Tác dụng
Description: Mechanism of Action: Fluticasone belongs to a group of corticosteroid which utilises a fluorocarbothioate ester linkage at the 17 carbon position. It has a potent anti-inflammatory and vasoconstrictive activity. Topical fluticasone exhibits its anti-inflammatory, antipruritic and vasoconstrictive properties by depressing the formation, release and activity of endogenous chemical mediators of inflammation through the induction of phospholipase A2 inhibitory proteins and consequent inhibition of arachidonic acid release. Onset: Oral inhalation: 1-2 weeks or longer. Pharmacokinetics: Absorption: Absorbed systemically primarily via lungs. Bioavailability: 13.9% (oral inhalation); <2% (nasal). Time to peak plasma concentration: 0.5-1 hour (oral inhalation). Distribution: Volume of distribution: 4.2 L/kg (fluticasone propionate); 608 L (fluticasone furoate). Plasma protein binding: >99%. Metabolism: Undergoes extensive first-pass metabolism, converted to 17β-carboxylic acid by CYP3A4 isoenzyme. Excretion: Faeces (as unchanged drug and metabolites); urine (<5% as metabolites).
