What Armodafinil Is

Armodafinil is a wakefulness-promoting medication.
It is related to modafinil but is the R-enantiomer, meaning it has a more stable and longer-lasting effect.

It is not an amphetamine, but it has stimulant-like effects.

🧠 What It’s Used For

Armodafinil is prescribed for conditions that cause excessive daytime sleepiness:

✔ Narcolepsy

Helps reduce sudden sleep episodes.

✔ Obstructive Sleep Apnoea (OSA)

Used when tiredness persists even after proper CPAP treatment.

✔ Shift Work Sleep Disorder (SWSD)

Helps people who work night shifts stay alert during working hours.

(These are the official medical indications in most countries.)

How It Works

Armodafinil stimulates the central nervous system by influencing pathways involving:

• Dopamine

• Norepinephrine

• Histamine

• Orexin (wakefulness system)

This leads to:

• Increased alertness

• Improved concentration

• Reduced fatigue

Effects can last 12–15 hours
