Animal Models of Neurological Disorders: Emesis

Since 2002, 72% of all NDI studies have come from repeat clients.
NeuroDetective International: Pre-clinical Contract Research - Emesis

Emesis model
 


Ferrets are the animal model of choice for evaluating a compound’s anti-emetic properties, because of that animal’s similarities to humans in its neuroanatomy of the brain stem and stomach, and because of the ferret’s sensitivity to emesis-inducing agents. In this model an emesis-inducing agent such as the chemotherapeutic cisplatin, is administered under anesthesia. Following awakening, the numbers of episodes of retching and vomiting are counted. A test compound may be administered prior to, concurrent with, or immediately after the emesis-inducing agent.

Examples of the specific protocols used for NDI studies are described in the following references:
