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.
Arginine is a semi-essential amino acid that serves as a substrate for nitric oxide (NO) synthesis via nitric oxide synthase (NOS), leading to vasodilation. It also stimulates growth hormone release and is involved in the urea cycle for ammonia detoxification.
For bronchial challenge testing: inhaled dose of 5 mg (one vial) via nebulizer, single administration.
10 mg intravenously over 1-2 minutes, once daily for 5 days, repeat course after 2-3 weeks if needed.

16.1 ± 8.5 minutes in healthy adults. Clinical context: Short half-life allows repeated provocative testing within 2–3 hours.
Terminal elimination half-life is 2-4 hours (mean 3 hours) in adults with normal renal function; prolonged to 8-18 hours in renal impairment.
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 (approximately 80-90% unchanged). Biliary/fecal elimination accounts for <5%.
