The Danish drugmaker Novo Nordisk contends that semaglutide, the active ingredient in Ozempic and Wegovy, is too complex for those manufacturers to make safely.

Novo Nordisk has nominated semaglutide for inclusion in the FDA’s Demonstrable Difficulties for Compounding list, which includes drugs that are too complicated to produce and could pose substantial safety risks to patients if manufactured incorrectly.

A new study found a link between NovoNordisk’s blockbuster drug Ozempic and a reduced risk of Alzheimer’s disease. 23andMe, the company that popularized consumer genetic testing, could soon be delisted from the Nasdaq.

The agency posted documents this week that the drugmaker had requested the drug be placed on the FDA's "Demonstrable Difficulties for Compounding Lists."

Novo Nordisk on Tuesday asked the U.S. Food and Drug Administration to ban compounding pharmacies from making copycat versions of its popular weight-loss and diabetes drugs, which it said were too complex for those manufacturers to produce safely.

Novo Nordisk wants the Food and Drug Administration (FDA) to prevent compounding pharmacies from manufacturing their own versions of the company’s popular weight loss drug Wegovy and diabetes treatment Ozempic,
