Pharmacology
Escitalopram is a selective inhibitor of serotonin (5-HT) re-uptake. The inhibition of 5-HT re-uptake is the only likely mechanism of action explaining the pharmacological and clinical effects of escitalopram. Escitalopram has no or low affinity for a number of receptors including 5-HT1A, 5-HT2, DA D1 and D2 receptors, α1-, α2-, β-adrenoceptors, histamine H1, muscarine cholinergic, benzodiazepine and opioid receptors.
Dosage & Administration
Adults: The initial dose of Escitalopram Oxalate is 10 mg once daily. (A fixed dose trial of Escitalopram Oxalate demonstrated the effectiveness of both 10 mg and 20 mg of Escitalopram Oxalate, but failed to demonstrate a greater benefit of 20 mg over 10 mg.)
If the dose is increased to 20 mg, this should occur after a minimum of one week.
Interaction
Escitalopram should not be started until 2 weeks after stopping an MAOI. Conversely, an MAOI should not be started until at least a week after escitalopram or related antidepressant has been stopped.
Contraindications
Concomitant use in patients taking monoamine oxidase inhibitors (MAOIs) is contraindicated. Concomitant use in patients taking pimozide is contraindicated. Esita is contraindicated in patients with a hypersensitivity to escitalopram or citalopram or any of the inactive ingredients.
