Controlled Release

Many pharmaceutical formulations require time-dependent release of the active pharmaceutical ingredient (API).  The order and time profile of the API release is formulation specific and optimized towards the required therapeutic objectives.  ABITEC manufactures and supplies a range of products that can be readily employed in the formulation of controlled-release dosage forms.

ABITEC's partially hydrogenated vegetable oils are refined, bleached, and deodorized. Multi-functional Sterotex is utilized as an encapsulating coating or as a highly functional matrix material in applications such as controlled or modified release, active barrier protection, and taste masking.

Capmul functional lipids act as solubilizers and emulsifiers in oral delivery systems. Capmul ingredients are recognized as the ideal starting point when formulating poorly water soluble and poorly permeable molecules. Lipid based nutraceutical delivery systems may be formulated as liquid or semi-solid formulations for oral dosage forms.

Featuring Capmul GDB EP/NF, our unique lipid excipient is ideal for controlled release applications because it is a solubilizer, emulsifier and has a high melt point.
