Sedatives and Hypnotics Drugs: Barbiturates01:20

Sedatives and Hypnotics Drugs: Barbiturates

1.1K
Sedatives and hypnotics encompass a drug class that acts on the central nervous system (CNS) to alleviate anxiety, promote relaxation and induce sleep.These drugs function by amplifying the actions of the neurotransmitter γ-aminobutyric acid (GABA), resulting in reduced neuronal activity. Barbiturates, a subset of sedatives and hypnotics first synthesized in the late 1800s, are categorized into ultra-short, short, intermediate, and long-acting groups based on their duration of effect. A...

Sedatives and Hypnotics Drugs: Benzodiazepines

913
Benzodiazepines have both sedative and hypnotic properties. They include compounds such as diazepam (Valium) and alprazolam (Xanax). Structurally, their cores are similar, consisting of the fusion of a benzene ring and a diazepine ring, but they share a common mechanism of action in the central nervous system (CNS).
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 Drugs: Miscellaneous Agents

606
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
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: Overview01:23

Sedatives and Hypnotics: Overview

1.6K
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
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...

What is Natural Selection?01:32

What is Natural Selection?

129.6K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Summary

Current ambulatory sedation options like midazolam and propofol are common. Newer agents such as dexmedetomidine and remimazolam show promise, but the ideal sedative drug remains elusive.

Area of Science:

  • Anesthesiology
  • Pharmacology

Background:

  • Ambulatory procedural sedation manages patient anxiety, pain, and discomfort during various procedures.
  • Midazolam and propofol are established agents with extensive clinical experience.

Purpose of the Study:

  • To review recent comparative studies on commonly used and novel drugs for adult ambulatory sedation.
  • To evaluate the efficacy and safety profiles of different sedative agents.

Main Methods:

  • Review of recent comparative studies on sedative drugs.
  • Analysis of pharmacological properties and clinical outcomes.

Main Results:

  • Midazolam and propofol are widely used with established benefits.
  • Ketofol (ketamine-propofol mixture) efficacy is challenging to ascertain.
  • Dexmedetomidine offers advantages but has prolonged hemodynamic effects.
  • Remimazolam shows potential as an ideal sedative, with ongoing phase 3 studies.

Conclusions:

  • No single sedative drug currently possesses all ideal properties.
  • Drug selection for ambulatory sedation is multifactorial, depending on procedure, patient, and provider factors.
  • Definitive guidance on the best sedative for specific situations is not yet available from current literature.
