Effect of apomorphine on reflexes of the respiratory airways

Abstract

The effect of apomorphine on the response to trachea and glottis excitation has been studied in dogs. It has been found that apomorphine causes a very significant diminution of coughing, and it decreases the respiratory inhibition that characterizes the response to glottis excitation. The correlations between coughing and vomiting have been analyzed and it has been demonstrated that trachea stimulation during the emetic phase of apomorphine does not influence vomiting in any case.
