“May all be happy, may all be healed, may all be at peace and may no one ever suffer."
Citalopram is bicyclic phthalane derivative and a selective serotonin re-uptake inhibitor, with little or no effect on noradrenaline, dopamine and GABA re-uptake. The inhibitory activity explains the antidepressant property of citalopram. It has no or very low affinity for 5-HT1AA, 5-HT2A, D1 and D2 receptors, α1, α2, β-adrenergic, histamine H1, muscarinic, cholinergic, benzodiazepine and opioid receptors.
