Description
O-desmethyltramadol (O-DSMT, Desmetramadol , INN) it is an opioid analgesic, an agonist of the m-opioid receptors, an active metabolite of tramadol and has a higher activity than its parent compound. This drug was first developed in the laboratories of Grunenthal GmbH in Germany, in the late 1970s..
Chemistry.
O-desmethyltramadol is an active metabolite of tramadol and has a related chemical structure. Tarmadol is metabolized by the liver enzyme CYP2D6, and O-desmethyltramadol does not need to be metabolized and is rapidly absorbed by the body.
Pharmacology, Pharmacodynamics.
All information presented in this section is based on data from mouse research reports and published research reports.
O-desmethyltramadol is an active agonist of the μ-opioid receptors and has a lower affinity for δ- and κ-opioid receptors, its action is associated with G-proteins.
(+)- the two tramdol enantiomers show different pharmacological exposure profiles, both of them are inactive as serotonin reuptake inhibitors, but (-) – the enantiomer remains active and acts as a norepinephrine reuptake inhibitor. Its effects could be useful in the treatment of pain, where there is a likelihood of interactions compared to other opioids.
O-desmethyltramadol is a partial antagonist of the serotonin 5-HT2C receptor, where inhibition of the receptor is a factor in the antidepressant effects of agomelatin and maprotilin. It causes the release of dopamine and norepinephrine, which regulates mood and anxiety.
Side effects.
With improper use, high dosage, as well as use with other drugs, side effects such as dizziness, nausea, itching and constipation, physical and psychological addiction are possible.
Use as a recreational tool.
O-desmethyltramadol(O-DSMT) used to be sold as a Krypton blend.
Medical applications.
O-desmethyltramadol was not marketed as a medical drug due to the risk of abuse.
