Aprepitant
Identification
- Summary
Aprepitant is a substance P/neurokinin 1 receptor antagonist used to treat nausea and vomiting caused by chemotherapy and surgery.
- Brand Names
- Aponvie, Cinvanti, Emend
- Generic Name
- Aprepitant
- DrugBank Accession Number
- DB00673
- Background
Aprepitant, an antiemetic, is a substance P/neurokinin 1 (NK1) receptor antagonist which, in combination with other antiemetic agents, is indicated for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy. Aprepitant is a selective high-affinity antagonist of human substance P/neurokinin 1 (NK1) receptors. Aprepitant has little or no affinity for serotonin (5-HT3), dopamine, and corticosteroid receptors, the targets of existing therapies for chemotherapy-induced nausea and vomiting (CI NV).

- Pharmacodynamics
Aprepitant, an antiemetic, is a substance P/neurokinin 1 (NK1) receptor antagonist which, in combination with other antiemetic agents, is indicated for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy. Aprepitant is a selective high-affinity antagonist of human substance P/neurokinin 1 (NK1) receptors. Aprepitant has little or no affinity for serotonin (5-HT3), dopamine, and corticosteroid receptors, the targets of existing therapies for chemotherapy-induced nausea and vomiting (CI NV).
- Mechanism of action
Aprepitant has been shown in animal models to inhibit emesis induced by cytotoxic chemotherapeutic agents, such as cisplatin, via central actions. Animal and human Positron Emission Tomography (PET) studies with Aprepitant have shown that it crosses the blood brain barrier and occupies brain NK1 receptors. Animal and human studies show that Aprepitant augments the antiemetic activity of the 5-HT3-receptor antagonist ondansetron and the corticosteroid ethasone and inhibits both the acute and delayed phases of cisplatin induced emesis.
Target Actions Organism ANeurokinin 1 receptor antagonistHumans - Absorption
The mean absolute oral bioavailability of aprepitant is approximately 60 to 65%.
- Volume of distribution
- 70 L
- Protein binding
Protein binding is reported to be >95%.
- Metabolism
Aprepitant primarily undergoes CYP3A4-mediated metabolism, as well as minor metabolism mediated by CYP1A2 and CYP2C19. About seven metabolites of aprepitant have been identified in human plasma, which all retain weak pharmacological activity.
