Substance P (SP) is a member of the tachykinin family of bioactive peptides and has highest affinity for the NK-1 receptor.

CP-122,721 (0. 1 mg/kg), a potent selective tachykinin NK (1) receptor antagonist, significantly reduced the emetic responses to MTX.
Copper sulfate-induced emesis in dogs was also prevented by FK1052, tropisetron, and CP-122,721 but not by ondansetron.

Pretreatment with the tachykinin NK-1 receptor antagonists HSP-117 (1.0 microg) and CP-99,994 (7.5 microg) into the AP decreased the numbers of vomits and retches induced by morphine and copper sulphate.

In AP ablated animals the selective NK (1) receptor antagonist CP-99, 994 (1 mg kg (-1) i.v.) blocked the emetic response to copper sulphate as it did in intact animals.
