Pharmacology
Brodalumab is a human monoclonal IgG2 antibody that selectively binds to IL-17RA and inhibits its interactions with IL-17 family cytokines (IL-17A, IL-17F, IL-17C, IL-17A/F heterodimer, IL-25), thereby blocking IL-17 cytokine-induced pro-inflammatory responses.
Combination of halobetasol propionate, a synthetic corticosteroid that modulates cellular signaling, immune function, and inflammation, and tazarotene, a retinoid prodrug converted by esterase hydrolysis to tazarotenic acid, which binds RAR-beta and RAR-gamma receptors to modify gene expression; precise mechanisms in plaque psoriasis are unknown.
