Abstract (en)

[origin: WO9428878A1] Improved proteinoid carriers and methods for their preparation and use as oral delivery systems for pharmaceutical agents are described. The proteinoid carriers 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 carriers are prepared from proteinoids having between 2 and 20 amino acids and having a molecular weight of between about 250 and 2400 daltons.
