Cisplatin-like chemotherapeutics cause vomiting via calcium (Ca(2+))-dependent release of multiple neurotransmitters (dopamine, serotonin, substance P, etc.) from the gastrointestinal enterochromaffin cells and/or the brainstem. Intracellular Ca(2+) signaling is triggered by activation of diverse emetic receptors (including tachykininergic NK1, serotonergic 5-HT3, dopaminergic D2, cholinergic M1, or histaminergic H1), whose activation in vomit-competent species can evoke emesis. Other emetogens such as cisplatin, rotavirus NSP4 protein and bacterial toxins can also induce intracellular Ca(2+) elevation...

An oral fixed combination of netupitant/palonosetron (NEPA; Akynzeo(®)) is available for use in the prevention of acute and delayed chemotherapy-induced nausea and vomiting (CINV). Netupitant is a highly selective neurokinin-1 receptor antagonist and palonosetron is a serotonin 5-HT3 receptor antagonist with a distinct pharmacological profile. Complete response rates during the delayed, acute and overall phases were significantly higher with single-dose netupitant 300 mg plus palonosetron 0.5 mg than with single-dose palonosetron 0...

Chemotherapy-induced nausea and vomiting (CINV) is associated with a significant deterioration in quality of life. The emetogenicity of the chemotherapeutic agents, repeated chemotherapy cycles, and patient risk factors significantly influence CINV. The use of a combination of a 5-hydroxytryptamine-3 (5-HT3) receptor antagonists, dexamethasone, and a neurokinin-1 (NK-1) receptor antagonist has significantly improved the control of acute and delayed emesis in single-day chemotherapy. Palonosetron, a second generation 5-HT3 receptor antagonist with a different half-life, different binding capacity, and a different mechanism of action than the first generation 5-HT3 receptor antagonists, appears to be the most effective agent in its class...

Ledipasvir/sofosbuvir (Harvoni) for hepatitis C virus genotype 1 infection; dulaglutide (Trulicity) for glycemic control in type-2 diabetes; netupitant/palonosetron (Akynzeo) for prevention of nausea and vomiting related to chemotherapy; and naloxegol (Movantik) for opioid-induced constipation in patients with chronic noncancer pain.
