Image from Drug Label Content

Chemical Name:

2-(1-naphthylmethyl)-2-imidazoline monohydrochloride

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.

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

VASOCON REGULAR is indicated for use as a topical ocular vasoconstrictor.

CONTRAINDICATIONS

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.

WARNINGS

PRECAUTIONS

General

Use with caution in the presence of hypertension, cardiovascular abnormalities, hyperglycemia (diabetes), hyperthyroidism, ocular infection or injury and when other medications are being used.

Patient Information

Drug Interactions

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).
