What class of drug is Hydroxyzine?

Hydroxyzine is classified as an antihistamine, which means it is effective in blocking the action of histamine, a substance in the body that is responsible for allergic reactions. It is primarily used to treat allergy symptoms, anxiety, and itching, as well as for sedation prior to surgeries. By inhibiting histamine activity, it can alleviate symptoms like runny nose, sneezing, and itching that accompany allergic reactions. Additionally, hydroxyzine's ability to cross the blood-brain barrier contributes to its anxiolytic effects, making it a useful option for managing anxiety in some contexts, but its primary classification remains that of an antihistamine.

Understanding the roles of different drug classes is crucial, as they each have unique mechanisms of action and therapeutic uses. For instance, analgesics are used for pain relief, antidepressants target mood disorders, and anxiolytics are primarily focused on reducing anxiety. Recognizing hydroxyzine as an antihistamine helps clarify its appropriate applications in clinical practice.
