Pethidine

Pethidine (pronounced: peth-i-deen), also known as meperidine in the United States, is a synthetic opioid of the phenylpiperidine class. It is used to treat moderate to severe pain, and can also be used for anesthesia and as a preoperative medication to counteract postoperative pain.

Etymology

The term "Pethidine" is derived from the Greek words "petho" (to fall) and "idine" (pertaining to), referring to the drug's ability to alleviate pain.

Usage

Pethidine is primarily used in the treatment of pain. It is also used in anesthesia to induce sleep before surgery and to provide pain relief after surgery. Pethidine can also be used to treat severe pain in obstetrics, particularly during labor.

Pharmacology

Pethidine works by binding to the mu-opioid receptor in the brain, which results in a decrease in the perception of pain. It is a central nervous system depressant, which means it can slow brain activity and cause drowsiness.

Side Effects

Common side effects of pethidine include drowsiness, dizziness, and nausea. More serious side effects can include respiratory depression, low blood pressure, and addiction.
