Levomethadone is a synthetic opioid analgesic medication used to treat severe pain. It is a long-acting form of the opioid agonist methadone, and is the levorotatory isomer of that compound. It is available in oral, intramuscular, subcutaneous, rectal, and intravenous forms. Levomethadone is used to treat pain and opioid dependence, although it is not approved for this use in the United States. Common side effects include constipation, nausea, drowsiness, dizziness, and headache.
Levomethadone is a synthetic opioid medication used for two main purposes:
- Pain Management: It acts as an analgesic, relieving moderate to severe pain [1].
- Opioid Dependence Treatment: It's a crucial part of opioid maintenance therapy (OMT) programs, helping people overcome addiction to drugs like heroin and morphine [2].
Here's a deeper look at levomethadone:
- How it Works: Levomethadone binds to opioid receptors in the brain, producing pain-relieving and anti-craving effects. It's the active component of methadone, but is roughly twice as potent [1, 3].
- Dosage and Availability: Due to its potency, levomethadone is typically prescribed and dispensed in a controlled medical setting to ensure proper use [2].
It's important to note:
- Levomethadone is a powerful medication and can be addictive if not used as directed.
- It can cause side effects such as drowsiness, constipation, and nausea.
- Levomethadone use requires regular monitoring by a healthcare professional.
Levomethadone compared to methadone:
While both are opioids used for pain management and OMT, levomethadone offers potential advantages like a lower risk of certain side effects [2, 3]. However, methadone is generally the preferred medication due to its wider availability and established use in OMT programs.
