Topical gel helps burn wounds heal faster using an existing FDA-approved drug

Article excerpt

Researchers at the Terasaki Institute and University of Arizona have formulated a topical gel using 4-aminopyridine, an existing FDA-approved drug, that accelerates burn wound healing to near-complete closure in just 21 days. The breakthrough, published in Biomaterials, repurposes a known medication in a new delivery method rather than introducing an entirely novel compound. The gel's ability to speed healing could significantly reduce recovery time and complications for burn patients, offering a practical advancement that bypasses lengthy drug approval timelines since the active ingredient already has FDA clearance.
