Dextropropoxyphene is a mild opioid analgesic formerly used for the management of mild to moderate pain. It was also available in combination with other drugs such as paracetamol for pain relief. Due to concerns about toxicity, risk of overdose, and cardiac side effects, dextropropoxyphene has been withdrawn or banned in many countries and is no longer widely approved for medical use.
Pharmacokinetics
Reported pharmacokinetics in healthy adult volunteers following a single oral dose.
