ARIDOL vs ARIDOL KIT
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.
Mannitol, a sugar alcohol, acts as an osmotic diuretic and osmotic agent. It increases plasma osmolality, drawing water from tissues into the bloodstream and enhancing urinary excretion. In the respiratory tract, it is used as a bronchial challenge agent to induce bronchoconstriction in patients with asthma by increasing airway osmolality and triggering mast cell mediator release.
For bronchial challenge testing: inhaled dose of 5 mg (one vial) via nebulizer, single administration.
Aridol (mannitol) is administered via inhalation as a dry powder for bronchial challenge testing. The standard adult dose is a single capsule (25 mg) inhaled using the Aridol inhaler device, with doses escalated as per protocol (e.g., 5, 10, 20, 40 mg cumulative) until a 15% fall in FEV1 is achieved or maximum cumulative dose of 160 mg is reached.

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 of mannitol is approximately 100 minutes (1.7 hours) in patients with normal renal function. This may be prolonged up to 36 hours in patients with renal impairment, necessitating dose adjustment.
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%).
Mannitol (the active ingredient in Aridol Kit) is primarily excreted unchanged in the urine via glomerular filtration, with approximately 80-90% of an intravenous dose eliminated within 24 hours. Less than 10% is metabolized in the liver, and negligible amounts are eliminated in feces or bile.
