Benoxil

Benoxil - General Information

Benoxil is the name of a local anesthetic, which is used especially in ophthalmology and otolaryngology. Benoxil binds to sodium channels and reversibly stabilizes the neuronal membrane which decreases its permeability to sodium ions.

 

Pharmacology of Benoxil

Benoxil is a local anaesthetic. It may be less irritating than tetracaine, and the onset and duration of action are similar to tetracaine.

 

Benoxil for patients

 

WARNINGS

NOT FOR INJECTION FOR TOPICAL OPHTHALMIC USE ONLY.

Prolonged use of a topical ocular anesthetic is not recommended. It may produce permanent corneal opacification with accompanying visual loss.

 

PRECAUTIONS

Fluress® (Fluorescein Sodium and Benoxinate Hydrochloride Ophthalmic Solution USP) should be used cautiously and sparingly in patients with known allergies, cardiac disease, or hyperthyroidism. The long-term toxicity is unknown; prolonged use may possibly delay wound healing. Although exceedingly rare with ophthalmic application of local anesthetics, systemic toxicity (manifested by central nervous system stimulation followed by depression) may occur.

Protection of the eye from irritating chemicals, foreign bodies and rubbing during the period of anesthesia is very important. Tonometers soaked in sterilizing or detergent solutions should be thoroughly rinsed with sterile distilled water prior to use. Patients should be advised to avoid touching the eye until the anesthesia has worn off.

Pregnancy:

Pregnancy Category C.   Animal reproduction studies have not been conducted with Fluress®. It is also not known whether Fluress® can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Fluress® should be given to a pregnant woman only if clearly needed.

Nursing Mothers:

Caution should be exercised when Fluress® is administered to a nursing woman.

Additional information about Benoxil

Benoxil Indication: Used to temporarily numb the front surface of the eye so that the eye pressure can be measured or a foreign body removed.
Mechanism Of Action: Benoxil binds to sodium channel and reversibly stabilizes the neuronal membrane which decreases its permeability to sodium ions. Depolarization of the neuronal membrane is inhibited thereby blocking the initiation and conduction of nerve impulses.
