| Bioactivity | Hydroxyzine, a benzodiazepine antihistamine agent, acts as an orally active histamine H1-receptor and serotonin antagonist. Hydroxyzine has anxiolytic effect and can be used for the research of generalised anxiety disorder[1]. |
| Invitro | Hydroxyzine dihydrochloride inhibits carbachol (10 μM)-induced serotonin release by 34% at 10 μM, by 25% 1 μM and by 17% 0.1 μM in pretreated bladder slices for 60 min[1]. |
| In Vivo | Hydroxyzine dihydrochloride (12.5 mg/kg, 25 mg/kg and 50 mg/kg i.p.) shows little direct analgesic activity but markedly potentiates only the effect of morphine on the vocalization after-discharge which represents the affective component of pain in rats. Hydroxyzine dihydrochloride (50 mg/kg i.p.) potentiates morphine on the tail-flick test, while Hydroxyzine (12.5 mg/kg i.p.) decreases morphine antinociception in rats[3]. |
