK, and Canada.  To know more about Modafinil legality, you can check the blog "IIs Modafinil a Controlled Substance?”

 Whereas, Flmodafinil  exists in a grey area, is not approved by any regulatory body and is available through online vendors as a research chemical. This raises questions about ethical values to  people who self-medicate. 

Users must consider the legal implications, and safety of sourcing medications online. One should also consider the safety issue, and the quality and purity of such products can vary.

Modafinil is best suited for individuals dealing with sleep-related disorders. It is the best suited option for people who have access to prescription and is legal in many countries. 

Conversely, Flmodafinil is a possible potent option for people as it is effective at lower dosage. However, there is a lack of clinical data and trials .

Our Final Verdict

On the other hand, Flmodafinil , though a promising option, still needs to be fully understood and researched. The users must notice and weigh down the potential risks and benefits and consider the legal and ethical implications before buying a medication.
