HIDE SMILES / InChI
Nemazoline (A-57219) is a nasal decongestant. It has alpha 1-agonist/alpha 2-antagonist activity and was more effective and long-acting than oxymetazoline on canine nasal mucosa, in-vitro and in-vivo. Upon intranasal administration to dogs, the compound was devoid of systemic effects up to a concentration 1000 times that needed for local decongestant effect (1.65 micrograms, atomized from a 1 microgram mL-1 solution) suggesting limited mucosal absorption. After nasal administration to rats for 15 days at a concentration 1000 times greater than that required for nasal decongestion, no mucosal tissue toxicity or systemic effects were seen.
