The 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists have become the cornerstone for preventing and treating chemotherapy-induced nausea and vomiting. Four 5-HT3 antagonists are commercially available in the United States, and numerous reports have been published comparing 2 or more agents. The studies ranged from randomized, double-blinded to open-label or retrospective trials; included chemotherapy-naïve and –non-naïve patients; and covered a range of doses and routes of administration with and without concomitant steroids, for preventing and treating nausea and vomiting after highly and moderately high emetogenic chemotherapy. With few exceptions, the studies uniformly show an equivalent efficacy rate and side effect profile among the various agents at equivalent doses. This article reviews the pharmacology of the class for insight into minor differences among the agents that could possibly influence drug selection for certain patients, and considers data on the absorption, half-life, metabolism, and receptor activity. Clinical trials support the claim of various guidelines that the 5-HT3 receptor antagonists are therapeutically similar in safety and efficacy, particularly because the current best practice for preventing nausea and vomiting after highly and moderately high emetogenic chemotherapy is a combination of a 5-HT3 antagonist, steroids, and aprepitant.

Background Despite the efficacy of prophylaxis with serotonin type 3 (5-HT3) receptor antagonists, nausea and vomiting are still among the most common chemotherapy-induced toxicities. The aim of this study was to evaluate the efficacy of adding aprepitant in patients with chemotherapy-induced nausea and vomiting (CINV) refractory to prophylaxis with 5-HT3 receptor antagonists and dexamethasone. Patients and Methods Between January 2008 and November 2010, 51 patients (median age 59 years) with a variety of malignancies (breast cancer: 23; lung cancer: 12; sarcoma: 6; ovarian cancer: 3; other: 7) were enrolled. All patients were refractory to antiemetic therapy according to ASCO guidelines and developed at least grade 2 nausea and/or vomiting after the first chemotherapy course. Aprepitant was given at 125 mg on day 1 and 80 mg on days 2–3. Patients also received a single dose of palonosetron 250 μg on day 1 plus dexamethasone 12–20 mg at a constant dose. Results After addition of aprepitant, the number of patients with grade 3/4 nausea decreased from 31 (61%) to 4 (8%), and those with grade 2 nausea from 20 (39%) to 6 (12%) [both p

Abstract Context: Currently, there is limited data on the prevention of chemotherapy-induced nausea and vomiting (CINV) in Indian population with aprepitant containing regimens. Aims: The aim was to assess the Efficacy and Safety of Aprepitant for the prevention of nausea and vomiting associated with highly emetogenic chemotherapy/moderately emetogenic chemotherapy (HEC/MEC) regimens. Settings and Design: Investigator initiated, multicentric, open-label, prospective, noncomparative, observational trial. Subjects and Methods: Triple drug regimen with aprepitant, palonosetron, and dexamethasaone administration was assessed for the prevention of CINV during acute, delayed, and the overall phase (OP) for HEC/MEC Regimens. The primary endpoint was complete response (CR; no emesis and no use of rescue medication) and the key secondary endpoint was the complete control (CC; no emesis, no rescue medication and no more than mild nausea) during the OP. Statistical Analysis Used: Perprotocol efficacy was analyzed for the first cycle with results represented in terms of CR/CC rates using descriptive statistics. Results: Seventy-five patients were included in the study with median age of 49.7 years and 89.7% being females. The CR rate (OP) for patients administered HEC or MEC regimens during the first cycle were 92% and 90.9%, respectively. Similarly, the CC rates (OP) were 75% and 90% for these regimens, respectively. 7 (9.2%) patients reported adverse drug reactions that were mild and transient with no reports of any serious adverse events. Conclusions: Use of aprepitant containing regimen for patients receiving HEC/MEC regimen resulted in significantly high CR and CC response rates, which further consolidate its potential role to improve patient quality of life and compliance to disease management.
