Particles, compositions, and methods that aid particle transport in mucus are provided. The particles, compositions, and methods may be used, in some instances, for ophthalmic and/or other applications. In some embodiments, the compositions and methods may involve modifying the surface coatings of particles, such as particles of pharmaceutical agents that have a low aqueous solubility. Such compositions and methods can be used to achieve efficient transport of particles of pharmaceutical agents though mucus barriers in the body for a wide spectrum of applications, including drug delivery, imaging, and diagnostic applications. In certain embodiments, a pharmaceutical composition including such particles is well-suited for ophthalmic applications, and may be used for delivering pharmaceutical agents to the front of the eye and/or the back of the eye.
本文提供了有助于颗粒在粘液中传输的颗粒、组合物和方法。这些微粒、组合物和方法在某些情况下可用于眼科和/或其他应用。在某些实施方案中,这些组合物和方法可能涉及颗粒表面涂层的改性,例如水溶性较低的药剂颗粒。此类组合物和方法可用于实现药剂颗粒通过体内粘液屏障的高效运输,应用范围广泛,包括药物输送、成像和诊断应用。在某些实施方案中,包括此类微粒的药物组合物非常适合眼科应用,可用于将药剂输送到眼球前部和/或眼球后部。
