Nonclinical studies have shown that paroxetine is an SSRI. BRISDELLE is not an estrogen, and its mechanism of action for the treatment of VMS is unknown. Pharmacodynamics. Studies at clinically relevant doses in humans have demonstrated that paroxetine blocks the uptake of serotonin into human platelets. This antidepressant class, first discovered in the 1950s, inhibits the action of an enzyme called monoamine oxidase, whose role it is to break down monoamines. 7 By blocking this effect, more neurotransmitters are available for use in mood regulation. Examples of MAOIs include: Emsam (selegiline) 3 Marplan (isocarboxazid) Nardil (phenelzine)The impact of CYP2D6 activity in drug metabolism is further complicated by the activity of the drug itself on CYP2D6. Some SSRIs, such as paroxetine, fluoxetine, and citalopram, as well as statins, are known to inhibit CYP2D6 activity and may make EMs resemble IMs or PMs.Finally, since most SSRIs are also substrates of CYP2D6, SSRIs that both inhibit and are metabolized by CYP2D6 can inhibit ...This mechanism explains most of the antidepressant effects of SSRIs ( See figure 4 ). Figure 4. Step 3- activation of serotonin production and release (Stahl, 2010). Once the neuron has already begun to segregate higher levels of serotonin, another mechanism of action of SSRIs that has not been effective so far is becoming relevant.Paroxetine affects neurotransmitters, the chemicals that nerves within the brain use to communicate with each other.
