蛋白质多肽类药物口服给药的研究进展

摘要：本文综述了近年来蛋白质多肽类药物口服给药的研究进展。蛋白质多肽类药物口服给药的研究对现代疾病的预防和治疗至关重要。由于蛋白质多肽类药物在消化道内易被破坏，市售蛋白质多肽类药物主要以注射为主。但是频繁的注射会给病患带来极大的痛苦，因此口服成为了研究的焦点。大量研究证明，运用结构修饰、应用吸收促进剂、酶抑制剂、制备新型载药等方法，可以提高蛋白质多肽类药物在肠道内的稳定性，并提高其口服生物利用度，使蛋白质多肽类药物口服给药展现出更美好的前景。

The research of protein peptide drugs for oral administration

Abstract: This paper reviews recent oral administration of peptide drugs research. Proteinprptide drugs for oral administration study of modern disease prevention and treatment is essential. As the protein peptide drugs susceptible to damage in the digestive tract, commercially available protein-based peptide drugs mainly injected. However, patients with frequent injections will bring great pain, so oral as a research focus. Numberous studies have demonstrated the use of structural modification, the application of absorption enhancers, enzyme inhibitors, such as preparation of new drug delivery methods, the protein peptide drugs increase the stability in the intestine and increase its oral bioavailability, protein peptide drugs oral administration show a more promising future.
