What is the duration of action for IM meperidine?

The duration of action for intramuscular (IM) meperidine, also known as pethidine, is typically around 2 to 4 hours. This length of time corresponds with how the drug is metabolized and eliminated from the body. Meperidine is a short-acting opioid analgesic, and its effects generally last within this range, making it suitable for managing moderate pain during a controlled environment, such as during minor surgical procedures or while in recovery when a rapid onset of pain relief is desired.

Additionally, understanding the classification of opioids and their durations of action can help in clinical settings, allowing healthcare providers to effectively choose pain management options for patients based on their specific needs and the anticipated duration of the procedure or treatment.
