SNRIs are another type of antidepressant medication that increase levels of norepinephrine and serotonin in the brain by inhibiting their reabsorption into neurons.
Imagine SNRIs as bouncers at a club where norepinephrine and serotonin are party-goers. Normally, these party-goers would leave the club early (get reabsorbed into neurons), but our bouncers (SNRIs) keep them inside longer so they can continue to have fun (increase mood-enhancing effects).
Norepinephrine: A neurotransmitter involved in arousal and alertness.
Dual-action Antidepressants: Antidepressants like SNRIs that work on two neurotransmitters instead of just one.
Reuptake Inhibition: The process by which reuptake inhibitors block absorption of neurotransmitters back into neurons.
