Both aprepitant and fosaprepitant are associated with a low rate of serum enzyme elevations after treatment which are similar to rates with comparator therapies, and neither agent has been clearly linked to cases of clinically apparent liver injury with jaundice.</p></div><div id="Aprepitant.Background"><h3>Background</h3><p>Aprepitant (a pre&#x02019; pi tant) is a substance P antagonist that blocks the neurokinin 1 (NK1) receptor, which is found in the central nervous system and induces the vomiting reflex when activated by its ligand, substance P. Aprepitant has been shown to inhibit both acute and delayed nausea and vomiting associated with cancer chemotherapy and surgical procedures. It appears to act synergistically with serotonin type 3 (5-HT3) receptor blockers. Aprepitant was approved for use in the United States in 2003 and its prodrug fosaprepitant in 2008. Current indications are for prevention of nausea and vomiting after highly or moderately emetogenic chemotherapy regimens. Aprepitant is available as 40, 80 and 125 mg capsules generically and under the brand name Emend. The typical dose regimen of aprepitant for prevention of nausea and vomiting after cancer chemotherapy is 125 mg given one hour before chemotherapy in combination with a 5-HT3 receptor blocker and dexamethasone (12 mg orally), followed by a lower dose of aprepitant (80 mg) on days 2 and 3 along with a lower dose of dexamethasone (8 mg) orally on days 2, 3 and 4. Dose regimens are slightly different for children, and for moderately emetogenic chemotherapy regimens, and for prevention of postoperative nausea and vomiting. Fosaprepitant, the prodrug of aprepitant, has similar clinical effects, side effects and metabolism, and is available as a lyophilized powder for reconstitution in single use vials of 150 mg generically and under the brand name Emend. It is given as a single intravenous infusion of 150 mg started 30 minutes before chemotherapy in combination with an intravenous 5-HT3 receptors blocker and dexamethasone given orally in a manner similar to aprepitant. Common side effects of aprepitant and fosaprepitant include fatigue, drowsiness, dizziness, headache, diarrhea and abdominal discomfort. Infusion reactions are not uncommon with fosaprepitant but rarely severe, although cases of anaphylaxis and Stevens Johnson syndrome have been described.</p></div><div id="Aprepitant.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>In preregistration clinical trials of aprepitant, serum aminotransferase elevations occurred in 6% of treated patients compared to 4.3% in controls receiving cancer chemotherapy. The aminotransferase elevations were transient, mild-to-moderate in severity, and not associated with symptoms or jaundice. There have been no convincing cases of clinically apparent liver injury attributable to aprepitant or fosaprepitant published in the literature and thus, significant liver injury from their use must be exceedingly rare if it occurs at all.</p><p><a class="def" href="/books/n/livertox/glossary/def-item/glossary.likelihood-score/">Likelihood score</a>: E (unlikely causes of clinically apparent liver injury).</p></div><div id="Aprepitant.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The serum aminotransferase elevations that occur after aprepitant therapy are more likely due to the chemotherapy rather than the antiemetic. The lack of reported cases of liver injury due to aprepitant and fosaprepitant may be due to the low doses and short duration of typical therapy. Aprepitant is metabolized by and inhibits hepatic CYP 3A4 and has the potential to cause significant drug-drug interactions. It also has significant interactions with warfarin and with hormonal contraceptives.</p><p>Drug Class: <a href="/books/n/livertox/GastrointestinalAgen/">Gastrointestinal Agents</a>, <a href="/books/n/livertox/AntiemeticAgents/">Antiemetic Agents</a></p><p>Other Drugs in the Subclass, Substance P/Neurokinin-1 Receptor Antagonists: <a href="/books/n/livertox/Fosnetupitant/">Fosnetupitant</a>, <a href="/books/n/livertox/Rolapitant/">Rolapitant</a></p></div></div><div id="Aprepitant.PRODUCT_INFORMATION"><h2 id="_Aprepitant_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
