Cirazoline is a full agonist at the α1A adrenergic receptor, a partial agonist at both the α1B and α1D adrenergic receptors,[1] and a nonselective antagonist to the α2 adrenergic receptor.[2] It is believed that this combination of properties could make cirazoline an effective vasoconstricting agent.[2]

Cirazoline has also been shown to decrease food intake in rats, purportedly through activation of α1 adrenoceptors in the paraventricular nucleus in the hypothalamus of the brain.[3]
