In our study, two independent comparisons of plain, 2% hypertonic Saline with the Active, isotonic saline showed consistent trends in favor of the Active solution containing added antimicrobial ingredients.
Though 2% to 5% hypertonic saline solutions may be superior to isotonic saline in objective ways, they may be more likely to cause burning or stinging, and thus be less used by sensitive participants.

The 3-mL plastic syringes (Becton Dickinson) were preloaded with 10 mL/L of either isotonic saline or porcine intestine-derived sodium heparin (Elkins-Sinn, Cherry Hill, NJ) diluted in saline and tested at 300 IU/L final concentration.
To isotonic saline or urine (10 mL) we added 276 nmol/L corticosterone (Sigma Chemicals) as internal standard (IS) and various concentrations (138-4416 nmol/L) of cortisol (hydrocortisone; Sigma Chemicals) and its conjugated metabolites (purchased from Steraloids): 4-pregnen-11[beta],17,21-triol-3,20-dione-21-acetate (cortisol acetate), -21-sulfate, and -21-glucosiduronate.
