- DrugBank Accession Number
- DB06711
- Background
Naphazoline is a rapid acting imidazoline sympathomimetic vasoconstrictor of ocular or nasal artierioles6,7. It acts to decrease congestion and is found in many over the counter (OTC) eye drops and nasal preparations6,7.
Naphazoline was first developed in 1942 as a nasal formulation for congestion4.

- Pharmacodynamics
Naphazoline is a sympathomimetic alpha adrenergic agonist that acts to vasoconstrict nasal or ocular arterioles, resulting in reduced congestion at the site of administration6,7.
- Mechanism of action
Naphazoline is a vasoconstrictor that functions by stimulating alpha adrenergic receptors in arterioles leading to decreased congestion at the site of administration6.
Naphazoline causes the release of norepinephrine in sympathetic nerves3. Norepinephrine binds to alpha adrenergic receptors and causes vasoconstriction3. Naphazoline is also a mild beta adrenergic receptor agonist, which can cause rebound vasodilation after the alpha adrenergic stimulation has ended3. Naphazoline's release of norepinephrine also triggers a negative feedback loop which decreases production of norepinephrine, which can lead to rhinitis medicamentosa after long term use when naphazoline is stopped3.
Target Actions Organism AAlpha-2A adrenergic receptor agonistHumans AAlpha-1A adrenergic receptor agonistHumans - Absorption
Absorption data for naphazoline are scarce but imidazoline compounds in general are weakly basic and lipophilic, with high bioavailability from the gastrointestinal tract5.
- Volume of distribution
Distribution data for naphazoline are scarce but imidazoline compounds are distributed throughout the body, and can cross the blood-brain barrier5.
- Protein binding
Protein binding data for naphazoline is unavailable12.
- Metabolism
Metabolism data for naphazoline are scarce. Imidazoline compounds undergo some hepatic metabolism but a large fraction of the dose may be excreted unchanged in the urine5.
- Route of elimination
Imidazoline compounds undergo some hepatic metabolism but a large fraction of the dose may be excreted unchanged in the urine5. Urinary excretion is higher with more acidic urine5.
- Half-life
Half life has not been determined but effects last for 4 to 8 hours7. Other imidazoline compounds have half lives varying from 2 to 12 hours5.
- Clearance
Clearance data for naphazoline is unavailable12.

- Toxicity
In high doses or when ingested, naphazoline can lead to central nervous system depression (which can progress to coma and death), hypothermia, bradycardia, and death1. This effect is especially pronounced in children under 6 years1,2.
Long term use of naphazoline can lead to rhinitis medicamentosa once naphazoline is stopped3. This condition is a result of norepinephrine release by naphazoline triggering a negative feedback loop3.
Safety and effectiveness in children under 12 has not been established12. Studies in elderly patients have yet to be performed12. Risk in pregnancy, breast feeding, and on overall fertility have not been established, though pregnant and breast feeding patients should consider the risk and benefit before starting naphazoline treatment12.
