Interactions between your selected drugs
alprazolam ↔ dronedarone
Applies to:Xanax (alprazolam) and dronedarone
MONITOR: Coadministration with dronedarone may increase the plasma concentrations of drugs that are substrates of the CYP450 2D6 isoenzyme, CYP450 3A4 isoenzyme, and/or P-glycoprotein efflux transporter. The mechanism is decreased clearance via these routes due to inhibition by dronedarone. When given with the CYP450 2D6 substrates metoprolol and propranolol, dronedarone increased metoprolol systemic exposure (AUC) by 1.6-fold and propranolol AUC by 1.3-fold. Similarly, dronedarone coadministration led to 1.4- to 1.5-fold increases in the AUC of diltiazem, nifedipine and verapamil, which are CYP450 3A4 substrates. Dronedarone also increased the AUC of digoxin, a P-glycoprotein substrate, by 2.5-fold.
MANAGEMENT: Caution is advised if dronedarone must be used concomitantly with medications that are substrates of the CYP450 2D6 isoenzyme, CYP450 3A4 isoenzyme, and/or P-glycoprotein efflux transporter, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever dronedarone is added to or withdrawn from therapy.

Drug Interaction Classification
The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
| 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. |
