PREDNISOLONE vs QNASL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednisolone is a glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines, inhibition of phospholipase A2, and reduction of prostaglandin and leukotriene synthesis.
Beclomethasone dipropionate is a corticosteroid with anti-inflammatory activity. It binds to glucocorticoid receptors, inhibiting inflammatory mediators such as prostaglandins and leukotrienes, and reducing nasal inflammation.
Initial adult dose: 5-60 mg orally, intramuscularly, or intravenously daily, divided into 2-4 doses; maintenance: 2.5-15 mg daily.
1 to 2 sprays (80 mcg/spray) per nostril once daily; maximum 2 sprays/nostril/day.

Terminal half-life: 2.1-3.5 hours in adults; prolonged in hepatic impairment (up to 12 hours) or with concurrent estrogen use.
The terminal elimination half-life is approximately 8-10 hours in healthy adults, supporting twice-daily administration for systemic effects; however, intranasal administration results in minimal systemic absorption, and local half-life in nasal tissues is not well characterized.
Renal (primarily as glucuronide and sulfate conjugates; <20% as unchanged prednisolone); biliary/fecal (minor, <5%).
The majority of a dose (approximately 40-50%) is excreted in feces as unchanged drug and metabolites, with about 10-15% excreted in urine as metabolites. Biliary excretion is the primary route of elimination.
