Interactions between your drugs

Moderate

darunavir revefenacin

Applies to: darunavir and revefenacin

GENERALLY AVOID: Coadministration of revefenacin with inhibitors of organic anion transporting polypeptide (OATP) 1B1 and/or 1B3 may increase systemic exposure to its active metabolite, which has been reported to be a substrate of the hepatic uptake transporters. No pharmacokinetic data are available, but increased anticholinergic adverse effects such as mydriasis, blurred vision, heat intolerance, fever, dry mouth, tachycardia, urinary retention, constipation, and glaucoma (onset or exacerbation) may occur. In study patients, revefenacin was rapidly converted to its active metabolite following inhaled administration, and plasma exposures of the metabolite exceeded those of revefenacin by approximately 4- to 6-fold. The activity of the metabolite at target muscarinic receptors is approximately one-third to one-tenth that of revefenacin and could potentially contribute to systemic antimuscarinic effects at therapeutic doses.

MANAGEMENT: Concomitant use of revefenacin with OATP 1B1 and/or 1B3 inhibitors is not recommended.

Drug and food interactions

Moderate

darunavir food

Applies to: darunavir

ADJUST DOSING INTERVAL: Food enhances the absorption and oral bioavailability of darunavir administered in combination with low-dose ritonavir. The mechanism is unknown. When administered with food, the peak plasma concentration (Cmax) and area under the plasma concentration-time curve (AUC) of darunavir were approximately 30% higher than when administered in the fasting state. Darunavir exposure was similar for the range of meals studied. The total caloric content of the various meals evaluated ranged from 240 Kcal (12 grams fat) to 928 Kcal (56 grams fat).

MANAGEMENT: To ensure maximal oral absorption, darunavir coadministered with ritonavir should be taken with food. The type of food is not important.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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.
Unknown No interaction information available.
