Antipsychotic Drugs: Typical and Atypical Agents01:21

Antipsychotic Drugs: Typical and Atypical Agents

Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...
Antipsychotic Drugs: Therapeutic Uses and Side Effects01:21

Antipsychotic Drugs: Therapeutic Uses and Side Effects

Antipsychotic drugs primarily block dopamine and serotonin receptors and cholinergic, adrenergic, and histaminergic receptors, thereby reducing hallucinations and delusions in conditions like schizophrenia. However, they can trigger unwanted extrapyramidal effects such as dystonias, Parkinson-like symptoms, and tardive dyskinesia.
Despite these side effects, antipsychotics are used therapeutically for various purposes, including managing schizophrenia, preventing nausea and vomiting, curbing...
Drugs Affecting Neurotransmitter Synthesis01:29

Drugs Affecting Neurotransmitter Synthesis

Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase, which converts...
Antidepressant Drugs: MAOIs and Other Agents01:23

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...
Drugs Affecting Neurotransmitter Release or Uptake01:21

Drugs Affecting Neurotransmitter Release or Uptake

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...
Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Summary

Some atypical antipsychotics may promote neurogenesis, the creation of new neurons, in the brain. This study investigates if this effect is common to all atypical antipsychotic drugs.

Area of Science:

  • Neuroscience
  • Pharmacology

Background:

  • Emerging evidence suggests certain atypical antipsychotics may stimulate neurogenesis.
  • Neurogenesis has been observed in brain regions like the hippocampus and frontal cortex.
  • Atypical antipsychotics represent a diverse class of medications.

Purpose of the Study:

  • To determine if neurogenesis is a class effect of all atypical antipsychotics.
  • To consolidate existing research on atypical antipsychotics and neurogenesis.

Main Methods:

  • A comprehensive literature search was conducted.
  • Studies investigating atypical antipsychotics and their impact on neurogenesis were systematically reviewed.

Main Results:

  • The literature search aimed to establish whether neurogenesis is a consistent effect across the atypical antipsychotic drug class.
  • Analysis focused on identifying studies reporting on neurogenesis in relation to various atypical antipsychotics.

Conclusions:

  • The findings will clarify whether the neurogenic effects of atypical antipsychotics are a shared characteristic or specific to certain agents.
  • This research provides a foundation for understanding the broader implications of atypical antipsychotics on brain plasticity.
