Oral dosage forms: controls release by remaining intact in gastric acid and dissolving at higher intestinal pH
Enteric coating of tablets
Capsules and granules: protection from stomach acid for acid-sensitive active pharmaceutical ingredients
Sustained-release pellet systems: coating thickness and polymer concentration determine dissolution lag time
Film-coating solutions: incorporated with plasticizers for coating uniformity
Controlled-release granulation: binder and matrix former
