Opioid Analgesics: Synthetic and Semisynthetic Opioids01:15

Opioid Analgesics: Synthetic and Semisynthetic Opioids

968
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...

Opioid Receptors: Overview

4.2K
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

Opioid Analgesics: Morphine and Other Natural Cogeners

901
Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...

Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents

649
Diarrhea, a condition marked by frequent loose or watery bowel movements, can be triggered by multiple factors such as viral or bacterial infections, food intolerances, anxiety, medications, and digestive disorders. Symptoms may include abdominal pain, bloating, nausea, and cramping. Severe or prolonged diarrhea can lead to complications like electrolyte imbalances, malnutrition, and dehydration if left untreated.
Opioids, widely used antidiarrheal agents, mitigate diarrhea by slowing down...

Drug Classes and Categories01:25

Drug Classes and Categories

3.1K
Drugs can be classified according to their chemical composition or their intended therapeutic application. For instance, anti-infective agents that possess the ability to eliminate pathogens or suppress their growth and reproduction can be grouped based on the organisms they target or their chemical structure. Furthermore, drugs can be divided into prescription, nonprescription, or controlled substances. Prescription medications, such as antibiotics, require oversight from a licensed healthcare...

Summary

Individuals with gambling disorder exhibit higher psychiatric comorbidity than those with opioid use disorder. Attention-deficit hyperactivity disorder (ADHD) is linked to increased psychiatric burden in both groups, necessitating tailored treatment approaches.

Area of Science:

  • Psychiatry
  • Addiction Medicine
  • Neurodevelopmental Disorders

Background:

  • Psychiatric comorbidities are common in substance use disorders and non-substance-related addictive disorders like gambling disorder.
  • The co-occurrence of substance use disorders and attention-deficit hyperactivity disorder (ADHD) is increasingly recognized.
  • Understanding comorbidity patterns is crucial for effective treatment of addictive disorders.

Purpose of the Study:

  • To identify distinct patterns of psychiatric comorbidity in patients with opioid use disorder (OMT) and problem gambling (PrG).
  • To examine the association between patient group (OMT vs. PrG) and ADHD status with these comorbidity patterns.
  • To investigate how demographic factors relate to class membership within identified comorbidity profiles.

Main Methods:

  • Latent class analysis (LCA) was employed to identify psychiatric comorbidity patterns.
  • Multinomial logistic regression was used to analyze associations between patient group, ADHD status, age, gender, and class membership.
  • Standardized instruments including the Mini International Neuropsychiatric Interview and Adult ADHD self-report scale were administered.

Main Results:

  • Three distinct classes of psychiatric comorbidity were identified.
  • Problem gambling patients were less likely to belong to the class with low comorbidity compared to OMT patients.
  • Individuals with childhood or adult ADHD were more likely to be in the most psychiatrically burdened class (Class 2).

Conclusions:

  • Problem gambling patients face a higher risk of psychiatric comorbidities than opioid maintenance treatment patients.
  • Attention-deficit hyperactivity disorder (ADHD) is significantly associated with increased psychiatric comorbidity burden.
  • Increased awareness and targeted interventions for psychiatric comorbidities in gambling disorder and ADHD populations are essential.
