Fluticasone furoate (Avamys) is a synthetic trifluorinated corticosteroid derived from fluticasone with a Kd of 0.3 nM. Fluticasone furoate has potent anti-inflammatory, anti-asthmatic activity, and low systemic exposure. Fluticasone furoate can be used as a nasal spray for studies about allergic rhinitis treatment.

Corticosteroid:0.3 nM (Kd)

Fluticasone furoate displays great potency in inhibiting tumor necrosis factor synthesis and action. Fluticasone furoate prevents damage to cultured human lung epithelial cells by different stimuli[2].

Fluticasone furonate is excreted mainly in the feces, with only minor amounts in the urine. Fluticasone furonate is 99.4% bound to plasma protein in vitro. Clearance of Fluticasone furonate is primarily by hydrolysis in the liver by the cytochrome P450 isozyme CYP3A4 that converts the drug to the 17β-carboxylic acid metabolite, which displays low glucocorticoid receptor agonist potency[2].
