Interactions between your drugs

Major

tipranavir nintedanib

Applies to: tipranavir and nintedanib

GENERALLY AVOID: Coadministration with inducers of P-glycoprotein (P-gp) and CYP450 3A4 may decrease the plasma concentrations of nintedanib, which is a substrate of the efflux transporter and a minor substrate of the isoenzyme. In a dedicated drug interaction study, administration of nintedanib with the potent P-gp and CYP450 3A4 inducer, rifampin, decreased nintedanib peak plasma concentration (Cmax) and systemic exposure (AUC) by 40% and 50%, respectively, compared to administration of nintedanib alone. No data are available for use with other, less potent inducers.

MANAGEMENT: Concomitant use of nintedanib with P-gp and CYP450 3A4 inducers should generally be avoided due to the potential for reduced efficacy.

Drug and food interactions

Moderate

tipranavir food

Applies to: tipranavir

ADJUST DOSING INTERVAL: Food does not appear to substantially alter the pharmacokinetics of tipranavir. When tipranavir capsules or oral solution was coadministered with ritonavir capsules at steady-state, no clinically significant changes in tipranavir peak plasma concentration (Cmax) and systemic exposure (AUC) were observed under fed conditions (500 to 682 kcal, 23% to 25% calories from fat) relative to fasted conditions. The effect of food on tipranavir exposure during coadministration with ritonavir tablets has not been evaluated. High-fat foods may enhance the gastrointestinal absorption of tipranavir. In a multiple-dose study, administration of tipranavir capsules with a high-fat meal (868 kcal, 53% from fat, 31% from carbohydrates) increased the oral bioavailability of tipranavir by 31% compared to administration with toast and skimmed milk, but did not significantly affect tipranavir Cmax. Thus, tipranavir may be safely taken with standard or high-fat meals.

MANAGEMENT: Tipranavir coadministered with low-dose ritonavir should be taken with food to improve the gastrointestinal tolerability of ritonavir. According to the product labeling, tipranavir coadministered with ritonavir capsules or solution can be taken with or without meals, whereas tipranavir coadministered with ritonavir tablets must be taken with meals.

Moderate

nintedanib food

Applies to: nintedanib

ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of nintedanib. After food intake, nintedanib exposure increased by approximately 20% compared to administration under fasted conditions. Absorption was also delayed, as indicated by an increase in the median time to reach maximum plasma concentration (Tmax) from 2 hours in the fasted state to approximately 4 hours under fed conditions, irrespective of the type of food ingested.

MANAGEMENT: Nintedanib should be administered with food.

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.
