Drug Name Accutane

PROPECIA significantly reduces DHT, a key cause of hair loss, by inhibiting the formation of DHT in your scalp. Lowering DHT appears to inhibit the further shrinking of affected hair follicles.
After ingestion, it is converted to its active form. The active form of hydroxyzine is a drug called cetirizine (Zyrtec). Although, both hydroxyzine and cetirizine act as antihistamines, hydroxyzine causes more sedation than cetirizine. The FDA approved hydroxyzine in 1956.

 

Antihistamines, like histamine, binds to the histamine receptors, but when they bind to the receptors they do not stimulate the cells to release chemical messengers. In addition, they prevent histamine from binding and stimulating the cells. Hydroxyzine itself has no activity.
Elderly people with psychosis related to dementia (for example, an inability to perform daily activities as a result of increased memory loss), treated with antipsychotic medicines including ABILIFY, are at an increased risk of death compared to placebo. ABILIFY is not approved for the treatment of people with dementia-related psychosis.
