Abstract
The delivery of biopharmaceuticals is not optimal yet and various systems are being investigated to improve the bioavailability of these drugs. The Pheroid™ drug delivery system, which consists mainly of essential fatty acids, has proven successful in the nasal delivery of vaccines and peptide drugs. Pheroid™ technology can be used to manufacture mainly two types of structures, Pheroid™ vesicles that are small vesicular structures and Pheroid™ microsponges, that have a sponge-like membrane. Both these formulations have been formulated with vaccines and peptide drugs and evaluated in various in vivo studies. Results show that both Pheroid™ vesicles and Pheroid™ microsponges are effective in increasing the bioavailability of peptide drugs, but Pheroid™ vesicles are more effective. The differences between the Pheroid™ vesicles and Pheroid™ microsponges have been attributed to the lipid bilayer composition and the size of the structures within the colloid.
