Understanding Belsomra

Belsomra is an orexin receptor antagonist.

These receptors regulate sleep and wakefulness, stress responses, and appetite.

Belsomras only approved use is for adults withinsomniaor difficulty falling asleep or staying asleep.

It binds to the gamma-aminobutyric acid-A (GABA-A) receptor at the same site wherebenzodiazepine medicationsbind.

This causes the receptor to attract more of the GABA neurotransmitter, which results in less neuron firing.

The outward result is a sedative effect that helps induce and maintain sleep.

You may hear Ambien referred to as a Z-drug.

All of these have mechanisms of action that are similar to those of Ambien.

These medications can cause drowsiness or sedation and taking them together is more likely to cause side effects.

Frequent contributors to sleep difficulties include:
