Hodoodo CAT#: H318192
CAS#: 29216-28-2
Description: Mequitazine is a potent histamine H1 antagonist or antihistamine. It competes with histamine for the normal H1-receptor sites on effector cells of the gastrointestinal tract, blood vessels and respiratory tract. Mequitazine provides effective, temporary relief of sneezing, watery and itchy eyes, and runny nose due to hay fever and other upper respiratory allergies.
