Encapsulation of active ingredients is intended to impart desired functionality on a specific pharmaceutical dosage form. The unit operation involves the inclusion of an active within a multi-particulate designed to provide a specific functionality or multiple functionalities, such as sustained or delayed release. ABITEC manufactures a series of functional lipids that are readily employed in encapsulation unit operations.


Sterotex hydrogentated vegetable fats are an excellent ingredient for developing encapsulated multi-particulates as well as matrix mulit-particulates by means of congealing, hot-melt spraying, or micro-encapsulation processing. Sterotex grades can be employed as encapsulating coatings or matrix materials in applications such as sustained-release, abuse deterrence, moisture barrier, and taste masking. Sterotex can also serve as a uniform, encapsulating substrate coat for the further deposition of other functional coatings.
