Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists01:23

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

429
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

385
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

647
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

121.9K
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.

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists01:27

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

340
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Sedatives and Hypnotics Drugs: Miscellaneous Agents

253
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Area of Science:

  • Pharmacology
  • Clinical Toxicology
  • Critical Care Medicine

Background:

  • Serotonin syndrome is a potentially fatal adverse drug reaction.
  • It arises from excessive serotonergic agonism, often due to drug interactions or overdose.
  • Key features include altered mental state, autonomic hyperactivity, and neuromuscular abnormalities.

Purpose of the Study:

  • To outline the clinical presentation and management of serotonin syndrome.
  • To emphasize the importance of recognizing syndrome severity for appropriate care.
  • To detail urgent interventions for severe cases, including hyperthermia.

Main Methods:

  • Clinical assessment of patient presentation and features.
  • Evaluation of symptom severity for management decisions.
  • Application of established treatment protocols for hyperthermia and critical symptoms.

Main Results:

  • Serotonin syndrome presents with a variable triad of symptoms.
  • Clinical severity dictates the level of care required, with severe cases needing high-dependency units.
  • Hyperthermia (temperature >38.5°C) necessitates immediate cooling and sedation, potentially progressing to intubation.

Conclusions:

  • Early recognition and clinical assessment of serotonin syndrome are vital.
  • Management should be tailored to symptom severity, escalating care as needed.
  • Prompt intervention for hyperthermia is critical to prevent severe complications and mortality.
