Research progress in polymeric microspheres in oral drug delivery system / 国际生物医学工程杂志

ABSTRACT

As a drug carrier, polymer microspheres have been widely used in oral drug delivery systems, which can achieve the purposes of protecting drug stability, slowing drug release, enhancing immunity, and improving drug absorption. The polymer materials used in the preparation of microspheres can be derived from natural substances, such as cellulose, polysaccharides, and proteins. These materials can also be derived from synthetic polymer substances, such as polycaprolactone and polylactic acid. In this paper, the role of microspheres in oral drug delivery and the types of oral microspheres were reviewed to provide references for in-depth research and development of oral microspheres.
