Oral Macromolecule Delivery


Currently, due to permeability, stability, and delivery challenges, the dosing of macromolecules has been traditionally delivered in an intravenous form. Intravenous drug delivery, while able to provide an optimal pharmacokinetic therapeutic profile, presents challenges such as ease of use, dosing frequency, regulatory challenges, costs, and compliance.

Catalent OptiGel® Bio technology incorporates a proprietary technology that may overcome the traditional hurdles by enhancing permeability and enabling a targeted delivery through enteric coating. Catalent’s development expertise can rapidly identify an optimal Oral formulation enabling the traditional benefits of an oral softgel formulation and subsequent commercialization.
