Abstract
The invention provides wound dressings and methods of their use, especially for the treatment of chronic, non-healing wounds. The wound dressings are composed of a support matrix, such as cotton cellulose, and an active agent associated with the support matrix. The active agent may be a protease inhibitor or a protease sequestrant, in particular an inhibitor or sequestrant of a neutrophil-derived cationic protease such as elastase.
