Background:
Doxepin is a tricyclic compound that has been used extensively for the treatment of depressive and anxiety disorders for approximately thirty years. It was noted early to have sedative effects and assist with the improvement of disrupted sleep patterns, but in higher antidepressant doses it was also noted to have significant anticholinergic and antinoradrenergic properties. These properties led to significant dose-limiting side effects, which at times precluded its effective use. Recently, doxepin has seen renewed interest in low doses as an H1 specific antagonist in sleep disorders.
Objective:
The review seeks systematically to examine currently published data on the use of doxepin for the treatment of insomnia, and its pharmacological basis.
Methods:
Medline articles showing from a search of 'doxepin and insomnia' were included in the review.
Results/Conclusion:
Currently available data support the use of low-dose doxepin as preferential H1 antagonist for the treatment of primary insomnia. There are likely preferential effects upon sleep maintenance insomnia compared with sleep initiation given the role of histamine in the sleep-wake cycle.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Anxiolytic Drugs: Overview
Primary Types of Anxiolytic Drugs
1. Benzodiazepines:
Benzodiazepines bind to the GABA-A receptor in the brain, enhancing GABA's interaction. This action reduces neurotransmission, effectively blocking anxiety-associated limbic circuitry.
Sedatives and Hypnotics Drugs: Benzodiazepines
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
