Pharmacology of Hydroxyzine
Hydroxyzine serves as a first-generation antihistamine and anxiolytic agent. It is commonly used for managing anxiety and has antihistaminic properties. Here, you’ll find detailed information on its mechanism of action, and its pharmacokinetics and metabolism.
Mechanism of Action
Hydroxyzine acts as an H1 receptor antagonist. By blocking these receptors, it helps reduce symptoms of allergic reactions such as itching and swelling. It competes with histamine for receptor sites, preventing histamine from having its usual effect.
Hydroxyzine is also known for its sedative properties. It can cross the blood-brain barrier, leading to CNS depression. That’s why it’s often prescribed for anxiety and insomnia.
Additionally, hydroxyzine is metabolized to cetirizine, another antihistamine. Cetirizine is less sedative and has a longer half-life. This makes it an effective antihistaminic while reducing sedative effects.
Pharmacokinetics and Metabolism
Hydroxyzine is available in two forms: hydrochloride and pamoate. These forms differ slightly in their pharmacokinetics. When taken orally, hydroxyzine is rapidly absorbed from the gastrointestinal tract.
The mean half-life of hydroxyzine is around 20-25 hours. Most of the drug is metabolized in the liver to cetirizine. The mean hydroxyzine clearance rate is about 8.65 mL/min/kg in healthy adults.
In elderly patients, hydroxyzine has a longer half-life. You should always consider age and liver function when determining the dosage. Hydroxyzine elimination is impaired in conditions like primary biliary cirrhosis, so dose adjustments might be necessary.
If you need more details, the pharmacokinetics and pharmacodynamics studies of hydroxyzine in elderly patients provide additional insights.
