Purpose:
Anxiolytic and possible side effects of clonidine 150 μg compared to midazolam 7.5 mg for premedication in surgical wisdom tooth extraction were evaluated.
Methods:
In a prospective, randomized, double-blind crossover trial, ten patients undergoing bilateral wisdom tooth surgery received clonidine or midazolam orally 1 h before the treatment. Patients receiving midazolam for the first surgery received clonidine at the second surgery and vice versa. The anxiolytic efficacy was evaluated with a visual analogue scale (VAS) upon admission and 30, 50 and 60 min after administration of the medication. Patient satisfaction was recorded on a VAS after surgery and 7 days postoperatively.
Results:
As soon as 30 min after administration of midazolam (p < 0.03) and clonidine (p < 0.02), an anxiolytic effect was recorded. Both medications did not differ in patient satisfaction.
Conclusion:
Oral administration of clonidine 150 μg and midazolam 7.5 mg were rated as medications with equal anxiolytic effects before wisdom tooth surgery under local anesthesia.

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...

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...
