GENERIC NAME: citalopram
BRAND NAME: Celexa
DRUG CLASS AND MECHANISM: Citalopram is an antidepressant medication that affects neurotransmitters, the chemicals that nerves within the brain use to communicate with each other. Neurotransmitters are manufactured and released by nerves and then travel and attach to nearby nerves. Thus, neurotransmitters can be thought of as the communication system of the brain. Many experts believe that an imbalance among neurotransmitters is the cause of depression. Citalopram works by preventing the uptake of one neurotransmitter, serotonin, by nerve cells after it has been released. Since uptake is an important mechanism for removing released neurotransmitters and terminating their actions on adjacent nerves, the reduced uptake caused by citalopram results in more free serotonin in the brain to stimulate nerve cells. Citalopram is in the class of drugs called selective serotonin reuptake inhibitors (SSRIs), a class that also contains fluoxetine (Prozac), paroxetine (Paxil) and sertraline (Zoloft). Citalopram was approved by the FDA in July 1998.
PRESCRIBED FOR: Citalopram is used for the management of depression. Citalopram also is used for treating obsessive compulsive disorder (OCD), panic disorder, premenstrual dysphoric syndrome (PMDD), anxiety disorder, and posttraumatic stress disorder.
