Insights

Morphine shows protective effects against myocardial injury from ischemia-reperfusion and heart failure in animal models. It also benefits patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention.

Area of Science:

  • Cardiology
  • Pharmacology
  • Biomedical Science

Background:

  • Coronary heart disease (CHD) is a leading cause of death globally.
  • Myocardial injury from ischemia-reperfusion underlies heart failure in CHD.
  • Morphine, an opioid agonist, is used for pain relief and has shown potential in cardiovascular conditions.

Purpose of the Study:

  • To review the cardioprotective effects of morphine.
  • To examine morphine's impact on myocardial ischemia-reperfusion injury and heart failure models.
  • To assess morphine's role in ST-segment elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI).

Main Methods:

  • Literature review of studies on morphine's effects in animal models of myocardial ischemia-reperfusion and heart failure.
  • Analysis of clinical data on STEMI patients receiving morphine before or during PCI.
  • Brief description of relevant signaling pathways.

Main Results:

  • Morphine demonstrates protective effects in animal models of myocardial ischemia-reperfusion and chronic heart failure.
  • Morphine administration shows positive effects in STEMI patients undergoing pre-primary percutaneous coronary intervention (pre-PPCI) or PPCI.
  • Involvement of specific signaling pathways in morphine's cardioprotection is noted.

Conclusions:

  • Morphine exhibits significant cardioprotective properties against ischemia-reperfusion injury and heart failure.
  • Morphine may be a beneficial adjunct therapy for STEMI patients undergoing PCI.
  • Further research into morphine's mechanisms and clinical applications in cardiovascular disease is warranted.

Opioid Analgesics: Morphine and Other Natural Cogeners

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 Analgesics: Synthetic and Semisynthetic Opioids

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

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,...

Cardiopulmonary Resuscitation IV: Pharmacological Management

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...
