摘要:
The present invention is directed to liquid coating compositions and dosage forms having a continuous shell portion of a first composition and at least one discontinuous shell portion that is compositionally different located within the continuous shell portion. The present invention also provides a process for preparing a dosage form, which comprises coating a core with a continuous shell portion having a first composition and at least one discontinuous shell portion that is compositionally different located within the continuous portion, and then cooling the coated core. The coating compositions are particularly suited for forming shell coatings on solid pharmaceutical dosage forms.
