NAPHAZOLINE HYDROCHLORIDE OPHTHALMIC SOLUTION USP, 0.1%
On This Page
Naphazoline HCl, an ocular Vasoconstrictor, is an imidazoline derivative sympathomimetic amine. The active ingredient is represented by the structural formula:
VASOCON REGULAR ophthalmic solution is a sterile solution containing 1 mg/mL naphazoline hydrochloride in an isotonic solution containing polyethylene glycol 8000, sodium chloride, polyvinyl alcohol, edetate disodium and purified water; preserved with benzalkonium chloride. Hydrochloric acid and/or sodium hydroxide added to adjust pH. It has a pH of 5.5 to 7.0.
Vasocon - Clinical Pharmacology
Naphazoline constricts the vascular system of the conjunctiva. It is presumed that this effect is due to direct stimulation action of the drug upon the alpha adrenergic receptors in the arterioles of the conjunctiva resulting in decreased conjunctival congestion. Naphalozine belongs to the imidazoline class of sympathomimetics.
Indications and Usage for Vasocon
VASOCON REGULAR is indicated for use as a topical ocular Vasoconstrictor.
Contraindicated in the presence of an anatomically narrow angle or in narrow angle glaucoma or in persons who have shown hypersensitivity to any component of this preparation.
Patients under therapy with MAO inhibitors may experience a severe hypertensive crisis if given a sympathomimetic drug. Use in children, especially infants, may result in CNS depression leading to coma and marked reduction in body temperature.
Use with caution in the presence of hypertension, cardiovascular abnormalities, hyperglycemia (diabetes), hyperthyroidism, ocular infection or injury and when other medications are being used.
Patients should be advised to discontinue the drug and consult a physician if relief is not obtained within 48 hours of therapy, if irritation, blurring, or redness persists or increases, or if symptoms of systemic absorption occur, i.e., dizziness, headache, nausea, decrease in body temperature, or drowsiness.
To prevent contaminating the dropper tip and solution, do not touch the eyelids or the surrounding area with the dropper tip of the bottle. If solution changes color or becomes cloudy, do not use.
Concurrent use of maprotiline or tricyclic antidepressants and naphazoline may potentiate the pressor effect of naphazoline. Patients under therapy with MAO inhibitors may experience a severe hypertensive crisis if given a sympathomimetic drug. (See WARNINGS).
