🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAfter topical application to the eye, phenylephrine and naphazoline can be absorbed systemically through the conjunctival blood vessels and the nasolacrimal duct. The extent of systemic absorption depends on the dose, frequency of use, and whether the lacrimal puncta are occluded. Systemic absorption can lead to cardiovascular and central nervous system effects.
DistributionNot established from the available information.
Protein BindingNot established from the available information.
MetabolismNot established from the available information.
Half-LifeNot established from the available information.
ExcretionNot established from the available information.
BioavailabilityNot established from the available information.
Onset of ActionThe onset of action is typically within minutes after instillation, with noticeable reduction in redness occurring rapidly.
Peak Plasma TimeNot established from the available information.
Duration of ActionThe duration of action is usually 2 to 6 hours, but this can vary between individuals.

How It Works

This medicine works by stimulating alpha-adrenergic receptors on the blood vessels of the eye. Phenylephrine and naphazoline are both sympathomimetic amines that cause constriction of the conjunctival arterioles. This narrowing reduces blood flow to the surface of the eye, which decreases redness and swelling. The effect is local and temporary, lasting for a few hours. Naphazoline is a more potent vasoconstrictor than phenylephrine and also has some effect on alpha-2 receptors, while phenylephrine primarily acts on alpha-1 receptors. Together, they provide rapid but short-lived relief of ocular hyperemia.

Mechanism Steps

1
Instillation and local absorption: The eye drops are placed into the conjunctival sac, where the active ingredients come into contact with the surface of the eye.
2
Alpha-adrenergic receptor stimulation: Phenylephrine and naphazoline bind to and stimulate alpha-1 and alpha-2 adrenergic receptors on the smooth muscle cells of conjunctival blood vessels.
3
Vasoconstriction: Stimulation of these receptors causes the smooth muscle to contract, narrowing the blood vessels and reducing blood flow to the conjunctiva.
4
Reduced redness and swelling: The decreased blood flow leads to a visible reduction in eye redness and a decrease in mild swelling or puffiness.
5
Temporary effect and potential rebound: The vasoconstriction is temporary. With prolonged use, the blood vessels may become less responsive, and when the medicine is stopped, they may dilate excessively, causing rebound redness.
