Mechanisms compared
Celexa: Citalopram selectively inhibits the serotonin reuptake transporter, increasing synaptic serotonin availability with limited affinity for noradrenaline transporters or other receptors. Cetirizine: Cetirizine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine released by mast cells during allergic responses.
