Paroxetine: the science

  1. Sexual arousal triggers a neurological response in the brain. This signals the body to react physically (when it comes to both an erection and ejaculation).
  2. Serotonin is a critical component in this neurological response. The neurotransmitter is affected by paroxetine, which is a selective serotonin reuptake inhibitor (SSRI).
  3. Essentially, paroxetine increases the activity of serotonin in the brain and this delays the time taken for the brain to trigger ejaculation.
