Opioid Analgesics: Synthetic and Semisynthetic Opioids01:15

Opioid Analgesics: Synthetic and Semisynthetic Opioids

264
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 Analgesics: Morphine and Other Natural Cogeners

213
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...

Analgesia and Pain Management01:25

Analgesia and Pain Management

560
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

459
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...

Factors Affecting Drug Response: Overview

1.9K
When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

Desensitization and Tachyphylaxis01:20

Desensitization and Tachyphylaxis

1.6K
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.

Area of Science:

  • Forensic Toxicology
  • Public Health
  • Epidemiology

Background:

  • Opioid abuse is a major global cause of drug-related illness and death.
  • Previous research suggested an increasing age of opiate users in Australia.

Purpose of the Study:

  • To investigate the demographic trends of lethal opioid overdose cases in South Australia.
  • To determine if the age of individuals experiencing fatal opioid overdoses has risen over time.

Main Methods:

  • Analysis of toxicology and pathology case files from Forensic Science SA, Adelaide.
  • Inclusion of all cases with lethal opioid levels between 2000 and 2019 (n=499).
  • Statistical analysis to assess changes in median age and age group distribution over the study period.

Main Results:

  • The median age of opioid overdose deaths significantly increased by approximately 16 years (p=0.007).
  • A significant rise in total deaths was observed in the 45-54 and 55-64 age groups (p=0.009 and p<0.001, respectively).
  • Heroin overdose cases had the lowest median age (39 years), while tramadol toxicity cases had the highest (50.5 years).

Conclusions:

  • The demographic profile of fatal opioid overdose cases in South Australia shows a clear trend towards an aging population.
  • Forensic and clinical practitioners must recognize the increasing risk of opioid abuse in older adults.
  • This trend may worsen existing age-related chronic diseases and contribute to fatalities in this demographic.
