Are you tired during the day? Or do you suffer from sleep ailments? There are various prescription drugs available on the market to help you manage these problems. One such effective prescription drug is Modafinil 200 mg.

In this blog, we have discussed everything that one should be aware of about Modafinil. 

What is Modafinil?

Modafinil is a central nervous system stimulant that helps in the treatment of excessive daytime sleepiness associated with sleep disorders like narcolepsy, obstructive sleep apnea, and shift work disorders. 

The compound was developed in the 1970s by French neuroscientists Michel Jouvet and L. Lafon Laboratories in France. 

Modafinil belongs to the Schedule IV controlled substance, approved by the FDA in 1998. It is sold under brand names like modalert, modvigil, provigil, etc. [1].

What Are The Uses And Benefits Of Modafinil?

The clinical use of Modafinil is to treat excessive daytime sleepiness associated with sleep disorders like-

  •  Narcolepsy, which is a neurological disorder that causes irregularities in the sleep cycle,
  •  Obstructive sleep apnea is a sleep disorder that blocks the airways and causes fragmentation in the sleep cycle. This problem is generally seen among all age groups, where the frequency increases with age and obesity. One of the major symptoms of the disorder is snoring. 
  •  Shift work disorder is a disorder found among shift workers who work for non-traditional hours. This disorder causes irregularities in the sleep cycle and deactivation among the workers. 

Modafinil, as a nootropic, helps in the regulation of the sleep cycle.

Off-label Uses of Modafinil

Five important off-label uses of Modafinil are-

1. ADHD (Attention Deficit Hyperactivity Disorder) is a chronic neurological disorder that causes behavioral changes. One of the symptoms of the disorder is being overly active. 

2. Chronic Fatigue Syndrome is a disorder that is characterized by profound fatigue and sleep abnormalities. 

3. Modafinil helps with Depression, a condition associated with the elevation or lowering of a person’s mood. It negatively affects your mood and changes the way you think, behave, or act.

4. Jet lag is a sleep disorder that affects those who travel across multiple time zones. 

5. Modafinil for studying-  Modafinil increases memory, focus, and concentration. The medication helps students study and secure good marks in exams. 

Modafinil is effective in treating the symptoms of the above disorders. 

Modafinil Working Mechanism 

Modafinil, as a nootropic, effectively helps in increasing neurotransmitters (chemical messengers) like serotonin, thyroxin, orexin, histamine, and dopamine and decreasing the levels of  GABA, resulting in reduced sleepiness. 

Pharmacokinetics of Modafinil

Three simple steps are followed in the pharma-co-kinetics process-

1. The medication is readily absorbed after administration. 

2. The drug is then metabolized in the liver.

3. The tablet is then excreted by the kidneys through urine.

  • Modafinil starts working within 30 minutes after administration. 

However, the duration might vary from patient to patient depending on two basic factors- age and health conditions (kidney and liver dysfunction).

Modafinil takes 2-4 hours to reach its peak after administration.

  • The half-life (the amount of time required by a medicine to reduce its half from the body) of Modafinil is 12-15 hours. A total of 4-5 half-lives are required to be completely removed from the system.
  • Therefore, the effects of Modafinil last for about 60-75 hours [2].

Modafinil Dosage Regimen

Modafinil comes in dosage strengths of 100-200mg, and it might vary from person to person depending on factors like-

  •  Age (a lower dose is recommended for people over 65 years of age). 
  •  Health conditions (kidney and liver dysfunction).

However, the standard recommended dosage of Modafinil is 200mg/day for adults over 16 years old. The maximum dosage of Modafinil is 400mg/day. 

The dosage should be taken regularly at the same time of the day for better effectiveness; the doses are generally taken in the morning in order to avoid insomnia.

Missed Dose of Modafinil 

If you miss a Modafinil dosage, you can skip the missed dose and follow your normal dosage schedule.

Overdose of Modafinil

You should not double the doses; it might lead to an overdose [3].
