Classes

Plain Topical Corticosteroids

Administration

Halcinonide products are for external application to the skin only. Not for ophthalmic or intravaginal use.

Topical Administration

Occlusive Dressing Technique:
For the solution or ointment, apply to the lesion leaving a thin film.
For the cream, gently rub a small amount into the lesion until it disappears then reapply, leaving a thin coating on the lesion.
After application cover the lesion with a pliable, nonporous film and seal the edges.
If additional moisture is needed, apply a dampened clean cotton cloth before the nonporous film is applied or briefly wet the affected area with water immediately prior to applying the medication.
The frequency of dressing changes is best determined on an individual basis. It may be convenient to apply halcinonide under an occlusive dressing in the evening and remove the dressing in the morning (i.e. 12-hour occlusion). When utilizing the 12-hour occlusion regimen, additional halcinonide should be applied, without occlusion, during the day.
Reapplication is essential at each dressing change.
If an infection develops, the use of occlusive dressings should be discontinued and appropriate antimicrobial therapy instituted.

Cream/Ointment/Lotion Formulations

Cream and ointment:
Apply halcinonide cream or ointment sparingly in a thin film and rub gently.
When applying to hairy areas, part the hair and apply a small amount to the affected area; rub in gently.
Until the medication has dried, do not wash or rub the treated area or apply clothing.
Hair may be washed as usual during the treatment period but not immediately after applying the medication.

Other Topical Formulations

Solution:
Apply halcinonide solution sparingly in a thin film and rub gently.
When applying to hairy areas, part the hair and apply a small amount to the affected area; rub in gently.
Until the medication has dried, do not wash or rub the treated area or apply clothing.
Hair may be washed as usual during the treatment period but not immediately after applying the medication.

Description

High-potency fluorinated topical corticosteroid
Used for moderate-severe corticosteroid-responsive dermatoses, including psoriasis
Generally use for short durations due to potential for systemic effects

Dosage And Indications
For the treatment of corticosteroid-responsive dermatoses, including atopic dermatitis, localized vitiligo, eczema, phimosis, lichen planus, and localized bullous pemphigoid. Topical dosage Adults

Apply a thin layer topically to the affected skin area(s) 2 to 3 times daily.

Children and Adolescents

Apply a thin layer topically to the affected skin area(s) 2 to 3 times daily.

For the treatment of psoriasis. Topical dosage Adults

Apply a thin layer to the affected skin area(s) 2 to 3 times daily. The duration of the therapy depends on factors such as the topical corticosteroid potency, disease severity and anatomic location, and age. After improvement, may consider transitioning to lower-potency corticosteroid, using intermittent therapy, and combining treatment with noncorticosteroidal agents. Taper by reducing use to every other day, then twice weekly, then discontinue if adequate control is maintained.

Children and Adolescents

Apply a thin layer to the affected skin area(s) 2 to 3 times daily. Guidelines recommend topical corticosteroids as monotherapy for short-term treatment of localized psoriasis.

Dosing Considerations
Hepatic Impairment

Specific guidelines for dosage adjustments in hepatic impairment are not available; it appears that no topical dosage adjustments are needed.

Renal Impairment

Specific guidelines for dosage adjustments in renal impairment are not available; it appears that no topical dosage adjustments are needed.

Drug Interactions

There are no drug interactions associated with Halcinonide products.

How Supplied

Halcinonide/Halog/Halog -E Topical Cream: 0.1%
Halog Topical Ointment: 0.1%
Halog Topical Sol: 0.1%

Maximum Dosage

NOTE: In general, corticosteroid dosage must be individualized and is highly variable depending on the nature and severity of the disease, dosage form selected, and patient age and response.

Mechanism Of Action

Topical corticosteroids exhibit anti-inflammatory, antipruritic, and vasoconstrictive properties. At the cellular level, corticosteroids induce peptides called lipocortins. Lipocortins antagonize phospholipase A2, an enzyme which causes the breakdown of leukocyte lysosomal membranes to release arachidonic acid. This action decreases the subsequent formation and release of endogenous inflammatory mediators including prostaglandins, kinins, histamine, liposomal enzymes and the complement system. Early anti-inflammatory effects of topical corticosteroids include the inhibition of macrophage and leukocyte movement and activity in the inflamed area by reversing vascular dilation and permeability. Later inflammatory processes such as capillary production, collagen deposition, keloid (scar) formation also are inhibited by corticosteroids. Clinically, these actions correspond to decreased edema, erythema, pruritus, plaque formation and scaling of the affected skin.

Pharmacokinetics

Halcinonide is applied topically as cream, ointment or solution. Because halcinonide is fluorinated and also contains a substituted 17-hydroxyl group, it is not metabolized in the skin. Repeated application results in a cumulative depot effect in the skin, which may lead to a prolonged duration of action and increased systemic absorption. Halcinonide is metabolized primarily in the liver and excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile.

Topical Route

The extent of percutaneous absorption of the topical corticosteroids is dependent on many factors, including the pharmaceutical vehicle and the integrity of the epidermis. Absorption after topical application of halcinonide is increased in areas that have skin damage, inflammation, or occlusion, or in areas where the stratum corneum is thin such as the eyelids, genitalia, axillae, and face. The use of occlusive dressings with the application of halcinonide enhances penetration into the skin, and may increase the chance of systemic absorption. Ointments have a hydrating effect, are lipophilic, and may enhance the penetration of halcinonide into the skin. Halcinonide solutions also have enhanced topical penetration versus cream preparations. Anti-inflammatory effects are usually not seen for hours after halcinonide application, since the mechanism of action requires alterations in synthesis of proteins. Repeated application results in a cumulative depot effect in the skin, which may lead to a prolonged duration of action and increased systemic absorption.

Pregnancy And Lactation
Pregnancy

There are no adequate and well-controlled studies of topical application of halcinonide during pregnancy. Topical corticosteroids, including halcinonide, should not be used in large amounts, on large areas, or for prolonged periods of time in pregnant women. Guidelines recommend mild to moderate potency agents over potent corticosteroids, which should be used in short durations. Fetal growth restriction and a significantly increased risk of low birthweight has been reported with use of potent or very potent topical corticosteroids during the third trimester, particularly when using more than 300 grams. Corticosteroids are generally teratogenic in laboratory animals when administered systemically at relatively low dosage levels. The more potent corticosteroids have been shown to be teratogenic after dermal application in laboratory animals.

It is not known whether topical administration of halcinonide could result in sufficient systemic absorption to produce detectable quantities in breast milk. However, most dermatologists stress that topical corticosteroids can be safely used during lactation and breast-feeding. If applied topically, care should be used to ensure the infant will not come into direct contact with the area of application, such as the breast. Increased blood pressure has been reported in an infant whose mother applied a high potency topical corticosteroid ointment directly to the nipples. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally ingested drug, healthcare providers are encouraged to report the adverse effect to the FDA.
