What medication is indicated for insomnia and marketed as Silenor?

The medication indicated for insomnia and marketed as Silenor is Doxepin. Doxepin is a tricyclic antidepressant that, at lower doses, is used primarily for its sedative effects to help with sleep. The formulation of Doxepin specifically for insomnia is formulated to avoid the higher doses that are typically used for depression and anxiety disorders, focusing instead on the substance's ability to enhance sleep quality without the risks associated with many other sleep medications.

In sleep disorders, the sedative properties of Doxepin are beneficial in promoting sleep onset and maintenance. It works by blocking histamine receptors, which are responsible for wakefulness in the brain, thereby fostering a more restful sleep. This makes Doxepin, particularly in its Silenor brand formulation, a targeted option for patients struggling with insomnia.

The other medications listed typically do not focus specifically on the treatment of insomnia in the same way that Doxepin does at low doses. While some may have sedative properties, they are primarily indicated for other disorders such as depression or anxiety rather than for sleep issues.
