Antidepressant Drugs: MAOIs and Other Agents01:23

Antidepressant Drugs: MAOIs and Other Agents

547
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

567
Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs

915
Tricyclic Antidepressants (TCAs), including Desipramine (Norpramin), Imipramine (Tofranil), Clomipramine (Anafranil), and Amitriptyline (Elavil), inhibit serotonin and norepinephrine reuptake and also block other receptors. They are used for depression, pain conditions, and insomnia. Common adverse effects include anticholinergic effects, sedation, orthostatic hypotension, and weight gain. They have a narrow therapeutic window and so require plasma-level monitoring. Abrupt discontinuation can...

G-protein Coupled Receptors01:21

G-protein Coupled Receptors

127.9K
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

Drugs Affecting Neurotransmitter Release or Uptake01:21

Drugs Affecting Neurotransmitter Release or Uptake

1.3K
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...

Antidepressant Drugs: Overview

1.0K
Antidepressant drugs are a class of medications primarily used for treating various mood disorders, including major depression, anxiety disorders, and other related conditions. These medicines work by modulating the neurotransmitter balance within the brain, alleviating depressive symptoms. Antidepressants can be broadly categorized into several groups according to their mechanism of action and chemical structure: Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin-Norepinephrine...

Area of Science:

  • Neuroscience
  • Pharmacology
  • Molecular Biology

Background:

  • The serotonergic system, utilizing serotonin (5-hydroxytryptamine, 5-HT), is crucial for numerous CNS functions including mood, cognition, and behavior.
  • 5-HT interacts with various neurochemical systems via numerous 5-HT receptors and autoreceptors, influencing neuron activity.
  • Autoregulation of 5-HT neuron activity involves specific receptors (e.g., 5-HT1A, 5-HT1B, 5-HT1D, 5-HT2B, 5-HT7) and the serotonin transporter.

Purpose of the Study:

  • To highlight the complexity of the serotonergic system in the CNS.
  • To emphasize the importance of understanding 5-HT receptor interactions for therapeutic development.
  • To underscore the need for further research into the regional and neuronal distribution of 5-HT controls.

Main Methods:

  • Review of existing literature on serotonergic system mechanisms.
  • Analysis of molecular actors involved in 5-HT neuron autoregulation.
  • Discussion of extrinsic loops involving other neurotransmitters impacting 5-HT activity.

Main Results:

  • The serotonergic system's control mechanisms are multifaceted and involve numerous receptors and autoreceptors.
  • 5-HT neuron activity is modulated by intrinsic autoregulation and extrinsic interactions with other neurotransmitter systems.
  • The distribution of 5-HT controls is likely not uniform across CNS regions and neuronal populations.

Conclusions:

  • A comprehensive understanding of 5-HT receptor and autoreceptor expression patterns is essential for advancing therapeutic strategies for cognitive and mood disorders.
  • Further research into the specific expression and function of 5-HT receptors on distinct circuits will enhance our comprehension of the 5-HT system.
  • Developing novel approaches to profile 5-HT receptor expression will reveal more about the 5-HT controls of CNS neurochemical systems.
