ADVAIR HFA vs TRIAMCINOLONE ACETONIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ADVAIR HFA is a combination of fluticasone propionate, a corticosteroid that reduces inflammation by inhibiting multiple inflammatory cell types and mediators, and salmeterol, a long-acting beta2-adrenergic agonist that relaxes bronchial smooth muscle by stimulating adenyl cyclase and increasing cAMP levels.
Corticosteroid that binds to glucocorticoid receptors, leading to inhibition of phospholipase A2, decreased prostaglandin and leukotriene synthesis, and suppression of inflammatory cytokines.
2 inhalations (fluticasone 230 mcg/salmeterol 21 mcg per inhalation) twice daily, approximately 12 hours apart, via oral inhalation. Maximum: 2 inhalations twice daily.
Intramuscular: 40-80 mg every 4 weeks. Intra-articular: 5-40 mg depending on joint size. Topical: Apply thin film to affected area 2-4 times daily.

Fluticasone propionate: 7.8 hours (inhalation), prolonged in hepatic impairment. Salmeterol: 5.5 hours.
Terminal elimination half-life approximately 2-5 hours; but suppression of adrenal function (HPA axis) can persist for 7-30 days depending on dose and duration.
Fluticasone propionate: Renal <5%, fecal (primarily as metabolites) ~90%. Salmeterol: Renal 25% (as metabolites), fecal 60%.
Renal (primarily as metabolites, <5% unchanged); biliary/fecal (minor).
