Lemborexant for the Treatment of Residual Insomnia in Major Depressive Disorder (MDD)

Dayvigo (lemborexant compound) is an orexin antagonist that acts on the arousal and sleep neural networks of the brain to regulate sleep-wake cycles and is used in the treatment of insomnia characterized by difficulties with sleep.

The placebo is an inactive sugar pill that looks and tastes identical to the lemborexant pill.
