They swap out capsules for tablets. By piling up patents, drug companies delay the day when competitors can introduce similar, cheaper products. Jazz Pharmaceuticals has figured out a way to push the boundaries even further — a feat that demonstrates the lengths to which drug makers go to eke out extra profits and that two federal courts have now ruled was improper.

People who stopped taking semaglutide gained back, on average, two-thirds of the weight they lost within a year, according to a study published in August 2022 in the journal Diabetes, Obesity, and Metabolism. Novo Nordisk funded the trial. “Some people don’t have an awareness that this might have to be a medication that will be lifelong,” said Alexandra Sowa, an obesity medicine physician in New York. Dr. Sowa said more than half of her new patients are asking about semaglutide. (Janin, 2/27)
