Eszopiclone acts by a different mechanism than Mirtazapine, with indications that barely overlap. Comparing the two is useful when a clinician has mentioned both in the same context or the patient wants to understand why one was prescribed instead of the other.
Mechanisms compared
Eszopiclone: L'eszopiclone est un modulateur allostérique positif du récepteur GABA-A, sur un site proche du site de liaison des benzodiazépines.

Can Eszopiclone and Mirtazapine be combined? ▾
Whether they can be combined depends on the indications and the interaction profile of each. If both are in a single prescription, the prescriber has weighed it; in self-medication they should never be combined.
