CLINICAL PHARMACOLOGY
Granisetron is a selective 5-hydroxytryptamine (5-HT ) receptor
antagonist with little or
no affinity for other serotonin receptors, including 5-HT ; 5-HT
; 5-HT
; 5-HT ; for
α , α , or β-adrenoreceptors; for dopamine-D ; or for histamine-H ;
benzodiazepine;
picrotoxin or opioid receptors.
Serotonin receptors of the 5-HT type are located peripherally on vagal
nerve terminals
and centrally in the chemoreceptor trigger zone of the area postrema.
During
chemotherapy that induces vomiting, mucosal enterochromaffin cells
release serotonin,
which stimulates 5-HT receptors. This evokes vagal afferent discharge,
inducing
vomiting. Animal studies demonstrate that, in binding to 5-HT
receptors, granisetron
blocks serotonin stimulation and subsequent vomiting after emetogenic
stimuli such as
cisplatin. In the ferret animal model, a single granisetron injection
prevented vomiting
due to high-dose cisplatin or arrested vomiting within 5 to 30
seconds.
In most human studies, granisetron has had little effect on blood
