Description

Nomifensine was developed by Hoechst AG as a potent inhibitor of noradrenaline, dopamine, and 5-HT uptake displayed antidepressant activity. It was first marketed in the UK in 1977 for the treatment of depression. Between 1977 and 1982 there were reports of hemolytic anemia in association with the drug, and this suspected adverse reaction was included in the 1981 edition of the data Sheet Compendium. FDA published a notice of its determination that Merital capsules were removed from the market for safety reasons.

The effect of nomifensine on the uptake of 5-hydroxytryptamine (5-HT) and dopamine (DA) into human platelet-rich plasma has been studied. A significant inhibition of DA uptake was observed at nomifensine 10(-6) M. 5-HT uptake was significantly inhibited only at nomifensine 10(-4) M or more. It was concluded, that the human platelet may be used as a model for studying DA uptake as well as that of 5-HT.
