Summary
Transdermal buprenorphine effectively managed central pain syndrome in a patient refractory to other treatments. This opioid alternative significantly reduced pain scores and improved daily function, offering a new therapeutic avenue.
Area of Science:
- Neurology
- Pharmacology
- Pain Management
Background:
- Central pain syndrome (CPS) presents a significant challenge in pain management due to limited effective treatment options.
- Conventional treatments including antiepileptics, antidepressants, and traditional opioids often yield insufficient analgesia or intolerable side effects.
Observation:
- A 53-year-old male with peripheral sensorimotor neuropathy developed severe central pain after an intracerebral hemorrhage, unresponsive to standard CPS therapies.
- Escalating doses of oral opioids and transdermal fentanyl failed to provide adequate pain relief and caused cognitive impairment.
Findings:
- Transdermal buprenorphine, administered in escalating doses, successfully controlled the patient's central pain, reducing Visual Analogue Scale scores from 8/10 to 2/10 or less.
- The patient experienced significant improvements in overall function and participation in daily activities.
- Buprenorphine's unique pharmacological profile, including NMDA receptor antagonism and K(ATP) channel activation, may explain its efficacy in refractory neuropathic pain.
Implications:
- Buprenorphine represents a promising alternative analgesic for managing central pain syndrome, particularly in cases resistant to other treatments.
- This case highlights the potential of buprenorphine in improving quality of life for patients with severe neuropathic pain and opioid-induced side effects.

01:15Opioid 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...
01:25Analgesia and Pain Management
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...
01:18Transdermal Drug Delivery Systems
Transdermal drug delivery systems (TDDS) enable the controlled release of drugs across the skin into systemic circulation. They are particularly advantageous for drugs with short half-lives or narrow therapeutic indices, as they maintain consistent plasma concentrations and reduce the risk of subtherapeutic or toxic levels.TDDS are categorized into monolithic, reservoir, and mixed systems. Monolithic systems embed the drug in a polymer matrix, where diffusion governs release. Reservoir systems...
01:22Opioid 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, D-Pen5]-enkephalin or DPDPE for...
01:29Drug Delivery: Parenteral Route
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

01:20Pain
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...
