Mechanism of Action

Duobrii (halobetasol propionate and tazarotene) is a combination of a corticosteroid and a retinoid. Halobetasol propionate is a high-potency corticosteroid that acts via glucocorticoid receptors to induce anti-inflammatory, antiproliferative, and immunosuppressive effects. Tazarotene is a retinoid prodrug that is converted to its active form, tazarotenic acid, which binds to retinoic acid receptors (RAR-β, RAR-γ) to modulate gene expression, thereby reducing keratinocyte proliferation and promoting differentiation.

WYNZORA (halobetasol propionate and tazarotene) is a fixed-dose combination of a corticosteroid (halobetasol) and a retinoid (tazarotene). Halobetasol acts by inducing phospholipase A2 inhibitory proteins, collectively called lipocortins, which control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes. Tazarotene is a retinoid prodrug that is converted to its active metabolite tazarotenic acid, which binds to retinoic acid receptors (RAR-γ, RAR-α, and RAR-β) and modulates gene expression, reducing epidermal proliferation and differentiation.
