Description
Curator's Comment: description was created based on several sources, including: http://www.fda.gov/downloads/AnimalVeterinary/Products/ApprovedAnimalDrugProducts/FOIADrugSummaries/ucm116099.pdf https://www.zoetisus.com/products/dogs/antisedan-_atipamezole_.aspx

Atipamezole is a synthetic α2-adrenergic antagonist. It competitively inhibits α2-adrenergic receptors. Atipamezole is indicated for the reversal of the sedative and analgesic effects of Dexdomitor and Domitor in dogs. Adverse reactions: occasional vomiting may occur. At times, a period of excitement or apprehensiveness may be seen in dogs treated with atipamezole. Other effects of atipamezole include hypersalivation, diarrhea, and tremors.
