Lexapro

What is Lexapro?

Lexapro is a prescription medicine used to treat depression. It is important to talk with your healthcare provider about the risks of treating depression and also the risks of not treating it. You should discuss all treatment choices with your healthcare provider. Lexapro is also used to treat major Depressive Disorder (MDD) and generalized Anxiety Disorder (GAD)

Talk to your healthcare provider if you do not think that your condition is getting better with Lexapro treatment.

Description

Lexapro® contains escitalopram oxalate, an orally administered selective serotonin reuptake inhibitor (SSRI). Escitalopram is the pure S-enantiomer (single isomer) of the racemic bicyclic phthalane derivative citalopram. Escitalopram oxalate is designated S-(+)-1-[3(dimethyl-amino)propyl]-1-(p-fluorophenyl)-5-phthalancarbonitrile oxalate with the following structural formula:

• The molecular formula is C20H21FN2O
• • C2H2O4 and the molecular weight is 414.40.

Escitalopram oxalate occurs as a fine, white to slightly-yellow powder and is freely soluble in methanol and dimethyl sulfoxide (DMSO), soluble in isotonic saline solution, sparingly soluble in water and ethanol, slightly soluble in ethyl acetate, and insoluble in heptane.

Lexapro is available as tablets for oral administration.

Lexapro tablets are film-coated, round tablets containing 6.38 mg, 12.75 mg, 25.50 mg escitalopram oxalate in strengths equivalent to 5 mg, 10 mg, and 20 mg, respectively, of escitalopram base. The 10 and 20 mg tablets are scored. The tablets also contain the following inactive ingredients: talc, croscarmellose sodium, microcrystalline cellulose/colloidal silicon dioxide, and magnesium stearate. The film coating contains hypromellose, titanium dioxide, and polyethylene glycol.

Lexapro oral solution contains 1.29 mg/ml escitalopram oxalate equivalent to 1 mg/mL escitalopram base. It also contains the following inactive ingredients: sorbitol, purified water, citric acid, sodium citrate, malic acid, glycerin, propylene glycol, methylparaben, propylparaben, and natural peppermint flavor. The oral solution is not currently marketed.

    Mechanism of Action

The mechanism of antidepressant action of escitalopram, the S-enantiomer of racemic citalopram, is presumed to be linked to potentiation of serotonergic activity in the central nervous system (CNS) resulting from its inhibition of CNS neuronal reuptake of serotonin (5-HT).

What is the most important information I should know about Lexapro?

Lexapro and other antidepressant medicines may cause serious side effects, including:

1. Suicidal thoughts or actions

• Lexapro and other antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, or young adults within the first few months of treatment or when the dose is changed.

• Watch for these changes and call your healthcare provider right away if you notice:
  • New or sudden changes in mood, behavior, actions, thoughts, or feelings, especially if severe
  • Pay particular attention to such changes when Lexapro is started or when the dose is changed.

Keep all follow-up visits with your healthcare provider and call between visits if you are worried about symptoms.
