Introduction to Eszopiclone
Eszopiclone, marketed under the brand name Lunesta, is a nonbenzodiazepine hypnotic agent used for the treatment of insomnia. It is the S-enantiomer of zopiclone, another commonly used sleep aid. Here, we will delve into the clinical trials, market analysis, and future projections for eszopiclone.
Clinical Trials and Efficacy
Comparison with Zopiclone
A significant clinical trial comparing eszopiclone with zopiclone was conducted to assess their efficacy in treating insomnia. This Phase III, single-center, randomized, double-blind, double-dummy, parallel-group, non-inferiority trial involved 199 patients who were randomized to receive either zopiclone 7.5 mg or eszopiclone 3 mg orally for four weeks[1].
- Primary Endpoint: The primary efficacy analysis was based on the Insomnia Severity Index (ISI) after four weeks of treatment. The results showed that eszopiclone was non-inferior to zopiclone, with no statistically significant difference in ISI values between the two groups at the end of the treatment period.
- Secondary Endpoints: Polysomnography data revealed that eszopiclone increased total sleep time and improved sleep efficiency, similar to zopiclone.
- Safety Profile: Both treatments had a similar safety profile, with common adverse events including dysgeusia, headache, dizziness, irritability, and nausea.
Long-Term Efficacy and Safety
Clinical trials supporting the efficacy of eszopiclone have also included longer-term studies. For instance, premarketing development programs for Lunesta involved clinical effectiveness studies that lasted up to six months. These studies included approximately 1550 patients and demonstrated the efficacy of eszopiclone in reducing sleep latency and improving sleep quality[4].
