escitalopram, Lexapro

👤by AP 0 comments 🕔Wednesday, December 10th, 2014

DRUG CLASS AND MECHANISM: Escitalopram is an oral drug that is used for treating depression and generalized anxiety disorder. Chemically, escitalopram is similar to citalopram (Celexa). Both are in a class of drugs called selective serotonin reuptake inhibitors (SSRIs), a class that also includes fluoxetine (Prozac), paroxetine (Paxil) and sertraline (Zoloft). SSRIs work by affecting neurotransmitters in the brain, the chemical messengers that nerves use to communicate with one another. Neurotransmitters are made and released by nerves and then travel to other nearby nerves where they attach to receptors on the nerves. Not all of the neurotransmitter that is released binds to receptors and, instead, is taken up by the nerves that produced them. This is referred to as "reuptake." Many experts believe that an imbalance of neurotransmitters is the cause of depression. Escitalopram prevents the reuptake of one neurotransmitter, serotonin, an action which results in more serotonin in the brain to attach to receptors. The FDA approved escitalopram in August 2002.
