Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

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: MAOIs and Other Agents

Antidepressant Drugs: MAOIs and Other Agents

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...

Nonlinear Pharmacokinetics: Dependence of Elimination Half-Life and Dose Clearance

Nonlinear Pharmacokinetics: Dependence of Elimination Half-Life and Dose Clearance

The elimination half-life and drug clearance of drugs following nonlinear kinetics can vary with dosage. The Michaelis-Menten parameters and drug concentration influence these factors. As the dose increases, the elimination half-life tends to lengthen, resulting in a reduction in clearance and a disproportionately larger area under the curve. The total clearance can be derived from the Michaelis-Menten equation for drugs following a one-compartment model.
A study on guinea pigs examined the...

Antidepressant Drugs: Overview

Antidepressant Drugs: Overview

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...

Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs

Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs

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...

Hepatic Encephalopathy

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...

Area of Science:

Hepatology
Molecular Biology
Pharmacology

Background:

Serotonin's role in liver physiology and pathology is increasingly recognized.
Platelet-derived serotonin is crucial for initiating liver regeneration post-hepatectomy.
Serotonin influences hepatic microcirculation and graft outcomes.

Purpose of the Study:

To explore the multifaceted roles of serotonin in liver regeneration and disease.
To investigate serotonin's impact on aged liver function and biliary tree repair.
To examine serotonin's involvement in various liver pathologies and its therapeutic potential.

Main Methods:

Rodent models of partial hepatectomy and liver injury.
Assessment of hepatic microcirculation and sinusoidal perfusion.
Analysis of signaling pathways including vascular endothelial growth factor.
Evaluation of serotonin's effects in conditions like ischemia/reperfusion injury, steatohepatitis, viral hepatitis, fibrosis, and cancer.

Main Results:

Serotonin promotes liver regeneration and improves outcomes in small-for-size grafts.
Serotonin receptor agonists enhance perfusion in aged livers and restore regeneration via VEGF.
Cholangiocytes utilize serotonin for biliary tree regeneration.
Serotonin contributes to steatohepatitis, viral hepatitis, fibrosis progression, and primary liver cancer growth.

Conclusions:

Serotonin acts as both a beneficial factor in liver regeneration and a detrimental factor in liver disease.
Serotonin's complex roles necessitate careful consideration for therapeutic strategies.
Targeting serotonin pathways presents a promising avenue for pharmacological intervention in liver disease.
