- Delsym 12 Hour Cough Relief (dextromethorphan)
Interactions between your drugs
dextromethorphan danicopan
Applies to: Delsym 12 Hour Cough Relief (dextromethorphan) and danicopan
MONITOR: Coadministration with danicopan may increase the plasma concentrations of drugs that are substrates of the efflux transporters breast cancer resistance protein (BCRP) and/or P-glycoprotein (P-gp). The proposed mechanism involves decreased clearance due to inhibition of BCRP and P-gp by danicopan. In clinical drug interaction studies, when subjects were coadministered the BCRP substrate rosuvastatin (single 20 mg dose) with danicopan at steady state (200 mg three times daily for 4 days), the peak plasma concentration (Cmax) and systemic exposure (AUC) of rosuvastatin increased by 3.3-fold and 2.2-fold, respectively. In addition, when the P-gp substrate fexofenadine (single 180 mg dose) was coadministered with danicopan (150 mg three times daily for 4 days), the peak plasma concentration (Cmax) and systemic exposure (AUC) of fexofenadine increased by 1.4-fold and 1.6-fold, respectively. Similarly, when subjects were coadministered the P-gp substrate tacrolimus (single 2 mg dose) with danicopan (200 mg three times daily for 5 days), the Cmax and AUC of tacrolimus increased by 1.1-fold and 1.5-fold, respectively.
MANAGEMENT: Caution and clinical monitoring are recommended if danicopan is coadministered with drugs that are substrates of the transporters BCRP and/or P-gp, particularly sensitive substrates, or those with a narrow therapeutic range. Dosage adjustments as well as closer clinical and laboratory monitoring for the development of adverse effects may be appropriate for some drugs whenever danicopan is added to or withdrawn from therapy. Individual product labeling should be consulted for further guidance.

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.
