The corticosteroids constitute a class of primarily synthetic steroids used topically as an anti-inflammatory and antipruritic agent. Chemically halobetasol propionate is 21-chloro-6α, 9-difluoro-11β, 17-dihydroxy-16β-methylpregna-1, 4-diene-3-20-dione, 17-propionate, C 25 H 31 CIF 2 O 5 . It has the following structural formula: Halobetasol propionate has the molecular weight of 485. It is a white crystalline powder insoluble in water. Each gram of halobetasol propionate cream, 0.05% contains 0.5 mg of halobetasol propionate in a cream base of cetyl alcohol, diazolidinyl urea, glycerin, isopropyl isostearate, isopropyl palmitate, methylchloroisothiazolinone, (and) methylisothiazolinone, steareth-21 and water.

Halobetasol propionate cream, 0.05% is a super-high potency corticosteroid indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses. Treatment beyond two consecutive weeks is not recommended, and the total dosage should not exceed 50 g/week because of the potential for the drug to suppress the hypothalamic-pituitary-adrenal (HPA) axis. Use in children under 12 years of age is not recommended. As with other highly active corticosteroid, therapy should be discontinued when control has been achieved. If no improvement is seen within 2 weeks, reassessment of the diagnosis may be necessary.
