Interactions between your drugs

Moderate

eluxadoline voxilaprevir

Applies to: eluxadoline and sofosbuvir / velpatasvir / voxilaprevir

MONITOR: Coadministration with inhibitors of organic anion transporting polypeptides (OATP) 1B1 and/or 1B3 may increase the plasma concentrations of voxilaprevir, which is a substrate of the hepatic uptake transporters. When a single 100 mg dose of voxilaprevir was administered with a single 600 mg dose of the potent OATP 1B1/1B3 inhibitor cyclosporine (n=24), mean voxilaprevir peak plasma concentration (Cmax) and systemic exposure (AUC) increased by approximately 19.0- and 9.4-fold, respectively. Inhibition of P-glycoprotein (P-gp)- and breast cancer resistance protein (BCRP)-mediated intestinal transport and CYP450 3A4-mediated metabolism of voxilaprevir may also contribute to the overall interaction with cyclosporine. The safety of such high levels of voxilaprevir has not been established.

MANAGEMENT: Caution and monitoring are advised when voxilaprevir is used with OATP 1B1 or 1B3 inhibitors.

velpatasvir voxilaprevir

Applies to: sofosbuvir / velpatasvir / voxilaprevir and sofosbuvir / velpatasvir / voxilaprevir

MONITOR: Coadministration with inhibitors of organic anion transporting polypeptides (OATP) 1B1 and/or 1B3 may increase the plasma concentrations of voxilaprevir, which is a substrate of the hepatic uptake transporters.

Drug and food interactions

Major

eluxadoline food

Applies to: eluxadoline

CONTRAINDICATED: Consumption of more than 3 alcoholic beverages per day may increase the risk of acute pancreatitis during treatment with eluxadoline. Pancreatitis has been reported rarely during clinical trials of eluxadoline, and may or may not be related to sphincter of Oddi spasm.

ADJUST DOSING INTERVAL: High-fat meals may reduce the oral bioavailability of eluxadoline. In 28 healthy volunteers, administration of a single 100 mg dose of eluxadoline with a high-fat meal (approximately 800 to 1000 total calories, 50% from fat) decreased eluxadoline peak plasma concentration (Cmax) and systemic exposure (AUC) by 50% and 60%, respectively, compared to administration in the fasted state. There was no significant effect on the time to peak concentration (Tmax). The clinical relevance of this interaction is unknown. It should be noted that phase 3 clinical trials were conducted under fed conditions.

MANAGEMENT: Chronic or acute excessive use of alcohol should be avoided during treatment with eluxadoline. Alcoholism, alcohol abuse, alcohol addiction, and consumption of more than 3 alcoholic beverages per day are considered contraindications to the use of eluxadoline. The product labeling recommends taking eluxadoline with food. Patients should be advised to stop taking eluxadoline and seek medical attention if they experience potential symptoms of pancreatitis such as persistent nausea, vomiting, abdominal tenderness, and upper abdominal pain, especially that which is made worse after eating or radiates to the back or shoulders.

voxilaprevir food

Applies to: sofosbuvir / velpatasvir / voxilaprevir

ADJUST DOSING INTERVAL: Administration with food enhances the oral bioavailability of sofosbuvir, velpatasvir, and voxilaprevir. Relative to fasting conditions, mean sofosbuvir systemic exposure (AUC) increased by 64% to 144%, mean velpatasvir AUC increased by 40% to 166%, and mean voxilaprevir AUC increased by 112% to 435% when the combined sofosbuvir/velpatasvir/voxilaprevir formulation is administered with food.

MANAGEMENT: Sofosbuvir/velpatasvir/voxilaprevir 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.
