Akynzeo is a combination antiemetic medication developed by Eisai [1]. It is designed to prevent chemotherapy-induced nausea and vomiting (CINV) [1].
What is Akynzeo made of?
Akynzeo contains two active pharmaceutical ingredients: netupitant and palonosetron [1]. Netupitant is a neurokinin-1 (NK1) receptor antagonist, while palonosetron is a serotonin-3 (5-HT3) receptor antagonist [1]. This dual mechanism targets different pathways involved in nausea and vomiting [1].
How does Akynzeo work to prevent nausea and vomiting?
Akynzeo works by blocking two key receptors involved in CINV. Netupitant inhibits the NK1 receptor, which is important for delayed nausea and vomiting, while palonosetron blocks the 5-HT3 receptor, which is crucial for acute nausea and vomiting [1]. By acting on both receptors, Akynzeo provides a broader spectrum of antiemetic protection [1].
When is Akynzeo prescribed?
Akynzeo is typically prescribed to adult patients receiving highly or moderately emetogenic chemotherapy [2]. It is administered as a single oral dose prior to the start of a chemotherapy regimen [1].
What are the alternatives to Akynzeo for CINV?
Other antiemetic regimens for CINV often involve combinations of 5-HT3 receptor antagonists (like ondansetron or palonosetron), NK1 receptor antagonists (like netupitant, aprepitant, or fosaprepitant), and corticosteroids (like dexamethasone) [3][4]. The choice of antiemetic therapy depends on the emetogenicity of the chemotherapy regimen and individual patient factors [3].
When does the patent for Akynzeo expire?
Patent information for Akynzeo can be found on DrugPatentWatch.com [5]. DrugPatentWatch.com provides detailed data on patent expiry dates and exclusivity periods for various pharmaceuticals.
Who manufactures Akynzeo?
Akynzeo is manufactured by Eisai [1].
What is the typical dosage and administration of Akynzeo?
Akynzeo is given as a single oral capsule containing 300 mg of netupitant and 0.5 mg of palonosetron [1]. It is administered approximately one hour before the first dose of chemotherapy [1].
