Pharmacokinetics
Atarax is highly absorbed from the digestive tract. Bioavailability for ingestion and intramuscular injection is 80%. Hydroxysin is more concentrated in tissues (in particular, in the skin) than in plasma.

Hydroxysin is metabolized in the liver. The main metabolite (45%) is cetirizine, which is a blocker of histamine H1 receptors. Only 0.8% of the hydroxyzine is excreted unchanged in the urine.
