经鼻给药的机遇与挑战

Opportunities and Challenges of Nasal Drug Delivery

作为一种非侵入给药方式,鼻腔给药具有快速起效、使用方便、依从性高、无首过效应、不良反应较小、黏膜免疫等诸多优点,且提供了鼻脑递送途径,鼻用制剂日益成为研发热点,以着力解决未被满足的临床需求。但是,因鼻腔结构和生理学上的特殊性,鼻用制剂的开发和评价还存在诸多挑战。

As a non-invasive drug delivery method,nasal drug delivery has many advantages,such as rapid onset,easy use,high compliance,no first pass effect,fewer adverse reactions,mucosal immunity,and provides a new convenient route to deliver drugs to the brain through nose-to-brain delivery.Nasal formulations are increasingly becoming a research and development hotspot,focusing on addressing unmet clinical needs.However,due to the special structure and physiology of the nasal cavity,there are still many challenges in the development and evaluation of nasal preparations.
