Description:
Naphazoline hydrochloride is the common name for 2-(1-naphthylmethyl)-2-imidazoline hydrochloride. It is a sympathomimetic agent with marked alpha adrenergic activity. It is a vasoconstrictor with a rapid action in reducing swelling when applied to mucous membrane. It acts on alpha-receptors in the arterioles of the conjunctiva to produce constriction, resulting in decreased congestion. It is an active ingredient in several over-the-counter formulations including Clear Eyes and Naphcon eye drops.

Application:
Naphazoline is a decongestant used to relieve redness, puffiness, and itchy/watering eyes due to colds, allergies, or eye irritations (smog, swimming, or wearing contact lenses). It is known as a sympathomimetic (alpha receptor agonist) that works in the eye to decrease congestion.
Some brands of naphazoline eye drops also contain other ingredients. Lubricants (such as glycerin, hypromellose, or polyethylene glycol 300) help protect the eyes from more irritation. Zinc sulfate, an astringent, helps reduce redness and irritation.
