🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionArmodafinil is well absorbed after oral administration. The absolute bioavailability is not known. Food does not significantly affect the absorption of armodafinil.
DistributionArmodafinil is widely distributed throughout the body. It is approximately 60% bound to plasma proteins, mainly albumin.
Protein BindingApproximately 60% bound to plasma proteins, primarily albumin.
MetabolismArmodafinil is metabolized in the liver, primarily by cytochrome P450 enzymes, including CYP3A4. The main metabolites are inactive.
Half-LifeThe elimination half-life of armodafinil is approximately 13 to 15 hours.
ExcretionArmodafinil and its metabolites are primarily excreted in the urine. Approximately 80% of the dose is excreted in urine, with less than 10% as unchanged drug.
BioavailabilityNot established from the available information.
Onset of ActionThe onset of wakefulness-promoting effects is typically within 1 to 2 hours after oral administration.
Peak Plasma TimeThe peak plasma concentration is reached approximately 2 hours after oral administration.
Duration of ActionThe wakefulness-promoting effect lasts for approximately 8 to 12 hours, depending on the dose and individual factors.

How It Works

Armodafinil is the R-enantiomer of modafinil. Its exact mechanism of action is not fully understood, but it is believed to promote wakefulness by inhibiting the reuptake of dopamine and possibly by affecting other neurotransmitters such as norepinephrine and serotonin. It does not act as a direct dopamine receptor agonist, but it increases extracellular dopamine levels by blocking the dopamine transporter. This leads to increased neuronal activity in areas of the brain that regulate sleep and wakefulness.

Mechanism Steps

1
Binding to dopamine transporter: Armodafinil binds to the dopamine transporter (DAT) in the brain and inhibits the reuptake of dopamine.
2
Increased dopamine levels: This inhibition leads to increased extracellular concentrations of dopamine in the synaptic cleft.
3
Stimulation of wake-promoting pathways: Elevated dopamine levels stimulate wake-promoting neurons in the hypothalamus and other brain regions.
4
Enhanced wakefulness: The overall effect is increased alertness and reduced excessive daytime sleepiness.

Dosage Information

Adult DosageThe usual adult dose of this medicine is 150 mg to 250 mg taken once daily in the morning. For narcolepsy and obstructive sleep apnea, the recommended dose is 150 mg to 250 mg once daily. For shift work sleep disorder, the recommended dose is 150 mg taken approximately 1 hour prior to the start of the work shift. The dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not exceed the prescribed dose.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageClinical studies of armodafinil did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Renal ImpairmentNo dose adjustment is required for patients with renal impairment. However, use with caution in patients with severe renal impairment.
Hepatic ImpairmentIn patients with severe hepatic impairment, the dose should be reduced. Consult your doctor for specific dosing recommendations.
Maximum Daily Dose250 mg per day.
