Norpethidine Definition

Norpethidine is a synthetic opioid analgesic that was first introduced as a substitute for pethidine. It is a white, bitter, crystalline powder with a molecular formula of C15H21NO2. Norpethidine has a highly addictive potential and was widely used in the past for pain relief, but due to its addictive and potentially harmful properties, it is now controlled or banned in many countries.
