Fluvoxamine is a potent selective serotonin reuptake inhibitor with around 100-fold affinity for the serotonin transporter over the norepinephrine transporter. It has negligible affinity for the dopamine transporter or any other site, with the sole exception of the σ1 receptor. It behaves as a potent agonist at this receptor and has the highest affinity (36 nM) of any SSRI for doing so. This may contribute to its antidepressant and anxiolytic effects and may also afford it some efficacy in treat… WebCytochrome P450 inhibition of selective serotonin reuptake inhibitors CYP1A2 CYP2C19 CYP2D6 CYP3A4 Fluoxetine 3213 Fluvoxamine 1 2 2/3 1/2 Citalopram 333NA Paroxetine 3312/3 Setraline 3332/3 1: substantial, 2: moderate, 3: weak, NA: information not available.
