The U.S. Food and Drug Administration today established a “green list” import alert to help stop potentially dangerous GLP-1 (glucagon-like peptide-1) active pharmaceutical ingredients (APIs) from unverified foreign sources from entering the U.S. market. To protect patients who use these compounded drugs, the green list will include GLP-1 APIs from facilities the agency has inspected or evaluated that appear to be in compliance with the FDA’s rigorous standards – standards applicable to all APIs manufactured in the U.S. APIs from other sources are subject to detention without physical examination.
