This page compares them: when each is used, how the mechanisms and indications differ, and whether the question "Lantus vs Citalopram" makes sense to ask at all.

They belong to different therapeutic classes and are chosen for different indications.

Mechanisms compared
Lantus: Insulin glargine binds the insulin receptor with similar affinity to human insulin, activating intracellular signalling that increases glucose uptake in muscle and adipose tissue, suppresses hepatic glucose production an… Citalopram: Citalopram selectively inhibits the serotonin reuptake transporter, increasing synaptic serotonin availability with limited affinity for noradrenaline transporters or other receptors.
