Target receptors for anxiolytics and hypnotics: from molecular pharmacology to therapeutics: Workshop on "Target Receptors for Anxiolytics and Target Receptors for Anxiolytics and Hypnotics book From Molecular Pharmacology to Therapeutics," Monte Carlo, November Benzodiazepine (BZ) anxiolytics mediate their clinical effects by enhancing the effect of γ-aminobutyric acid (GABA) at the GABA-A receptor.

Classical BZ full agonists such as diazepam, which maximally enhance the function of GABA-A receptors, are effective anxiolytics but carry unwanted side effects including sedation, dependence and abuse liability, limiting their by: 1) Caused by down-regulation of GABA receptors 2) Develops after weeks of use 3) Sedative/hypnotic effects are more prone to tolerance than the anxiolytic effect 4) Since they affect the same receptors as ethanol in this matter, cross-tolerance to.

Curr Opin Anesthesiol ; 9: –5. Until recently the pharmacology of drugs used to treat anxiety (anxiolytics) and insomnia (hypnotics) were identical because the same drugs were used for both purposes.

While the anxiolytic action of hypnotics was probably an advantage, the hypnotic action of anxiolytics was a major by: 8. Increased susceptibility to these various adverse effects in elders may be a result of the pharmacokinetic and pharmacodynamic changes associated with aging, such as diminished glomerular filtration, changes in the density and activity of target receptors, reduced liver size and hepatic blood flow, and decreased cardiac output (Pollock et al.

Hypnotics and anxiolytics should therefore be reserved for short courses to alleviate acute conditions after causal factors have been established. Benzodiazepines are the most commonly used anxiolytics and hypnotics; they act at benzodiazepine receptors which are associated with gamma-aminobutyric acid (GABA) receptors.

They do not resemble benzodiazepines or barbiturates in their structure. Anxiolytics work by targeting key chemical messengers in the brain. This is thought to help decrease abnormal excitability.

Side effects of anti-anxiety drugs are similar. A chemically diverse group of agents are classified as sedative-hypnotics, linked by the ability to induce calm, sedation, sleep, respiratory depression, and coma.

(For a detailed review of the pharmacology, see Ciraulo )Many of the drugs share the property of exerting their pharmacological effects at the gamma-aminobutyric acid (GABA) receptor, but recent research. Anxiolytic-hypnotics agents are used to alter an individual’s responses to environmental stimuli.

These agents are referred to as anxiolytics (prevent feelings of tension or fear), sedatives (help patient feel calm and unaware of their environment), and hypnotics (help patients sleep). Here is a table of commonly encountered diuretic agents.
