Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a corticosteroid that exerts anti-inflammatory effects by binding to glucocorticoid receptors, thereby inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production. Salmeterol is a long-acting beta2-adrenergic agonist (LABA) that stimulates adenyl cyclase, increasing cAMP levels, leading to bronchodilation and inhibition of mast cell mediator release.
Glucocorticoid receptor agonist; modulates gene expression to inhibit inflammatory mediators, vasoconstriction, and immunosuppression.
One inhalation (100 mcg fluticasone propionate and 50 mcg salmeterol) twice daily, approximately 12 hours apart, via oral inhalation.
Apply a thin layer to affected skin areas once or twice daily. Therapy should be discontinued when control is achieved; if no improvement is seen within 2 weeks, reassessment of diagnosis may be necessary.

Fluticasone propionate: terminal half-life approximately 8 hours (range 4-12 hours) after inhalation; clinical context: supports twice-daily dosing. Salmeterol: terminal half-life approximately 5.5 hours (range 3-10 hours) after inhalation; clinical context: supports twice-daily dosing.
2-4 hours (terminal elimination half-life); short half-life supports twice-daily dosing for maintenance of clinical effect.
Fluticasone propionate: primarily hepatic metabolism (CYP3A4), renal excretion of metabolites (~5% unchanged), fecal elimination of parent drug and metabolites. Salmeterol: primarily hepatic metabolism (CYP3A4), renal excretion of metabolites (about 25% of dose), fecal elimination.
Primarily hepatic metabolism; metabolites are excreted renally and fecally. Unchanged drug is negligible in urine. Route: renal (~60% as metabolites), fecal (~40% as metabolites).
