Mechanism and action
Toprol XL: Metoprolol selectively blocks beta-1 adrenergic receptors in the heart, reducing heart rate, contractility and atrioventricular conduction velocity, and lowering myocardial oxygen demand. Zoloft: Sertraline acts by selectively blocking the serotonin transporter, preventing serotonin reuptake from the synaptic cleft and increasing synaptic serotonin concentration.

When Zoloft is preferred
