  • Title: Cardiovascular effects of putrescine in dogs after systemic, intra-arterial vertebral and intraventricular injection.
    Author: Rossi F, Nisticò G, De Marco G, Berrino L, Matera C, Bile G, Marmo E.
    Journal: Res Commun Chem Pathol Pharmacol; 1984 Oct; 46(1):43-52. PubMed ID: 6505389.
    Abstract:
    Putrescine produced in anesthetized dogs significant cardiovascular changes at higher doses than other transmitters. The hypotensive response observed after intravenous injection is due to histamine release. Tachycardic effects seem to be due both to release of histamine and to a reflex stimulation of carotid-sinus baroreceptors. The hypotensive and bradycardic effects observed after microinjection of putrescine into the III cerebral ventricle or into the vertebral artery are due to an increase in parasympathetic output.
