Lunesta vs Eszopiclone: are they the same?
Lunesta is a commercial brand whose active ingredient is exactly Eszopiclone. This page explains what that means in practice: where they differ (brand, manufacturer, price, available strengths), why they are clinically equivalent, and when the brand or an authorised generic is the better choice.
Are they the same?
Yes — Lunesta contains Eszopiclone as its active ingredient. Talking about "Lunesta" in clinical terms is the same as talking about Eszopiclone at the dose strengths 1mg, 2mg, 3mg. The differences from the authorised generic are brand, manufacturer (Sunovion), excipients, tablet appearance and price — not the active molecule itself.
When Lunesta is used
Lunesta is approved in adults for the treatment of insomnia, including difficulty falling asleep and difficulty maintaining sleep.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: Eszopiclone is a positive allosteric modulator of the GABA-A receptor at a site close to the benzodiazepine binding site.
Brand or generic — which to choose?
For most patients, authorised generics of Eszopiclone are clinically equivalent substitutes for Lunesta and typically cost substantially less. The practical differences are manufacturer, excipients (rarely matters except in specific sensitivities), tablet appearance and price. The brand is preferred by some patients for personal reasons or insurance coverage; the generic is the default when cost matters.
