Preparation, Dosing, and Administration

Single IV Push

APONVIE is administered as a single, 30-second intravenous injection prior to induction of anesthesia.1

Therapeutic plasma concentrations associated with ≥97% receptor occupancy in the brain are achieved within 5 minutes for APONVIE.1-3

Plasma concentrations of aprepitant with APONVIE were higher than those of the oral formulation for approximately 3 hours. By the 4-hour timepoint, the plasma concentrations for the 2 formulations converged and remained similar.4

IV administration allows the drug to enter directly into systemic circulation without the delay associated with absorption processes. This results in 100% bioavailability, making it the best way to deliver a drug rapidly and accurately, and bypassing first-pass metabolism.5

Important Safety Information!


APONVIE is contraindicated in patients with a history of hypersensitivity to aprepitant or any component of the product, and in patients taking pimozide. Increased pimozide levels may cause serious or life-threatening reactions, such as QT prolongation.

Warnings and Precautions

Hypersensitivity Reactions: Serious hypersensitivity reactions, including anaphylaxis, during or soon after administration of aprepitant have occurred. Symptoms including dyspnea, eye swelling, flushing, pruritus, and wheezing have been reported. Monitor patients during and after administration. If hypersensitivity reactions occur, administer appropriate medical therapy. Do not administer APONVIE in patients who experienced these symptoms with previous use of aprepitant.

Clinically Significant CYP3A4 Drug Interactions: Aprepitant is a substrate, weak-to-moderate (dose-dependent) inhibitor, and an inducer of CYP3A4. Use of pimozide, a CYP3A4 substrate, with APONVIE is contraindicated. Use of APONVIE with strong CYP3A4 inhibitors (eg, ketoconazole) may increase plasma concentrations of aprepitant and result in an increased risk of adverse reactions related to APONVIE. Use of APONVIE with strong CYP3A4 inducers (eg, rifampin) may result in a reduction in aprepitant plasma concentrations and decreased efficacy of APONVIE.

Decrease in INR with Concomitant Warfarin: Use of aprepitant with warfarin, a CYP2C9 substrate, may result in a clinically significant decrease in the International Normalized Ratio (INR) of prothrombin time. Monitor the INR in patients on chronic warfarin therapy in the 2-week period particularly at 7 to 10 days, following administration of APONVIE.

Risk of Reduced Efficacy of Hormonal Contraceptives: The efficacy of hormonal contraceptives may be reduced for 28 days following administration of APONVIE. Advise patients to use effective alternative or back-up methods of non-hormonal contraception for 1 month following administration of APONVIE.

Use in Specific Populations

Avoid use of APONVIE in pregnant women as alcohol is an inactive ingredient in APONVIE. There is no safe level of alcohol exposure in pregnancy.

Adverse Reactions

Most common adverse reactions (incidence ≥3%) for APONVIE are constipation, fatigue, and headache and for oral aprepitant are constipation and hypotension.

APONVIE is a substance P/neurokinin-1 (NK1) receptor antagonist, indicated for the prevention of postoperative nausea and vomiting (PONV) in adults.

Limitations of Use: APONVIE has not been studied for treatment of established nausea and vomiting.
