4-Aminopyridine to Treat Skin Burns

Burn treatment has not appreciably changed in decades. Most treatments focus on infection prevention and control, as well as fluid management. This is because burns are universally infected with bacteria allowed to infiltrate deeper tissues by the absence of a skin barrier. If bacteria can now get into these tissues, the problem is only made worse by the large amount of hydration that now can get out into the environment from the open wound. Desiccation sets in with deeper tissues losing fluids. This renders tissue significantly more susceptible to further infection, as dry tissues are less perfused and less capable of fighting infectious insults. Desiccation also robs burned patients of fluids vital to sustain cardiopulmonary function. Without skin, patients essentially lose fluids and cannot perfuse even the most vital organs with time. Research in the field focuses on preventing complications and temporizing these two factors. No regenerative treatments are currently offered to accelerate wound healing, and few investigative treatments are ready for translation to human trials. Most of the pipelines for future treatment involve long development timelines and still focus chiefly on infection control instead of driving tissue to regenerate and heal faster. A significant gap is the need for a regenerative burn treatment that can be trialed while still allowing the use of current protocols. An adjuvant regenerative burn treatment is needed. The purpose of this study is to evaluate the role of local 4-aminopyridine (4-AP) on the treatment of burn wounds to accelerate healing.
