What is Nuvigil 150 mg?

Nuvigil is a nervous system “stimulant” that is used to promote wakefulness in individuals suffering from various sleeping disorders. It helps to battle daytime sleepiness and lack of energy and regulate the sleep cycle, which are the common symptoms of sleep disorders. The active ingredient used in Nuvigil is the substance “Armodafinil.”. Its chemical composition is C15H15NO2S.

Armodafinil, along with its enantiomer, i.e., S-modafinil, makes up the drug Modafinil. It belongs to the class of eugeroics. These are a class of drugs that promote wakefulness and mental alertness. It is also a non-amphetamine drug. (Amphetamines are similar stimulating drugs, but these can cause addiction and have a high potential for abuse. (Hence, their consumption is deemed illegal if used without a medical prescription.) As the name suggests, Nuvigil 150 mg contains 150 mg of armodafinil. This is the normal dosage that physicians prescribe to treat sleeping disorders.

What are the uses of Nuvigil 150 mg?

Nuvigil stimulates the nervous system and prevents unwanted sleep attacks. The diseases listed below have no known cure. The only treatments available are symptom relief and avoiding abrupt, disorder-specific episodes. Because of its ability to increase alertness, it is prescribed for the following conditions:

  1. Narcolepsy

Narcolepsy is characterized by excessive daytime sleepiness, drowsiness, and disruption of the sleep cycle. Severe symptoms like sleep paralysis and hallucinations affect some patients. The exact causes of narcolepsy are unknown. Several theories include changes in hormones, stress, swine flu or streptococcal infections, abrupt shifts in sleep patterns, and the use of the Pandemrix flu vaccination. Two forms of narcolepsy have been identified: Type 1 (NT1) and Type 2 (NT2), which depend on hypocretin-1 levels and are responsible for wakefulness. Low hypocretin-1 levels cause cataplexy, or sudden bursts of muscular loss, which is a NT1 characteristic. NT2 is characterized by narcolepsy symptoms that do not include cataplexy. Individuals with NT2 can progress to NT1.

  1. Obstructive Sleep Apnea (OSA)

OSA is characterized by irregular breathing patterns while sleeping. Apnea refers to the condition in which a person repeatedly starts and stops breathing while they are asleep. OSA results from the relaxation of the throat muscles supporting the soft tissue, which obstructs the airway and temporarily stops breathing. The symptoms of OSA consist of snoring, waking up at night due to dyspnea or choking, loss of energy in the morning, mood swings, etc. Causes of OSA include obesity, thicker neck circumference that tightens the throat, naturally narrow throat, alcoholism, smoking, etc. Due to disruption of sleep, the patients suffering from OSA struggle with daytime sleepiness and drowsiness.

  1. Shift Work Sleep Disorder

The shift work sleep disorder disrupts the circadian rhythm, i.e., the biological clock of the body. This condition is commonly observed in night shift workers and individuals working outside the traditional 9–5 time span. Indicator symptoms include excessive sleepiness during productive hours, insomnia, and disruption of the sleep cycle. The patient may suffer from complications such as mood swings, low productivity, a lack of energy, lowered testosterone levels, and substance abuse. Lifestyle changes play a major role in dealing with this condition. Typically, doctors also prescribe sleep-regulating drugs to treat this disorder.
