The invention provides a dressing composition comprising a bisphosphonate matrix metalloproteinase (MMP) inhibitor covalently bound to a polymer wherein, when the dressing is contacted with a wound, substantially all of the bisphosphonate remains with the dressing composition and is unable to enter the wound tissue. The invention also provides for a method of treatment of a wound by contacting a dressing composition comprising a covalently bound MMP inhibitor with the wound fluid to thereby selectively inhibit one or more MMP's in the wound fluid without inhibiting those in the wound tissue.
