Modafinil is a medication that has been around since the 1970s, with its primary use in the treatment of narcolepsy daytime sleepiness and obstructive sleep apnea. It is now used as a cognitive enhancer to treat conditions such as ADHD or depression. Also, helps reduce sleepiness due to shift work sleep disorder.
There are various brand names for Modafinil UK; Modalert, Modvigil, Provigil, and Modafinil MD.
Clinical studies show it may also be effective in treating bipolar depression and cognitive impairments in those with Alzheimer’s disease.
The food and Drug Administration (FDA) has been working on the regulation of substances like Modafinil and armodafinil since they were first used in the late 70s.
It’s mainly used for these medical conditions but can also be used by healthy individuals to increase wakefulness and alertness every day without feeling tired. For people who experience anxiety or sleep deprivation due to night shifts, modafinil may also reduce their symptoms by giving them an added energy boost.
Mechanisms of Modafinil
The mechanism of action of drug Modafinil was discovered in the 70s when it was found to be a unique dopamine reuptake inhibitor (DRI) and glutamate reuptake inhibitor (GRi) in the central nervous. It works by blocking DAT, which is the enzyme that breaks down dopamine, to substantially raise dopamine levels in the brain.
Its mechanism works by entering the brain and interacting with DAT, which is believed to be the major carrier of dopamine in the brain. It blocks the transporter, which keeps dopamine from being deactivated by the enzyme that breaks it down. This buildup of dopamine causes a large release of dopamine in many neurotransmitter pathways across the brain (norepinephrine, serotonin, acetylcholine). The GABAergic neurotransmitters are also reduced in their levels due to this action.
Nucleus accumbens, the reward center of the brain, has a large variety of dopamine receptors. There are three different types of dopamine receptors: D1, D2, and D3. Modafinil works on two of these receptors (D1 and D2) by blocking the reuptake of dopamine from outside of the cells with its activity on DAT. This would make sense in the treatment for Parkinson’s disease, as increasing levels of dopamine may help treat the symptoms (elegant thinking).
The mechanism of action of Modafinil in the liver is not known. It has been shown to reduce hepatic drug metabolism through inhibition of cytochrome p450 enzymes, however this is not significant enough to be detected on drug-drug interactions tests. Some studies have shown that Modafinil may also reduce blood flow to the liver.
Modafinil Sulfone Metabolite
Modafinil is metabolized by multiple pathways, but the major pathway is sulfone conjugation which is done by CYP3A4 enzyme. Modafinil sulfone metabolite has been shown to possess even stronger activity than Modafinil itself at the DAT transporter.
It is formed from Modafinil in the liver and then excreted in urine. The major reason Modafinil sulfone is tested for on drug tests is because of its long half-life (15-38 hours) compared to the parent compound (7-9 hours). This means that it stays in your system longer than the parent compound and can be detected at lower concentrations.
People using modafinil to increase their cognitive abilities may have very high expectations. After all, it’s no secret that we have always loved our little pill, as this is what many people use to get their daily dose of energy. However, if you’re concerned about the side effects of this waking drug, here’s what you need to know.
Modafinil is recommended for short-term use only.
Although modafinil has been used by millions of people over the years (with success), it should be noted that there is currently no long-term data on its side effects. While there are very few instances in which a person has experienced adverse side effects while taking modafinil, this does not mean that it will not happen in the future.
While people who take modafinil for medicinal purposes typically do so for long-term use, the drug is recommended to be used only in short-term situations. For example, a doctor may recommend that a patient take it every time they have a night shift. However, this should not be the case when one has to continue using it daily.
There is simply no way of knowing what long-term ramifications this could have on the body. As such, anyone who takes modafinil long-term without consulting their doctor should never exceed their recommended dosage or change the frequency at which they take it for more than two consecutive weeks.
Taking more than the recommended dosage may cause unwanted side effects and adverse reactions. This will be considered drug abuse. Symptoms of overdose can be very serious, such as seizures, heart attacks, trouble breathing and strokes.
Common Side Effects of Modafinil
1. It can cause insomnia, anxiety, and sleep disruptions
Based on the reports of people who use modafinil as a cognitive enhancer, they find that it largely increases their wakefulness and alertness. This comes at the expense of their sleeping patterns.

However, this doesn’t mean people get headaches every time they take modafinil. On the contrary, some people use it without experiencing this side effect. Also, some people experience more headaches while using modaf
inil than they usually do when they try and sleep without it (which is hard to do).
3. Modafinil can also cause diarrhea or other stomach problems
Like any other medication, there are instances in which someone may experience nausea, stomach upset, or diarrhea when taking modafinil.

4. It can also cause mood swings
When people take modafinil, they often do so for the purpose of enhancing their productivity. Therefore, some may experience an increase in mood swings or anxiety.

6. Skin rashes and chest pain

Aside from this, there may also be instances where a person experiences chest pain when taking modafinil. This is usually because their heart has gotten used to receiving extra energy and is therefore working harder than usual.
