Mechanism of action

Dapoxetine works by inhibiting the reuptake of serotonin at the synaptic cleft, thereby increasing serotonin availability in neural pathways that regulate ejaculation. The drug has a rapid onset and short half-life, making it suitable for on-demand dosing prior to sexual activity. Enhanced serotonergic neurotransmission in the brain regions controlling ejaculation results in prolonged time to ejaculation and improved control.
