Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

199
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

94
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Pharmacovigilance01:19

Pharmacovigilance

916
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Drug Abuse and Addiction: Pharmacological Phenomena

574
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...

Drug Administration and Therapy Phases: Overview01:26

Drug Administration and Therapy Phases: Overview

564
Drugs, the chemical agents used in diagnosing, treating, or preventing diseases, undergo a four-phase process of development: pharmaceutic, pharmacokinetics, pharmacodynamics, and therapeutic.
The pharmaceutical phase focuses on leveraging the physicochemical properties of the drug to design and manufacture an effective product. Variants include orally administered tablets or capsules, topical creams or ointments, and parenteral-delivery solutions or emulsions.
The pharmacokinetic phase...

Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

187
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Summary

Drug and polysubstance pre-loading before entering nightlife venues is under-researched. This scoping review highlights the vulnerability of individuals who drug pre-load and suggests intervention points for field-based researchers.

Area of Science:

  • Public Health
  • Substance Use Research
  • Nightlife Safety

Background:

  • Nighttime entertainment districts see individuals consuming alcohol and other substances prior to entry.
  • Existing research on alcohol pre-loading is extensive, but drug and polysubstance pre-loading remains under-investigated.
  • This practice poses significant harms and dangers to individuals.

Purpose of the Study:

  • To systematically map the literature on drug and polysubstance pre-loading.
  • To evaluate methodological approaches in field-based research on pre-loading.
  • To identify knowledge gaps and inform future research and interventions.

Main Methods:

  • A comprehensive scoping review following PRISMA (ScR) guidelines.
  • Searches conducted across eight major academic databases (Medline, PsycINFO, Embase, Scopus, CINAHL, Social Services Abstracts, Sociological Abstracts, Web of Science).
  • Author and citation analysis of relevant articles, followed by thematic analysis of nine included studies.

Main Results:

  • Identified drug pre-loading as a behavior linked to significant population vulnerability.
  • Proposed that point-of-entry research designs are more sensitive than portal-in designs.
  • Highlighted specific time points for potential field-based researcher interventions.

Conclusions:

  • Clinicians should assess pre-loading behaviors in young adults due to high prevalence and associated risks.
  • Further field-based research is crucial to understand the scope and dangers of pre-loading.
  • Intervention strategies can be developed based on identified vulnerabilities and research opportunities.
