- 阿片类药物依赖和戒断在成治疗中存在重大挑战.
- 负基调制剂 (NAM) 为受体调制提供了有针对性的方法.
研究的目的:
- 在小鼠模型中评估Org27569 CB1R NAM在缓解急性和持续性阿片类药物戒断症状方面的疗效.
- 评估Org27569对在氧化依赖后的纳洛沉和持续性戒断行为的影响.
主要方法:
- 通过不断增加的腹腔内剂量,使小鼠依赖于氧化.
- Org27569在不同剂量下进行了治疗,以评估其对纳洛催发性戒断行为的影响,包括跳跃和有条件的地方厌恶.
- 长期戒断通过行为测试来评估类似焦虑和社会行为的行为,以及在一项新型测试中逃避行为的行为.
主要成果:
- Org27569在较高剂量下降了阿片类药物戒断引起的跳跃,但这些效应被运动能力下降所混.
- 在没有影响运动的剂量下,Org27569并没有缓解因戒断引起的跳跃,有条件的地点厌恶或逃跑行为.
- 在所有测试剂量中,org27569对胃肠机动性表现出适度的抑制作用.
结论:
- 对阿片类药物戒断症状的Org27569的治疗潜力是有限的,这是由于对运动和非特异性胃肠道影响的混作用.
- 需要使用表现出更强大的长期戒断综合征的模型进行进一步的研究,以充分评估CB1R NAM疗效.

Opioid Receptors: Overview
761
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,...

Opioid Analgesics: Synthetic and Semisynthetic Opioids
287
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
585
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
242
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
193
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...

CNS Depressants: Alcohol and Nicotine
205
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...
