The FDA (2002) stated this in a review document pertaining to the formulation change: "The current tablets are sugar coated. The tablet core is sealed with a coat of pharmaceutical glaze (shellac) prior to applying the sugar coating."
As I mentioned in the post that I linked to earlier, pharmaceutical glaze, or shellac, is an enteric coating material. It is water-insoluble at low pH levels and water-soluble at high pH levels (Pearnchob et al., 2004)
