Type

Description

Cirazoline acts on a number of α adrenergic receptors. It is an agonist of α1A, partial agonist of α1B and α1D, and a nonselective antagonist of α2. It is believed that this combination of properties could make cirazoline an effective vasoconstricting agent. 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.
