Market Analysis and Sales Projections for Lunesta (Eszopiclone)

Introduction to Lunesta

Lunesta, also known as eszopiclone, is a non-benzodiazepine type GABA_A agonist used for the treatment of insomnia. It was originally discovered and developed by Sunovion Pharmaceuticals Inc. and has been marketed in the United States since April 2005. Lunesta is notable for its lack of restrictions on the length of use and its favorable safety profile, including minimal issues with dependency, carry-over effects, or tolerance development with long-term use[1].

Historical Market Performance

Historically, Lunesta was one of the highest-selling insomnia treatments. In 2013, it generated approximately $617.9 million in sales, dominating the insomnia treatment market. However, the market faced a significant decline from 2013 to 2016 due to the generic erosion of Lunesta in the United States, which had a substantial 71.4% share of the global market at that time[3].

Impact of Generic Erosion

The introduction of generic versions of Lunesta led to a sharp decline in its sales. By 2023, Lunesta's sales were expected to drop to $99.6 million across the seven major markets, with a negative compound annual growth rate (CAGR) of 16.7% over the forecast period. This decline was largely driven by the loss of patent protection and the subsequent entry of generic competitors[3].

Current Market Trends

Despite the decline, the insomnia treatment market has shown signs of recovery. New drugs, such as Merck & Co’s Belsomra and Eisai’s E-2006, have entered the market, contributing to the recovery. Belsomra, in particular, is forecasted to become the market leader by 2023, generating approximately $458.6 million in sales across the seven major markets[3].
