NCI: A type of drug that is used to treat depression. Selective serotonin reuptake inhibitors slow the process by which serotonin (a substance that nerves use to send messages to one another) is reused by nerve cells that make it. This increases the amount of serotonin available for stimulating other nerves.,NCI: Any agent that increases the extracellular level of the neurotransmitter serotonin (5-HT) by inhibiting its reuptake into the presynaptic cell. Increased level in the synaptic cleft prolongs the action of 5-HT on the postsynaptic receptor. This type of agent is typically used as an antidepressant and in the treatment of anxiety disorders and some personality disorders. They are also typically effective and used in treating some cases of insomnia.
