    BackgroundNausea and vomiting are among the most feared side effects of chemotherapy and can prevent cancer patients from completing their treatment regimens. Rolapitant is a highly selective neurokinin-1 (NK-1) receptor antagonist with very good oral activity, central nervous system penetration and a long (180-hour) plasma half-life. Unlike other available NK-1 receptor antagonists, rolapitant does not inhibit or induce cytochrome P450 (CYP) 3A4.MethodsFindings from recent phase II and III clinical trials of rolapitant in patients receiving highly or moderately emetogenic chemotherapy are reviewed and discussed.ResultsThe addition of a single-dose of rolapitant to combination 5-hydroxytryptamine type 3 receptor antagonist and dexamethasone regimens provided increased protection against chemotherapyinduced nausea and vomiting, a benefit that encompassed the entire at-risk period investigated (0-120 hours after initiation of chemotherapy) in patients receiving highly or moderately emetogenic chemotherapy. Rolapitant was well tolerated by patients in these trials, with the overall frequency of treatment- related adverse events similar in patients receiving rolapitant (7.0%) and active placebo (6.3%).ConclusionRolapitant's favorable toxicity profile and lack of CYP3A4-related drug-drug interactions indicate that it would be a suitable treatment for older patients or those with multiple comorbidities, who are likely to be receiving a number of concomitant medications. Future studies should focus on the role of rolapitant in the control of chemotherapy-induced nausea and vomiting in patients receiving multiple-day chemotherapy, specific chemotherapy agents or high-dose chemotherapy and stem cell support.Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.
