Abstract
The compact, solid drug preparation, which contains N-acetylcysteine and/or S-(carboxymethyl)-L-cysteine, is suitable, despite small amounts of inactive ingredients, both for swallowing and for sucking or dissolving in water or an aqueous solution. The compactness of the drug preparation is guaranteed by a high proportion of active ingredients--more than 50% of the total weight--and by a suitable choice of a tableting adjuvant.
