Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednisolone is a glucocorticoid receptor agonist that binds to the intracellular glucocorticoid receptor, leading to modulation of gene expression. It suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production (e.g., IL-1, IL-6, TNF-alpha). It also suppresses immune responses by reducing lymphocyte proliferation and activity.
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.
Oral: 5-60 mg/day as a single dose or divided doses; adjust based on condition and response.
1 to 2 sprays (80 mcg/spray) per nostril once daily; maximum 2 sprays/nostril/day.

2.5–3.5 hours (terminal) in children; clinical context: requires multiple daily doses for sustained effect.
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: ~80% as metabolites (mainly glucuronides and sulfates) and <5% unchanged; fecal: ~15%.
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.
