A coating for masking or reducing the detectable presence of certain characteristic odor or odors, taste or tastes of pharmaceutical preparations, particularly valerian extracts, is described. The coating comprises from at least one to three coating compartments, in any combination or as a single-layer amalgam. The first coating compartment (4) preferably comprises a hydroxyalkyl cellulose and an anti-tackiness agent. The second coating compartment (6) preferably comprises a sugar and at least one anti-tackiness agent. The third coating compartment (8) preferably comprises a methacrylate copolymer, a hydroxyalkyl cellulose and an anti-tackiness agent. An option fourth coating compartment (10) may be applied as a cosmetic color coat, need not function as an odor-masking coat, and may be combined with one or more of the other three coating compartments. |
