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; induces phospholipase A2 inhibitory proteins (lipocortins), which suppress release of arachidonic acid and subsequent prostaglandin/leukotriene synthesis; also suppresses cytokine production and immune cell migration.
One inhalation (100 mcg fluticasone propionate and 50 mcg salmeterol) twice daily, approximately 12 hours apart, via oral inhalation.
Topical: Apply a thin layer to affected skin once or twice daily. Maximum use: 45 g/week.

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.
Terminal elimination half-life of approximately 2-3 hours; clinical context: duration of action may extend beyond half-life due to tissue binding.
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.
Renal (approximately 80% as metabolites, <5% unchanged), biliary/fecal (remainder).
