Introduction

A synthetic corticosteroid.

Uses for Alclometasone

Corticosteroid-responsive Dermatoses

Relief of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses.

Generally most effective in acute or chronic dermatoses (e.g., seborrheic or atopic dermatitis, localized neurodermatitis, anogenital pruritus, psoriasis, late phase of allergic contact dermatitis, inflammatory phase of xerosis).

Topical therapy generally preferred over systemic therapy; fewer associated adverse systemic effects.

Topical therapy generally only controls manifestations of dermatoses; eliminate cause if possible.

Topical efficacy may be increased by using a higher concentration or occlusive dressing therapy. (See Administration with Occlusive Dressing under Dosage and Administration.)

Response may vary from one topical corticosteroid preparation to another.

Anti-inflammatory activity may vary considerably depending on the vehicle, drug concentration, site of application, disease, and individual patient.

Manufacturers state that alclometasone should not be used for the treatment of acne, rosacea, or perioral dermatitis.

Alclometasone dipropionate 0.05% cream and ointment are considered to have low-to-medium range potency.

Alclometasone Dosage and Administration

General

Administration

Topical Administration

For dermatologic use only; avoid contact with eyes.

Apply creams and ointments topically to the skin or scalp.

The area of skin to be treated may be thoroughly cleansed before topical application to reduce the risk of infection; however, some clinicians believe that, unless an occlusive dressing is used, cleansing of the treated area is unnecessary and may be irritating.

Apply cream or ointment sparingly in a thin film and rub gently into the affected area.

After a favorable response is achieved, frequency of application or concentration (strength) may be decreased to the minimum necessary to maintain control and to avoid relapse; discontinue if possible.

Administration with Occlusive Dressing

Occlusive dressings may be used for severe or resistant dermatoses (e.g., psoriasis). (See Occlusive Dressings under Cautions.)

Soak or wash the affected area to remove scales; apply a thin film of cream or ointment; rub gently into the lesion; and apply another thin film. Cover affected area with a thin, pliable plastic film and seal it to adjacent normal skin with adhesive tape or hold in place with a gauze or elastic bandage.

If affected area is moist, incompletely seal the edges of the plastic film or puncture the film to allow excess moisture to escape. For added moisture in dry lesions, apply cream or ointment and cover with a dampened cloth before the plastic film is applied or briefly soak the affected area in water before application of the drug and plastic film.

Thin polyethylene gloves may be used on the hands and fingers, plastic garment bags may be used on the trunk or buttocks, a tight shower cap may be used for the scalp, or whole-body suits may be used instead of plastic film to provide occlusion.

Frequency of occlusive dressing changes depends on the condition being treated; cleansing of the skin and reapplication of the corticosteroid are essential at each dressing change.

Occlusive dressing is usually left in place for 12–24 hours and therapy is repeated as needed. Although occlusive dressing may be left in place for 3–4 days at a time in resistant conditions, most clinicians recommend intermittent use of occlusive dressings for 12 hours daily to reduce the risk of adverse effects (particularly infection) and systemic absorption and for greater convenience.

The drug and an occlusive dressing may be used at night, and the drug or a bland emollient may be used without an occlusive dressing during the day.

In patients with extensive lesions, sequential occlusion of only one portion of the body at a time may be preferable to whole-body occlusion. (See Occlusive Dressings under Cautions.)

Dosage

Pediatric Patients

Administer the least amount of topical preparations that provide effective therapy. (See Pediatric Use under Cautions.)

Corticosteroid-responsive Dermatoses
Topical

Children ≥1 year of age: Apply cream or ointment sparingly 2–3 times daily.

Cautions for Alclometasone

Contraindications

Warnings/Precautions

Sensitivity Reactions

Allergic contact dermatitis may manifest as failure to heal rather than irritation as occurs with other topical preparations that do not contain corticosteroids; confirm with diagnostic patch testing.

General Precautions

Hypothalamic-Pituitary-Adrenal Axis Suppression

Topically applied corticosteroids can be absorbed in sufficient amounts to reversibly suppress the HPA axis.

Perform periodic HPA-axis evaluation by appropriate testing (e.g., ACTH stimulation, morning plasma cortisol, urinary free cortisol), especially in patients applying a topical corticosteroid to a large surface area or to areas under occlusion.

If HPA-axis suppression occurs, withdraw the drug, reduce the frequency of application, and/or substitute a less potent corticosteroid.

HPA-axis function recovery generally is prompt and complete following drug discontinuance.

Rarely, glucocorticosteroid insufficiency may require systemic corticosteroid therapy.

Systemic Effects

Systemic absorption following topical administration may result in manifestations of Cushing’s syndrome, hyperglycemia, and glucosuria in some patients.

Adverse systemic effects may occur when corticosteroids are used on large areas of the body, for prolonged periods of time, with an occlusive dressing, and/or concurrently with other corticosteroid-containing preparations.

Infants and children may be more susceptible to adverse systemic effects. (See Pediatric Use under Cautions.)

Local Effects

Possible adverse local reactions (e.g., burning, itching, irritation, dryness, folliculitis, hypertrichosis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, maceration of the skin, secondary infection, skin atrophy, striae, miliaria); may occur more frequently with the use of occlusive dressings, especially with prolonged therapy.

Prolonged use of topical corticosteroids may cause atrophy of the epidermis and subcutaneous tissue; these effects are most likely to occur (even with short-term use) in intertriginous (e.g., axilla, groin), flexor, and facial areas.

If irritation occurs, discontinue drug and institute appropriate therapy.

Skin Infection

If concurrent skin infection is present or develops, initiate appropriate anti-infective therapy. If infection does not respond promptly, discontinue topical corticosteroid therapy until the infection has been controlled.

When topical corticosteroids and topical anti-infectives are used concomitantly, consider that the corticosteroid may mask clinical signs of bacterial, fungal, or viral infections; prevent recognition of ineffectiveness of the anti-infective; or suppress hypersensitivity reactions to ingredients in the formulation. In addition, consider the cautions, precautions, and contraindications associated with the anti-infective. (See Occlusive Dressings under Cautions.)

Some manufacturers state that topical corticosteroids are contraindicated in patients with tuberculosis of the skin, dermatologic fungal infections, and cutaneous or systemic viral infection (including vaccinia and varicella and herpes simplex of the eye or adjacent skin). However, most clinicians believe topical corticosteroids can be used with caution if the infection is treated.

Occlusive Dressings

Adverse systemic corticosteroid effects may occur with use of occlusive dressings on large areas of the body and for prolonged periods of time; monitor accordingly. (See Hypothalamic-Pituitary-Adrenal Axis Suppression and also see Systemic Effects, under Cautions.)

Adverse local reactions may occur more frequently with the use of occlusive dressings, especially with prolonged therapy. (See Local Effects under Cautions.)

Do not use occlusive dressings on weeping or exudative lesions.

Do not use occlusive dressings in patients with primary skin infection.

Remove occlusive dressings covering large areas if body temperature increases; thermal homeostasis may be impaired.

Use plastic occlusive material with care to avoid the risk of suffocation.

Specific Populations

Pregnancy

Category C.

Lactation

Not known whether topical alclometasone is distributed into milk. Caution advised if topical alclometasone is used.

Pediatric Use

Safety and efficacy not established in children <1 year of age.

Do not use for the treatment of diaper dermatitis; tight-fitting diapers or plastic pants should not be used on a child being treated with alclometasone in the diaper area, since such garments may constitute occlusive dressings.

Children are more susceptible to topical corticosteroid-induced HPA-axis suppression and Cushing’s syndrome than mature individuals because of a greater skin surface area-to-body weight ratio, especially when topical corticosteroids are applied to >20% of body surface area. The risk of adrenal suppression appears to increase with decreasing age. (See Systemic Effects under Cautions.)

Manifestations of adrenal suppression in children include linear growth retardation, delayed weight gain, low plasma cortisol concentrations, and lack of response to corticotropin (ACTH) stimulation.

Children also are at greater risk of glucocorticoid insufficiency during and/or after withdrawal of treatment.

Intracranial hypertension has occurred in children; manifestations include bulging fontanelles, headaches, and bilateral papilledema.

Striae have been reported in children treated inappropriately with topical corticosteroids.

Topical corticosteroid therapy in children should be limited to the minimum amount necessary for therapeutic efficacy; chronic topical corticosteroid therapy may interfere with growth and development.

Geriatric Use

Response in limited number of patients ≥65 years of age does not appear to differ from that in younger adults.

Common Adverse Effects

Burning, itching, erythema, irritation,, dryness, papular rash, folliculitis, acneiform eruptions, hypopigmentation , perioral dermatitis, allergic contact dermatitis, secondary infection, skin atrophy, striae, miliaria.

Specific Drugs and Laboratory Tests

Drug or Test

Interaction

Concurrent use of corticosteroids reportedly may result in false-negative results

Alclometasone Pharmacokinetics

Absorption

Bioavailability

Topically applied alclometasone can be absorbed through normal intact skin.

Percutaneous penetration varies among individuals and can be altered by using occlusive dressings, high corticosteroid concentrations, and certain vehicles.

Only minimal amounts of topical corticosteroid reach the dermis and subsequently the systemic circulation after application to most normal skin areas; more absorption occurs from the scrotum, axilla, eyelid, face, and scalp than from the forearm, knee, elbow, palm, and sole.

Absorption is markedly increased by loss of the skin’s keratin layer and by inflammation and/or diseases of the epidermal barrier (e.g., psoriasis, eczema).

Distribution

Extent

Not known whether topical alclometasone is distributed into milk.

Elimination

Metabolism

Once absorbed through the skin, topically applied corticosteroids are metabolized primarily in the liver.

Elimination Route

Topical corticosteroids and metabolites are excreted by the kidneys and, to a lesser extent, in bile.

Stability

Storage

Topical

Cream and ointment: 2–30°C. Some manufacturers state 20–25°C. Consult product information for specific recommendations.
