Modafinil Tablet, Brand Name : Modvigil, Medicine Type : Allopathic

Modafinil is an oral medication, often sold under the brand name Provigil, that is classified as a wakefulness-promoting agent. It is used to help people who experience excessive sleepiness stay awake and alert during the day. Modafinil is a controlled substance due to its potential for misuse and dependence.

Modafinil is FDA-approved for the treatment of excessive daytime sleepiness associated with:

• Narcolepsy: A chronic neurological disorder that affects the brain's ability to control sleep-wake cycles.

• Obstructive Sleep Apnea (OSA): It is used as an adjunctive treatment to help patients with OSA who still experience sleepiness despite using a primary treatment like a continuous positive airway pressure (CPAP) machine.

• Shift Work Sleep Disorder (SWSD): This condition affects people who work night, early morning, or rotating shifts and experience difficulty staying awake during their work hours and sleeping during their rest hours.

It is important to note that modafinil does not cure these conditions but helps manage the symptoms of daytime sleepiness. It is not approved for use as a replacement for adequate sleep.

The exact way modafinil works is not fully understood, but it is believed to act as a weak inhibitor of the reuptake of dopamine, a neurotransmitter in the brain that plays a key role in wakefulness and motivation. By increasing the amount of dopamine in the space between nerve cells, modafinil helps to promote a state of wakefulness. Unlike traditional -based stimulants, it has a different pharmacological profile and is thought to have a lower potential for abuse, although it can still produce psychoactive and euphoric effects.

Modafinil is available in oral tablet form, typically in 100 mg and 200 mg strengths. The dosage and timing of administration depend on the condition being treated:

• For narcolepsy and OSA, it is usually taken once a day in the morning.

• For SWSD, it is taken about one hour before the start of the work shift.

It can be taken with or without food.

Modafinil is generally well-tolerated, but like all medications, it can cause side effects. Common side effects include:

• Headache

• Nausea and upset stomach

• Nervousness or anxiety

• Insomnia

• Dizziness

• Back pain

More serious, though rare, side effects can occur. You should seek immediate medical attention if you experience:

• Serious Skin Reactions: These can include Stevens-Johnson syndrome, toxic epidermal necrolysis, or other severe rashes that may be accompanied by a fever, blistering, or peeling skin.

• Psychiatric Symptoms: New or worsening depression, anxiety, agitation, hallucinations, mania, or thoughts of suicide.

• Cardiovascular Effects: Chest pain, palpitations, or a rapid heart rate.

• Allergic Reactions: Swelling of the face, lips, tongue, or throat.

• Abuse Potential: Modafinil is a controlled substance. Patients should be assessed for a history of drug abuse, and use should be monitored, as it has the potential for dependence.

• Cardiovascular Conditions: Use with caution in patients with a history of heart disease, uncontrolled hypertension, or a recent heart attack.

• Psychiatric Conditions: It should be used with caution in patients with a history of psychosis, depression, or mania.

• Drug Interactions: Modafinil can interact with other medications, including hormonal birth control, causing it to be less effective. It is crucial to inform your doctor about all medications, vitamins, and supplements you are taking.
