Armod
Armod Uses, Dosage, Side Effects, Food Interaction and all others data.
Armod is a preparation of Armod which is an indirect dopamine receptor agonist. Armod is the R-enantiomer of Modafinil which is a 1:1 mixture of the R- and S-enantiomers. Armod binds to the dopamine transporter and inhibits dopamine reuptake. As a result, Armod increases neuronal activity in the hypothalamus, enhances activity in hypothalamic wakefulness center (TMN, tuberomammillary nucleus) within the hypothalamic sleep wake switch.

Uses
Armod is used to improve wakefulness in adult patients with Obstructive sleep apnea (OSA). Narcolepsy Shift work disorder (SWD).
Armod is also used to associated treatment for these conditions: Narcolepsy, Shift-work related sleep disturbance, Somnolence
How Armod works
Nuvigil (armodafinil) is a single-isomer of modafini. The exact mechanism of action is unknown. Armod belongs to a class of drugs known as eugeroics, which are stimulants that provide long-lasting mental arousal. Pharmacologically, armodafinil does not bind to or inhibit several receptors and enzymes potentially relevant for sleep/wake regulation. Armod is not a direct- or indirect-acting dopamine receptor agonist. However, in vitro, both armodafinil and modafinil bind to the dopamine transporter and inhibit dopamine reuptake. [Medilexicon]
Dosage
Armod dosage
Adults: Obstructive Sleep Apnea (OSA) & Narcolepsy: 150 mg to 250 mg as a single dose in the morning. Shift Work Disorder (SWD): 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 Armod 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. Patients with hepatic impairment: In patients with severe hepatic impairment, Armod should be administered at a reduced dose. Patients with renal impairment:There is inadequate information to determine safety and efficacy of dosing in patients with severe renal impairment.
Side Effects
The most common side effects of Armod are serious rash, including Stevens-Johnson syndrome, angioedema and anaphylaxis reactions, multi-organ hypersensitivity reactions, persistent sleepiness, psychiatric symptoms and some cardiovascular events.
Precaution
Patients should be cautioned about operating an automobile or other hazardous machinery until it is reasonably certain that Armod therapy will not adversely affect their ability to engage in such activities. Caution should be taken in treating patients with a history of psychosis, depression or mania. Discontinuation of treatment should be considered if psychiatric symptoms develop. Increased monitoring of heart rate and blood pressure should be exercised. Caution should be exercised when prescribing Armod to patients with known cardiovascular disease.
Interaction
The clearance of drugs that are substrates for CYP3A4 or CYP3A5 (e.g., steroidal contraceptives, Cyclosporine, Midazolam and Triazolam) may be increased by Armod which results in lower systemic exposure. Dosage adjustment of these drugs should be considered when used concomitantly with Armod.
Elimination of drugs that are substrates for CYP2C19 (e.g., Phenytoin, Diazepam, Propranolol, Omeprazole and Clomipramine) may be prolonged by Armod which results in higher systemic exposure. Dosage adjustment of these drugs should be considered when used concomitantly with Armod.
More frequent monitoring of prothrombin times/ International normalized ratio (INR) should be considered whenever Armod is co-administered with Warfarin.
Caution should be used when concomitantly administering MAO inhibitors and Armod.
Food Interaction
- Avoid alcohol.
- Exercise caution with grapefruit products. Armod is partially metabolized by CYP3A4, and grapefruit is a CYP3A4 inhibitor.
- Exercise caution with St. John's Wort. Armod is partially metabolized by CYP3A4, and St. John's Wort is a CYP3A4 inducer.
- Take with or without food. Taking armodafinil with food can delay the Tmax by 2-4 hours.
[Minor] Administration with food may delay the absorption of modafinil (the racemate) and armodafinil (the R-enantiomer) without significantly affecting their overall bioavailability.
According to the product labeling, modafinil's absorption may be delayed by approximately one hour if taken with food.
Similarly, the time to reach peak plasma concentration (Tmax) of armodafinil may be delayed by approximately 2 to 4 hours in the fed state.

Minor: aripiprazole, aripiprazole, amphetamine / dextroamphetamine, amphetamine / dextroamphetamineUnknown: duloxetine, duloxetine, omega-3 polyunsaturated fatty acids, omega-3 polyunsaturated fatty acids, pregabalin, pregabalin, cyanocobalamin, cyanocobalamin, ascorbic acid, ascorbic acid, cholecalciferol, cholecalciferol, bupropion, bupropion, cetirizine, cetirizine
Armod Disease Interaction
Moderate: alcoholism, cardiovascular dysfunction, liver dysfunction, psychiatric complications, bipolar disorders, psychotic disorders
Volume of Distribution
Apparent volume of distribution: 42L.
Elimination Route
Tmax is 2 hours when fasted and can be delayed approximately 2-4 hours by food, potentially affecting the onset of action.
Half Life
Terminal half-life is approximately 15 hours.
Clearance
The oral clearance of armodafinil is approximately 33 mL/min.
Pregnancy & Breastfeeding use
Pregnancy: There are no adequate and well controlled studies of Armod in pregnant women. Armod should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Lactation: It is not known whether Armod or its metabolites are excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Armod is administered to a nursing woman.
Contraindication
Contraindicated in patients with known hypersensitivity to Armod or any of theexcipients of this product.
Special Warning
Patients with hepatic impairment: In patients with severe hepatic impairment, Armod should be administered at a reduced dose.
Patients with renal impairment:There is inadequate information to determine safety and efficacy of dosing in patients with severe renal impairment.
Acute Overdose
There were no overdoses reported in the Armod clinical studies. Symptoms of Armod 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 Armod overdose. However, if overdose occurs, it should be managed with primary supportive care.
Interaction with other Medicine
The clearance of drugs that are substrates for CYP3A4 or CYP3A5 (e.g., steroidal contraceptives, Cyclosporine, Midazolam and Triazolam) may be increased by Armod which results in lower systemic exposure. Dosage adjustment of these drugs should be considered when used concomitantly with Armod. Elimination of drugs that are substrates for CYP2C19 (e.g., Phenytoin, Diazepam, Propranolol, Omeprazole and Clomipramine) may be prolonged by Armod which results in higher systemic exposure. Dosage adjustment of these drugs should be considered when used concomitantly with Armod. More frequent monitoring of prothrombin times/ International normalized ratio (INR) should be considered whenever Armod is co-administered with Warfarin. Caution should be used when concomitantly administering MAO inhibitors and Armod.
