Desensitization and Tachyphylaxis01:20

Desensitization and Tachyphylaxis

1.7K
Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.

Drug Abuse and Addiction: Pharmacological Phenomena

463
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Adrenergic Agonists: Indirect-Acting Agents

1.6K
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...

CNS Stimulants: Psychedelic Agents

142
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...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

566
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Altered States of Awareness01:06

Altered States of Awareness

174
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...

Area of Science:

  • Neuroscience
  • Psychopharmacology
  • Psychiatry

Background:

  • Psychotomimetic drugs can paradoxically alleviate psychosis-related symptoms.
  • Symptoms like attention deficits, pain, and depression are linked to psychosis risk.

Purpose of the Study:

  • Introduce novel concepts: psychotomimetic compensation and psychotomimetic sensitization.
  • Explain the paradox of psychotomimetic drugs relieving psychosis risk symptoms.

Main Methods:

  • Theorize short-term drug/stressor effects (compensation) via neurotransmitter systems (endocannabinoid, serotonergic, glutamatergic, dopaminergic).
  • Describe long-term effects (sensitization) involving gradual intensification of psychotic-like experiences.

Main Results:

  • Psychotomimetic compensation: short-term relief of deficits via neurotransmitter engagement.
  • Psychotomimetic sensitization: long-term intensification of psychotic experiences with repeated exposure.
  • Model integrates drug effects with stress and psychosis risk.

Conclusions:

  • The proposed models offer a framework for understanding psychotomimetic drug actions.
  • Highlights theoretical and practical implications for psychosis research and treatment.
