macimorelin oliceridine

Applies to: macimorelin and oliceridine

GENERALLY AVOID: Macimorelin 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 dedicated thorough QT study consisting of 60 healthy subjects, a mean baseline- and placebo-adjusted change in QTcF of 9.6 msec was observed 4 hours following administration of a supratherapeutic dose of macimorelin 2 mg/kg (4 times the recommended dose), which occurred after the mean maximum macimorelin plasma concentration (0.5 hour). A similar increase in the QTcF interval was also observed in a single-ascending dose study, which included three dose levels: 0.5 mg/kg; 1 mg/kg (2 times the recommended dose); and 2 mg/kg (4 times the recommended dose). All three doses levels produced a similar magnitude of QTcF prolongation as reported in the thorough QT study, suggesting an absence of dose-dependent changes. The mechanism for the observed QTcF prolongation is unknown. 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). In addition, the extent of drug-induced QT prolongation is dependent on the particular drug(s) involved and dosage(s) of the drug(s).

MANAGEMENT: Coadministration of macimorelin with other drugs that can prolong the QT interval should generally be avoided. A sufficient washout period following discontinuation of these drugs is recommended prior to macimorelin administration. Patients treated with any medication that can cause QT prolongation 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

Major

oliceridine food

Applies to: oliceridine

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.

macimorelin food

Applies to: macimorelin

ADJUST DOSING INTERVAL: Food reduces the oral bioavailability of macimorelin. According to the product labeling, administration with a liquid meal decreased macimorelin peak plasma concentration (Cmax) and systemic exposure (AUC) by 55% and 49%, respectively, compared to administration under fasting conditions (i.e., for at least 8 hours).

MANAGEMENT: Macimorelin should be administered after fasting for at least 8 hours.

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.
