1 Products E1 and E6 do not list a main enteric coating agent. Later labels for product E1 (© 2013–© 2016) omitted the phrase “aqueous coating solution” and included sodium alginate, a common enteric coating agent; however, the newer tablets have a different appearance (less shine) than those used in this study, indicating a change in the coating formulation. 2 Known enteric coating agents. Stearic acid has additional purposes in tablet formulation. Only product E4 specifically stated which ingredients were used for the enteric coating.
