ARIDOL vs PORCINE SECRETIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aridol (mannitol) is an osmotic agent that, when inhaled, increases airway osmolarity, leading to release of mediators from mast cells and eosinophils, causing bronchoconstriction in susceptible individuals. It is used as a bronchial challenge test to assess airway hyperresponsiveness.
Stimulates exocrine pancreatic secretion by acting on secretin receptors on pancreatic ductal cells, increasing bicarbonate and water secretion. Also stimulates bile and gastric acid secretion.
For bronchial challenge testing: inhaled dose of 5 mg (one vial) via nebulizer, single administration.
0.2 mcg/kg intravenous bolus over 1 minute, maximum 20 mcg.

16.1 ± 8.5 minutes in healthy adults. Clinical context: Short half-life allows repeated provocative testing within 2–3 hours.
The terminal elimination half-life is approximately 4-6 minutes, reflecting rapid degradation by plasma proteases; this short half-life limits its systemic duration of action and necessitates continuous infusion for sustained secretory testing.
Primarily renal excretion of unchanged mannitol. Approximately 80% of the administered dose is excreted unchanged in urine within 12 hours; minor biliary/fecal elimination (<5%).
Primarily renal, with over 90% of the administered dose eliminated via glomerular filtration and tubular reabsorption; fecal and biliary excretion are negligible.
