Interactions between your drugs

Moderate

acetaminophen taurursodiol

Applies to: Chem Mart Chemadol Children 1 to 5 Years (acetaminophen) and Relyvrio (sodium phenylbutyrate / taurursodiol)

MONITOR: Coadministration with phenylbutyrate/taurursodiol (ursodoxicoltaurine) may increase the plasma concentrations of drugs that are substrates of CYP450 2C19, 2C8, 2C9, 2D6, P-glycoprotein (P-gp), breast cancer resistance protein (BCRP), and/or organic anion transporter 1 (OAT1). Clinical and pharmacokinetic data are currently lacking.

MANAGEMENT: Caution is advised if phenylbutyrate/taurursodiol is used concomitantly with substrates of CYP450 2C19, 2C8, 2C9, 2D6, P-gp, BCRP, and/or OAT1, particularly sensitive substrates or those with a narrow therapeutic range. The prescribing information for taurursodiol combined with sodium phenylbutyrate recommends avoiding coadministration with substrates of these isoenzymes and transporters for which minimal concentration changes may lead to therapeutic failure or serious toxicities. If coadministration is required, dosage adjustments as well as clinical and laboratory monitoring may be appropriate whenever phenylbutyrate/taurursodiol is added to or withdrawn from therapy. The prescribing information for concomitant medications should be consulted to assess the benefits versus risks of coadministration and for any dosage adjustments that may be required.

Drug and food interactions

Major

acetaminophen food

Applies to: Chem Mart Chemadol Children 1 to 5 Years (acetaminophen)

GENERALLY AVOID: Chronic, excessive consumption of alcohol may increase the risk of acetaminophen-induced hepatotoxicity, which has included rare cases of fatal hepatitis and frank hepatic failure requiring liver transplantation. The proposed mechanism is induction of hepatic microsomal enzymes during chronic alcohol use, which may result in accelerated metabolism of acetaminophen and increased production of potentially hepatotoxic metabolites.

MANAGEMENT: In general, chronic alcoholics should avoid regular or excessive use of acetaminophen. Alternative analgesic/antipyretic therapy may be appropriate in patients who consume three or more alcoholic drinks per day. However, if acetaminophen is used, these patients should be cautioned not to exceed the recommended dosage (maximum 4 g/day in adults and children 12 years of age or older).

Moderate

sodium phenylbutyrate food

Applies to: Relyvrio (sodium phenylbutyrate / taurursodiol)

ADJUST DOSING INTERVAL: Coadministration with a high-fat meal may reduce the rate and extent of absorption of sodium phenylbutyrate. When a single 3 g-1 g dose of sodium phenylbutyrate-taurursodiol (sodium phenylbutyrate-ursodoxicoltaurine) was administered to healthy volunteers in the presence of a high-fat, high-calorie meal (approximately 800 to 1000 calories; 500 to 600 calories from fat, 250 calories from carbohydrate, 150 calories from protein), sodium phenylbutyrate peak plasma concentration (Cmax) decreased by 75% and systemic exposure (AUC) decreased by 55%. The Cmax for taurursodiol was not significantly affected, but AUC was increased by 46%. The clinical significance of these changes has not been established. In premarketing studies, patients were advised to take the drug before a meal.

MANAGEMENT: The prescribing information recommends administration of sodium phenylbutyrate-taurursodiol before a meal or snack, particularly in patients of low body weight (less than 70 kg).

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.
