Eli Lilly said on Thursday that India's drug regulator had approved the launch of pre-filled injector pens of its blockbuster weight-loss drug, Mounjaro, giving it more options to compete with Novo Nordisk's recently launched Wegovy.

Some doctors are concerned that patients taking weight loss drugs like Wegovy may be losing too much lean mass. A combination therapy might change that.

Patients who took an experimental drug from Eli Lilly & Co. together with Novo Nordisk A/S’s Wegovy maintained muscle while losing weight, offering a potential solution to one of the key problems that’s emerged with popular obesity shots.
