HYDROCORTISONE AND ACETIC ACID vs QNASL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone is a corticosteroid that binds to the glucocorticoid receptor, leading to increased lipocortin synthesis, inhibition of phospholipase A2, decreased arachidonic acid release, and reduced prostaglandin and leukotriene production; it also suppresses cytokine expression and immune cell migration. Acetic acid is a weak acid that lowers local pH, inhibiting bacterial and fungal growth and disrupting microbial cell membranes.
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.
Instill 5 drops into affected ear(s) twice daily for 7-10 days; or as directed by physician.
1 to 2 sprays (80 mcg/spray) per nostril once daily; maximum 2 sprays/nostril/day.

Plasma t1/2: 1.5-2 hours; biological t1/2: 8-12 hours (based on HPA axis suppression).
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: ~60-70% as metabolites; biliary/fecal: ~10-15%; unchanged drug: <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.
