Fluorometholone is a corticosteroid with an excellent anti-inflammatory action with no significant influence on the intraocular pressure. The anti-inflammatory activity of Fluorometholone is at least 40 times stronger than that of Hydrocortisone. Corticosteroids are thought to act by the introduction of phospholipase A2 inhibitory proteins. It is postulated that these proteins control the biosynthesis of potent mediators of inflammation such as prostaglandin and leukotrienes by inhibiting the release of their common precursor, arachidonic acid. Arachidonic acid is released from membrane phospholipids by phospholipase A2. In comparison with other corticosteroids Fluorometholone is more rapidly degraded in tissue and therefore has less effect on the intraocular pressure. The immunosuppressive action of Fluorometholone is less pronounced than that of Dexamethasone.

Corticosteroids such as fluorometholone inhibit the inflammatory response to a variety of inciting agents and probably delay or slow healing. They inhibit the edema, fibrin deposition, capillary dilation, leukocyte migration, capillary proliferation, fibroblast proliferation, deposition of collagen, and scar formation associated with inflammation.

Neomycin is a broad-spectrum aminoglycoside antibiotic drug that is derived from the metabolic products of Streptomyces fradiae. Neomycin is a complex comprised of three components, neomycin A, B, and C. Neomycin B, also known as framycetin, is the most active component of the complex and neomycin C is the isomer of neomycin B, making these two stereoisomers the active components of neomycin. Neomycin A, or neamine, is a moiety that conjoins two molecules of neomycin B and C together. Neomycin is active against both gram-positive and gram-negative organisms and mediates its pharmacological action by binding to bacterial ribosomes and inhibiting protein synthesis, which is crucial for the survival of bacteria.

Neomycin sulfate is the most common form for pharmaceutical preparations; because the compound is a complex, the amount of neomycin in products is measured in units. Neomycin sulfate as monotherapy is available in an oral solution for adjunct use in the treatment of hepatic coma. It is also used in combination with polymyxin B sulfates and hydrocortisone in otic suspensions for use in the treatment of bacterial infections in the external auditory canal, including infections caused by medical procedures in the ear. Neomycin is also used in combination with polymyxin B sulfates and dexamethasone in ophthalmic preparations for use in the treatment of inflammatory conditions and infections in the eye. Neomycin is also available in over-the-counter topical products to prevent minor skin infections.

Neomycin mediates its bactericidal action by inhibiting bacterial protein synthesis, thereby suppressing the growth and survival of susceptible bacteria. Following oral administration, the duration of bactericidal activity of neomycin ranged from 48 to 72 hours. By decreasing colonic bacteria that produce ammonia, neomycin was shown to be effective as an adjunctive therapy in hepatic coma to improve neurologic symptoms.

Uses

Fluorometholone Acetate ophthalmic suspension is used for the treatment of-

Acute and chronic non-infectious conjunctivitis and keratitis of allergic origin.
Non-infectious inflammation of the anterior chamber of the eye (including anterior uveitis, episcleritis and scleritis).
Post-operative irritative conditions after strabismus, cataract and glaucoma surgery.

Neomycin is an aminoglycoside antibiotic agent used orally and topically to treat a wide variety of infections in the body.

Oral neomycin sulfate is indicated as an adjunctive therapy in hepatic coma (portal-system encephalopathy) by reducing ammonia-forming bacteria in the intestinal tract. It is strongly recommended that oral neomycin is only used in infections that are proven or strongly suspected to be caused by susceptible bacteria to reduce the risk of the development of drug-resistant bacteria.

Neomycin, in combination with polymyxin B sulfates and hydrocortisone in otic suspensions, is used in the treatment of superficial bacterial infections of the external auditory canal caused by organisms susceptible to the antibiotics. This otic formulation is also used in the treatment of infections of mastoidectomy and fenestration cavities caused by organisms susceptible to the antibiotics.

The ophthalmic solution containing neomycin in combination with polymyxin B sulfates and dexamethasone is used to treat steroid-responsive inflammatory ocular conditions for which a corticosteroid is indicated and where bacterial infection or a risk of bacterial infection exists.

Flurin N Eye is also used to associated treatment for these conditions: Anterior chamber inflammation, Conjunctivitis allergic, Corneal Inflammation, Inflammation, Ocular Inflammation, Ocular bacterial infectionsAcne pustular, Allergic Contact Dermatitis, Allergy Skin, Atopic Dermatitis (AD), Atopic Dermatitis (AD) of the external ear canal, Bacterial diarrhoea, Burns, Carbuncle, Cradle Cap, Dermatitis, Dermatitis, Contact, Dermatitis, Eczematous, Diarrhoea, Discoid Lupus Erythematosus (DLE), Ear infection bacterial, Ear infection bacterial caused by susceptible bacteria, Gastrointestinal Infections, Hepatic coma, Hidradenitis Suppurativa (HS), Hot Water Burns (Scalds), Impetigo, Impetigo contagious, Infantile Eczema, Infected Wounds, Infected skin ulcer, Infection of the outer ear caused by susceptible bacteria, Infectious diarrhea, Inflammatory Reaction caused by Acne, Intertrigo, Itching caused by Infection, Lichen Planus (LP), Localized Infection caused by susceptible bacteria, Nail infection, Neurodermatitis, Otitis Externa, Postoperative Wound Infection, Psoriasis Vulgaris (Plaque Psoriasis), Pustular Dermatosis, Radiodermatitis, Secondarily Infected Eczema, Secondary Bacterial Infection, Skin Burns, Skin Infections, Skin Infections, Bacterial, Skin Irritation, Skin Ulcer, Solar erythema, Abrasions, Blistering caused by Staphylococcus, Erythematous eruptions, Intertriginous erythema of the anogenital, Ocular bacterial infections caused by susceptible bacteria, Resistant to other corticosteroids Dermatosis, Susceptible Bacterial Infections

How Flurin N Eye works

There is no generally accepted explanation for the mechanism of action of ocular corticosteroids. However, corticosteroids are thought to act by the induction of phospholipase A2 inhibitory proteins, collectively called lipocortins. It is postulated that these proteins control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor, arachidonic acid. Arachidonic acid is released from membrane phospholipids by phospholipase A2. Their primary target is the cytosolic glucocorticoid receptor. After binding the receptor the newly formed receptor-ligand complex translocates itself into the cell nucleus, where it binds to many glucocorticoid response elements (GRE) in the promoter region of the target genes. The DNA bound receptor then interacts with basic transcription factors, causing the increase in expression of specific target genes.

Like other aminoglycoside antibiotic drugs, neomycin inhibits bacterial ribosomes by binding to the 30S ribosomal subunit of susceptible bacteria and disrupting the translational machinery of bacterial protein synthesis. Bacterial translation is normally initiated by the mRNA binding to the 30S ribosomal subunit and subsequent binding with 50S subunit for elongation.

Dosage

Flurin N Eye dosage

1 drop instilled into the conjunctival sac 2-4 times daily. During the initial 24 to 48 hours the dosage may be safely increased to 1 drop every hour. Care should be taken not to discontinue therapy prematurely. Shake well before use.

Side Effects

Glaucoma with optic nerve damage, visual acuity or field defects, cataract formation, secondary ocular infection following suppression of host immunity, perforation of the globe.

Toxicity

Side effects may include acute anterior uveitis and perforation of the globe. Keratitis, conjunctivitis, corneal ulcers, mydriasis, conjunctival hyperemia, loss of accommodation and ptosis have occasionally been reported following local use of corticosteroids. LD₅₀ = 234 mg/kg (rats)

The oral LD₅₀ of neomycin sulfate in mouse is > 8 g/kg. The subcutaneous LD₅₀ is 200 mg/kg in rat and 190 mg/kg in mouse. The intraperitoneal LD₅₀ in mouse is 305 mg/kg. The oral Lowest published toxic dose (TDLo) in woman is 12600 mg/kg/7D.

Because of low absorption, acute overdosage from oral neomycin is not likely to occur. However, prolonged administration of neomycin should be avoided because of the possibility of some systemic absorption and the risk of neurotoxicity, ototoxicity, and/or nephrotoxicity. Hemodialysis will remove neomycin from the blood. While nephrotoxicity and ototoxicity have been reported in otherwise patients without compromised renal function, the risk for developing these toxicities is increased in patients with renal impairment. Like other aminoglycosides, neomycin may cause fetal harm and total irreversible bilateral congenital deafness when administered in pregnant women.

Precaution

Shake well before using. If this product is used for 10 days or longer, intraocular pressure should be monitored.

Interaction

Specific drug interaction studies have not been conducted with Fluorometholone ophthalmic suspension.

Volume of Distribution

The small fraction of absorbed neomycin is rapidly distributed in the tissues. The amount of systemically absorbed neomycin is reported to increase cumulatively with each repeated dose administered until a steady state is reached.

Elimination Route

Neomycin is poorly absorbed from the gastrointestinal tract. Gastrointestinal absorption of the drug may be increased if inflammatory or ulcerative gastrointestinal disease is present.

Half Life

There is limited information on the half-life of neomycin.

Clearance

There is limited information on the clearance rate of neomycin.

Elimination Route

The small absorbed fraction of neomycin is excreted by the kidney. The unabsorbed portion of the drug is excreted unchanged in the feces.

Pregnancy & Breastfeeding use

Safety of the use of topical steroids during pregnancy and lactation has not been established. Fluorometholone ophthalmic suspension should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Contraindication

Hypersensitivity to any ingredient of the formulation.
Infectious conjunctivitis or keratitis.
Injuries and ulcerous processes of cornea, especially infections caused by virus, bacteria and fungi.
Dry eyes, especially keratoconjunctivitis sicca.
