ADVAIR HFA vs CORTENEMA
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 the glucocorticoid receptor, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, decrease cytokine production, and suppress inflammatory cell migration and activation in the colonic mucosa.
2 inhalations (fluticasone 230 mcg/salmeterol 21 mcg per inhalation) twice daily, approximately 12 hours apart, via oral inhalation. Maximum: 2 inhalations twice daily.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.

Fluticasone propionate: 7.8 hours (inhalation), prolonged in hepatic impairment. Salmeterol: 5.5 hours.
1.8-3.5 hours (plasma); due to rectal administration and low systemic absorption, clinical effects persist longer than plasma levels suggest
Fluticasone propionate: Renal <5%, fecal (primarily as metabolites) ~90%. Salmeterol: Renal 25% (as metabolites), fecal 60%.
Primarily hepatic metabolism with renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
