FLOVENT DISKUS 250 vs PENECORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a corticosteroid with potent anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines, reduction of eosinophil recruitment, and suppression of airway hyperresponsiveness.
PENECORT is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation, immune responses, and adrenal function.
250 mcg inhaled orally via DISKUS twice daily (500 mcg total daily dose).
2.5-5 mg orally once daily; maximum 10 mg/day. Intramuscular: 20-40 mg every 2-4 weeks.

Approximately 10-12 hours (terminal elimination half-life in asthmatics).
Terminal elimination half-life: 3-4 hours in adults; prolonged in hepatic impairment (up to 8 hours).
Renal (approximately 5% as unchanged drug); fecal (majority as metabolites and unabsorbed drug).
Renal: 60-70% as metabolites, 5-10% unchanged; Biliary/fecal: 20-30% as metabolites.
