Application

O-Desmethyltramadol has been used for the pharmacokinetic studies of tramadol metabolites in goats.
O-Desmethyltramadol may be used as an opioid to test its effect on the cytotoxic functionality of human natural killer cells. It may also be used as an internal standard in gas chromatography-mass spectrometry (GC-MS) for the quantification of tramadol based derivatives from human urine samples.

Biochem/physiol Actions

O-Desmethyltramadol has a high affinity towards opioid receptors and is responsible for the analgesic effect of the μ-opioid receptor
Metabolite of tramadol

General description

O-Desmethyltramadol, an opioid, is an active metabolite of tramadol. The enzyme key for its production is polymorphic cytochrome P450 isoenzyme 2D6 (CYP2D6).

Four randomized, double-blind, placebo-controlled, 4-period drug-drug interaction studies were conducted in healthy subjects to evaluate the pharmacokinetic and pharmacodynamic (PD) interactions between mirogabalin and commonly used central nervous system depressants. Mirogabalin or placebo was administered alone or with single-dose lorazepam

Aim: Tramadol is widely used to treat acute, chronic, and neuropathic pain. Its primary active metabolite, O-desmethyltramadol (M1), is mainly responsible for its µ-opioid receptor-related analgesic effect. Tramadol is metabolized to M1 mainly by the cytochrome P450 (CYP) 2D6 enzyme

The objective of this study was to investigate the possible interaction of shikonin and β,β-dimethylacrylshikonin (DSK) with tramadol. Human liver microsome (HLM) and rat liver microsome (RLM) incubation experiments were carried out to assess the half-maximal inhibitory concentration (IC50 )

Inhibition of intestinal peristalsis is a major side effect of opioid analgesics. Although tramadol is an opioid-like analgesic, its effect on gut motility is little known. Therefore, the effect of (+)-tramadol, (-)-tramadol and the major metabolite O-desmethyltramadol on intestinal peristalsis
