  • The Vomiting Center and the Chemoreceptor Trigger Zone
    Pharmacologic Control of Vomiting Todd R. Tams, DVM, Dipl. ACVIM VCA West Los Angeles Animal Hospital Pharmacologic Control of Acute Vomiting Initial nonspecific management of vomiting includes NPO (in minor cases a 6-12 hour period of nothing per os may be all that is required), fluid support, and antiemetics. Initial feeding includes small portions of a low fat, single source protein diet starting 6-12 hours after vomiting has ceased. Drugs used to control vomiting will be discussed here. The most effective antiemetics are those that act at both the vomiting center and the chemoreceptor trigger zone. Vomiting is a protective reflex and when it occurs only occasionally treatment is not generally required. However, patients that continue to vomit should be given antiemetics to help reduce fluid loss, pain and discomfort. For many years I strongly favored chlorpromazine (Thorazine), a phenothiazine drug, as the first choice for pharmacologic control of vomiting in most cases. The HT-3 receptor antagonists ondansetron (Zofran) and dolasetron (Anzemet) have also been highly effective antiemetic drugs for a variety of causes of vomiting. Metoclopramide (Reglan) is a reasonably good central antiemetic drug for dogs but not for cats. Maropitant (Cerenia) is a superior broad spectrum antiemetic drug and is now recognized as an excellent first choice for control of vomiting in dogs. Studies and clinical experience have now also shown maropitant to be an effective and safe antiemetic drug for cats. While it is labeled only for dogs, clinical experience has shown it is safe to use the drug in cats as well. Maropitant is also the first choice for prevention of motion sickness vomiting in both dogs and cats.

  • A Narrative Review of Tropisetron and Palonosetron for the Control of Chemotherapy-Induced Nausea and Vomiting

Correspondence to: Li Zhang. Medical Oncology Department, Sun Yat-sen University Cancer Center, 651 Dongfeng East Road, Guangzhou 510060, China. Email: [email protected]. Abstract: Review the clinical evidence of tropisetron or palonosetron, an old- and new-generation serotonin (5-hydroxytryptamine) type 3 (5-HT3) receptor antagonist (RA), respectively, for the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients with cancer, and evaluate any difference in efficacy trends. A literature search of the EMBASE and PubMed databases was performed to identify publications of intravenous (IV) tropisetron (generic forms or Navoban®) for the treatment of CINV in patients with various cancers. Data from the pivotal clinical studies evaluating the IV formulation of Aloxi® (palonosetron HCl) were also considered. The effectiveness and safety of each antiemetic was summarized. Sixteen papers for tropisetron fulfilled the inclusion criteria and were extracted for full analysis; publications from six pivotal palonosetron clinical trials were considered. No direct data comparisons could be made between the two drugs, due to the varying definitions of efficacy endpoints between studies. For tropisetron, the rates of no emesis were lower in patients receiving highly emetogenic chemotherapy (HEC) versus moderately emetogenic chemotherapy (MEC).

  • Dolasetron Mesylate)
    Rx only ANZEMET ® Tablets (dolasetron mesylate) DESCRIPTION ANZEMET (dolasetron mesylate) is an antinauseant and antiemetic agent. Chemically, dolasetron mesylate is (2α,6α,8α,9aß)-octahydro-3-oxo-2,6-methano-2H-quinolizin-8-yl-1H­ indole-3-carboxylate monomethanesulfonate, monohydrate. It is a highly specific and selective serotonin subtype 3 (5-HT3) receptor antagonist both in vitro and in vivo. Dolasetron mesylate has the following structural formula: The empirical formula is C19H20N2O3 • CH3SO3H • H2O, with a molecular weight of 438.50. Approximately 74% of dolasetron mesylate monohydrate is dolasetron base. Dolasetron mesylate monohydrate is a white to off-white powder that is freely soluble in water and propylene glycol, slightly soluble in ethanol, and slightly soluble in normal saline. Each ANZEMET Tablet for oral administration contains dolasetron mesylate (as the monohydrate) and also contains the inactive ingredients: carnauba wax, croscarmellose sodium, hypromellose, lactose, magnesium stearate, polyethylene glycol, polysorbate 80, pregelatinized starch, synthetic red iron oxide, titanium dioxide, and white wax. The tablets are printed with black ink, which contains lecithin, pharmaceutical glaze, propylene glycol, and synthetic black iron oxide. CLINICAL PHARMACOLOGY Dolasetron mesylate and its active metabolite, hydrodolasetron (MDL 74,156), are selective serotonin 5-HT3 receptor antagonists not shown to have activity at other known serotonin receptors and with low affinity for dopamine receptors. The serotonin 5-HT3 receptors are located on the nerve terminals of the vagus in the periphery and centrally in the chemoreceptor trigger zone of the area postrema. It is thought that chemotherapeutic agents produce nausea and vomiting by releasing serotonin from the enterochromaffin cells of the small intestine, and that the released serotonin then activates 5-HT3 receptors located on vagal efferents to initiate the vomiting reflex.
