Mechanism of action

The mechanism of action for the sleep-promoting effects of is not definitively known, it differs from the currently available sleep-promoting agents in that the effects are mediated through the histaminergic system. The active ingredient in SO-101, doxepin HCl, is known to be a highly potent histamine antagonist. Histamine blocking has been demonstrated to reduce wakefulness and is thought to promote the initiation and maintenance of sleep.
