Overview

Hydrocortisone or synthetic derivatives of hydrocortisone are used topically as anti-inflammatory agents.

Tazarotene is a synthetic acetylenic retinoid.

Tazarotene is a synthetic acetylenic retinoid. Tazarotene is a prodrug and exhibits no pharmacologic activity until hydrolyzed to its active metabolite tazarotenic acid. Tazarotenic acid has pharmacologic actions similar to those of other retinoids (e.g., tretinoin, isotretinoin).

However, unlike these drugs, tazarotenic acid has been shown to have relatively selective affinity for specific nuclear retinoic acid receptor (RAR) proteins (e.g., RARbeta, RARgamma) that appear to enhance gene transcription. RARgamma is the predominant RAR species expressed in human epidermis and therefore may be the primary molecular target of retinoid action in adult human skin. Tazarotenic acid does not bind to retinoid X receptors (RXRs), which work in conjunction with RARs but appear to affect a variety of hormonal pathways and therefore may be involved in producing adverse effects of retinoid therapy.

The exact mechanism(s) of action of tazarotene in the treatment of psoriasis has not been determined. Once hydrolyzed to tazarotenic acid, the drug appears to affect expression of genes that modulate cell (e.g., epidermal) differentiation, proliferation, and inflammation, leading to normalization of keratinocyte differentiation and a reduction in cellular hyperproliferation and inflammation. Although the exact mechanism(s) of action of tazarotene in the treatment of acne is not fully understood, apparent modulation of follicular keratinization, cell proliferation, and inflammation by tazarotenic acid results in inhibition of corneocyte accumulation and cohesion and a reduction in inflammatory and noninflammatory acne lesions.

The exact mechanism(s) of action of tazarotene in the palliative management of dermatologic changes (e.g., fine wrinkling, mottled hypopigmentation or hyperpigmentation, and benign lentigines) associated with photodamage has not been established. However, data from a histologic study in patients with fine wrinkling and mottled hyperpigmentation indicate that therapy with tazarotene 0.1% cream for 24 weeks may be associated with an increase in the number of granular cell layers and an increased incidence of epidermal edema; the clinical relevance of these changes is unknown.

USES: This medication is a combination product used to treat a certain skin condition (psoriasis). It contains 2 ingredients: halobetasol and tazarotene. Halobetasol is a very strong (super-high potency) corticosteroid.

It helps reduce the itching, redness, scaling, and swelling that can occur with this condition. Tazarotene is a retinoid product (related to vitamin A) that works by affecting the growth of skin cells.

  • Plaque Psoriasis

Dosing

Application of tazarotene cream or gel may cause a transient feeling of pruritus, burning, or stinging. (See Cautions: Precautions and Contraindications.) If irritation is excessive, tazarotene should be discontinued temporarily until the integrity of the skin is restored, or dosing of the drug should be reduced to a lower concentration (in patients with psoriasis) or to an interval the patient can tolerate; tazarotene therapy may be resumed, or the drug concentration or frequency of application increased, as therapy with the drug becomes more tolerable. Frequency of dosing, therapeutic response, and skin tolerance should be monitored carefully during tazarotene therapy. The efficacy of reduced dosing frequencies (i.e., less than once daily) has not been established.

Safe use of tazarotene gel over more than 20% of body surface area has not been established.

For dermatologic use, topical corticosteroids are available in various dosage forms including creams, dressings (tape), foams, gels, lotions, ointments, solutions, and aerosols (suspensions). The choice of a dosage form depends on the location of the lesion and the condition being treated. Lotions are probably best for the treatment of weeping eruptions, especially in areas subject to chafing such as the axilla, foot, and groin. Lotions, gels, and aerosols may be used on hairy areas, particularly the scalp. Creams are suitable for most dermatoses, but ointments, which may also provide some occlusion, are usually used for the treatment of dry, scaly lesions. Because certain areas of the body may be more susceptible to atrophic changes than others following treatment with corticosteroids, certain topical corticosteroid preparations (e.g., betamethasone dipropionate 0.05% gel; clobetasol propionate 0.05% cream, foam, gel, lotion, solution, or shampoo; hydrocortisone valerate 0.2% cream; mometasone furoate 0.1% cream, lotion, or ointment) should not be applied to the face or intertriginous areas (e.g., axilla, groin).

Because the formulation of dermatologic corticosteroid products affects percutaneous penetration and subsequent activity of the drug, extemporaneous preparation or dilution of most commercially available products with another vehicle may result in decreased effectiveness.

The area of skin to be treated may be thoroughly cleansed before topical application of corticosteroids 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. Topical corticosteroids are generally applied sparingly in thin films and rubbed gently into the affected area 1-4 times daily. When a favorable response is achieved, the frequency of application or concentration of the corticosteroid is reduced to the minimum necessary to maintain control and avoid relapse and, if possible, the drug should be discontinued.

For occlusive dressing therapy, the affected area is soaked or washed to remove scales and a corticosteroid cream, lotion, or ointment is applied in a thin film or is rubbed gently into the lesion and another thin film applied. After applying the corticosteroid, the affected area is covered with a thin, pliable plastic film which is sealed to adjacent normal skin with adhesive tape or held in place by a gauze or elastic bandage. If the affected area is moist, the edges of the plastic film may be incompletely sealed or the film may be punctured to allow excess moisture to escape. For added moisture in dry lesions, the corticosteroid may be covered with a dampened cloth before the plastic film is applied or the affected area may be briefly soaked 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. Flurandrenolide tape may be used alone as an occlusive dressing for small areas.

The 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. The occlusive dressing is usually left in place for 12-24 hours and therapy is repeated as needed. Some manufacturers state that the occlusive dressing may be left in place for 3-4 days at a time in resistant conditions, because theoretically the longer the occlusive dressing is left in place at one time, the more rapidly the dermatoses respond to topical corticosteroid therapy. However, 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. For example, the corticosteroid and an occlusive dressing may be used at night, and the topical corticosteroid 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.
