Bronchopulmonary effects of elliptinium in anesthetized dogs.
The bronchoconstrictor effect of elliptinium already demonstrated in the guinea-pig is shown in the dog. It is less intense and its onset is prompter. Successive administration of identical doses of elliptinium attenuates the bronchospasm induced, suggesting tachyphylaxis. The previously described indirect bronchoconstrictor effect involving endogenous mediators seems also to be active in these circumstances.
