Drug Interaction Report

GENERALLY AVOID: Coadministration with lasmiditan may increase the plasma concentrations of drugs that are substrates of the P-glycoprotein (P-gp) and/or breast cancer resistance protein (BCRP) transporters. The proposed mechanism, based on in vitro data, involves decreased clearance due to inhibition of P-gp and BCRP by lasmiditan. The clinical relevance is unknown.

MANAGEMENT: Concomitant use of lasmiditan with drugs that are P-gp and/or BCRP substrates should be avoided when possible. If coadministration is required, patients should be carefully monitored for increased adverse reactions of these drugs and dosing adjusted as necessary.

Administration with food may reduce the bioavailability of maraviroc. According to the product labeling, coadministration of a 300 mg dose of maraviroc with a high-fat breakfast reduced maraviroc peak plasma concentration (Cmax) and systemic exposure (AUC) by 33% in healthy volunteers. However, no food restrictions were used in the clinical studies that demonstrated the safety and efficacy of maraviroc. Therefore, maraviroc can be taken with or without food at the recommended dosage.
