DELAYED-RELEASE TABLETS The place the drug can be wrecked or inactivated from the gastric juice or where it might irritate the gastric mucosa, the usage of “enteric” coatings is indicated.
Simple COATED TABLETS Classically, tablets have already been coated with sugar applied from aqueous suspensions containing insoluble powders for instance starch, calcium carbonate, talc, or titanium dioxide, suspended through acacia or gelatin.
