Pharmacology

Mechanism of Action

Tetrahydrozoline: Ophthalmic decongestant; reduces redness; stimulates alpha-adrenergic receptors in the arterioles of the conjunctiva; produces vasoconstriction; may produce mydriasis when applied to the conjunctiva, but this effect is usually minimal with the concentrations used as ocular decongestants

Zinc sulfate: Provides astringent effects to dry mucus and relieve irritation

Hypromellose: Demulcent that lubricates eye surface
