17 . The method of claim 16 , wherein at least five injections of the collagenase are administered to five injection sites within the affected area.
18 . The method of claim 17 , wherein at least ten injections of the collagenase are administered to ten injection sites within the affected area.
19 . The method of claim 1 , any of the preceding claims , wherein the affected area of EFP has an area of about 1 cm 2 to about 200 cm 2 .
20 . The method of claim 1 , wherein a plurality of subdermal injections of the collagenase are administered and wherein the distance between injection sites is at least about 1 to about 4 cm.
21 . The method of claim 20 , wherein the distance between injection sites is about 2 to about 3 cm.
22 . The method of claim 19 , wherein the area affected by EFP has a length of about 10 cm and width of about 8 cm.
23 . The method of claim 22 , wherein there is a distance of about 2.5 cm between injection sites.
24 . The method of claim 1 , wherein each injection has a volume of about 0.5 ml.
25 . The method of claim 1 , wherein each injection has a volume of about 0.1 ml.
26 . A method of treating or reducing EFP in a patient comprising administering one or a plurality of subdermal injections of the collagenase within an area affected by EFP, wherein the total dose of the collagenase administered to the affected area is between about 5 to about 5000 ABC units, and wherein the plurality of injections are each between about 5 to about 200 ABC units, and wherein the plurality of injections are administered at a plurality of injection sites.
27 . The method of claim 26 , wherein a plurality of subdermal injections of the collagenase are administered at a plurality of injection sites.
28 . The method of claim 26 , wherein the concentration of the collagenase administered is between about 50 to about 2000 ABC units per milliliter.
29 . The method of claim 26 , wherein each injection of the collagenase is administered in a volume of about 0.5 ml or less.
30 . The method of claim 26 , wherein the dose of the collagenase per injection is between about 5 to about 200 ABC units.
31 . The method of claim 26 , wherein the total dose of the collagenase administered to the affected area is between about 5 to about 2000 ABC units.
32 . The method of claim 31 , wherein the total dose of the collagenase administered to the affected area is between about 5 to about 1000 ABC units.
33 . The method of claim 26 , wherein the collagenase is purified from Clostridium histolyticum.
34 . The method of claim 26 , wherein the collagenase is a recombinant collagenase.
