Which of the following classes does escitalopram belong to?
Show Hint

Updated On: Jun 24, 2026
- Tricyclic antidepressants
- Selective serotonin reuptake inhibitors
- Norepinephrine reuptake inhibitors
- Serotonin–norepinephrine reuptake inhibitors
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Antidepressants are divided into classes based on which brain chemicals (neurotransmitters) they affect and how. One major class works by blocking the reuptake of serotonin specifically, leaving more serotonin available in the brain to improve mood.
Step 1: Escitalopram blocks the serotonin transporter, preventing serotonin from being taken back up into nerve cells. It acts mainly and selectively on serotonin, with little effect on norepinephrine.
Step 2: A drug that selectively blocks serotonin reuptake is, by definition, a Selective Serotonin Reuptake Inhibitor (SSRI). Escitalopram is a classic example of an SSRI, so the other classes (TCAs, NRIs, SNRIs) do not fit.
Answer: Option (2) — Escitalopram belongs to the Selective serotonin reuptake inhibitors. (2)
