A group of obscure yet powerful players in the prescription drug industry are under the microscope. On Tuesday, at a Senate hearing in D.C., the head of pharmaceutical giant Novo Nordisk blamed the health insurance industry and pharmacy benefit managers, or PBMs, for allegedly making products like the weight loss drug Ozempic way more expensive in the U.S. than it is in other countries. A few days before that, the Federal Trade Commission sued three of the country's largest PBMs for allegedly using unfair tactics to artificially inflate the price of insulin.
