SSRI

A type of drug that is used to treat depression and some other conditions. SSRIs stop or delay the body from reabsorbing a substance called serotonin, which leaves more of it available for the body to use. Raising serotonin levels can help regulate mood, appetite, digestion, sleep, and many other bodily functions. SSRIs include drugs such as citalopram, escitalopram, fluoxetine, paroxetine, and sertraline. Also called selective serotonin reuptake inhibitor.
