FDA Proposal Would Leave Semaglutide, Tirzepatide, and Liraglutide Off 503B Bulks List - The National Law Review
FDA proposes to exclude semaglutide, tirzepatide, and liraglutide from the 503B bulks list, limiting outsourcing facilities' ability to compound these drugs without individual patient prescriptions.
