These include: • Cost. The used films protect the drug substance against denaturation by stomach acid and/or support a delayed (modified) release of the drug substance ("retard effect"). Waterproofing . conventional tablets (1) Disadvantages of direct compression (1) Disadvantages of dry granulation (1) Effervescent tablets (1) Environmental moisture (1) Examples of mixers (1) Fillers (1) 3. Also called as gastro-resistant, these tablets are resistant to acidic gastric juices.
