Used in pharmaceutical formulations as a coating agent for tablets and capsules, providing controlled or delayed release of active ingredients. It is especially effective in enteric coatings, protecting drugs from the acidic environment of the stomach and releasing them in the intestine. Its film-forming properties ensure mechanical strength and stability of the dosage form. Also utilized in multiparticulate systems like pellets and granules where pH-dependent release is required. Commonly applied in oral solid dosage forms for improved bioavailability and reduced gastric irritation.
