Ten healthy male subjects received diazepam (10 or 20 mg), fentanyl (0.1 or 0.2 mg) or a placebo intravenously at weekly intervals according to a latin square design. They were tested on a battery of psychological and electroencephalographic tests at 0.5, 2, 6, and 8 hrs following injection. Fentanyl had little effect on memory while diazepam reduced the ability to learn without increasing forgetting of material alread acquired. By the 2nd hour post injection, only the low dose of fentanyl had no residual effect. Recovery was complete by the 6th hour for all treatments according to the psychological tests except for the lagging effect of high dose of diazepam on memory. The electroencephalographic effects of diazepam persisted beyond the end of the testing sessions while those of the high dose of fentanyl recovered by the 8th hour. Thus in the dosages tested, diazepam had more intense and prolonged effects than fentanyl.

Fentanyl is a potent opioid analgesic marketed for the treatment of stable intense chronic pain, particularly in the form of a transdermal patch. These delivery devices carry the same risk of adverse effects and drug interactions as conventional formulations of opioids. The patches carry an added risk of fentanyl overdose because they contain very high doses, both before and after use. High-risk situations for overdose were identified by examining the results of pharmacovigilance studies and medication error prevention programmes, as well as an observational study, case reports, and a French legal action. The main situations exposing patients to a risk of overdose are: confusion between two dose strengths, forgetting to remove the patch; accidental transfer of the patch to another person, application of more than one patch, cutting the patches, self-medication, and ingestion. Increased skin temperature facilitates fentanyl absorption and thus increases the risk of overdose; high-risk situations include fever, electric blankets, and intense physical exercise. In practice, the precautions for treatment and patch disposal must be followed exactly if this delivery system is to serve as a valid alternative to morphine for selected patients with stable intense chronic pain.
