Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Triacetin is a triester of glycerol and acetic acid. Its exact mechanism of action is not fully understood, but it exhibits antifungal activity by disrupting fungal cell membrane integrity and inhibiting fungal growth.
1 to 2 sprays (80 mcg/spray) per nostril once daily; maximum 2 sprays/nostril/day.
0.5-1 mg orally three times daily; maximum dose 4 mg/day.

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.
Terminal elimination half-life is approximately 3.5–4 hours in adults with normal renal function; may be prolonged (up to 6–8 hours) in patients with hepatic impairment.
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.
Renal, unchanged drug: <1% of dose; metabolites: approximately 20% in urine, remainder in feces via biliary elimination.
