Brief Summary

Many patients suffer from chronic non-healing wounds as well as acute wounds. There is a need to develop treatments to accelerate and improve healing of chronic and acute wounds. More research is needed to evaluate the role of 4-aminopyridine (4-AP), a promising new agent with an excellent safety profile, on wound healing. The investigational treatment will be used to evaluate the role of (4-AP) on the treatment of wounds to accelerate wound healing in healthy adults. The purpose of this study is to evaluate the role of 4-AP on the treatment of wounds to accelerate healing. The investigational treatment will be used to test the hypothesis that 4-AP can speed wound healing.

Eligibility Criteria

Inclusion Criteria: * Otherwise healthy adult patients without skin conditions effecting the skin of the axilla or upper inner arm. * Cognitive ability to evaluate wound healing, report sensory and motor deficit during examination. * Eligible for standard of care plan for wound closure by secondary intention (normal healing without intervention). * Adults subject aged 18-70 * Ability to give written informed consent. * Capable of safely coming in for follow up visits on all scheduled appointments. Exclusion Criteria: * History of multiple sclerosis, stroke or any other diagnosed neurological disorder * History of hypersensitivity to AMPYRA® or 4-aminopyridine * Current use of aminopyridine medications, including other compounded 4-AP * Suspected renal impairment based on the Choyke questionnaire. * History of difficult compliance with timely follow up * Patients outside the age range * Unable to provide informed consent. * Patients with a known history of a seizure disorder (4-AP overdose can, in selected cases, result in limited seizure activity). * Patients with a concomitant traumatic brain injury. * Patients unable to communicate. * Patients unwilling to complete the study requirements. * Patients currently taking organic cat-ion transporter 2 (OCT2) inhibitors, e.g. Cimetidine. * Pregnancy, breastfeeding or incarcerated individuals. * Non-English speaking * Patients unable or unwilling to take calibrated (with gauge) photographs of their wounds
