Objective:
To compare the effectiveness and tolerability of two hypnotic agents, trazadone (Desyrel) and zaleplon (Sonata) on psychiatric inpatients with insomnia.
Methods:
Fifteen patients who were psychiatric inpatients were assigned openly and randomly to receive either trazodone (50-100 mg) or zaleplon (10-20 mg) doses on an "as-needed basis" and followed throughout their hospital stay. Efficacy and side effect profile were subsequently assessed.
Conclusion:
This pilot study suggests that trazodone may be a better agent to promote longer, deeper subjective quality sleep for psychiatric inpatients with insomnia in terms of effectiveness. However, tolerability was much better with zaleplon as daytime residual side effects were less.

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...

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...
