Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs01:28

Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs

475
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...

Drugs Affecting Neurotransmitter Release or Uptake01:21

Drugs Affecting Neurotransmitter Release or Uptake

1.1K
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: MAOIs and Other Agents

288
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...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

296
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

G-protein Coupled Receptors01:21

G-protein Coupled Receptors

120.6K
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.

Adrenergic Agonists: Indirect-Acting Agents01:25

Adrenergic Agonists: Indirect-Acting Agents

1.7K
Indirect-acting adrenergic agonists potentiate the effects of endogenous catecholamines through different mechanisms without directly binding to adrenoceptors.
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral...

Area of Science:

  • Neuroscience
  • Pharmacology
  • Psychiatry

Background:

  • Amphetamines (e.g., AMPH, METH, MDMA) are widely abused psychotropic substances.
  • Amphetamine abuse can lead to neuroinflammation, neurotoxicity, and neuropsychiatric disorders, notably depression.
  • Transient receptor potential (TRP) channels, particularly TRPC channels, are implicated in neurological diseases, but their role in amphetamine-induced depression is unclear.

Purpose of the Study:

  • To elaborate on the pathophysiological mechanisms of depression induced by amphetamine abuse.
  • To review the functions of TRPC channels in the nervous system.
  • To explore the potential correlation between TRPC channels and amphetamine abuse-induced depression.

Main Methods:

  • Literature review of existing studies on amphetamine abuse, depression, and TRPC channels.
  • Analysis of neurobiological pathways involved in amphetamine neurotoxicity.
  • Synthesis of current knowledge on TRPC channel function in neurological systems.

Main Results:

  • Amphetamine abuse damages dopaminergic and serotonin neurons, causing neuroinflammation and neurotoxicity.
  • Depression is a common neuropsychiatric disorder associated with amphetamine abuse.
  • TRPC channels regulate Ca2+ homeostasis and are linked to neurological diseases, suggesting a potential role in amphetamine-induced depression.

Conclusions:

  • Understanding the link between TRPC channels and amphetamine-induced depression is crucial.
  • This review provides a theoretical basis for developing novel therapeutic drugs.
  • Targeting TRPC channels may offer a new strategy for treating amphetamine abuse-induced depression.
