Meperidine is a synthetic narcotic analgesic that acts on the central nervous system by a mechanism that is similar to morphine, although with a shorter duration of action. Meperidine has approximately one-tenth the potency of morphine and tolerance to meperidine develops more slowly. It is used to treat moderate to severe pain, producing clinical effects of analgesia, sedation, euphoria, and respiratory depression.
Administration: Tablet, liquid
Elimination: Meperidine is metabolized in the liver to normeperidine and meperidinic acid.
Abuse Potential: Meperidine has the potential for abuse and diversion and can be habit-forming. Physical dependence and tolerance may develop upon repeated administration. Like other narcotics meperidine is subject to the provisions of the federal narcotic laws.
