FLOVENT HFA vs SERVISONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a synthetic corticosteroid that binds to glucocorticoid receptors, increasing the synthesis of lipocortins, which inhibit phospholipase A2, thereby reducing arachidonic acid release and decreasing prostaglandin and leukotriene production. It also suppresses inflammatory cell migration and cytokine release, leading to reduced airway inflammation and hyperreactivity.
SERVISONE is a corticosteroid that exerts anti-inflammatory and immunosuppressive effects by binding to glucocorticoid receptors, modulating gene transcription, and inhibiting phospholipase A2, thereby reducing prostaglandin and leukotriene synthesis.
Adult: 88-880 mcg twice daily via oral inhalation; typical starting dose: 88 mcg twice daily for patients previously on bronchodilators alone, 220 mcg twice daily for patients on inhaled corticosteroids.
10-20 mg orally once daily in the morning; higher doses up to 40 mg daily for severe cases.

Terminal elimination half-life is approximately 7.8 hours (range 6.5-10.6 hours) after inhalation, supporting twice-daily dosing.
Terminal elimination half-life is 3-4 hours. Clinically, this supports twice-daily dosing for sustained effect.
Primarily fecal (approximately 60-80%) after biliary elimination, with renal excretion accounting for <5% as unchanged drug and metabolites.
Renal (70-80% as metabolites, 5-10% unchanged); fecal/biliary (15-20%)
