Description

The antidepressant action of escitalopram is presumably linked to the potentiation of serotonergic activity in the central nervous system (CNS) resulting from its inhibitory effect on the reuptake of 5-HT from the synaptic cleft. Escitalopram is the S-enantiomer of the racemate citalopram and is the enantiomer to which the therapeutic activity is attributed. Pharmacological studies have shown that the R-enantiomer is not inert but counteracts the serotonin-enhancing properties of the S-enantiomer in citalopram. Escitalopram has high affinity for the primary binding site and an allosteric modulating effect on the serotonin transporter.

Side Effects

Escitalopram is well tolerated by most people. The most commonly reported side-effects of Escitalopram are nausea, insomnia, problems with ejaculation, drowsiness, increased sweating and fatigue. Most of the side-effects experienced by patients taking Escitalopram are mild and go away with continued treatment and usually do not cause patients to stop taking Escitalopram.

Precautions

Escitalopram should be used with caution in patients with epilepsy (avoid if poorly controlled, discontinue if convulsions develop), cardiac disease, diabetes mellitus, susceptibility to angle-closure glaucoma, a history of mania or bleeding disorders (especially gastro-intestinal bleeding) and if used with other drugs that increase the risk of bleeding, hepatic impairment, renal impairment, pregnancy and breast-feeding. It should also be used with caution in those receiving concurrent electroconvulsive therapy. Escitalopram may also impair performance of skilled tasks (e.g. driving).

Use in Pregnancy & Lactation

Category C. No relevant epidemiological data or well controlled studies in pregnant women are available for escitalopram. Escitalopram has had limited use in pregnancy without a reported increase in birth defects. Neonates should be observed if maternal use of Escitalopram continues into the later stages of pregnancy, particularly in the third trimester. Abrupt discontinuation should be avoided during pregnancy. This drug should be used during pregnancy only if clearly needed and only after careful consideration of the risk/benefit. It is expected that escitalopram, like citalopram, will be excreted into human breast milk.
