Mechanism of action

Paroxetine is a selective serotonin reuptake inhibitor (SSRI) that blocks the serotonin transporter protein, preventing the reabsorption of serotonin from the synaptic cleft back into presynaptic neurons. This increases serotonin concentration in the synapse, enhancing neurotransmission and improving mood regulation. The hydrochloride hydrate formulation is the salt form used for oral pharmaceutical administration.
