Levomethorphan
Levomethorphan
Levomethorphan (pronounced: levo-meth-or-phan) is a morphinan derivative and isomer of dextromethorphan. It is a potent opioid analgesic drug that is not commonly used due to its potential for abuse and addiction.
Etymology
The term "Levomethorphan" is derived from the prefix "levo-", which refers to the left-handed isomer of a chiral molecule, and "methorphan", which is a term used to describe a group of opioid drugs.
Pharmacology
Levomethorphan acts as an agonist at the mu-opioid receptor, which is the main site of action for the most commonly used opioids. It has similar effects to other opioids, including analgesia, sedation, and respiratory depression.
Medical Uses
Levomethorphan is used primarily for the treatment of severe pain. However, due to its potential for abuse and addiction, it is not commonly used in clinical practice.
Side Effects
Common side effects of Levomethorphan include nausea, vomiting, constipation, and respiratory depression. It can also cause psychological effects such as euphoria and hallucinations, which contribute to its potential for abuse.
