In ten% in the samples, aminorex was detected, albeit the concentrations ended up close to the detection limit119. In two publish mortem urine samples with very superior levamisole concentrations, aminorex quantification was also significant119. Eiden et al

It has more info been hypothesized the psychomotoric results connected with aminorex involved interactions with brain receptors or releasing dopamine37. The attribution of consequences to extracellular dopamine may be verified for 4-MAR (for enantiomeric discrepancies see over), Although the cited experiments did not incorporate steps of extracellular norepinephrine, that might also be implicated while in the behavioral consequences in rats149,150,219,220.
This retrospective study highlighted that anticoagulant therapy with warfarin in aminorex-caused pulmonary hypertension had useful outcomes on their survival time.
