Anxiolytic Drugs: Benzodiazepines and Buspirone
1.2K
Benzodiazepines are a class of anxiolytic drugs known for their rapid efficacy and high therapeutic-to-lethal dose ratio, but with a potential risk of drug dependence. These drugs are lipophilic, allowing for rapid absorption after oral administration, eventually reaching the central nervous system (CNS). Once in the CNS, benzodiazepines bind to the allosteric site of the GABAA receptor. This binding enhances the inhibitory effects of the neurotransmitter GABA. By doing so, they prevent...

Long-term Depression
2.6K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

CNS Depressants: Barbiturates and Benzodiazepines
466
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...

Sedatives and Hypnotics Drugs: Benzodiazepines
375
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...

Anxiolytic Drugs: Overview
480
Anxiolytic drugs are vital in managing anxiety disorders by effectively alleviating symptoms such as excessive fear, tachycardia, and tremors. There are several classes of anxiolytic medications, each with unique mechanisms of action and potential side effects.
Primary Types of Anxiolytic Drugs
1. Benzodiazepines:
Benzodiazepines bind to the GABA-A receptor in the brain, enhancing GABA's interaction. This action reduces neurotransmission, effectively blocking anxiety-associated limbic...

Sedatives and Hypnotics Drugs: Barbiturates
463
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.
