Modafinil mainly works by affecting several neurotransmitters in the brain, such as orexin, glutamate, dopamine, serotonin, and norepinephrine, among others, that promote wakefulness and improve cognitive functions.
Scientists are researchers have been meticulously trying to uncover the Modafinil Mechanism Of Action. Most of their findings are covered in medical and science journals, resulting in users being aware of how they really work.
Developed by Michel Jouvet and Lafon laboratories' Modafinil is a well-tolerated eugeroic, and it was the 302nd most frequently prescribed drug in the United States, with over 1,000,000 prescriptions written.
In this context, we will explore how Modafinil works to understand the science that contributes to its cognitive and wakefulness-promoting properties.
Modafinil - An Overview
Modafinil is marketed as a smart drug and is also known as a wakefulness-promoting agent or eugeroic.
Doctors prescribe Modafinil to treat excessive sleepiness associated with narcolepsy, shift work sleep disorder, and obstructive sleep apnea. Apart from its FDA-approved benefits, it has various off-label benefits as well.
Some of its off-label benefits include - Cancer and multiple sclerosis-related fatigues, treatment for cocaine addiction, attention deficit disorder, and improvement in cognitive function.
It was developed in the 1970s and approved in the United States for medical use in 1998 .
It is important to understand how Modafinil works because it can help you conceptualize how the smart drug could support your recovery and make you feel better. It will also make you aware of the side effects of the drug so that you do not panic when you suffer from the after-effects of the nootropic.
How Does Modafinil Work?
Modafinil is a drug with multiple actions, and this is because it works on various neurotransmitters in the brain - Sahakian . This nootropic works by changing the amounts of natural substances known as neurotransmitters in the areas of the brain that are responsible for controlling the sleep-wake cycle .
What Does Modafinil Do To The Brain- The Relationship Between Modafinil And Dopamine Receptors
The wake-promoting effects of Modafinil are notably different from those of other psychostimulants, such as amphetamine.
Modafinil is a weak dopamine reuptake inhibitor through its competitive binding to the cell membrane dopamine transporter (DAT). Its binding affinity is less than that of bupropion (an antidepressant). This interaction with the dopamine transporter and the subsequent increase in dopaminergic tone is responsible for wakefulness-promoting effects.
It has no effect on dopamine receptors, directly or indirectly.
Modafinil also binds similarly to the norepinephrine transporter (NET) and has additional effects on other CNS systems like GABA, Histamine, and glutamate .
Modafinil And Other Neurotransmitters
The smart drug raises serotonin and norepinephrine levels, which help regulate mood and mental arousal, or alertness in the brain.
The Modafinil neurotransmitter pathway in the brain includes glutamate and orexin. These pathways regulate a person's cognitive function, attention, and wakefulness.
The Half-Life Of Modafinil
The half-life of medicine typically refers to the period of time required by a drug to reduce to half.
The Modafinil elimination half-life ranges from 10 hours to 12 hours for most patients but can last up to 15 hours for some individuals.
Factors Affecting Modafinil Half-life
Certain factors, such as age, and poor kidney and liver function, can slow down the Modafinil metabolism and can increase the duration of its effects.
How Is Modafinil Metabolized In The Body?
Modafinil undergoes hepatic metabolization via multiple pathways and is assisted by the CYP3A4 enzyme, and its inactive metabolite is excreted in the urine. Urinary excretion of the drug (unchanged) ranges from 0 to 18.7%, depending on various factors.
Renal excretion of unchanged Modafinil accounts for around 10% or less of an oral dose. Two major metabolites of this drug are Modafinil sulfone and Modafinil acid. Both of these metabolites are inactive and do not contribute to the eugeroic or wakefulness-promoting effects of Modafinil.
Peak levels, also known as the Cmax of the stimulant, occur between 2 and 3 hours after its administration. Food can slow down the absorption of Modafinil.
In vitro measurements indicate that 60% of the drug is bound to plasma proteins at clinical concentrations of the drug. When the concentration of Modafinil changes, this percentage can change but at very low levels.
How To Make Modafinil Work Better?
To make Modafinil work better or to enhance its potency, one can follow the points mentioned below.
By increasing the dosage- The standard Modafinil dosage recommended is 200 mg. But if you are taking a lower dose, then it may be a reason for not experiencing the desired results. People already taking 200 mg of Modafinil should make any change in their dose after consulting a doctor.
Try split dosage- Another effective way to make Modafinil last longer is by splitting the standard 200 mg dosage in half. You can do the first half (100 mg) in the morning and the second half (100 mg) in the afternoon. This increases the absorption rate of Modafinil, thus making it last longer.
Taking Coffee- Mixing Modafinil with Coffee is a great idea. Both being brain stimulants help in enhancing the effectiveness of Modafinil.
Modafinil And Cognitive Function
Some recent behavioral studies have shown that Modafinil can enhance cognitive functions in domains like memory, executive functions, and attention, increasing alertness and response accuracy .
Dr. Ruairidh Battleday and Dr. Anna-Katharine Brem from the University of Oxford reviewed all research papers from January 1990 to December 2014 on cognitive Enhancement with Modafinil (Modalert). They found 24 studies addressing the various benefits of taking eugeroic for learning, planning, and decision-making, as well as for memory, flexibility, and creativity .
In a 2017 study, researchers monitored 60 participants, either a single dose of Modafinil 200 mg or a placebo, for changes in their cognitive function. Drawing conclusions from both neurocognitive tests and the participants, the researchers found that the modafinil group performed significantly better on episodic memory and working memory tests .
Unlike some nootropics, there is some good evidence to back up the effects of the smart drug Modafinil.
Modafinil has been shown to improve mood and increase resistance to fatigue .
In a review, it was found that Modafinil improves motivation, vigilance, and reaction time in healthy adults .
Modafinil is effective at reducing poor decisions or impulsive actions, according to another study by the University of Cambridge .
Modafinil Mechanism Of Action- Our Final Thoughts
This blog sheds light on how the potent and popular Nootropic Modafinil works.
The following are some key points from this blog:
Modafinil is known as a smart drug because of its ability to improve cognitive functioning.
It works by affecting neurotransmitters (Chemical messengers) such as dopamine, serotonin, orexin, and others.
The half-life of this drug is 10-12 hours for most people.
The onset of action of Modafinil is 30 minutes.
The effects of Modafinil 200 mg last for about 12 hours.
However, it is crucial to use the Nootropic after consulting a healthcare professional. If you are intrigued by the medical benefits of Modafinil and wish to give it a try, you can choose online pharmacies like Healthmatter to get affordable and genuine Modafinil online in a few clicks.
