Interactions between your drugs

Moderate

modafinil ioflupane I-123

Applies to: modafinil and ioflupane I 123

MONITOR: Drugs that bind to the dopamine transporter with high affinity may interfere with the image obtained using ioflupane I-123, which also binds to the dopamine transporter. These drugs include amoxapine, amphetamine, benztropine, bupropion, buspirone, cocaine, diethylpropion, ketamine, mazindol, methamphetamine, methylphenidate, modafinil, pemoline, phencyclidine (PCP), phentermine, phenylpropanolamine, pipradrol, selegiline, sertraline, and trihexyphenidyl. Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) may increase or decrease ioflupane binding to the dopamine transporter. Whether discontinuation of these drugs prior to ioflupane I-123 administration may help to minimize potential interference is unknown.

MANAGEMENT: Clinicians using ioflupane I-123 should be aware of possible diagnostic interference by drugs that can compete for binding to the dopamine transporter.

Drug and food interactions

Minor

modafinil food

Applies to: modafinil

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.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
