July 21 (Reuters) - Novo Nordisk NOVOb.CO accused Eli Lilly LLY.N of falsely claiming that its weight-loss medicines are more effective, in a U.S. lawsuit, escalating a rivalry between the leaders of the lucrative obesity drug market.

The U.S. Centers for Medicare & Medicaid Services this month launched a pilot that initiated broader access to Novo and Lilly's popular GLP-1 drugs as weight-loss treatments at $50 a month for eligible beneficiaries.

Here are the details of the launch and pricing for their currently approved weight-loss drugs:

Foundayo (orforglipron): Approved in the United States in 2026 as a once-daily oral GLP-1 therapy for weight loss. Available in the U.S. starting April 6 through the LillyDirect platform, with broader rollout to retail pharmacies and telehealth providers to follow.

Zepbound: Approved in the U.S. in 2023. The drug, chemically known as tirzepatide, is also available in Canada, Australia, Japan, China, India, United Kingdom and the European Union.
