FLOVENT DISKUS 50 vs HYDROCORTISONE AND ACETIC ACID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; anti-inflammatory transcription factor modulation; inhibits phospholipase A2, reduces arachidonic acid release, decreases prostaglandin and leukotriene synthesis; suppresses cytokine production and inflammatory cell migration.
Hydrocortisone is a corticosteroid that binds to the glucocorticoid receptor, leading to increased lipocortin synthesis, inhibition of phospholipase A2, decreased arachidonic acid release, and reduced prostaglandin and leukotriene production; it also suppresses cytokine expression and immune cell migration. Acetic acid is a weak acid that lowers local pH, inhibiting bacterial and fungal growth and disrupting microbial cell membranes.
1 inhalation (50 mcg) twice daily, administered via oral inhalation.
Instill 5 drops into affected ear(s) twice daily for 7-10 days; or as directed by physician.

Terminal elimination half-life is approximately 14-17.5 hours; this supports once- or twice-daily dosing in asthma maintenance.
Plasma t1/2: 1.5-2 hours; biological t1/2: 8-12 hours (based on HPA axis suppression).
Primarily fecal (87-90%) after hepatic metabolism; renal excretion accounts for <5% as unchanged drug and metabolites.
Renal: ~60-70% as metabolites; biliary/fecal: ~10-15%; unchanged drug: <5%.
