Additional information about AVIL

AVIL Indication: Used to treat allergic conditions such as hay fever or urticaria.
Mechanism Of Action: Antihistamines such as pheniramine appear to compete with histamine for histamine H1- receptor sites on effector cells. The antihistamines antagonize those pharmacological effects of histamine which are mediated through activation of H1- receptor sites and thereby reduce the intensity of allergic reactions and tissue injury response involving histamine release.
