Abstract
Improved proteinoid microspheres and methods for their preparation and use as oral delivery systems for pharmaceutical agents are described. The proteinoid microspheres are soluble within selected pH ranges within the gastrointestinal tract and display enhanced stability towards at least one of photolysis or decomposition over time. The proteinoid microspheres are prepared from proteinoids having between 2 and 8 amino acids and having a molecular weight of about 1000 daltons.
