What class of medication does Citalopram (Celexa) belong to?

Citalopram, marketed under the name Celexa, is classified as an SSRI antidepressant, which stands for selective serotonin reuptake inhibitor. This class of medications is primarily used to treat depression and anxiety disorders by increasing levels of serotonin in the brain. Serotonin is a neurotransmitter that plays a key role in mood regulation, and by inhibiting its reuptake, SSRIs help to elevate mood and alleviate symptoms of depression.

The mechanism of action of SSRIs, including Citalopram, focuses on the selective inhibition of the serotonin transporter, which leads to increased serotonergic activity in the central nervous system. This focus on serotonin reuptake makes SSRIs a commonly prescribed and effective option for individuals suffering from depressive and anxiety disorders, demonstrating their importance in mental health treatment.
