Modacare 200 mg is a generic variation of Modafinil 200 mg prescribed in the treatment of certain sleep disorders such as narcolepsy, obstructive sleep apnea & shift work sleep disorder.

People work in night shift, when they drive or students can use this medicine if they are with sleep disturbance.


What is Modacare 200 mg?

Modacare 200 mg (generic Modafinil 200) is a wakefulness promoting medicine prescribed to promote wakefulness in people with daytime sleepiness due to narcolepsy, obstructive sleep apnea & shift work sleep disorder. It promotes wakefulness by acting on certain neurotransmitters in the brain. The active pharmaceutical ingredient (API) present in Modacare 200 mg is modafinil. Modafinil comes under the category of “stimulants.” It stimulates the Central Nervous System (CNS) to make the person consuming it more alert and awake.

Modafinil is a white, crystalline powder that is not soluble in water. Hence, it is only available in the form of oral tablets. The FDA approved it in 1998 for the treatment of narcolepsy. Obstructive sleep apnea and shift work sleep disorder were later approved. 

What are The Uses of Modacare 200 mg Tablets?

Modacare 200mg is an on-label medicine for the following disorders:


Narcolepsy is a disorder that causes excessive daytime sleepiness, resulting in a loss of productivity. Apart from this, a narcoleptic patient suffers from drowsiness, cataplexy, sleep paralysis, and hallucinations. It is unknown what exactly causes narcolepsy. However, according to research, the neurotransmitter hypocreatin-1 is found at low levels in narcoleptic patients. Hypocreatin-1 is responsible for wakefulness. 

Obstructive sleep apnea (OSA)

OSA affects the breathing of a person while they sleep. The breathing stops for at least 10 seconds and then resumes. This occurs as the muscles supporting the soft tissue collapse and block the throat airways. As a result, the patient wakes up gasping for air. Other symptoms of OSA are loud snoring, excessive daytime sleepiness, morning headaches, and dry mouth after waking up.

Shift work sleep disorder

This disorder is commonly observed in people working unconventional shifts. This is because the disease directly affects the circadian rhythm, i.e., the biological clock of the patient. Hence, these patients suffer from excessive sleepiness during their working hours and insomnia during their sleeping hours. Some of the symptoms are difficulty concentrating, irritability, moodiness, incomplete sleep, etc. 

Modacare 200mg is used to treat excessive daytime sleepiness, which is one of the symptoms of these disorders. It cannot treat the underlying illness, which requires supportive methods.

How does The Modacare 200 mg Tablet Work?

The active ingredient in Modacare 200mg is modafinil. This is the substance that is responsible for the wakefulness effect of this drug. The specific process by which modafinil works is unknown. However, studies performed on modafinil revealed that it acts on certain neurotransmitter systems.

Some studies show that modafinil acts on the dopamine transporter (DAT). This prevents the neurons from reabsorbing dopamine, thus increasing its concentration in the brain. Dopamine is responsible for controlling several functions, including wakefulness. It inhibits the activity of norepinephrine and melatonin, which induces drowsiness and sleep.

It is important to note that modafinil does not act on the dopamine receptors, which adds to its clinical significance. Due to its pharmacological profile, modafinil is less likely to cause substance abuse.

Apart from this, modafinil is also speculated to indirectly affect several neurotransmitter systems connected to sleep.
