-receptor antagonist for
topical administration to the eyes. Azelastine hydrochloride is a
white crystalline powder
with a molecular weight of 418.37. Azelastine hydrochloride is
sparingly soluble in water,
methanol and propylene glycol, and slightly soluble in ethanol,
octanol, and glycerine.
Azelastine hydrochloride is a racemic mixture with a melting point of
225°C. The

Each mL of azelastine hydrochloride ophthalmic solution contains:
ACTIVE: 0.5 mg
azelastine hydrochloride, equivalent to 0.457 mg of azelastine base;
PRESERVATIVE:
0.125 mg benzalkonium chloride; INACTIVES: disodium edetate dihydrate,

CLINICAL PHARMACOLOGY
Azelastine hydrochloride is a relatively selective histamine H
antagonist and an inhibitor
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.
PHARMACOKINETICS AND METABOLISM
Absorption of azelastine following ocular administration was
relatively low. A study in
symptomatic patients receiving one drop of azelastine hydrochloride
