The Food and Drug Administration (FDA) is withdrawing approval for four abbreviated new drug applications (ANDAs) because the manufacturers informed the FDA that these drugs are no longer being sold. The manufacturers requested this action and have given up their right to a hearing. As of April 14, 2025, these drugs cannot legally be sold or introduced into interstate commerce in the U.S. unless they have an approved application. However, any remaining stock of these drugs can be used until they expire or are sold out.
Simple Explanation
The FDA is taking away permission for some medicines because the companies said they don't sell them anymore. This means people can't legally sell these medicines in the U.S. unless they get new permission.
