A novel method and composition is disclosed for treating burn injuries on human skin by promoting healing of the damaged skin. In particular, a topical liquid drug formulation is used to treat burn injuries caused by exposure of the skin to heat (thermal burns), the sun or ultraviolet radiation (sunburn), ionizing radiation (radiation burns), chemicals (chemical burns) and electricity (electrical burns). The topical burn treatment liquid contains clotrimazole as the active pharmaceutical ingredient to promote the healing of the burn damaged skin by reducing the edema, erythema, blistering, pain and other symptoms associated with burns, as well as preventing the spread of the burn damage and promoting healing.
