What is Demerol?

Meperidine or pethidine, better known by the brand name Demerol ® or Dolantina® is a narcotic analgesic that acts as central nervous system depressant used to relieve medium or high intensity pain.

Meperidine belongs to the synthetic opioid group, in which can also be found methadone. Like other opioids, it causes dependency and withdrawal symptoms if you stop taking it abruptly after several days of administration, since the dose should gradually withdraw from.

It has the unique property among the opioids, to produce a blockade of ion channels, in this way also provides analgesia through a local anesthetic mechanism.
