Phentolamine and dibenamine action on the carotid reflexes induced by lobeline
1977
: On the carotid reflexogenic zone lobeline provoques : 1) a increase of amplitude and rate of respiratory movements with bradycardia and hypotension ; 2) a secondary decrease of amplitude and rate of breathing with tachycardia. Acting on the reflexogenic zone, phentolamine and dibenamine provoque a transitory weakening or disappearance of these reflexes. These effects are induced by a local action, because they are not observed by intravenous injection of the drugs and the lobeline reflexes starting from the carotid sinus of the other side are not affected.
