Dihydromorphine is a semisynthetic opioid analgesic sold under the trade names Paramorfan or Paramorphan for treatment of pain. Dihydromorphine is also a primary active metabolite of the analgesic opioid drug dihydrocodeine. This Snap-N-Spike® Reference Solution is suitable for use as starting material in calibrators or controls for a variety of LC/MS or GC/MS applications from urine drug testing and pain prescription monitoring to pharmaceutical research.

Dihydrocodeine is metabolized to dihydromorphine via the isoenzyme cytochrome P450 2D6, whose activity is determined by genetic polymorphism. The importance of the dihydromorphine metabolites for analgesia in poor metabolizers is unclear. The aim of this study was to assess the

A sensitive and specific method was developed for the determination of dihydrocodeine and its metabolite dihydromorphine in human serum using codeine and morphine as internal standards. Measurement is performed with GC-tandem MS after one simple extraction step and derivatization to
CE-ESI multistage IT-MS (CE-MS(n), n < or = 4) and computer simulation of fragmentation are demonstrated to be effective tools to detect and identify phase I and phase II metabolites of hydromorphone (HMOR) in human urine. Using the same CE

A high-performance liquid chromatographic assay for the oxidative metabolites of dihydrocodeine, nordihydrocodeine and dihydromorphine, formed in human liver microsomal incubations, is described. A simple solvent extraction followed by reversed-phase high-performance liquid chromatography with UV detection allows quantification of both metabolites

Initial confinement of opiate receptors to the nervous system has recently been broadened to several other cell types. Based on the well established hypotensive effect of morphine, we hypothesized that endothelial cells may represent a target for this opiate substance.
