View in Spanish: ISRS

SSRI
A type of drug that is used to treat depression. SSRIs 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. Also called selective serotonin reuptake inhibitor.
