Hydroxyzine was one of the first blockers of H1-histamine receptors. However, it has a sedative and anxiolytic effect; possesses m-anticholinergic and antiemetic properties.
The chemical structure is close to some modern anti-histamine drugs (see Cetirizine), but as an anti-histamine (anti-allergic) agent, it is currently not widely used, but has become used as a relatively “mild” tranquilizing agent.
When taken orally, it is absorbed quickly, Cmax is 2 hours, T Ѕ - 12-24 hours.
Indications for use are mainly irritability, tension, a sense of fear, alcohol withdrawal syndrome, and sedation. It is also used (in connection with antihistamine activity) for pruritic dermatoses.
There is evidence of the effectiveness of hydroxyzine in cardiac neurotic disorders.
