How it works
From the US prescribing label for the same active substance (CETIRIZINE HYDROCHLORIDE). It describes the substance, not this exact product.
Mechanism of Actions Cetirizine, a human metabolite of hydroxyzine, is an antihistamine; its principal effects are mediated via selective inhibition of peripheral H 1 receptors.
The antihistaminic activity of cetirizine has been clearly documented in a variety of animal and human models.
Cetirizine is metabolized to a limited extent by oxidative O-dealkylation to a metabolite with negligible antihistaminic activity.
Food had no effect on the extent of cetirizine exposure (AUC) but T max was delayed by 1.7 hours and C max was decreased by 23% in the presence of food.
