Failure of Intravenous Morphine to Serve as an Effective Instrumental Reinforcer in Dopamine D2 Receptor Knock-Out Mice [PDF]

, 2002
The rewarding effects of opiates are thought to be mediated through dopaminergic mechanisms in the ventral tegmental area, dopamine-independent mechanisms in the nucleus accumbens, or both. The purpose of the present study was to explore the contribution

Opioid Receptors in Immune and Glial Cells-Implications for Pain Control [PDF]

, 2020
Opioid receptors comprise μ (MOP), δ (DOP), κ (KOP), and nociceptin/orphanin FQ (NOP) receptors. Opioids are agonists of MOP, DOP, and KOP receptors, whereas nociceptin/orphanin FQ (N/OFQ) is an agonist of NOP receptors.

The Effect of Memantine on the Expression of Dopamine Receptors in the Striatum of Male Rats With Morphine Addiction [PDF]

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2023
Background and Objectives: Studies have indicated that the chronic use of morphine can result in physical and psychological dependence. Morphine dependence is associated with several cellular and molecular alterations in the mesocorticolimbic system, and

Amniotic-Fluid Ingestion Enhances the Central\ud Analgesic Effect of Morphine [PDF]

, 1991
Amniotic fluid and placenta contain a substance (POEF) that when ingested enhances opioid-mediated analgesia produced by several agents (morphine injection, vaginal/cervical stimulation, late pregnancy, footshock), but not that produced by aspirin ...

Beyond the label: Rethinking off‐label drug use in paediatrics. Towards a scientifically grounded and safer future for paediatric pharmacotherapy

British Journal of Clinical Pharmacology, EarlyView.
Abstract Despite regulatory progress being made in the past two decades, off‐label drug use in paediatrics remains pervasive, with prevalence estimated between 3% and 97% of prescriptions across different clinical settings. Off‐label use—defined as prescribing outside the conditions described in the Summary of Product Characteristics (SmPC)—is often ...

The effect of cannabinoid type 2 receptor agonist on morphine tolerance

IBRO Neuroscience Reports
Pain highly impacts the quality of life of patients. Morphine is used for pain treatment; however, its side effects, especially morphine tolerance, limit its use in the clinic. The problem of morphine tolerance has plagued health workers and patients for

Morphine Binds Creatine Kinase B and Inhibits Its Activity

Frontiers in Cellular Neuroscience, 2018
Morphine is an analgesic alkaloid used to relieve severe pain, and irreversible binding of morphine to specific unknown proteins has been previously observed.

Ingested bovine amniotic fluid enhances morphine antinociception in rats [PDF]

, 2000
Ingestion by rats of rat placenta or amniotic fluid enhances opioid-mediated, or partly opioid-mediated, antinociception produced by morphine injection, vaginal or cervical stimulation, late pregnancy, and foot shock.

Mapping opioid exposure through prescription data and postmortem analysis of opioid drugs in multiple tissues

British Journal of Clinical Pharmacology, EarlyView.
Background and Purpose Although opioids are central to end of life (EoL) care, tissue‐level opioid exposure remains poorly understood. The objective of this study was to characterize the relationship between prescription‐derived morphine equivalent daily dose (MEDD) and measured morphine concentrations across multiple organs.
