The U.S. Food and Drug Administration (FDA) has approved the first drug to treat severe frostbite, the agency announced Feb. 14.
The drug, called iloprost, opens up blood vessels and prevents blood clotting in frostbitten patients. Following positive results in a small clinical trial, the drug has now been approved for use, under the brand name Aurlumyn, to treat severe frostbite in adults and reduce the need for finger or toe amputation.
