Morphine is highly addictive and prone to abuse. [12] If one's dose is reduced after long-term use, opioid withdrawal symptoms may occur. [12] Caution is advised for the use of morphine during pregnancy or breastfeeding, as it may affect the health of the baby. [12] [2] Morphine was first isolated in 1804 by German pharmacist Friedrich Sertürner.
In contrast to natural morphine, the unnatural enantiomer has no affinity or efficacy for the mu opioid receptor and therefore has no analgesic effects. To the contrary, in rats, (+)-morphine acts as an antianalgesic and is approximately 71,000 times more potent as an antianalgesic than (−)-morphine is as an analgesic.
