CHLOROMYCETIN HYDROCORTISONE vs ORASONE
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.
Orasone (prednisone) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines, immune response, and adrenal function.
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.
Adults: 5-60 mg orally once daily or divided twice daily; typical starting dose 5-40 mg/day. Route: oral. Frequency: once daily or every 12 hours.

moderateDiflorasone + Gatifloxacin
"The risk or severity of adverse effects can be increased when Diflorasone is combined with Gatifloxacin."

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 half-life of 3-4 hours for prednisolone (active metabolite of ORASONE); clinically, duration of HPA-axis suppression is more relevant (12-36 hours) with longer effects at higher doses.
Renal: ~80-90% of chloramphenicol as inactive metabolites (glucuronide conjugate) and 5-10% unchanged. Biliary: <3% of unchanged drug. Fecal: minimal.
Primarily renal: ~80% as 17-keto metabolites and unchanged drug; biliary/fecal excretion accounts for <10%.
