HC (HYDROCORTISONE) vs QNASL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone is a glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene transcription. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis; suppresses inflammatory cytokine production; and causes vasoconstriction and immunosuppression.
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.
Hydrocortisone 100-500 mg IV/IM every 2-6 hours as needed for acute adrenal insufficiency or severe inflammation. Maintenance: 20-30 mg/day PO divided every 8-12 hours.
1 to 2 sprays (80 mcg/spray) per nostril once daily; maximum 2 sprays/nostril/day.

1.5–2.5 hours (terminal half-life). In clinical context, the biological half-life (duration of HPA suppression) is longer (8–12 hours) due to tissue binding and active metabolites.
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: predominantly as conjugated metabolites and a small fraction of unchanged drug. Biliary/fecal: minor, <5%. Total renal clearance accounts for >95% of elimination.
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.
