Betamethasone

Betamethasone Dipropionate Ointment Medication Description

Betamethasone dipropionate is classified as a high-potency corticosteroid designed for short-term treatment of corticosteroid-responsive dermatoses. It exerts anti-inflammatory, antipruritic, and vasoconstrictive effects by binding to glucocorticoid receptors in skin cells, altering gene expression to suppress inflammatory mediators such as prostaglandins and leukotrienes. This mechanism reduces swelling, redness, and itching associated with conditions like plaque psoriasis, atopic dermatitis, and allergic contact dermatitis. Treatment duration is typically limited to two weeks, with a maximum of 50 grams per week, to minimize systemic absorption and prevent hypothalamic-pituitary-adrenal (HPA) axis suppression. Occlusive dressings should not be used unless specifically instructed, as they significantly increase absorption. Clinical monitoring is essential for patients using large amounts or prolonged therapy, especially in older adults, due to increased risk of systemic effects.
