Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

1.0K
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...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

684
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...

Data Validation01:03

Data Validation

6.2K
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
Nursing assessment guides are generally based on holistic models rather than medical...

Drug Dependence01:17

Drug Dependence

1.5K
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Opioid Analgesics: Synthetic and Semisynthetic Opioids01:15

Opioid Analgesics: Synthetic and Semisynthetic Opioids

824
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

Area of Science:

  • Neuroscience
  • Psychology
  • Addiction Research

Background:

  • Drug cue reactivity (DCR) is a crucial element in understanding and treating substance use disorders.
  • Existing research lacks a validated database of pictorial cues specifically for methamphetamine and opioids.
  • Standardized stimuli are needed for consistent experimental assessment and intervention in DCR studies.

Purpose of the Study:

  • To develop and validate a comprehensive database of pictorial cues for methamphetamine and opioid use.
  • To create a standardized resource for researchers investigating drug cue reactivity.
  • To facilitate the development of effective DCR-based assessment and intervention strategies.

Main Methods:

  • Selection of 360 images across three groups: methamphetamine, opioid, and neutral (control), matched for content.
  • Participants (n=28) with a history of methamphetamine and opioid use rated images for craving, valence, and arousal.
  • Image sets were selected for fMRI tasks, with tasks made available online.

Main Results:

  • Drug-related images elicited significantly higher craving and arousal, and lower valence compared to neutral images.
  • No significant differences in craving, arousal, or valence were found between methamphetamine and opioid images.
  • Increased time spent viewing drug cues correlated positively with reported craving, with a 383 ms response time increase per 10 craving points.

Conclusions:

  • The Methamphetamine and Opioid Cue Database (MOCD) offers a validated resource for DCR research.
  • This database enables researchers to select equivalent image sets for multiple assessments and interventions.
  • The MOCD supports future experimental studies and the development of targeted therapeutic strategies for substance use disorders.
