Administração oral de peptídeos e proteínas: II. Aplicação de métodos de microencapsulação

Abstract

Choosing an appropriate microencapsulation method to improve the oral bioavailability of peptide drugs depends on the drug physico-chemical properties, operation conditions and selected polymers. Microencapsulation techniques and its application in peptide and protein oral delivery are reviewed. Natural polymers and techniques involving no harsh conditions such as extreme pH, high temperature and solvents use are the most important when encapsulating peptide drugs.
