What is the brand name of Doxepin?

Doxepin is primarily recognized by the brand name Silenor. This medication is a tricyclic antidepressant that is commonly used to treat conditions such as depression and anxiety disorders, as well as being effective for managing insomnia due to its sedative properties. The specific formulation as Silenor is approved for the treatment of insomnia, distinguishing it from other formulations of doxepin that may be used for treating more general depressive or anxiety symptoms.

The other brand names listed, such as Tofranil, Norpramin, and Pamelor, are actually associated with different tricyclic antidepressants. Tofranil refers to imipramine, Norpramin is the brand name for desipramine, and Pamelor is associated with nortriptyline. Each of these medications works through similar mechanisms but is distinct in terms of their chemical makeup and specific indications. Thus, Silenor is the correct answer as it directly refers to doxepin in its marketed form.
