(Reuters) -Eli Lilly ( LLY ) on Thursday launched in India its diabetes and weight-loss drug, Mounjaro, which has already clocked in over $20 billion in global sales since its initial U.S. launch in 2022.

India, the world's most populous country, has high obesity rates and the second-highest number of people with type 2 diabetes. Around 11% of Indian adults are expected to become obese by 2035, according to the World Obesity Federation Atlas.

Here are the local and international drugmakers also eyeing the Indian market and looking to introduce rivals to Lilly's drug:

NOVO NORDISK

The Danish drugmaker had said it aims to launch its blockbuster weight-loss drug, Wegovy, in India by 2026.

The active ingredient in Wegovy is semaglutide, which is likely to go off-patent in 2026 in India.

Wegovy and Lilly's Mounjaro belong to the same class of treatments called GLP-1 agonists, which soared into popularity globally triggering a shortage of supply. GLP-1 drugs mimic a gut hormone that helps control blood sugar levels and slow digestion, making people feel fuller for longer.

SUN PHARMA

Sun Pharmaceutical , India's largest drugmaker by revenue, is developing its own GLP-1 treatment, utreglutide, for weight loss and type 2 diabetes.

The drugmaker said earlier this month it expects to launch the drug in the next four to five years.

BIOCON

Indian drugmaker Biocon is developing its own version of Novo's Wegovy, as the drug is set to lose exclusivity next year in emerging markets such as India, Brazil, Mexico, and Saudi Arabia.

ZYDUS LIFESCIENCES

India's Zydus Lifesciences is developing the generic version of Semaglutide and plans on launching the drug after its patent expires in India.

CIPLA

Cipla, India's third-largest drugmaker by sales, is among the Indian drugmakers making cheaper versions of Novo's Wegovy.

Cipla has also said it is open to partnering with Lilly to market Mounjaro in India.

DR. REDDY'S

India's Dr. Reddy's has said it plans to launch generic versions of Semaglutide in all the markets as Novo's patent expires.

LUPIN

India's Lupin is another generic drugmaker looking to grab a share of the burgeoning obesity treatment market with its own version of Novo's Wegovy.

NATCO, MANKIND PHARMA, AUROBINDO PHARMA

Media reports say India's Natco Pharma, Mankind Pharma, Aurobindo Pharma are also developing cheaper versions of Novo's Wegovy.

Reuters was not able to independently verify the reports.
