Lab comments:
Regarding Metamizole / 4-Methylaminoantipyrine:

Our current GC/MS protocol can not distinguish between metamizole and 4-methylaminoantipyrine. 4-Methylaminoantipyrine is a metabolite of metamizole. Their mass spectra are indistinguishable because metamizole undergoes thermal decomposition to 4-methylaminoantipyrine and aminopyrine during GC-MS analysis. The chemical identified in this sample could be either Metamizole or 4-Methylaminoantipyrine, or a combination of the two.
Round light yellow tablet with 'M' on one side, '30' and break line on the other. Counterfeit oxycodone. [Drugsdata accepts partial tablets and pulverized tablets by prior approval only.]
