title: The effect of Mucodyne on nasal clearance in healthy adults.
abstract: A randomized double-blind cross-over trial in healthy young adults compared the effect of S-carboxymethylcysteine (2.25 g per day for 7 days) against placebo on nasal mucociliary clearance. The clearance rate of a radio-labelled aqueous test spray was measured by gamma scintigraphy. Analysis of the data revealed no significant effect of the drug compared to placebo.
