Side-effects of topical proteolytic enzyme treatment

The results of this study indicate that short term treatment of wounds with topical enzymes appears to be safe and is accompanied by no clinically significant side-effects. Topical wound treatment with this enzyme did not interfere either with healing of experimental wounds or the activity of the antibiotics. Wounds subjected to this enzyme treatment exhibited a normal capacity to resist infection, even though this enzyme interferred with leukocyte phagocytosis in vitro. The potential benefits of this treatment in experimental wounds as an adjunct to antibiotics considerably outweigh its damaging effects. Its clinical use in patients must await the results of carefully controlled clinical trials in which the efficacy of this treatment is evaluated.
