Antidepressant Drugs: MAOIs and Other Agents01:23

Antidepressant Drugs: MAOIs and Other Agents

476
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...

Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs

795
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...

Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

7.5K
Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

G-protein Coupled Receptors01:21

G-protein Coupled Receptors

125.1K
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 GI Tract Motility: Serotonin Receptor Agonists

505
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: Overview01:25

Antidepressant Drugs: Overview

928
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...

Summary
This summary is machine-generated.

Selective serotonin reuptake inhibitors (SSRIs) can cause persistent sexual dysfunction. This study proposes that bioelectric memory in cells maintains these long-term SSRI side effects, offering potential new treatments.

Area of Science:

  • Neuroscience
  • Cell Biology
  • Pharmacology

Background:

  • Selective serotonin reuptake inhibitors (SSRIs) are widely prescribed antidepressants.
  • A significant side effect is persistent sexual dysfunction, even after drug discontinuation.
  • The underlying mechanism for this long-lasting effect remains poorly understood.

Purpose of the Study:

  • To investigate the potential mechanism behind persistent sexual dysfunction caused by SSRIs.
  • To explore the role of bioelectric alterations in maintaining long-term physiological changes.
  • To present novel findings in a model organism and link neurotransmitter signaling to developmental bioelectrics.

Main Methods:

  • Review of clinical data on SSRI-induced sexual dysfunction.
  • Experimental exposure of planarian flatworms to SSRIs.
  • Measurement of changes in cellular resting potential and bioelectric properties.

Main Results:

  • Brief SSRI exposure induced long-lasting changes in the resting potential profile of planarian cells.
  • This suggests that bioelectric circuits can maintain altered cellular properties.
  • Evidence links neurotransmitter signaling to developmental bioelectrics.

Conclusions:

  • Cellular bioelectric memory may explain persistent SSRI side effects.
  • Understanding tissue bioelectric memory could lead to new therapeutic strategies.
  • Ionoceutical interventions may counteract SSRI-related adverse effects.
