- trospium / xanomeline
- vinorelbine
Interactions between your drugs
vinorelbine xanomeline
Applies to: vinorelbine, trospium / xanomeline
MONITOR: Xanomeline may increase the concentration of sensitive oral CYP450 3A4 substrates and/or narrow therapeutic index (NTI) oral P-glycoprotein (P-gp) substrates. In vitro data suggest that xanomeline may transiently inhibit CYP450 3A4 and P-gp locally in the intestine after dosing. Xanomeline does not appear to inhibit CYP450 3A4 and/or P-gp systemically. Clinical data evaluating this interaction are not available.
MANAGEMENT: Caution and clinical monitoring are advised if xanomeline is used in combination with an orally administered CYP450 3A4 sensitive substrate and/or NTI P-gp substrate for which a small change in substrate plasma concentration could lead to serious toxicities. The labeling of the substrate may be consulted for specific monitoring and dose adjustment recommendations should adverse reactions result from this combination.

Drug and food interactions
trospium food
Applies to: trospium / xanomeline
ADJUST DOSING INTERVAL: Food may reduce the oral absorption and bioavailability of trospium chloride. According to the product labeling, administration of trospium chloride with a high fat meal reduced the peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) by 70% to 80% compared to administration while fasting.
MANAGEMENT: To ensure maximal oral absorption, trospium chloride should be administered at least 1 hour before meals or on an empty stomach. If trospium chloride is administered as a combination with xanomeline, the manufacturer recommends administering the capsules at least 1 hour before a meal or at least 2 hours after a meal. Capsules should be taken whole.
