Interactions between your drugs

Moderate

rifAMPin bempedoic acid

Applies to: rifampin and Nexlizet (bempedoic acid/ezetimibe)

MONITOR: Coadministration with bempedoic acid may increase the plasma concentrations and the risk of adverse effects of drugs that are substrates of the uptake transporters organic anion transporting polypeptide (OATP) 1B1 and 1B3. The proposed mechanism, based on in vitro data, is decreased clearance due to bempedoic acid-mediated inhibition of OATP1B1 and 1B3.

MANAGEMENT: Caution is advised if bempedoic acid is used concomitantly with drugs that are substrates of OATP1B1 or 1B3, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring should be considered whenever bempedoic acid is added to or withdrawn from therapy with these drugs. Patients should be monitored for the development of adverse effects.

Drug and food interactions

Moderate

rifAMPin food

Applies to: rifampin

GENERALLY AVOID: Concurrent use of rifampin in patients who ingest alcohol daily may result in an increased incidence of hepatotoxicity. The increase in hepatotoxicity may be due to an additive risk as both alcohol and rifampin are individually associated with this adverse reaction. However, the exact mechanism has not been established.

ADJUST DOSING INTERVAL: Administration with food may reduce oral rifampin absorption, increasing the risk of therapeutic failure or resistance. In a randomized, four-period crossover phase I study of 14 healthy male and female volunteers, the pharmacokinetics of single dose rifampin 600 mg were evaluated under fasting conditions and with a high-fat meal. Researchers observed that administration of rifampin with a high-fat meal reduced rifampin peak plasma concentration (Cmax) by 36%, nearly doubled the time to reach peak plasma concentration (Tmax) but reduced overall exposure (AUC) by only 6%.

MANAGEMENT: The manufacturer of oral forms of rifampin recommends administration on an empty stomach, 30 minutes before or 2 hours after meals. Patients should be encouraged to avoid alcohol or strictly limit their intake. Patients who use alcohol and rifampin concurrently or have a history of alcohol use disorder may require additional monitoring of their liver function during treatment with rifampin.

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.
