Duration of ActionThe effect usually lasts for 2 to 6 hours.

How It Works

This medicine works by stimulating alpha-adrenergic receptors on the blood vessels of the conjunctiva. Naphazoline and phenylephrine are sympathomimetic amines that cause vasoconstriction, thereby reducing blood flow to the eye surface and decreasing redness and swelling. The effect is local and temporary.

Mechanism Steps

1
Binding to alpha-adrenergic receptors: Naphazoline and phenylephrine bind to alpha-1 and alpha-2 adrenergic receptors on the smooth muscle of conjunctival blood vessels.
2
Vasoconstriction: Receptor activation triggers intracellular signaling that causes the smooth muscle to contract, narrowing the blood vessels.
3
Reduced blood flow and redness: The narrowed vessels reduce blood flow to the eye surface, which decreases visible redness and swelling.
4
Temporary relief: The effect lasts for a few hours, after which the vessels gradually return to their previous state.
