Summary
Benzodiazepines (BZ) and non-benzodiazepines (non-BZ) are common hypnotics, classified by elimination speed. These drugs modulate gamma-aminobutyric acid (GABA) receptors to alter sleep patterns.
Area of Science:
- Pharmacology
- Neuroscience
- Sleep Medicine
Context:
- Current hypnotic medications include benzodiazepines (BZ) and non-benzodiazepines (non-BZ).
- These drugs are widely prescribed for sleep disorders.
- Understanding their mechanisms and classifications is crucial for effective treatment.
Purpose:
- To classify available hypnotics based on pharmacokinetic profiles.
- To explain the mechanism of action of benzodiazepines (BZ).
- To highlight the role of gamma-aminobutyric acid (GABA) in hypnotic drug effects.
Summary:
- Hypnotics are categorized into four groups based on their elimination rates: ultra-rapid, rapid, relatively slow, and slow elimination.
- Benzodiazepines (BZ) function by modulating gamma-aminobutyric acid (GABA)-ergic transmission.
- BZ drugs bind to specific receptors, influencing the GABA receptor-chloride channel to alter sleep.
Impact:
- Provides a framework for understanding hypnotic drug pharmacokinetics.
- Clarifies the neurobiological basis of how common sleep medications work.
- Informs clinical practice regarding the selection and use of hypnotics.

1.8K
CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...

2.3K
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...

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

01:20Sedatives and Hypnotics Drugs: Barbiturates
1.5K
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...

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 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...
