Fluticasone furoate comes in a nasal spray, as an aqueous suspension of micronized fluticasone furoate for topical administration to the nasal mucosa by means of a metering, atomizing spray pump.
Fluticasone furonate displays great potency in inhibiting tumor necrosis factor synthesis and action. Fluticasone furonate is also potent in preventing damage to cultured human lung epithelial cells by different stimulus.
Fluticasone furonate is 99.4% bound to plasma protein in vitro and other research indicated extensive first-pass metabolism of the absorbed drug. Protein binding is highly relevant because only the unbound free drug can exert an effect at the receptor site. Clearance of Fluticasone furonate is primarily by hydrolysis in the liver by the cytochrome P450 isozyme (CYP) 3A4 that converts the drug to the 17β-carboxylic acid metabolite (M10), which displays low glucocorticoid receptor agonist potency. Fluticasone furonate is excreted mainly in the feces, with only minor amounts in the urine.
