Description
Sources: https://www.accessdata.fda.gov/drugsatfda_docs/label/2015/206500s000lbl.pdf | http://www.ema.europa.eu/docs/en_GB/document_library/EPAR_-_Public_assessment_report/human/004196/WC500228744.pdf | https://livertox.nih.gov/Rolapitant.htm

Rolapitant (VARUBI) is neurokinin 1 (NK1) receptor antagonist. Rolapitant does not have significant affinity for the NK2 or NK3 receptors. Drug is indicated in combination with other antiemetic agents in adults for the prevention of delayed nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy, including, but not limited to, highly emetogenic chemotherapy. Most common adverse reactions are: neutropenia and hiccups at Cisplatin Based Highly Emetogenic Chemotherapy; decreased appetite, neutropenia and dizziness at Moderately Emetogenic Chemotherapy and Combinations of Anthracycline and Cyclophosphamide. Inhibition of BCRP and P-gp by rolapitant can increase plasma concentrations of the concomitant drug and potential for adverse reactions. Strong CYP3A4 Inducers (e.g., rifampin) can significantly reduce plasma concentrations of rolapitant and decrease the efficacy of VARUBI.

Concurrent ketoconazole, a strong CYP3A4 inhibitor did not significantly affect systemic exposure to rolapitant.
