概括

这项研究发现,氧化/纳洛组合对急性脊柱疼痛没有效果,即使在合规患者中也是如此. 结果表明,避免这种组合,以缓解急性背部和部疼痛.

科学领域:

疼痛管理疼痛管理
药理学药理学是指药理学的学科.
临床试验临床试验

背景情况:

之前的一项试验表明,氧化/纳洛对急性脊柱疼痛无效.
在最初的试验中,参与者的遵守程度较低,需要进一步分析.
这项研究侧重于符合条件的参与者之间的治疗疗效.

研究的目的:

为了估计 oxycodone/naloxone 的治疗疗效,在符合条件的急性脊柱疼痛患者中.
重新评估氧化/纳洛的有效性,排除不符合标准的个体.

主要方法:

使用倾向权重,联合建模和倾向匹配,进行了更合规的平均因果效应分析.
使用各种截止点 (处方剂量的≥20%至≥80%) 定义了合规性.
主要结局是第6周的疼痛严重程度;次要结局包括其他时间点的疼痛. 此外,还进行了每个协议的分析.

主要成果:

倾向权重显示了在第6周疼痛严重程度上偏好安慰剂的小但显著的差异 (P=0.006).
使用不同的方法,遵守截止点和时间点的分析要么有利于安慰剂,要么没有显著差异.
敏感性分析证实了缺乏疗效.

结论:

氧化/纳洛联合治疗急性脊柱疼痛是无效的,即使在接受治疗.
结果与最初的试验一致,不支持使用这种组合治疗急性脊柱疼痛.
有证据表明,在治疗急性背部和部疼痛时,应避免使用氧化/纳洛.

Opioid Analgesics: Synthetic and Semisynthetic Opioids

892

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

1.5K

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

818

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...

Local Anesthetics: Clinical Application as Epidural Anesthesia

674

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Local Anesthetics: Clinical Application as Spinal Anesthesia

1.3K

Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Opioid Receptors: Overview

3.9K

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,...
