[Cyproheptadine as an inhibitor of the effects of bradykinin].

A study was made of the influence of ciproheptadin, serotonin and histamine inhibitor, on the effects of exo- and endogenous bradykinin. Ciproheptadin inhibited the effect of bradykinin on a section of a guinea pig intestine in vitro, eliminated the hypotensive effect of bradykinin in rats in vivo, and also blocked the constriction of the vessels of the ear in rabbit and a fall of the blood kininogen level caused by the administration of pyrogenal.
