Classification
Below are examples of available sedative drugs.
Alcohols
Ethylene glycols
Anti-adrenergics
Inhibitors of the adrenergic alpha-2 receptor can cause sedation.
- Dexmedetomidine. In some settings, dexmedetomidine may cause less drug-related side effects and adverse reactionss than non-selective benzodiazepines.[1]
Anti-histamines
Gamma-aminobutyric acid (GABA) agonists
Gamma-aminobutyric acid (GABA) the major inhibitory neurotransmitter in the central nervous system.[2] Drugs that increase the effect of GABA are called GABAergic.
Many sedatives work by increasing receptiveness of GABAA receptors.
Barbituates
Barbituates are GABAergic by increasing receptiveness of the GABAA receptors. Barbituates do this by increasing the duration of openings of channels in the cell membrane.[2]
- Phenobarbital
Benzodiazepines
Benzodiazepines are non-selective agonists by increasing receptiveness of the GABAA receptors. Benzodiazepines do this by increasing the frequency of openings of channels in the cell membrane.[2]
Benzodiazepine receptors are BZ1 and BZ2.
BZ1 selective agonists
Serotonin (5-HT) agonists
Agonists of the 5-HT1A receptor can cause sedation.
Other
Adverse effects
Sedatives taken for insomnia are associated with increased mortality with increasing mortality with increasing frequency of use of sedatives.[4][5]
