FERNISONE vs HYDELTRA-TBA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FERNISONE is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, decreased prostaglandin and leukotriene synthesis, and suppression of inflammatory mediators.
Prednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, modulating gene transcription to suppress inflammation, immune response, and adrenal function.
40 mg orally once daily
20-40 mg intramuscularly every 3 weeks; for intra-articular use: 20-40 mg per large joint, 10-20 mg per medium joint, 4-10 mg per small joint.

Terminal elimination half-life: 18-24 hours in healthy adults. In elderly (age >65), half-life increases to 30-36 hours due to reduced renal function. In moderate renal impairment (CrCl 30-60 mL/min), half-life extends to 40-48 hours. Clinical context: requires dose adjustment in renal impairment; steady-state reached in 3-5 days.
Plasma t1/2 ~2.5-3.5 hours. Duration of adrenal suppression may persist for 24-48 hours.
Renal excretion of unchanged drug and metabolites: ~60% (30% unchanged, 30% metabolites). Biliary/fecal elimination: ~35% (primarily as metabolites). Minor metabolic clearance via CYP3A4. About 5% eliminated in sweat and saliva.
Primarily renal (80-90% as inactive metabolites and unchanged drug). Biliary excretion accounts for <5%.
