Antidepressant Drugs: MAOIs and Other Agents01:23

Antidepressant Drugs: MAOIs and Other Agents

378
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

418
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

625
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...

CNS Stimulants: Psychedelic Agents

256
Hallucinogens, also known as psychedelic drugs, are a class of substances known for their ability to alter perception, cognition, and emotions. Despite their profound effects on the mind, these drugs are non-addictive, setting them apart from many other abused substances. The mechanism of action of these drugs lies in their impact on the 5-HT2A receptor in the brain. Upon activation, this receptor couples to Gq-type G proteins, triggering a cascade that releases intracellular calcium. This...

Neurotransmitters

1.5K
Neurotransmitters are essential chemical messengers within the nervous system, facilitating the communication between neurons. These chemical messengers, varying in function and effect, are critical for sustaining various aspects of neurological health and emotional well-being.

Hallucinogens and Psychedelics01:27

Hallucinogens and Psychedelics

292
Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.
Marijuana, derived from the dried leaves and flowers of the hemp plant, contains...

Area of Science:

  • Neuroscience
  • Immunology
  • Pharmacology

Background:

  • Psychedelics are known for behavioral effects, with research focused on brain 5-HT2A receptors.
  • 5-HT2A receptors are widely distributed, influencing immune function alongside serotonin.
  • Serotonin at 5-HT2A receptors typically promotes inflammation, increasing cytokines and immune cell activity.

Purpose of the Study:

  • To review serotonergic modulation of immune function.
  • To explore the role of 5-HT2A receptors in immunity.
  • To summarize psychedelic anti-inflammatory and immunomodulatory effects.

Main Methods:

  • Literature review of preclinical and clinical studies.
  • Analysis of serotonergic pathways in immune regulation.
  • Examination of 5-HT2A receptor activation by psychedelics.

Main Results:

  • Some psychedelics exhibit potent anti-inflammatory effects via 5-HT2A receptor activation.
  • Preclinical models and human inflammatory disease studies show promise.
  • Limited human data suggests potential therapeutic applications.

Conclusions:

  • Psychedelics may represent a novel therapeutic avenue for inflammatory conditions.
  • Further human studies are needed to validate anti-inflammatory properties.
  • Understanding 5-HT2A receptor roles in immunity is crucial for psychedelic research.
