Fluticasone
Fluticasone is a steroid Fluticasone inhalation is used to prevent asthma attacks. Fluticasone inhalation will not treat an asthma attack that has already begun. Flovent HFA and Flovent Diskus are sometimes used together with an oral (taken by mouth) steroid medicine. Flovent brands of fluticasone inhalation are for use in adults and children who are at least 4 years old. The Arnuity Ellipta brand is for adults and children who are at least 12 years old.
Mechanism of effect
Fluticasone belongs to a group of corticosteroids which utilizes a fluorocarbothioate ester linkage at the 17 carbon position; extremely potent vasoconstrictive and anti-inflammatory activity. The effectiveness of inhaled fluticasone is due to its direct local effect.
Pharmacodynamic
Fluticasone is an extremely potent vasoconstrictor and anti-inflammatory agent. Its effectiveness in inhaled forms is due to its direct local effect.
Pharmacokinetics
Absorbed systemically (Flovent Diskus: ~18%) primarily via lungs, minimal GI absorption (<1%) due to presystemic metabolism. Metabolism:Hepatic via CYP3A4. Excretion:Feces (as parent drug and metabolites); urine (<5% as metabolites). Onset of Action:Maximal benefit may take 1 to 2 weeks or longer. Time to Peak:0.5 to 1 hour. Half-Life Elimination:IV: ~8 hours; Oral inhalation (plasma elimination phase following repeat dosing): 24 hours. Protein Binding:>99%.

1-may contain lactose; very rare anaphylactic reactions have been reported in patients with severe milk protein allergy. 2- Adrenal suppression: May cause hypercorticism or suppression of hypothalamic-pituitary-adrenal (HPA) axis in sensitive patients. HPA axis suppression may lead to adrenal crisis.
Points of recommendation
Bronchospasm: May occur with wheezing after inhalation; if this occurs, stop steroid and treat with a fast-acting bronchodilator.
