Psychosis and Antipsychotic Drugs: Overview

931
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...

Antipsychotic Drugs: Therapeutic Uses and Side Effects

857
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...

Organic Compounds

57.6K
All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and synthetic compounds that contain carbon. Although a single, precise definition has yet to be identified by the chemistry community, most agree that a defining trait of organic molecules is the presence of carbon as the principal element, bonded to hydrogen and other carbon atoms. However, some carbon-containing compounds such as carbonates, cyanides, and...

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...

Antipsychotic Drugs: Typical and Atypical Agents01:21

Antipsychotic Drugs: Typical and Atypical Agents

920
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...

Area of Science:

  • Neuroscience
  • Pharmacology
  • Zebrafish models

Background:

  • Psychiatric drugs often target multiple sites, necessitating broad screening.
  • Identifying multitarget compounds like antipsychotics requires sophisticated assays.
  • Zebrafish behavior is a promising tool for neuroactive compound screening.

Purpose of the Study:

  • To develop a battery of behavioral assays in larval zebrafish.
  • To assess if behavioral profiles can identify and classify psychiatric drugs.
  • To determine the necessary behavioral assays for multitarget compound discovery.

Main Methods:

  • Developed a comprehensive suite of behavioral assays for larval zebrafish.
  • Utilized the antipsychotic drug haloperidol as a model compound.
  • Screened previously uncharacterized compounds based on behavioral profiles.

Main Results:

  • Established that zebrafish behavioral profiles can identify psychiatric drugs.
  • Demonstrated the ability to detect compounds with antipsychotic-like activity.
  • Confirmed that behavioral phenotyping can reveal multitarget mechanisms of action.

Conclusions:

  • Larval zebrafish behavioral assays offer sufficient phenotypic resolution for psychiatric drug discovery.
  • This approach can identify novel compounds with desired therapeutic actions and mechanisms.
  • Behavioral profiling in zebrafish provides a viable strategy for discovering multitarget psychiatric medications.
