Transdermal fentanyl: acute analgesic clinical studies
Journal of Pain and Symptom Management
|April 1, 1992
Summary
Transdermal therapeutic systems (TTS) with fentanyl offer effective postoperative pain management for up to three days. While generally safe, some patients may need supplemental analgesia and experience side effects like nausea.
Area of Science:
- Pharmacology
- Anesthesiology
- Drug Delivery Systems
Background:
- Transdermal therapeutic systems (TTS) offer continuous drug delivery, mimicking intravenous infusions.
- Fentanyl, a potent synthetic opioid, is suitable for transdermal delivery due to its lipid solubility.
Purpose of the Study:
- To evaluate the analgesic efficacy of fentanyl TTS in postoperative patients.
- To assess the incidence of adverse effects associated with fentanyl TTS.
Main Methods:
- Preliminary clinical trials involving postoperative patients.
- Application of fentanyl TTS patches preoperatively (2 hours prior).
- Monitoring of pain levels and side effects (pruritus, nausea, vomiting, respiratory depression).
Main Results:
- Fentanyl TTS provided moderate-to-good analgesia for up to 3 days across various surgical procedures.
- Most patients required supplementary systemic opioids, particularly within the first 24 hours.
- Nausea and vomiting occurred in up to 70% of patients; clinically significant respiratory depression was rare.
Conclusions:
- Fentanyl TTS is a practical and effective method for managing postoperative pain.
- The system demonstrates utility in providing sustained analgesia, though supplemental pain relief may be necessary.
- Adverse event monitoring is crucial, with nausea/vomiting being the most frequent side effect.

01:11Clinical Trials: Overview
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
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...

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...
01:15Opioid 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...
01:24Parenteral Anesthetics: Overview
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
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...
