Is the euphoric effect of Darvon is similar to morphine or not?

The euphoric effect of Darvon (propoxyphene) is generally considered to be less intense than that of morphine. While both are opioid analgesics, morphine produces stronger analgesic and euphoric effects due to its potency and direct action on opioid receptors in the brain. Darvon was often prescribed for mild to moderate pain, but its euphoric effects are milder and less sought after compared to morphine. Additionally, Darvon has been largely withdrawn from the market due to safety concerns and its association with serious side effects.
