After the success of weight loss drugs, including Novo Nordisk’s (NVO) Ozempic and Wegovy, researchers are now testing how people can maintain their weight loss after they stop taking the medications, Betsy McKay of The Wall Street Journal reports. Makers of the weight-loss drugs are also facing a big problem, that many people stop taking the drugs whether its due to insurance, side effects, or not wanting to take it long term. Drugmakers are now designing treatments to help maintain weight. Amgen (AMGN) is developing a long-acting injectable while Eli Lilly (LLY) and Novo Nordisk now say their respective drugs are for weight loss and maintenance.
