Medical Definition of Selective serotonin reuptake inhibitor Selective serotonin reuptake inhibitor: A selective serotonin reuptake inhibitor (SSRI) is one of the commonly prescribed drugs for treating depression. SSRIs affect the chemicals that nerves in the brain use to send messages to one another. These chemical messengers, called neurotransmitters, are released by one nerve and taken up by other nerves.
An SSRI is neither an antagonist of agonist. SSRI's do not directly affect the post-synaptic neuron which is the case for both antagonists and agonists. SSRI's also do not increase the amount of serotonin released. So what is a SSRI? A SSRI is a drug that blocks the reuptake of serotonin on the pre-synaptic neuron.
