Drug-Drug:
Aerosol for Oral Inhalation
12 yr): No prior treatment with inhaled corticosteroid 88 mcg twice daily initially, may ↑ dose in 2 wk if not adequately responding (max dose = 880 mcg twice daily).Powder for Oral Inhalation
12 yr): No prior treatment with inhaled corticosteroid Propionate (Flovent Diskus): 100 mcg twice daily initially, may ↑ dose in 2 wk if not adequately responding (max dose = 1,000 mcg twice daily); Propionate (Armonair Respiclick): 55 mcg twice daily initially, may ↑ dose in 2 wk if not adequately responding (max dose = 232 mcg twice daily); Furoate: 100 mcg once daily, may ↑ dose in 2 wk to 200 mcg once daily if not adequately responding (max dose = 200 mcg once daily); Prior treatment with inhaled corticosteroid Propionate (Armonair Respiclick): 55232 mcg twice daily (starting dose should be based on dose of previous inhaled corticosteroid and disease severity) (max dose = 232 mcg twice daily); Furoate: 100200 mcg once daily (max dose = 200 mcg once daily).Absorption: <1% (aerosol), 814% (powder). Action is primarily local after inhalation.
Distribution: 1025% of inhaled corticosteroids is deposited in the airways if a spacer device is not used. With the use of a spacer, a greater percentage may reach the respiratory tract. Crosses the placenta and enters breast milk in small amounts.
Protein Binding: 9199%.
Metabolism/Excretion: Metabolized by the liver primarily by the CYP3A4 isoenzyme after absorption from lungs; <5% excreted in urine; remainder excreted in feces.
Half-life: 7.8 hr (propionate); 24 hr (furoate).
