Opioid Analgesics: Synthetic and Semisynthetic Opioids01:15

Opioid Analgesics: Synthetic and Semisynthetic Opioids

1.1K
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: Overview01:22

Opioid Receptors: Overview

4.4K
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,...

Knee Joint01:23

Knee Joint

3.2K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Opioid Analgesics: Morphine and Other Natural Cogeners

1.0K
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

685
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...

Structure of Lipids03:38

Structure of Lipids

98.9K
Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon-carbon or carbon-hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic...

Summary
This summary is machine-generated.

Most patients require few opioid pills after knee arthroscopy, with a median of 7. Meniscal repair, smoking, and prior opioid use predict higher consumption, aiding responsible prescribing.

Area of Science:

  • Orthopedic Surgery
  • Pain Management
  • Pharmacology

Background:

  • The opioid epidemic necessitates responsible prescribing practices.
  • Surgeons lack guidance for postoperative opioid decisions.
  • Knee arthroscopy patients' opioid use is not well-characterized.

Purpose of the Study:

  • To assess opioid consumption following knee arthroscopy.
  • To identify preoperative predictors of increased opioid usage.

Main Methods:

  • Prospective observational study of 221 knee arthroscopy patients.
  • Daily opioid consumption recorded in postoperative diaries.
  • Preoperative factors analyzed for association with opioid use.

Main Results:

  • Median opioid consumption was 7 pills; 81% used ≤20 pills.
  • 56% discontinued opioids by postoperative day 3.
  • Meniscal repair, smoking, and preoperative opioid use predicted higher consumption.

Conclusions:

  • Median postoperative opioid need after knee arthroscopy is low.
  • Meniscal repair, smoking, and prior opioid use are key predictors of higher consumption.
  • Findings can inform evidence-based opioid prescribing guidelines.
