Preclinical Development: Overview01:28

Preclinical Development: Overview

4.5K
Preclinical development consists of a series of tests that ensure the safety and efficacy of a new therapeutic compound before it is tested in humans. There are four main phases to this process. First, safety pharmacology tests are conducted to ensure the drug does not produce any acutely harmful effects. These tests examine parameters such as bronchoconstriction, cardiac dysrhythmias, blood pressure changes, and ataxia. Next, preliminary toxicological testing is performed to determine the...

CNS Stimulants: Psychedelic Agents

160
Hallucinogens, also known as psychedelic drugs, are a class of substances known for their ability to alter perception, cognition, and emotions. Despite their profound effects on the mind, these drugs are non-addictive, setting them apart from many other abused substances. The mechanism of action of these drugs lies in their impact on the 5-HT2A receptor in the brain. Upon activation, this receptor couples to Gq-type G proteins, triggering a cascade that releases intracellular calcium. This...

Drug Discovery: Overview

8.0K
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

Psychosis: Goals of Pharmacotherapy

145
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Hallucinogens and Psychedelics01:27

Hallucinogens and Psychedelics

182
Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.
Marijuana, derived from the dried leaves and flowers of the hemp plant, contains...

An Overview of Psychoactive Drugs01:28

An Overview of Psychoactive Drugs

237
Psychoactive drugs impact brain function, influencing perception, mood, consciousness, cognition, and behavior. These substances are grouped based on their effects and the mechanisms by which they act.
Stimulants such as cocaine, amphetamines, and nicotine enhance brain activity, leading to increased alertness, attention, and energy. These drugs typically raise heart rate, blood pressure, and body temperature. While they can induce feelings of euphoria, their misuse can result in severe health...

Area of Science:

  • Neuroscience
  • Pharmacology
  • Psychiatry

Background:

  • Resurgent interest in psychedelics for treating PTSD, substance abuse, and depression.
  • Current research often overlooks non-psychological mechanisms of psychedelic action.
  • Psychedelics may exert therapeutic effects via multi-faceted physiological pathways.

Purpose of the Study:

  • To propose a framework for understanding the full range of psychedelic biological effects.
  • To explore potential therapeutic applications beyond psychiatric disorders.
  • To outline advantageous experimental approaches for future research.

Main Methods:

  • Review of existing literature on psychedelic mechanisms of action.
  • Emphasis on a multi-faceted approach combining in silico, in vitro, and in vivo modeling.
  • Exploration of physiological effects including brain networks, neuroplasticity, and the gut-brain axis.

Main Results:

  • Psychedelics may modulate brain activity, neuronal plasticity, neuroendocrine function, glial cells, epigenetics, and the gut-brain axis.
  • Potential applications extend to brain injuries (stroke, TBI) and neurodegenerative diseases (Parkinson's, Alzheimer's).
  • The gut-brain axis in psychiatric disorders is also a potential area for psychedelic intervention.

Conclusions:

  • A comprehensive understanding requires investigating both psychological and physiological mechanisms.
  • Integrated modeling approaches are crucial for elucidating psychedelic effects.
  • Novel therapeutic avenues for neurological and psychiatric conditions may be discovered.
