About halobetasol foam

Halobetasol propionate topical foam is a corticosteroid indicated for the topical treatment of plaque psoriasis in patients eighteen years of age and older. Halobetasol foam was evaluated for the treatment of moderate to severe plaque psoriasis in two multicentre, randomised, double-blind, vehicle-controlled studies. These studies were conducted in 560 subjects with plaque psoriasis involving between 2% and 12% body surface area. A foam vehicle can have many benefits including being aqueous-based, absorbed quickly without residue or greasiness and easy to apply to both hair-bearing and non-hair bearing skin.

Important Safety Information                              

Halobetasol propionate foam is a topical corticosteroid that has been shown to suppress the hypothalamic-pituitary-adrenal (HPA) axis.  Systemic effects of topical corticosteroids may include reversible HPA axis suppression, with the potential for glucocorticosteroid insufficiency. This may occur during treatment or upon withdrawal of treatment of the topical corticosteroid. The potential for hypothalamic-pituitary adrenal (HPA) suppression with halobetasol propionate foam was evaluated in a study of 25 adult subjects with moderate to severe plaque psoriasis involving ≥15% of their body surface area. halobetasol propionate foam produced laboratory evidence of HPA axis suppression when used twice daily for two weeks in 6 out of 25 (24%) adult subjects with plaque psoriasis. Recovery of HPA axis function was generally prompt with the discontinuation of treatment.

Systemic effects of topical corticosteroids may also include Cushing’s syndrome, hyperglycemia, and glucosuria. Use of more than one corticosteroid-containing product at the same time may increase the total systemic exposure to topical corticosteroids.

Local adverse reactions from topical corticosteroids may include atrophy, striae, telangiectasias, burning, itching, irritation, dryness, folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, and miliaria.  These may be more likely to occur with occlusive use, prolonged use, or use of higher potency corticosteroids, including halobetasol propionate foam. Some local adverse reactions may be irreversible.  Use of topical corticosteroids may increase the risk of posterior subcapsular cataracts and glaucoma.

About Plaque Psoriasis

Psoriasis is a chronic (life-long) skin condition. It occurs when the immune system “speeds up” the growth cycle of skin cells. A normal skin cell matures and falls off the body in about a month.  For people with plaque psoriasis, it can take only three or four days for new skin cells to develop. Instead of falling off, the cells remain on the skin and form thickened patches (lesions or plaques). While plaque psoriasis is a chronic condition, many patients experience times when their symptoms improve or worsen.

Plaque psoriasis is the most common form of psoriasis. It typically causes raised, red lesions covered with silvery white scales.  Plaque psoriasis can occur on any part of the body, but most commonly on the scalp, knees, elbows, and torso.
