CNS Depressants: Alcohol and Nicotine01:27

CNS Depressants: Alcohol and Nicotine

Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...
Dosage Regimens: Designs and Approaches01:28

Dosage Regimens: Designs and Approaches

Designing a dosage regimen, which refers to the manner of drug administration, is a complex process involving the selection of drug dose, route, and frequency. This process is underpinned by pharmacokinetic parameters derived from tests and population averages. These parameters are then tailored to patient-specific variables such as diagnosis, demographics, and allergy status. Once therapy commences, therapeutic response monitoring is critical and achieved through clinical and physical...

Drug Abuse and Addiction: Pharmacological Phenomena

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 necessarily...
Community Based Intervention01:30

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.
Foundations of Community Mental Health Programs
Central to the success of community-based interventions is the...

Area of Science:

  • Public Health
  • Digital Health
  • Substance Abuse Research

Background:

  • Growing availability of online programs for alcohol problems.
  • Need for systematic review of evidence for these interventions.

Purpose of the Study:

  • To review the efficacy of internet-based interventions for alcohol misuse.
  • To identify and synthesize findings from randomized controlled trials (RCTs).

Main Methods:

  • Systematic search of major databases (Medline, PsycINFO, Web of Science, Scopus) from 1998 onwards.
  • Inclusion criteria: internet-delivered intervention, focus on alcohol consumption, RCT design.
  • Extracted data on effect sizes for alcohol units and blood alcohol concentration (BAC).

Main Results:

  • 17 RCTs met inclusion criteria; 12 focused on university students, 11 on at-risk drinkers.
  • Effect sizes for alcohol units per week/month ranged from 0.02 to 0.81 (mean 0.42).
  • Effect sizes for peak BAC ranged from 0.22 to 0.88 (mean 0.66).

Conclusions:

  • Online alcohol interventions show potential benefits, especially for underrepresented groups.
  • Caution is advised due to limited studies, outcome heterogeneity, and student-centric samples.
  • Further RCTs in community samples are needed to establish efficacy and optimal delivery.
