CHLOROMYCETIN HYDROCORTISONE vs FLOVENT DISKUS 50
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chloromycetin (chloramphenicol) is a bacteriostatic antibiotic that inhibits protein synthesis by binding to the 50S ribosomal subunit, preventing peptide bond formation. Hydrocortisone is a corticosteroid that suppresses inflammation by inhibiting phospholipase A2 and reducing prostaglandin and leukotriene synthesis.
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.
Apply 1-2 drops or a small amount (approximately 0.5 cm ribbon) into the affected eye(s) every 3-4 hours, or more frequently as needed. For severe infections, may be used every 2 hours. Not to exceed 6 times daily. Otic: Instill 3-4 drops into the affected ear(s) 2-3 times daily.
1 inhalation (50 mcg) twice daily, administered via oral inhalation.

Chloramphenicol: 1.5-4 hours in adults with normal hepatic function; prolonged to 3-7 hours in neonates and up to 15 hours in severe liver disease. Hydrocortisone: 1-2 hours.
Terminal elimination half-life is approximately 14-17.5 hours; this supports once- or twice-daily dosing in asthma maintenance.
Renal: ~80-90% of chloramphenicol as inactive metabolites (glucuronide conjugate) and 5-10% unchanged. Biliary: <3% of unchanged drug. Fecal: minimal.
Primarily fecal (87-90%) after hepatic metabolism; renal excretion accounts for <5% as unchanged drug and metabolites.
