Opioid Analgesics: Synthetic and Semisynthetic Opioids

1.4K
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...

Analgesia and Pain Management

2.8K
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...

Opioid Analgesics: Morphine and Other Natural Cogeners

1.4K
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...

Opioid Receptors: Overview01:22

Opioid Receptors: Overview

6.2K
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,...

Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents

847
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...

Pharmaceutical Poisoning: Potential Scenarios

74
Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...

Summary

Liposomal bupivacaine significantly reduced opioid adverse events like urinary retention and respiratory depression in surgical patients. This also led to fewer high-risk fallers, enhancing patient safety and potentially lowering hospitalization costs.

Area of Science:

  • Anesthesiology
  • Surgical Pain Management
  • Pharmacology

Background:

  • Opioids are standard for postoperative pain but cause adverse events (respiratory depression, nausea, falls).
  • Extended-release liposomal bupivacaine is an alternative for multimodal pain management.
  • This study evaluated liposomal bupivacaine's impact on opioid-related adverse events in specific surgeries.

Purpose of the Study:

  • To assess the effect of liposomal bupivacaine on postoperative opioid adverse events.
  • To analyze outcomes following open hernia repair and laparoscopic colon resection.

Main Methods:

  • Retrospective analysis of 82 patients undergoing open hernia repair or laparoscopic colon resection.
  • Comparison between 45 patients treated with liposomal bupivacaine and historical controls.
  • Adverse opioid events (constipation, respiratory depression, falls) were measured.

Main Results:

  • Liposomal bupivacaine significantly reduced urinary retention and respiratory depression (p<0.05).
  • High-risk fall patients decreased from 16% to 8.4%.
  • Low-risk fall patients increased from 37.6% to 48.7%.

Conclusions:

  • Liposomal bupivacaine use correlates with reduced urinary retention, respiratory depression, and fall risk.
  • These findings suggest liposomal bupivacaine can mitigate opioid complications in postsurgical pain management.
  • Reduced complications may lead to decreased hospitalization costs, especially post-2014 healthcare reforms.
