Low level of noradrenaline is the cause of depression. What type of drugs are needed to cure this problem? Name two drugs.


Anti-depressant drugs are needed to counteract the effect of depression. These drugs function by inhibiting the enzymes catalysing the degradation of the neurotransmitter, noradrenaline. As a result, the important neurotransmitter is slowly metabolised and then it can activate its receptor for longer periods of time.

Two anti-depressant drugs are:


(i) Iproniazid


(ii) Phenelzine
