They belong to different therapeutic classes and are chosen for different indications.

Mechanisms compared
Paxil: Paroxetine selectively inhibits the serotonin reuptake transporter (SERT), increasing synaptic serotonin availability. Lamotrigine: Lamotrigine is a phenyltriazine that selectively blocks voltage-gated sodium channels, stabilising neuronal membranes and reducing the release of excitatory neurotransmitters, particularly glutamate.
When the comparison makes sense
