Cardiac Arrest Following Drug Abuse with Intravenous Tapentadol: Case Report and Literature Review.
BACKGROUND Tapentadol is a centrally acting opioid analgesic, with a dual mode of action, as a norepinephrine reuptake inhibitor and an agonist of the μ-opioid receptor (MOR). Tapentadol is used for the management of musculoskeletal pain, and neuropathic pain associated with diabetic peripheral neuropathy. CASE REPORT A 32-year-old woman attended hospital for evaluation of an intractable headache. ⋯ Autopsy toxicology revealed significantly elevated levels of tapentadol, and bedside evidence suggested that the patient had self-administered this medication intravenously before her death. CONCLUSIONS We report a rare adverse effect of tapentadol causing respiratory depression leading to cardiac arrest. Medical examiners and forensic toxicologists should be aware of the toxicity of this novel opiate drug.
