COR-OTICIN vs WYNZORA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
COR-OTICIN is a combination product containing hydrocortisone (a corticosteroid with anti-inflammatory and immunosuppressive properties) and neomycin (an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit) and polymyxin B (a polymyxin antibiotic that disrupts bacterial cell membrane permeability).
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.
