of the release of histamine and other mediators from cells (e.g. mast
cells) involved in
the allergic response. Based on in-vitro studies using human cell
lines, inhibition of other
mediators involved in allergic reactions (e.g. leukotrienes and PAF)
has been
demonstrated with azelastine hydrochloride. Decreased chemotaxis and
activation of
eosinophils has also been demonstrated.
