MONITOR CLOSELY: Oliceridine can cause prolongation of the QT interval. Theoretically, coadministration with other agents that can prolong the QT interval may result in additive effects and increased risk of ventricular arrhythmias including torsade de pointes and sudden death. In a single-dose thorough QT study involving healthy subjects, dose-dependent QTc prolongation occurred after peak oliceridine plasma concentration at a therapeutic dose of 3 mg (7 msec [upper 90% confidence interval: 9 msec]) and a supratherapeutic dose of 6 mg (12 msec [upper 90% confidence interval: 14 msec]). In a multi-dose thorough QT study of healthy subjects who received intermittent oliceridine dosing over 24 hours to the maximum daily cumulative dose of 27 mg, the maximum mean increase in QTc was 11.7 msec (two-sided upper 90% confidence interval: 14.7 msec) at 9 hours. Despite continued dosing, QTc did not progressively increase and began to decrease after 12 hours. Daily cumulative doses greater than 27 mg have not been examined in a thorough QT study but may increase the risk for QT prolongation. In general, the risk of an individual agent or a combination of agents causing ventricular arrhythmia in association with QT prolongation is largely unpredictable but may be increased by certain underlying risk factors such as congenital long QT syndrome, cardiac disease, and electrolyte disturbances (e.g., hypokalemia, hypomagnesemia, hypocalcemia). Moreover, the extent of drug-induced QT prolongation is dependent on the particular drug(s) involved and dosage(s) of the drug(s).

MANAGEMENT: Caution is recommended if oliceridine is used in combination with other drugs that can prolong the QT interval. The daily cumulative dose of oliceridine should not exceed 27 mg. Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.

Drug and food interactions

Applies to: oliceridine

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Alcohol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics including oliceridine. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

GENERALLY AVOID: Grapefruit or grapefruit juice may increase the plasma concentrations of oliceridine by inhibiting the CYP450 3A4-mediated metabolism of oliceridine, although the interaction has not been studied. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict.

MANAGEMENT: Patients should not consume alcoholic beverages or use drug products that contain alcohol during treatment with oliceridine. Any history of alcohol or illicit drug use should be considered when prescribing oliceridine, and therapy initiated at a lower dosage if necessary. Patients should be closely monitored for signs and symptoms of sedation, respiratory depression, and hypotension. Due to a high degree of interpatient variability with respect to grapefruit juice interactions, patients treated with oliceridine should preferably avoid the consumption of grapefruit and grapefruit juice.

methadone food

Applies to: methadone

Grapefruit juice can increase the blood levels and effects of methadone. If you regularly consume grapefruits or grapefruit juice, you should be monitored for side effects and/or changes in methadone levels. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor. Orange juice is not expected to interact.

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.
