  • Title: Sauvagine: inhibition of gastric acid secretion in rats.
    Author: Improta G, Broccardo M.
    Journal: Peptides; 1991; 12(3):555-7. PubMed ID: 1923934.
    Abstract:
    Sauvagine (SV) powerfully inhibits gastric acid secretion by both the central and peripheral mechanisms. We examined whether adrenergic mechanisms or prostaglandin pathways might mediate the inhibitory action of SV on acid production in pylorus-ligated rats. Adrenalectomy altered the extent of the SV suppressive effect, suggesting that adrenal-derived substances participate in the action of the peptide. Blockade of adrenergic receptors by propranolol did not modify the antisecretory effect of SV, while the alpha-adrenergic antagonist, phentolamine, and the dopaminergic antagonist, haloperidol, potentiated the gastric response to the peptide. The action of SV appeared to be independent of prostaglandin pathways. We conclude that the antiacid effect of SV may be mediated by the adrenal but probably not by adrenergic or prostaglandin mechanisms.
