This report displays the potential drug interactions for the following 2 drugs:
- armodafinil
- Cotempla XR-ODT (methylphenidate)
Interactions between your drugs
methylphenidate armodafinil
Applies to: Cotempla XR-ODT (methylphenidate) and armodafinil
In single-dose pharmacokinetic studies, healthy volunteers given modafinil (200 mg) with dextroamphetamine (10 mg) or methylphenidate (40 mg) exhibited a delay in the absorption of modafinil by approximately 1 hour. The mechanism of interaction is unknown. No other alterations in the pharmacokinetics of any of the drugs were observed. Although not studied, the interaction is likely to also occur with the various prodrug, racemic, and enantiomeric formulations of these drugs (e.g., amphetamine, lisdexamfetamine, dexmethylphenidate, armodafinil).

Drug and food interactions
methylphenidate food
Applies to: Cotempla XR-ODT (methylphenidate)
GENERALLY AVOID: Alcohol may exacerbate the adverse central nervous system effects of psychoactive drugs, including methylphenidate.
GENERALLY AVOID: Consumption of alcohol while taking certain sustained-release formulations of methylphenidate may cause rapid release of the drug, resulting in increased systemic levels of methylphenidate. In vitro studies have been conducted using Metadate CD 60 mg and Ritalin LA 40 mg capsules, as well as Concerta 18 mg tablet. At an alcohol concentration of 40%, an increase in the release rate of methylphenidate was observed in the first hour for Metadate CD and Ritalin LA, resulting in 84% and 98% of the methylphenidate being released, respectively. In contrast, there was no increased release of methylphenidate in the first hour for Concerta. These results are considered to be representative of the other available strengths of the corresponding product.
MANAGEMENT: Patients treated with methylphenidate should be advised to avoid alcohol or medications that contain alcohol.

armodafinil food
Applies to: armodafinil
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.

Therapeutic duplication warnings
Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
Stimulants
Therapeutic duplication
The recommended maximum number of medicines in the 'stimulants' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'stimulants' category:
- armodafinil
- Cotempla XR-ODT (methylphenidate)
Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.
Cerebral stimulants
Therapeutic duplication
The recommended maximum number of medicines in the 'cerebral stimulants' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'cerebral stimulants' category:
- armodafinil
- Cotempla XR-ODT (methylphenidate)
Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.
