Phenoperidine is a narcotic analgesic used primarily for the relief of moderate to severe pain. It is a synthetic opioid derived from pethidine, and is structurally related to meperidine. Phenoperidine is usually administered orally, intramuscularly, or intravenously in the form of tablets, capsules, or an injectable solution. Common side effects include nausea, drowsiness, dizziness, and constipation. More serious side effects include respiratory depression, hypotension, and loss of consciousness.
Phenoperidine is an opioid analgesic, structurally related to pethidine (also known as meperidine or Demerol), that was historically used as a pain reliever and general anesthetic . It was first synthesized in 1
It is metabolized in the liver and eliminated through bile and urine. Due to its fast and prolonged analgesic effects, with minimal cardiac and respiratory depression, it was particularly useful in pediatric intensive care units [3].
However, due to its potential for abuse and dependence, similar to other opioid medications, phenoperidine is no longer widely used. Its exact regulatory status may vary by country, but it is not prescribed or recommended by major health organizations.
