5 WARNINGS AND PRECAUTIONS

• Brumeton Colloidale S Spray can produce reversible HPA axis suppression with the potential for glucocorticosteroid insufficiency during or after treatment. (5.1)
• Cushing's syndrome, hyperglycemia, and unmasking of latent diabetes mellitus can result from systemic absorption of topical corticosteroids. (5.1)
• Use of topical corticosteroids may require periodic evaluation for HPA axis suppression. (5.1)
• Modify use if HPA axis suppression develops. (5.1)
• High potency corticosteroids, large treatment surface areas, prolonged use, use of occlusive dressings, altered skin barrier, liver failure and young age may predispose patients to HPA axis suppression. (5.1)
• Pediatric patients may be more susceptible to systemic toxicity when treated with topical corticosteroids. (5.1, 8.4)

5.1 Hypothalamic-Pituitary-Adrenal (HPA) Axis Suppression and Other Unwanted Systemic Glucocorticoid Effects

Brumeton Colloidale S (Betamethasone) Spray can produce reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for glucocorticosteroid insufficiency. This may occur during or after withdrawal of treatment. Factors that predispose to HPA axis suppression include the use of high-potency corticosteroids, large treatment surface areas, prolonged use, use of occlusive dressings, altered skin barrier, liver failure, and young age.

Evaluation for HPA axis suppression may be done by using the adrenocorticotropic hormone (ACTH) stimulation test.

In a study including 48 evaluable subjects 18 years of age or older with moderate to severe plaque psoriasis, abnormal ACTH stimulation test results suggestive of adrenal suppression were identified in 5 out of 24 (20.8%) subjects after treatment with Brumeton Colloidale S (Betamethasone) Spray twice daily for 15 days. No subject (0 out of 24) had abnormal ACTH stimulation test results after treatment with Brumeton Colloidale S (Betamethasone) Spray twice daily for 29 days .

If HPA axis suppression is documented, gradually withdraw the drug, reduce the frequency of application, or substitute with a less potent corticosteroid. If signs and symptoms of steroid withdrawal occur, supplemental systemic corticosteroids may be required.

Systemic effects of topical corticosteroids may also manifest as Cushing’s syndrome, hyperglycemia, and glucosuria. These events are rare and generally occur after prolonged exposure to larger than recommended doses, particularly with high-potency topical corticosteroids.

Minimize the unwanted risks from endocrine effects by mitigating the risk factors favoring increased systemic bioavailability and by using the product as recommended .

Pediatric patients may be more susceptible to systemic toxicity due to their larger skin surface to body mass ratios. Use of Brumeton Colloidale S (Betamethasone) Spray is not recommended in pediatric patients .

5.2 Allergic Contact Dermatitis

Allergic contact dermatitis with corticosteroids is usually diagnosed by observing failure to heal rather than noting a clinical exacerbation. Corroborate such an observation with appropriate diagnostic patch testing. If irritation develops, discontinue the topical corticosteroid and institute appropriate therapy.

6 ADVERSE REACTIONS

The most common adverse reactions are application site reactions, including pruritus, burning and/or stinging, pain, and atrophy. (6.1)

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

In two randomized, multicenter, prospective vehicle-controlled clinical trials, subjects with moderate plaque psoriasis of the body applied Brumeton Colloidale S (Betamethasone) Spray or vehicle spray twice daily for 4 weeks. A total of 352 subjects applied Brumeton Colloidale S (Betamethasone) Spray and 180 subjects applied vehicle spray.

Adverse reactions that occurred in at least 1% of subjects treated with Brumeton Colloidale S (Betamethasone) Spray for up to 28 days are presented in Table 1.

Less common adverse reactions (with occurrence lower than 1% but higher than 0.1%) in subjects treated with Brumeton Colloidale S (Betamethasone) spray were application site reactions including telangiectasia, dermatitis, discoloration, folliculitis and skin rash, in addition to dysgeusia and hyperglycemia. These adverse reactions were not observed in subjects treated with vehicle.

6.2 Postmarketing Experience

Because adverse reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Postmarketing reports for local adverse reactions to topical corticosteroids have also included striae, irritation, dryness, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, hypertrichosis, and miliaria.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category C

There are no adequate and well-controlled studies in pregnant women. Brumeton Colloidale S Spray should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Brumeton Colloidale S (Betamethasone) dipropionate has been shown to be teratogenic in rabbits when given by the intramuscular route at doses of 0.05 mg/kg. The abnormalities observed included umbilical hernias, cephalocele, and cleft palate.

8.3 Nursing Mothers

Systemically administered corticosteroids appear in human milk and can suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. It is not known whether topical administration of corticosteroids can result in sufficient systemic absorption to produce detectable quantities in human milk. Because many drugs are excreted in human milk, caution should be exercised when Brumeton Colloidale S (Betamethasone) Spray is administered to a nursing woman.

8.4 Pediatric Use

Safety and effectiveness of Brumeton Colloidale S Spray in patients younger than 18 years of age have not been studied; therefore use in pediatric patients is not recommended. Because of a higher ratio of skin surface area to body mass, pediatric patients are at greater risk of systemic toxicity, including HPA axis suppression and adrenal insufficiency, when treated with topical drugs. [see Warnings and Precautions (5.1)]

Rare systemic effects such as Cushing's syndrome, linear growth retardation, delayed weight gain, and intracranial hypertension have been reported in pediatric patients, especially those with prolonged exposure to large doses of high potency topical corticosteroids.

Local adverse reactions including skin atrophy have also been reported with use of topical corticosteroids in pediatric patients.

8.5 Geriatric Use

Clinical studies of Brumeton Colloidale S (Betamethasone) Spray did not include sufficient numbers of subjects who were 65 years of age or older to determine whether they respond differently from younger subjects.

11 DESCRIPTION

Brumeton Colloidale S (Betamethasone) Spray contains 0.0643% Brumeton Colloidale S (Betamethasone) dipropionate (equivalent to 0.05% Brumeton Colloidale S (Betamethasone)), a synthetic, fluorinated corticosteroid.

The chemical name for Brumeton Colloidale S (Betamethasone) dipropionate is 9-fluoro-11(β), 17, 21-trihydroxy-16(β)-methylpregna-1,4-diene-3,20-dione-17,21-dipropionate. The empirical formula is C₂₈H₃₇FO₇ and the molecular weight is 504.6. The structural formula is shown below.

Each gram of Brumeton Colloidale S (Betamethasone) Spray contains 0.643 mg of Brumeton Colloidale S (Betamethasone) dipropionate USP (equivalent to 0.5 mg Brumeton Colloidale S (Betamethasone)) in a slightly thickened, white to off-white, oil-in-water, non-sterile emulsion with the following inactive ingredients:, butylated hydroxytoluene, cetostearyl alcohol, hydroxyethyl cellulose, methylparaben, mineral oil, oleyl alcohol, polyoxyl 20 cetostearyl ether, propylparaben, purified water, and sorbitan monostearate. Brumeton Colloidale S (Betamethasone) Spray is co-packaged with a manual spray pump for installation by the pharmacist prior to dispensing to patients.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Corticosteroids play a role in cellular signaling, immune function, inflammation, and protein regulation; however, the precise mechanism of action of Brumeton Colloidale S Spray in psoriasis is unknown.

12.2 Pharmacodynamics

Vasoconstrictor studies performed with Brumeton Colloidale S (Betamethasone) Spray in healthy subjects indicate that it is in the mid-range of potency as compared with other topical corticosteroids; however, similar blanching scores do not necessarily imply therapeutic equivalence.

The potential for HPA axis suppression by Brumeton Colloidale S (Betamethasone) Spray was evaluated in a study randomizing 52 adult subjects with moderate to severe plaque psoriasis. Brumeton Colloidale S (Betamethasone) Spray was applied twice daily for 15 or 29 days, in subjects with psoriasis involving a mean of 29.0% and 26.5% body surface area at baseline across the 2 treatment duration arms, respectively. Forty-eight (48) subjects were evaluated for HPA axis suppression at the end of treatment. The proportion of subjects demonstrating HPA axis suppression was 20.8% (5 out of 24) in subjects treated with Brumeton Colloidale S (Betamethasone) Spray for 15 days. No subjects (0 out of 24) treated with Brumeton Colloidale S (Betamethasone) Spray for 29 days had HPA axis suppression. In this study HPA axis suppression was defined as serum cortisol level ≤18 mcg/dL 30-minutes post-cosyntropin stimulation. In the 4 subjects with available follow-up values, all subjects had normal ACTH stimulation tests at follow-up.

12.3 Pharmacokinetics

The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings.

Topical corticosteroids are absorbed through normal intact skin. Inflammation and/or other disease processes in the skin may increase percutaneous absorption.

Plasma concentrations of Brumeton Colloidale S (Betamethasone) dipropionate, betamethasone-17-propionate, and Brumeton Colloidale S (Betamethasone) were measured at baseline, and before and after the last dose (1, 3, and 6 hours) in the HPA axis suppression trial in subjects with psoriasis [see Clinical Pharmacology (12.2)]. The majority of subjects had no measurable plasma concentration (<5.00 pg/mL) of Brumeton Colloidale S (Betamethasone) dipropionate, while the metabolites, betamethasone-17-propionate and Brumeton Colloidale S (Betamethasone), were detected in the majority of subjects (Table 2). There was high variability in the data but there was a trend toward higher systemic exposure at Day 15 and lower systemic exposure at Day 29.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Long-term animal studies have not been performed to evaluate the carcinogenic potential of Brumeton Colloidale S (Betamethasone) dipropionate.

In a 90-day repeat-dose toxicity study in rats, topical administration of Brumeton Colloidale S (Betamethasone) dipropionate spray formulation at dose concentrations of 0.05% and 0.1% (providing dose levels up to 0.5 mg/kg/day in males and 0.25 mg/kg/day in females) resulted in a toxicity profile consistent with long-term exposure to corticosteroids including reduced body weight gain, adrenal atrophy, and histological changes in bone marrow, thymus and spleen indicative of severe immune suppression. A no observable adverse effect level (NOAEL) could not be determined in this study. Although the clinical relevance of the findings in animals to humans is not clear, sustained glucocorticoid-related immune suppression may increase the risk of infection and possibly the risk of carcinogenesis.

Brumeton Colloidale S (Betamethasone) was negative in the bacterial mutagenicity assay (Salmonella typhimurium and Escherichia coli), and in the mammalian cell mutagenicity assay (CHO/HGPRT). It was positive in the in vitro human lymphocyte chromosome aberration assay, and equivocal in the in vivo mouse bone marrow micronucleus assay.

Studies in rabbits, mice, and rats using intramuscular doses up to 1, 33, and 2 mg/kg, respectively, resulted in dose-related increases in fetal resorptions in rabbits and mice.

14 CLINICAL STUDIES

Two multi-center, randomized, double-blind, vehicle-controlled clinical trials were conducted in subjects aged 18 years and older with moderate plaque psoriasis. In both trials, randomized subjects applied Brumeton Colloidale S (Betamethasone) Spray or vehicle spray to the affected areas twice daily for 28 days. Enrolled subjects had body surface area of involvement between 10% to 20%, and an Investigator Global Assessment (IGA) score of 3 (moderate).

Efficacy was assessed as the proportion of subjects who were considered a treatment success (defined as having an IGA score of 0 or 1 [clear or almost clear] and at least a 2-grade reduction from baseline). Table 3 presents the efficacy results at Day 15 and Day 29.

CLINICAL PHARMACOLOGY

Corticosteroids suppress the inflammatory response to a variety of agents and they probably delay or slow healing. Since corticosteroids may inhibit the body's defense mechanism against infection, a concomitant antibacterial drug may be used when this inhibition is considered to be clinically significant in a particular case.

When a decision to administer both a corticosteroid and an antibacterial is made, the administration of such drugs in combination has the advantage of greater patient compliance and convenience, with the added assurance that the appropriate dosage of both drugs is administered. When both types of drugs are in the same formulation, compatibility of ingredients is assured and the correct volume of drug is delivered and retained. The relative potency of corticosteroids depends on the molecular structure, concentration and release from the vehicle.

Microbiology

Brumeton Colloidale S (Sulfacetamide Sodium) sodium exerts a bacteriostatic effect against susceptible bacteria by restricting the synthesis of folic acid required for growth through competition with p-aminobenzoic acid.

Some strains of these bacteria may be resistant to Brumeton Colloidale S (Sulfacetamide Sodium) or resistant strains may emerge in vivo.

The anti-infective component in these products is included to provide action against specific organisms susceptible to it. Brumeton Colloidale S (Sulfacetamide Sodium) sodium is active in vitro against susceptible strains of the following microorganisms: Escherichia coli, Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus (viridans group), Haemophilus influenzae, Klebsiella species, and Enterobacter species. This product does not provide adequate coverage against: Neisseria species, Pseudomonas species, and Serratia marcescens.

INDICATIONS AND USAGE

Brumeton Colloidale S (Sulfacetamide Sodium) ^® ophthalmic suspension is a steroid/anti-infective combination drug indicated for steroid-responsive inflammatory ocular conditions for which a corticosteroid is indicated and where superficial bacterial ocular infection or a risk of bacterial ocular infection exists.

Ocular corticosteroids are indicated in inflammatory conditions of the palpebral and bulbar conjunctiva, cornea, and anterior segment of the globe where the inherent risk of corticosteroid use in certain infective conjunctivitides is accepted to obtain diminution in edema and inflammation. They are also indicated in chronic anterior uveitis and corneal injury from chemical, radiation or thermal burns or penetration of foreign bodies.

The use of a combination drug with an anti-infective component is indicated where the risk of superficial ocular infection is high or where there is an expectation that potentially dangerous numbers of bacteria will be present in the eye.

The particular antibacterial drug in this product is active against the following common bacterial eye pathogens: Escherichia coli, Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus (viridans group), Haemophilus influenzae, Klebsiella species, and Enterobacter species. This product does not provide adequate coverage against: Neisseria species, Pseudomonas species, and Serratia marcescens.

A significant percentage of staphylococcal isolates are completely resistant to sulfa drugs.

CONTRAINDICATIONS

Brumeton Colloidale S (Sulfacetamide Sodium) ^® ophthalmic suspension is contraindicated in most viral diseases of the cornea and conjunctiva including epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, and varicella, and also in mycobacterial infection of the eye and fungal diseases of ocular structures.

Brumeton Colloidale S (Sulfacetamide Sodium) ^® ophthalmic suspension is also contraindicated in individuals with known or suspected hypersensitivity to any of the ingredients of this preparation, to other sulfonamides and to other corticosteroids. (Hypersensitivity to the antimicrobial component occurs at a higher rate than for other components.)

WARNINGS

NOT FOR INJECTION INTO THE EYE.

Prolonged use of corticosteroids may result in posterior subcapsular cataract formation and may increase intraocular pressure in susceptible individuals, resulting in ocular hypertension/glaucoma with damage to the optic nerve, defects in visual acuity and fields of vision.

If the product is used for 10 days or longer, intraocular pressure should be routinely monitored even though it may be difficult in children and uncooperative patients. Corticosteroids should be used with caution in the presence of glaucoma. Intraocular pressure should be checked frequently.

The use of steroids after cataract surgery may delay healing and increase the incidence of bleb formation.

In those diseases causing thinning of the cornea or sclera, perforation has been known to occur with the use of topical corticosteroids.

In acute purulent conditions of the eye, corticosteroids may mask infection or enhance existing infection.

The use of ocular corticosteroids may prolong the course and may exacerbate the severity of many viral infections of the eye (including herpes simplex). Employment of corticosteroid medication in the treatment of herpes simplex requires great caution.

Prolonged use of Brumeton Colloidale S (Sulfacetamide Sodium) ^® ophthalmic suspension may suppress the host response and thus increase the hazard of secondary ocular infections.

Prolonged use of topical anti-bacterial agents may give rise to overgrowth of nonsusceptible organisms including fungi.

A significant percentage of staphylococcal isolates are completely resistant to sulfonamides.

Acute anterior uveitis may occur in susceptible individuals, primarily Blacks.

Fatalities have occurred, although rarely, due to severe reactions to sulfonamides including Stevens-Johnson syndrome, toxic epidermal necrolysis, fulminant hepatic necrosis, agranulocytosis, aplastic anemia and other blood dyscrasias. Sensitization may recur when a sulfonamide is readministered, irrespective of the route of administration.

If signs of hypersensitivity, skin rash, or other serious reactions occur, discontinue use of this preparation. Cross-sensitivity among corticosteroids has been demonstrated.

PRECAUTIONS

General

The initial prescription and renewal of the medication order beyond 20 milliliters of the suspension should be made by a physician only after examination of the patient with the aid of magnification, such as slit lamp biomicroscopy and, where appropriate, fluorescein staining. If signs and symptoms fail to improve after two days, the patient should be re-evaluated.

The possibility of fungal infections of the cornea should be considered after prolonged corticosteroid dosing. Fungal cultures should be taken when appropriate.

Use with caution in patients with severe dry eye.

The p-aminobenzoic acid present in purulent exudates competes with sulfonamides and can reduce their effectiveness.

Information for Patients

If inflammation or pain persists longer than 48 hours or becomes aggravated, the patient should be advised to discontinue use of the medication and consult a physician.

Contact lenses should not be worn during the use of this product.

This product is sterile when packaged. To prevent contamination, care should be taken to avoid touching the applicator tip to eyelids or to any other surface. The use of this bottle by more than one person may spread infection. Keep bottle tightly closed when not in use. Protect from light. Sulfonamide solutions darken on prolonged standing and exposure to heat and light. Do not use if solution has darkened. Yellowing does not affect activity. Keep out of the reach of children.

Laboratory Tests

Eyelid cultures and tests to determine the susceptibility of organisms to Brumeton Colloidale S (Sulfacetamide Sodium) may be indicated if signs and symptoms persist or recur in spite of the recommended course of treatment with Brumeton Colloidale S (Sulfacetamide Sodium) ^® ophthalmic suspension.

Drug Interactions

Brumeton Colloidale S ^® ophthalmic suspension is incompatible with silver preparations. Local anesthetics related to p-aminobenzoic acid may antagonize the action of the sulfonamides.

Carcinogenesis, Mutagenesis, Impairment of Fertility

Prednisolone has been reported to be noncarcinogenic. Long-term animal studies for carcinogenic potential have not been performed with Brumeton Colloidale S (Sulfacetamide Sodium).

One author detected chromosomal nondisjunction in the yeast Saccharomyces cerevisiae following application of Brumeton Colloidale S (Sulfacetamide Sodium) sodium. The significance of this finding to topical ophthalmic use of Brumeton Colloidale S (Sulfacetamide Sodium) sodium in the human is unknown.

Mutagenic studies with prednisolone have been negative. Studies on reproduction and fertility have not been performed with Brumeton Colloidale S (Sulfacetamide Sodium). A long-term chronic toxicity study in dogs showed that high oral doses of prednisolone prevented estrus. A decrease in fertility was seen in male and female rats that were mated following oral dosing with another glucocorticosteroid.

Pregnancy

Teratogenic Effects

Animal reproduction studies have not been conducted with Brumeton Colloidale S sodium. Prednisolone has been shown to be teratogenic in rabbits, hamsters, and mice. In mice, prednisolone has been shown to be teratogenic when given in doses 1 to 10 times the human ocular dose. Dexamethasone, hydrocortisone and prednisolone were ocularly applied to both eyes of pregnant mice five times per day on days 10 through 13 of gestation. A significant increase in the incidence of cleft palate was observed in the fetuses of the treated mice. There are no adequate well-controlled studies in pregnant women dosed with corticosteroids.

Kernicterus may be precipitated in infants by sulfonamides being given systemically during the third trimester of pregnancy. It is not known whether Brumeton Colloidale S (Sulfacetamide Sodium) sodium can cause fetal harm when administered to a pregnant woman or whether it can affect reproductive capacity.

Brumeton Colloidale S (Sulfacetamide Sodium) ^® ophthalmic suspension should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Nursing Mothers

It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in human milk. Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. Systemically administered sulfonamides are capable of producing kernicterus in infants of lactating women. Because of the potential for serious adverse reactions in nursing infants from Brumeton Colloidale S (Sulfacetamide Sodium) sodium and prednisolone acetate ophthalmic suspensions, a decision should be made whether to discontinue nursing or to discontinue the medication.

Pediatric Use

Safety and effectiveness in pediatric patients below the age of 6 years have not been established.

ADVERSE REACTIONS

The following adverse reactions have been identified during use of Brumeton Colloidale S (Sulfacetamide Sodium) ^® ophthalmic suspension. Because reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Adverse reactions have occurred with corticosteroid/antibacterial combination drugs which can be attributed to the corticosteroid component, the antibacterial component, or the combination.

Reactions occurring with Brumeton Colloidale S (Sulfacetamide Sodium) ^® ophthalmic suspension include: cataract, dizziness, eye discharge, eyelid edema, eyelid erythema, eye irritation, eye pain, eye pruritus, and hypersensitivity including rash, skin pruritus, urticaria, ocular hyperemia, and visual disturbance (blurry vision).

Reactions occurring most often from the presence of the antibacterial ingredient are allergic sensitizations. Fatalities have occurred, although rarely, due to severe reactions to sulfonamides including Stevens-Johnson syndrome, toxic epidermal necrolysis, fulminant hepatic necrosis, agranulocytosis, aplastic anemia, and other blood dyscrasias.

The reactions due to the corticosteroid component in decreasing order of frequency are: delayed wound healing, elevation of intraocular pressure (IOP) with possible development of glaucoma and infrequent optic nerve damage, and posterior subcapsular cataract formation.

Although systemic effects are extremely uncommon, there have been rare occurrences of systemic hypercorticoidism after use of topical corticosteroids.

Corticosteroid-containing preparations can also cause acute anterior uveitis or perforation of the globe. Mydriasis, loss of accommodation and ptosis have occasionally been reported following local use of corticosteroids.

Secondary Infection

The development of secondary infection has occurred after use of combinations containing corticosteroids and antibacterials. Fungal and viral infections of the cornea are particularly prone to develop coincidentally with long-term applications of corticosteroid. The possibility of fungal invasion must be considered in any persistent corneal ulceration where corticosteroid treatment has been used.

Secondary bacterial ocular infection following suppression of host responses also occurs.

DOSAGE AND ADMINISTRATION

SHAKE WELL BEFORE USING. Two drops should be instilled into the conjunctival sac every four hours during the day and at bedtime.
