Description

Citalopram is an orally administered selective serotonin reuptake inhibitor (SSRI) with a chemical structure unrelated to that of other SSRIs, tricyclic, tetracyclic or other available antidepressant agents. The mechanism of action of Citalopram as an antidepressant is presumed to be linked to potentiation of serotonergic activity in central nervous system resulting from its inhibition of CNS neuronal reuptake of serotonin (5-HT).

Citalopram has also been given in variety of anxiety disorders including obsessive-compulsive disorder and social phobia. It is also effective in generalized anxiety disorder, post-traumatic stress disorder, premenstrual syndrome, idiopathic Parkinson's disease and eating disorder.

Pregnancy

There are no adequate and well-controlled studies in pregnant women; therefore, Citalopram should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Lactation

Citalopram is excreted in human breast milk. So, the decision whether to continue or discontinue either nursing or Citalopram therapy should take into account the risks of Citalopram exposure for the infants and the benefits of Citalopram treatment for the mother.
