- modafinil
Interactions between your drugs
modafinil mirabegron
Applies to: modafinil and mirabegron
Coadministration with inducers of CYP450 3A4 and/or P-glycoprotein may decrease the plasma concentrations of mirabegron, which has been shown in vitro to be a substrate of the isoenzyme and efflux transporter. However, in vivo results indicate that these pathways may play a limited role in the overall elimination. In healthy study subjects, mirabegron peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by less than 50% when a single 100 mg dose of mirabegron was administered following multiple dosing of rifampin 600 mg once daily. No dosage adjustment is recommended when mirabegron is administered in combination with rifampin and probably other CYP450 3A4/P-gp inducers.

Drug and food interactions
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.

mirabegron food
Applies to: mirabegron
Food reduces the oral absorption and bioavailability of mirabegron. According to the product labeling, administration of a 50 mg tablet with a high-fat meal decreased mirabegron peak plasma concentration (Cmax) and systemic exposure (AUC) by 45% and 17%, respectively, whereas administration with a low-fat meal decreased mirabegron Cmax and AUC by 75% and 51%, respectively. In phase 3 clinical studies demonstrating both safety and efficacy, mirabegron was administered without regards to food content and intake. Therefore, mirabegron can be taken with or without food at the recommended dosage.
