Escitalopram tablets contain escitalopram, a selective serotonin reuptake inhibitor (SSRI), present as escitalopram oxalate salt. 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 C 20 H 21 FN 2 O•C 2 H 2 O 4 and the molecular weight is 414.40. Escitalopram oxalate USP occurs as a white to almost white, crystalline 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. Escitalopram tablets USP, for oral use, are film-coated, containing 6.38 mg, 12.77 mg, 25.54 mg escitalopram oxalate USP 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: butylated hydroxyl anisole, butylated hydroxy toluene, colloidal silicon dioxide, croscarmellose sodium, magnesium stearate, microcrystalline cellulose, silicified microcrystalline cellulose, and talc.
