Pharmacology
Armodafinil is an indirect dopamine receptor agonist. This is the R-enantiomer of Modafinil which is a 1:1 mixture of the R- and S-enantiomers. Armodafinil binds to the dopamine transporter and inhibits dopamine reuptake. As a result, increases neuronal activity in the hypothalamus, enhances activity in hypothalamic wakefulness center (TMN, tuberomammillary nucleus) within the hypothalamic sleep wake switch.Dosage & Administration
Adults:- Obstructive Sleep Apnea & Narcolepsy: 150 mg to 250 mg as a single dose in the morning.
- Shift Work Disorder: 150 mg as a single dose approximately 1 hour prior to the start of work shift.
Children: Safety and effectiveness in pediatric patients less than 17 years of age have not been established.
Elderly: In elderly patients, elimination of Armodafinil and its metabolites may be reduced as a consequence of aging. Therefore, consideration should be given to the use of lower doses and close monitoring in this population.
Interaction
The clearance of drugs that are substrates for CYP3A4 or CYP3A5 (e.g., steroidal contraceptives, Cyclosporine, Midazolam and Triazolam) may be increased by Armoda which results in lower systemic exposure. Dosage adjustment of these drugs should be considered when used concomitantly with Armoda.Elimination of drugs that are substrates for CYP2C19 (e.g., Phenytoin, Diazepam, Propranolol, Omeprazole and Clomipramine) may be prolonged by Armoda which results in higher systemic exposure. Dosage adjustment of these drugs should be considered when used concomitantly with Armoda.
More frequent monitoring of prothrombin times/ International normalized ratio (INR) should be considered whenever Armoda is co-administered with Warfarin.
Caution should be used when concomitantly administering MAO inhibitors and Armoda.
Contraindications
Contraindicated in patients with known hypersensitivity to Armodafinil or any of theexcipients of this productOverdose Effects
There were no overdoses reported in the Armoda clinical studies. Symptoms of Armoda overdose are likely to be similar to those of Modafinil which included excitation or agitation, insomnia and slight or moderate elevations in hemodynamic parameters. There is no specific antidote for Armoda overdose. However, if overdose occurs, it should be managed with primary supportive care.Therapeutic Class
