How it works

From the US prescribing label for the same active substance (levocetirizine dihydrochloride). It describes the substance, not this exact product.

Levocetirizine, the active enantiomer of cetirizine, is an antihistamine; its principal effects are mediated via selective inhibition of H 1 receptors.

The antihistaminic activity of levocetirizine has been documented in a variety of animal and human models.

The shape is a standard model drawn from the two times above, not a measurement. How fast a medicine acts and wears off also depends on the dose, the form and the person.
How the body breaks it down

The extent of metabolism of levocetirizine in humans is less than 14% of the dose and therefore differences resulting from genetic polymorphism or concomitant intake of hepatic drug metabolizing enzyme inhibitors are expected to be negligible.

How it leaves the body

This finding would also be applicable for levocetirizine, as levocetirizine and cetirizine are both predominantly excreted in urine.

With food

Food had no effect on the extent of exposure (AUC) of the levocetirizine tablet, but T max was delayed by about 1.25 hours and C max was decreased by about 36% after administration with a high fat meal; therefore, levocetirizine can be administered with or without food.
