Neuronal
Excitability
The inhibition of dopamine
reuptake receptors by
Mazindol causes more
dopamine to accumulate in
the synapse, causing the
continual activation of the
D4 Dopamine receptor
Activation of D4 dopamine
receptors activates the Gi
signalling cascade which
leads to reduced cAMP.
Presynaptic Neuron
Cytosol
Synaptic Vesicle
Postsynaptic Neuron
Cytosol
Dopamine is produced in the
Ventral Tegmental Area of
the brain
Prefrontal Cortex
Reduced cAMP results in
decreased neural
excitability. This results
in reduced movement and
impulsivity. Although the
exact mechanisms are
unknown.
Synapse
Prefrontal Cortex
Increased dopamine activates
D4 dopamine receptors in the
prefrontal cortex
In low doses, Mazindol
selectively activates
dopamine neurotransmission
Blood-Brain Barrier
Diffusion
Mazindol will also block the
binding of cocaine to the
dopamine reuptake receptors
