Mechanism of Action

The mechanism of action is not exactly known, but specialists do know that it acts on noradrenergic and serotonergic nociception, while its metabolite O-desmethyltramadol ((O-DSMT) acts on the µ-opioid receptor.

The peak plasma concentration of this drug after oral intake is 1.6 to 1.9 hours. It completely penetrates the blood-brain barrier (acting as a strict control point for what can enter the brain).

Is It Safe During Pregnancy or Breastfeeding?

According to the US Food and Drug Administration classification of drugs, this opioid falls under category C.

Data from studies conducted on animal models established that this medication can cause moderate to severe side effects in developing babies.

In addition, this drug has been shown to cross the placental barrier (an important tissue barrier that separates the developing fetus from the mother).

There are case reports of withdrawal symptoms in newborn babies following exposure to the medication in the womb.

Moreover, the US FDA recommends against the use of the medication during breastfeeding since it passes to the infant through breast milk. However, the amount of drug excreted into breastmilk is much less than the dosage which has been given to newborn babies for analgesia.


People taking this man-made opioid should not combine it with alcoholic beverages since both substances are CNS depressants, which actually means they can slow down brain function when mixed.

In addition, mixing this opioid with alcohol can significantly increase the chances of overdosing on either substance.
