SWELLABLE PARTICLES FOR DRUG DELIVERY |
| 摘要 |
<p>Swellable particles for delivery of a drug or other working agent to the pulmonary system are provided. The swellable particles include a dehydrated (dry) aerodynamic particle diameter of 5μm or less to enable delivery to the respiratory tract, such as for example to the tracheo-bronchial airways of the upper respiratory tract and/or to the alveolic regions of the deep lung, and a hydrated particle diameter that is greater than 6μm volume mean diameter to retard or prevent their phagocytosis by the macrophages present in airways of the respiratory tract.</p> |
