Consequently, the American Gastroenterological Association (AGA) recommends the use of antihistamines and anti-cholinergics in the treatment of nausea secondary to vertigo and motion sickness.14Migraine headaches frequently are associated with nausea.Although the mechanism is not well understood, antiemetics are useful in the treatment of nausea, and of the headache itself. Nausea and vomiting are mediated primarily by visceral stimulation through dopamine and serotonin, by vestibular and central nervous system causes through histamine and acetylcholine, and by chemoreceptor trigger zone stimulation through dopamine and serotonin. Antihistamines and anticholinergic agents are most effective in patients with nausea resulting from vestibular and central nervous system causes.

An understanding of the pathophysiology of nausea and the mechanisms of antiemetics can help family physicians improve the cost-effectiveness and efficacy of therapy.Complementary and alternative therapies, such as ginger, acupressure, and vitamin BNausea and vomiting are common complications of multiple conditions, procedures, and therapies, and adversely affect quality of life in millions of patients each year.Pregnancy-induced nausea alone has been estimated to cause 8.5 million lost working days annually.1 Postoperative nausea and vomiting have been shown to increase hospitalization costs by 5 per patient.2 In many instances, therapy for nausea and vomiting is directed at specific, well-studied mechanisms that have been shown to cause nausea.
Because of their diffuse blockade of serotonin, these agents have become the primary treatment for a variety of causes of nausea.
Costs for these agents in the treatment of patients with postoperative nausea range from approximately to 5 per dose.7Antiemetics frequently are used to treat nausea induced by vestibular or central nervous system causes.
Unlike other forms of nausea, which tend to be mediated by dopamine and serotonin, vestibular system–induced nausea is mediated primarily by histamine and acetylcholine .
antagonists are the newest and most expensive antiemetics.
The three primary agents—ondansetron (Zofran), dolasetron (Anzemet), and granisetron (Kytril)—have similar efficacy.
